Technical Field

The present application relates to the field of communications technologies, and in particular, to a file sharing method, system, apparatus, computing device, and terminal device.

Background

With the continuous development of internet technology, files may need to be shared in more and more scenes, for example, in a conference scene, a conference host needs to show documents, for example, an annual performance report of a company. The conventional display mode is that a conference host transmits a file to be displayed to a computer in a conference room in a mode of USB flash disk copy or network transmission and the like, and then the file to be displayed is displayed on a screen through a projector, so that local participants in the conference room can watch the file displayed in a projection manner.

For a remote conference (e.g., a teleconference or a video conference) scenario, a file to be shown may be shared with a remote participant through a file sharing function provided by some social applications, so that the remote participant can also view a file to be shown by a conference host.

Therefore, for example, in a local conference, a remote conference and other scenes, the file sharing technology is a considerable problem because the file sharing requirement is high.

Furthermore, the term "comprises" and any variations thereof are intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus. The "plurality" in the present application may mean at least two, for example, two, three or more, and the embodiments of the present application are not limited.

In addition, the term "and/or" herein is only one kind of association relationship describing an associated object, and means that there may be three kinds of relationships, for example, a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this document generally indicates that the preceding and following related objects are in an "or" relationship unless otherwise specified.

Some terms referred to herein are explained below to facilitate understanding by those skilled in the art.

1. The online document capable of being cooperated by multiple persons is an online document capable of supporting the cooperation of multiple persons, the online document is displayed through a lightweight Web page, the document can be checked and edited by opening the Web page, the document can be stored in real time at the cloud end, the real-time editing of multiple persons can be realized, and the authority is safe and controllable.

2. The virtual presentation room, which is a logical resource for managing presentation of an online document in the embodiment of the present application, may be understood as a set of all participants participating in a certain file sharing, where the set includes a presenter (corresponding to a presentation terminal) and a viewer (corresponding to a viewing terminal) performing the file sharing.

The virtual demonstration rooms are created and managed by the demonstration server, the demonstration server can configure terminal devices included in each virtual demonstration room, the watching permission levels and the editing permission levels of the terminal devices in the rooms, and can control switching among the virtual demonstration rooms.

In addition, the virtual presentation room not only supports sharing and management of online documents, but also supports transmission of audio and video data, so as to realize a remote telephone conference, a network conference, a video conference and the like.

3. The sharing terminal is a terminal for performing file presentation in the virtual presentation room, and may also be referred to as a presentation terminal mentioned later.

4. The shared terminal may also be referred to as a viewing terminal hereinafter, where the shared terminal views the online document shared by the sharing terminal in the virtual presentation room.

As described above, currently, file sharing is required in various scenarios such as local conferences and remote conferences (including teleconference and web conference), so the file sharing technology is worthy of research. In the related art, for example, the following ways may be used to share files.

(1) For example, in a local conference, a file to be shared (e.g., a PPT file) may be transmitted to a conference room computer through usb disk copy or network transmission, and then the PPT file is displayed in a projection manner through a projector connected to the conference room computer, so that each participant in the conference room can see the PPT file, thereby realizing file sharing.

In the above manner, the operation of the file is considered to have potential safety hazards, so that the file diffusion is difficult to avoid, and the protection of information safety is not facilitated. In addition, a computer and a projector which can be connected with the projector are required, the hardware requirement is high, the whole process involves a series of operations such as copying files and connecting the projector, the operation is troublesome, and the flow performance of the conference is influenced. In addition, the scheme can only support local conferences and cannot support file sharing of remote conferences.

(2) At present, some applications (for example, social applications) can support multi-user audio and video calls and screen sharing operations, and a user can share files through screen sharing.

In the mode, the screen sharing and the audio and video conversation are carried out simultaneously, the requirement on bandwidth is high, the blockage is easy to occur, and the fluency of the conference is influenced. And requires that all participants must install the designated application, not taking advantage of widespread use.

(3) At present, some applications (for example, social applications) may support a multi-user audio/video call and a file sending function, a conference host may send a file to each participant through a file sharing function of the social applications, and after all participants receive the file, the conference host may prompt each participant based on the audio/video call function of the social applications, for example, prompt the current page of explaining the PPT, and the like.

In the above manner, the conference participants passively view the shared file according to the voice prompt of the conference host, for example, the PPT page turning operation is performed, so that the asynchronization is easy to occur frequently, and the user experience is poor. But also may occur that the file cannot be opened or the presentation effect is incorrect after opening because the participant does not install the specified application. And after the file is sent to the participants, the file is difficult to avoid spreading out from the participants, which is not beneficial to the protection of the file security.

Several file sharing schemes in the prior art listed above all have some problems correspondingly. In view of this, an embodiment of the present application provides another technical solution for sharing a file, in which a presentation server may create a virtual presentation room (e.g., a first virtual presentation room), and return room information of the first virtual presentation room to a user, and then the user may initiate a presentation request for requesting to present an online document to the presentation server through a first terminal device, and the presentation server responds to the presentation request, so as to obtain document data corresponding to the first online document according to address information of the first online document carried in the presentation request, and further share the obtained document data to each terminal device in the first virtual presentation room, for example, broadcast the document data to all terminal devices in the room, and further each terminal device in the first virtual presentation room may present the received document data, so that a participant corresponding to each terminal device can synchronously view the first online document, thereby implementing synchronous online sharing of the file.

In the scheme, the online documents are shared in batch by establishing the virtual demonstration room, which is equivalent to multicast sharing of data of a terminal device group in the virtual demonstration room, and the file sharing efficiency is high, so that file synchronization among participants can be realized quickly, and the file sharing fluency is ensured. In addition, online documents supporting multi-user cooperation are shared, so that the online documents can be conveniently subjected to cooperation operation and synchronous updating by multiple users in real time, the file synchronization among the users is further improved, and the user experience is enhanced.

In order to better understand the technical solution provided by the embodiment of the present application, some brief descriptions are provided below for application scenarios to which the technical solution provided by the embodiment of the present application is applicable, and it should be noted that the application scenarios described below are only used for illustrating the embodiment of the present application and are not limited. In specific implementation, the technical scheme provided by the embodiment of the application can be flexibly applied according to actual needs.

Referring to fig. 1, fig. 1 is an application scenario to which the technical solution of the embodiment of the present application can be applied, where the application scenario includes a demonstration terminal 101, a plurality of viewing terminals (a viewing terminal 201, a viewing terminal 202, a viewing terminal 203), an online document server 301 and a demonstration server 302, where a user corresponding to the demonstration terminal 101 is represented by a presenter, that is, the presenter can share and demonstrate online documents through the demonstration terminal 101; the users corresponding to the viewing terminal 201, the viewing terminal 202, and the viewing terminal 203 are employee a, employee B, and the manager of the king, for example, employee a may view the online document shared by the presenter through the presentation terminal 101 through the viewing terminal 201, and the manager of the king may view the online document shared by the presenter through the presentation terminal 101 through the viewing terminal 203.

Taking the application scenario shown in fig. 1 as an example of performing a local conference in a conference room, when a presenter needs to share a file with each participant (i.e., employee a, employee B, and king manager), for example, sharing a PPT file locally stored by the presentation terminal 101, in order to facilitate sharing of the shared PPT file in a collaboratable online document manner, so that each participant can collaborate online by multiple people, the presenter can open a client of an online document application, and then send the PPT file to the online document server 301 providing a background service for the online document application through the client of the online document application, after receiving the PPT file, the online document server 301 converts the PPT file into an online document collaboratable by multiple people using corresponding transcoding components and encoding components, and can convert the PPT file into a Web page for presentation, because the Web page is light, when sharing with other terminals, the other terminals spend less viewing traffic, so that they can view smoothly, and other terminals can view the PPT file on-line smoothly through a URL Locator (URL) corresponding to the Web page, and thus, and the Web page can be viewed by a user repeatedly and the online document can be shared online and the online document can be shared by multiple people on-line, and the online document can be viewed smoothly. In addition, the content edited by the user is stored in the cloud in real time, so that the user does not need to worry about content loss after the equipment is powered off or disconnected, the effectiveness of editing operation is ensured, and repeated editing is reduced.

Further, after converting the PPT file uploaded by the presenter into a Web page, the online document server 301 returns the URL address corresponding to the Web page to the presentation terminal 101, and then the presentation terminal 101 can directly view the Web page corresponding to the PPT file through the URL address, and at the same time, the presentation terminal 101 can directly send the URL address to other terminal devices, where a user of the terminal device can also view the Web page corresponding to the PPT file after clicking and opening the URL address, or the presentation terminal 101 can also convert the URL address into a two-dimensional code and send the two-dimensional code to other terminal devices, and other terminals can present the Web page corresponding to the PPT file by scanning the two-dimensional code, that is, the terminal device 101 can invite other terminal devices to synchronously view the online document through the URL address or the two-dimensional code.

Further, the presenter may also initiate a file sharing request to the presentation server 302 through the presentation terminal 101, for example, the presenter may initiate the file sharing request to the presentation server 302 by inputting a predetermined website in a browser of the presentation terminal 101, and after detecting the file sharing request, the presentation server 302 determines that the user has a need to share a file, creates a virtual presentation room (for example, virtual presentation room 1), and returns room information of the virtual presentation room 1 to the presentation terminal 101, for example, returns a two-dimensional code and/or a character sequence (for example, a string of numbers) to the presentation terminal 101, where the character sequence corresponds to a room ID of the virtual presentation room 1, and the two-dimensional code carries the character sequence. The presenter may scan the two-dimensional code using the code scanning function of the presentation terminal 101 to join the virtual presentation room 1, or the user may join the virtual presentation room 1 by inputting the character sequence in a predetermined input area of an online document application running in the presentation terminal 101, or, since the presentation terminal 101 is a request end that directly initiates a file sharing request to the presentation server 302, the presentation server 302 may add the presentation terminal 101 to the created virtual presentation room 1 by default after returning room information to the presentation terminal 101, so the user does not need to perform any operation for joining the virtual presentation room. After joining virtual presentation room 1, the presenter may click on a "show immediately" button in the online document application, i.e., indicating that the file needs to be shared online, and further, the user may send the PPT file to presentation server 302 via the online document-converted URL address, i.e., initiate a presentation request to presentation server 302 for requesting presentation of the online document, specifically, for example, requesting presentation of the online document in virtual presentation room 1.

After receiving the URL address sent by the presentation terminal 101, the presentation server 302 sets a right for the presentation terminal 101 to share a document in the virtual presentation room 1, and after having the right, it indicates that the presentation terminal 101 can share an online document in the virtual presentation room 1, so that operations (e.g., an editing operation, an annotation operation, a marking operation, or a page turning operation) performed by a presenter on the PPT file displayed in the presentation terminal 101 can be synchronized to each viewing terminal in the virtual presentation room 1. In the embodiment of the present application, the room information of the virtual demonstration room may be a two-dimensional code, a character, a website address, or other forms. For example, the viewing terminal 1, the viewing terminal 2, and the viewing terminal 3 in fig. 1 are all previously added to the virtual presentation room 1 by scanning the two-dimensional code corresponding to the virtual presentation room 1. Further, the presentation server 302 may obtain document data of a Web page corresponding to the online document according to the URL address of the PPT file, and broadcast the obtained document data to each viewing terminal in the virtual presentation room 1, thereby implementing a file sharing function of the presentation terminal 101 in the virtual presentation room 1, that is, sharing the online document to other terminal devices in the virtual presentation room 1 except the presentation terminal 101 itself. For example, as shown in fig. 1, when a plant potting of one page of a PPT file is displayed in the demonstration terminal 101, each viewing terminal also synchronously displays the plant potting, and at this time, for example, a presenter frames the plant potting displayed in the demonstration terminal 101 in a red circle, each viewing terminal may also synchronously display the framing position and the framing line pattern of the red circle used for framing, and for example, when the presenter turns over the PPT file in the demonstration terminal 101 from page 4 to page 5, each viewing terminal also synchronously turns over the PPT file displayed in the Web page from page 4 to page 5 to synchronize with the demonstration of the demonstration terminal 101, that is, the demonstration terminal 101 has file demonstration permission in the virtual demonstration room 1, so all operations performed by the demonstration terminal 101 for the demonstration document can be synchronously shared with each terminal device (including the demonstration terminal 101 itself and all viewing terminals) in the simulated demonstration room 1.

In addition, it should be noted that each terminal device (including the presentation terminal 101 and all the viewing terminals) in fig. 1 is in communication connection with the online document server 301 and the presentation server 302 at the same time, so that information interaction between each terminal device and the online document server 301 and the presentation server 302 can be realized. And, the online document server 301 and the presentation server 302 may also maintain a communication connection, so that the presentation server 302 obtains the document data corresponding to the online document, i.e. the corresponding Web page data, from the online document server 301 according to the address information of the online document sent by the presentation terminal 101, and further broadcasts the obtained document data to each viewing terminal in the corresponding virtual presentation room.

Referring to another application scenario shown in fig. 2 again, compared to the application scenario shown in fig. 1, a request terminal 401 and a projector 402 are added in fig. 2, where the request terminal 401 may initiate a file sharing request to the presentation server 302 by inputting a predetermined website as in the presentation terminal 101 in fig. 1, and then the presentation server 302 returns room information of a virtual presentation room created based on the file sharing request to the request terminal 401 in a form of a two-dimensional code and/or a character sequence, and further, the presentation terminal 101 may scan the two-dimensional code displayed in the request terminal 401 or input the character sequence displayed by the request terminal 401 to join in the virtual presentation room. That is, the presentation terminal 101 in fig. 1 integrates the function of the requesting terminal 401 in fig. 2 initiating a file sharing request to the presentation server 302, whereas in fig. 2, the function of the requesting terminal 401 initiating a file sharing request to the presentation server 302 and the function of the presentation terminal 101 initiating a presentation request to the presentation server 302 are independent of the two terminal devices. In addition, in fig. 2, since the requesting terminal 401 is a terminal that issues a file sharing request to the presentation server 302, and the presentation server 302 can add the requesting terminal 401 to the created virtual presentation room when returning the room information of the created virtual presentation room to the requesting terminal 401, the user may not need to perform an operation of scanning a code or inputting a character sequence through the requesting terminal 401.

As shown in fig. 2, the request terminal 401 is a notebook computer, and the projector 402 is connected to the request terminal 401 and can project and display the content displayed in the request terminal 401.

The application scenarios shown in fig. 1-2 are, for example, a local conference scenario, that is, the requesting terminal 401, the presenting terminal 101, the viewing terminal 201, the viewing terminal 202, and the viewing terminal 203 are all in the same room (for example, room 1), and in another application scenario shown in fig. 3, the difference from fig. 2 is that another room (for example, room 2) is added in fig. 3, and a plurality of viewing terminals (for example, terminal devices respectively corresponding to employee C, employee D, and director) in room 2 are added, that is, a remote conference scenario is added in fig. 3, that is, all users in room 1 are in a local conference, and users in room 1 and users in room 2 are in a remote conference, for example, a video conference or a telephone conference. While the implementation of the individual viewing terminals in room 2 is the same as the viewing terminal in room 1 and will not be repeated here.

Through the sharing mode of the online document provided by the embodiment of the application, even though a user in the room 2 cannot see a presenter in the room 1, the user can synchronize with the presenter through the PPT file which is synchronously displayed in the corresponding watching terminal and the presentation terminal 101, and can know which page of the PPT the presenter explains in time, and even know which specific position of the page of the PPT. Meanwhile, the conference participant may also perform some editing operations in the viewing terminal, and the editing operations may be synchronously displayed to other terminals in the virtual presentation room according to the editing authority of the conference participant, or may also be synchronously displayed only in the viewing terminal of the conference participant.

Referring to the application scenario shown in fig. 4 again, compared to fig. 2, the requesting terminal 401 in fig. 2 is also a viewing terminal in fig. 4, and at this time, the virtual presentation room created by the presentation server 302 may include only the requesting terminal 401 and the presentation terminal 101, that is, the online document presented by the presentation terminal 101 is only displayed and shared by the viewing terminal, i.e., the requesting terminal 401.

Each of the presentation terminals 101, the request terminal 401, and the viewing terminals in fig. 1 to 4 may include a mobile phone, a tablet computer, a Personal Digital Assistant (PDA), a notebook computer, smart glasses, a smart helmet, and the like, which may have a camera, and the camera may scan a two-dimensional code, and then may quickly join a virtual presentation room created by the presentation server 302 by scanning the code, and the like. The online document server 301 and the presentation server 302 in fig. 1-4 may be a personal computer, a large and medium sized computer, a computer cluster, etc., the online document server 301 is used for providing a background application service for an online document application, and the presentation server 302 is used for providing a background service support for online presentation and sharing of a document.

To further illustrate the technical solutions provided by the embodiments of the present application, the following detailed description is made with reference to the accompanying drawings and the detailed description. Although the embodiments of the present application provide the method operation steps as shown in the following embodiments or figures, more or less operation steps may be included in the method based on the conventional or non-inventive labor. In steps where no necessary causal relationship exists logically, the order of execution of these steps is not limited to the order of execution provided by the embodiments of the present application. The method can be executed in sequence or in parallel according to the method shown in the embodiment or the figure when the method is executed in an actual processing procedure or a device.

Referring to fig. 5, an embodiment of the present application provides a file sharing system, where the file sharing system includes a sharing terminal, a shared terminal, and a presentation server. The sharing terminal may be understood as the demonstration terminal 101 in fig. 1 to fig. 4, the shared terminal may be understood as each viewing terminal (for example, the viewing terminal 201 or the viewing terminal 203) in fig. 1 to fig. 4, and the demonstration server may be understood as the demonstration server 302 in fig. 1 to fig. 4.

When the file shared by the sharing terminal is an online document locally stored by the sharing terminal, the address information of the online document can be obtained, and then the address information is sent to the demonstration server, so that the online document can be shared and demonstrated through a virtual demonstration room created by the demonstration server.

When the sharing terminal shares a locally stored conventional document (i.e., an offline document), as shown in fig. 5, the file sharing system in the embodiment of the present application may further include an online document server, which may be understood as the online document server 301 in fig. 1 to 4. Therefore, the sharing terminal can firstly send the local conventional document to the online document server, the online document server can convert the conventional document into the online document by calling the matched coding component, and then the address information of the successfully converted online document is returned to the sharing terminal. Further, the sharing terminal can send the address information of the online document to the presentation server, so that the online document can be shared and presented through the virtual presentation room created by the presentation server.

Specifically, the file sharing system in fig. 5 may be, for example, a system composed of all the devices included in any application scenario in fig. 1 to fig. 4, and will not be described one by one here.

It should be noted that the shared terminal in the file sharing system in the embodiment of the present application may include one (as shown in fig. 4) or multiple (as shown in fig. 1 to fig. 3), and one is schematically illustrated in fig. 5 as an example. And the sharing terminal and the shared terminal are only static roles corresponding to one moment, however, as the presenter changes in the file sharing system, the roles of the sharing terminal and the shared terminal also change, taking fig. 2 as an example, for example, at a certain moment, the presentation terminal 101 is the sharing terminal, and the viewer terminal 201, the viewer terminal 202 and the viewer terminal 203 are the shared terminals, and after the moment, for example, after the current presenter file is shared, the king manager can continue to share the file, then the viewer terminal 203 corresponding to the king manager can be changed to be the sharing terminal, at this moment, the role of the king manager becomes the presenter, and the presentation terminal 101 is set to be the shared terminal, that is, the role of the previous presenter corresponding to the presentation terminal 101 becomes the viewer, thereby realizing the role conversion.

Referring to an interaction diagram of the file sharing method in the embodiment of the application shown in fig. 6, in a specific implementation process, as shown in fig. 1, the requesting terminal and the sharing terminal may be the same device, or as shown in fig. 2 to fig. 4, the requesting terminal and the sharing terminal may also be different devices, in fig. 6, the requesting terminal and the sharing terminal are taken as two different devices for example, and the first terminal device is taken as the sharing terminal for example for explanation.

The following describes the technical solution in the embodiment of the present application with reference to fig. 6.

S601: the request terminal inputs a preset website to trigger generation of a file sharing request.

S602: and the request terminal sends a file sharing request to the demonstration server.

As described above, when a user wishes to share a file, the user may open a browser of the requesting terminal to input a predetermined website, so as to initiate a file sharing request for requesting to share the file to the presentation server.

Certainly, in a specific implementation process, other triggering manners may also be adopted to initiate a file sharing request to the presentation server, and the embodiment of the present application is not limited.

S603: and the presentation server creates a first virtual presentation room according to the file sharing request.

After the file sharing request sent by the request terminal is obtained, that is, it indicates that the user has a need to share the file, the presentation server may respond to the file sharing request to create a virtual presentation room, for example, a first virtual presentation room is created at this time, and file sharing may be performed in a manner of a virtual presentation room.

S604: the presentation server transmits room information of the first virtual presentation room to the requesting terminal.

After the first virtual presentation room is created, in order to facilitate that the terminal device can join the newly created first virtual presentation room, the presentation server may send room information of the first virtual presentation room to the requesting terminal that initiates the file sharing request, and in order to facilitate description, the embodiment of the present application refers to the room information of the first virtual presentation room as first room information, for example. Further, the requesting terminal may display the received first room information.

The first room information is information for identifying the first virtual presentation room, that is, the first room information may be understood as a room pass of the first virtual presentation room, and in a specific implementation, the first room information may be, for example, character information or other information, and the presentation manner of the first room information may be, for example, a character sequence or a two-dimensional code. For example, as shown in fig. 7, the first room information of the first virtual presentation room displayed by the requesting terminal is a character sequence of "723834342" and a two-dimensional code, the two-dimensional code in fig. 7 carries the character sequence of "723834342", and in fig. 7, for example, the first room information is referred to as "presentation code".

S605: the sharing terminal obtains the first room information from the requesting terminal.

The sharing terminal is a terminal used by a user for file presentation and sharing, so after the request terminal obtains first room information corresponding to the first virtual presentation room, the first room information may be sent to other terminal devices, for example, to the sharing terminal that wants to share the file, as understood in conjunction with fig. 2, for example, the first room information may be sent to the presentation terminal 101 in fig. 2, that is, the sharing terminal may obtain the first room information from the request terminal.

Similarly, the shared terminal (i.e., the viewing terminal) may also obtain the first room information from the requesting terminal in a similar manner, or after the sharing terminal obtains the first room information, the shared terminal may also obtain the first room information from the sharing terminal, and so on.

S606: and the sharing terminal scans the first room information and joins the first virtual demonstration room.

The terminal device obtaining the first room information may join the first virtual presentation room by scanning a code or directly inputting a character sequence, for example, both the sharing terminal and the shared terminal may join the first virtual presentation room in this way.

Taking the sharing terminal as an example, if the sharing terminal supports the code scanning operation, the user may join the first virtual demonstration room in a manner of scanning a code or inputting a character sequence by using the sharing terminal, and if the sharing terminal does not support the code scanning operation, the user may join the first virtual demonstration room in a manner of inputting a character sequence, as shown in fig. 8, the user just joins the first virtual demonstration room in a manner of inputting a character sequence.

S607: after determining a first file to be shared, the sharing terminal sends the first file to be shared to the online document server.

S608: and the online document server converts the first file to be shared into a first online document which can be cooperated by multiple persons.

The role of the first terminal device is positioned as a sharing terminal, which indicates that the user needs to share the file with the first terminal device, for example, the file that the user needs to share is called a first file to be shared.

If the first file to be shared is the online file, the first file can be directly shared with the presentation server. If the first file to be shared is not an online file, in order to realize online multi-user cooperation of the file, the sharing terminal can send the first file to be shared to the online file server so as to convert the first file to be shared into the online file through the online conversion capability of the online file server.

As described above, the online document server is a server that provides a background service for the online document application, so an online document client corresponding to the online document server may be installed in the sharing terminal, and the user sends the first file to be shared, which is not the online document, to the background online document server through the online document client, so that the online document server converts the first file to be shared into an online document that can be collaborated by multiple people, for example, the converted online document is referred to as a first online document.

The online document obtained through conversion by the online document server supports online multi-person cooperation, such as online editing, page turning, annotation and the like of multiple persons, and all operations of the online document by a presenter can be synchronized to each viewing terminal, so that file synchronization among conference users is realized, and file sharing fluency is enhanced.

The online document server in the embodiment of the application supports file conversion of multiple format types, for example, online conversion of document types, picture types and other types of files can be supported. Document files of document types such as PPT file, EXCEL, WORD, PDF, TXT, WPS, picture files of image types such as JPG, GIF, PSD, PNG, and so forth. The files corresponding to each format have a separate corresponding decoder (also called decoding component), encoder (also called encoding component) and player (also called playing component). Taking the first file to be shared as an example, after the file is uploaded, the online document server first determines the format of the first file to be shared, then calls a corresponding decoder to decode the file to obtain decoded data, and then transcodes the decoded data by using a matched transcoder to transcode the decoded data into Web page data capable of being presented in a Web page style, where the Web page data is document data corresponding to the converted first online document, for example, the document data corresponding to the first online document is called as first document data. For example, when the sharing terminal and the shared terminal need to display the first online document, the corresponding matched playing component may be downloaded from the online document server, and the first document data is played by the adapted playing component, that is, the first online document may be directly displayed by the Web page.

According to the file sharing method and device, online conversion of files of various formats and types is supported, the sharing range of the files can be expanded, sharing and display requirements of various types of files can be met through several online conversion capabilities of the online document server and various types of playing components correspondingly provided, and through Web page display, the playing terminal only needs to support a browser function, does not need to be installed with specified applications, and is low in software requirement capability of the playing terminal. And the Web page is a lightweight data display page, so that the consumed flow and the occupied bandwidth are less, and the file sharing and fluency and continuity can be ensured to a certain extent. In addition, the Web page presents the original file without distortion, so that the high fidelity of the file in the sharing process can be ensured.

S609: and the online document server sends the address information of the first online document to the sharing terminal.

The first address information of the first online document is, for example, a URL address, or may be a two-dimensional code carrying the URL address, or may be in other forms, which is not limited in this embodiment of the application. For convenience of description, in the embodiment of the present application, address information of a first online document is referred to as first address information, for example.

After receiving the first address information, the sharing terminal may invite the first address information to another user for viewing in a manner of short message, message sending in a social application, or friend sending, for example, when another user clicks a URL address corresponding to the first address information, the sharing terminal may view the first online document online in a browser on a Web page. Meanwhile, after the user clicks the URL address in the terminal device used by the user, the terminal device used by the user may be added to the first virtual demonstration room, that is, the terminal device may be added to the first virtual demonstration room by scanning the two-dimensional code corresponding to the first address information or clicking the URL address corresponding to the first address information.

S610: and the sharing terminal sends a demonstration request to the demonstration server.

Referring to fig. 9, a user selects an online slide to be presented, and then may send a local PPT file to an online document server to obtain a PPT online document, and join a first virtual presentation room by means of code scanning, further, the user clicks an "immediate presentation" button in an interface of a sharing terminal, and after detecting the operation, the sharing terminal generates a presentation request including first room information of the first virtual presentation room and first address information of the PPT online document, and sends the presentation request to the presentation server, so as to request the presentation server to present the first online document, that is, the PPT online document, in the first virtual presentation room.

S611: and the presentation server sets the file presentation authority of the first virtual presentation room to the sharing terminal.

In the embodiment of the application, the file demonstration permission is the highest permission in the virtual demonstration room, and comprises the highest watching permission and the highest editing permission, the terminal device with the file demonstration permission is obtained, and demonstration operations with various permissions, such as page turning operation, editing operation, deleting operation, modification operation and annotation operation performed by using a laser pen, amplification operation, reduction operation, cutting operation and the like, can be performed on the demonstrated online document, and the file operation information corresponding to various demonstration operations performed on the demonstrated online document based on the file demonstration permission can be synchronously shared to each terminal device in the corresponding virtual demonstration room, so that real-time synchronization of files between all viewers and the presenter is realized.

S612: the presentation server requests first document data corresponding to the first online document from the online document server through the first address information.

S613: the online document server sends the first document data to the presentation server.

S614: and the presentation server shares the obtained first document data to each terminal device in the first virtual presentation room.

After receiving a demonstration request of the sharing terminal, the demonstration server responds to the demonstration request, firstly, according to first room information in the demonstration request, the virtual demonstration room, needing file sharing, of the sharing terminal is determined to be the first virtual demonstration room, so that file demonstration permission of the first virtual demonstration room can be set to the sharing terminal, and certainly before the file demonstration permission is set, authentication can be carried out on the sharing terminal, and the permission is set only when the authentication is passed.

And the presentation server obtains first document data, such as the aforementioned Web page data, corresponding to the first online document from the online document server according to the first address information in the presentation request, and further shares the obtained first document data with each terminal device in the first virtual presentation room, for example, broadcasts the first document data to all terminal devices in the first virtual presentation room, or sends the first document data to each terminal device group in the first virtual presentation room in a multicast manner, so that the sharing terminals (presentation terminals) and the shared terminals (viewing terminals) in the first virtual presentation room can synchronously obtain the first document data in batch, so that all participants in the first virtual presentation room can view the first online document.

S615: and the shared terminal plays the first document data by using the playing component corresponding to the document type matching of the first online document.

Taking the shared terminal as an example, after the first document data is obtained, the play component matching the document type of the first online document may be downloaded from the online document server, for example, if the first document data is a PPT file type, the corresponding PPT play component may be downloaded, and if the first document data is an EXCEL file type, the corresponding EXCEL play component may be downloaded, so that it may be ensured that the first document data may be effectively played accurately without distortion, so as to ensure accuracy and effectiveness of file sharing.

In another possible implementation manner, since the presentation server is a center for managing the playing of the online document, the playing components corresponding to various file types may also be deployed in the presentation server, so that, for the online document shared by the virtual presentation room, the presentation server may provide the corresponding playing components to be invoked by the respective terminal devices in the virtual presentation room.

In a specific implementation process, the first address information may include information indicating a document type of the first online document, so that the file type of the first online document may be known after the first address information is obtained; or the document ID of the first online document may be included in the first address information, and the document type of the first online document may be searched for from the online document server by using the document ID; alternatively, data indicating the document type of the first online document may be included in the first document data, so that the document type of the first online document can be determined after the first document data is obtained. After determining the document type of the first online document in any way, the playing component of the corresponding type may be further determined to accurately play the first document data corresponding to the first online document.

In the embodiment of the application, after obtaining the first document data shared by the presentation server, the sharing terminal may also obtain the first document data locally or download a matched playing component from an online document server or the presentation server to correspondingly play the first document data, that is, the sharing terminal not only has a file presentation permission, but also has a viewing permission. Because the sharing terminal has a demonstration authority for the first online document, in the sharing process of the first online document, a presenter can perform corresponding demonstration operations, such as page turning operations, editing operations, annotation operations, deletion operations and the like, on the first online document, and then sends document update information corresponding to the first online document in the demonstration operations to the demonstration server, and the demonstration server synchronously shares the document update information to each terminal device in the first virtual demonstration room, so that each shared terminal can synchronously display files with the sharing terminal, and further, the files among all participants can be synchronously viewed, and the synchronism and the fluency of a conference are ensured.

In the embodiment of the application, the online documents are shared in batches by establishing the virtual demonstration room, so that the efficiency of sharing the documents can be improved, the document synchronization among participants can be realized as soon as possible, and the smoothness of document sharing is ensured. In addition, online documents supporting multi-user cooperation are shared, so that real-time operation and synchronous updating of the online documents by multiple users can be facilitated, and file synchronism is further improved.

In the embodiment of the present application, taking the conference scenario shown in fig. 3 as an example, the participants may include employees at different levels, for example, the participant shown in fig. 3 includes four levels, the first level is a general employee including employee a, employee B, employee C, and employee D, the second level is a middle manager including a king manager, the third level is a high-level manager including a director, and the fourth level is a presenter who may be considered to have the highest authority because the presenter is originally a presentation document. In order to enhance the diversity and applicability of file sharing, different viewing permission levels and editing permission levels can be set for participants at different levels, and in the specific implementation process, the setting mechanisms of the viewing permission levels and the editing permission levels can be the same or different. The viewing permission level is used for limiting the participants to see which contents in the shared file specifically, for example, the higher the viewing permission level is, the more comprehensive the contents can be seen, the editing permission level is used for limiting whether the participants can perform cooperative operation on the online document and which cooperative operation can be performed specifically when the cooperative operation can be performed, the viewing permission level and the editing permission level are controllable in the cloud, and therefore the reading and editing permissions of the collaborators can be set independently, and powerful document permission setting capacity can be provided by setting the viewing permission level and the editing permission level.

When submitting a first file to be shared to an online document server, a sharing terminal can mark some contents in the first file to be shared in advance or adopt other processing modes so that the online document server can effectively identify the contents with different marks, for example, as shown in fig. 10, one page in the first file to be shared is shown as an a diagram in fig. 10, which is original page data, when a presenter wants to share the page, the presenter wants to hide two parts of text contents, namely two monthly signposts 66, for a management leader, only hide the two parts of text contents, namely "design one monthly signpost 39, design two monthly signposts 66", and for the presenter himself, all the text contents need to be visible. Then the presenter can convert the page into three corresponding online data through the marks of the red circle and the blue rectangle frame when the online document server decodes the page of data, namely, as shown in a diagram a, a diagram b and a diagram c in fig. 10, and accordingly, three corresponding first document data can be obtained, and three first address information corresponding to the three first document data can be seen, and the content of the first online document corresponding to each address information is different.

In addition, besides the above-mentioned page content can be hidden according to users with different permission levels, some operation controls of the page can also be properly hidden, for example, fig. 10 a includes 5 operation controls of "participant list", "audio and video call", "view presentation list", "laser pen", "quit play", and the processed b diagram includes only 3 operation controls of "participant list", "audio and video call", "quit play", so that a user viewing the page shown in the b diagram cannot view the presentation list, cannot use the laser pen to perform operations such as online annotation or modification, and thus, partial collaboration permission of these collaborators is weakened considerably.

The sharing terminal can report all the three pieces of first address information to the presentation server, and further, the presentation server can obtain three pieces of first document data according to the three pieces of first address information. When the presentation server shares the first document data with the terminal devices in the first virtual presentation room, the presentation server may first determine the viewing permission levels of the terminal devices, divide the terminal devices having the same viewing permission level into one group, then determine one or more first document data matched with the viewing permission level of each group of terminal devices from the three first document data, and then share all the terminal devices in the group with the one or more document data corresponding to the viewing permission level of each group of terminal devices. If the viewing permission level of a group of terminal devices corresponds to one type of first document data, all terminal devices in the group play the same type of first document data, and if the viewing permission level of a group of terminal devices corresponds to multiple types of first document data, all terminal devices in the group may play the same type of first document data or may also play different types of first document data.

Continuing with the above example, for example, the first document data corresponding to the diagram a in fig. 10 is shared with the presenter and the director in fig. 3, the first document data corresponding to the diagram b in fig. 10 is shared with the employees a-D in fig. 3, and the first document data corresponding to the diagram c in fig. 10 is shared with the king manager in fig. 3, so that participants with different viewing permission levels can view slightly different page contents, because some contents in the file are only specific to some participants during the meeting process, contents which have no meaning or cannot be disclosed and need to be kept secret for some participants can be pre-hidden and filtered in the manner in the embodiment of the present application, so that each participant can obtain contents matching with its own permission level, the effectiveness of file sharing is improved, and the amount of shared data can also be reduced.

For the editing permission level mentioned above, taking the second terminal device in the first virtual demonstration room as an example, if it is monitored that the second terminal device performs an editing operation on the first online document, it may be determined whether the second terminal device has an editing permission, when the second terminal device has the editing permission, the editing operation is responded to obtain document update information of the first online document, and the document update information is determined to be synchronized to all the terminal devices or some terminal devices in the first virtual demonstration room according to the editing permission level, for example, the editing permission level is the highest, the document update information may be synchronized to each terminal device, for example, the editing permission level is general, the document update information may be synchronized to some terminal devices having the same viewing permission level or the same editing permission level as the second terminal device, for example, the editing permission level is the lowest, the document update information may be synchronized only to the second terminal device itself, in this way, the second terminal device itself may display a page change caused by the editing operation, and a user of the second terminal device may view this page change, but may not visually affect other terminal devices. When it is determined that the second terminal device does not have the editing right, the response to the editing operation may be prohibited, and at this time, the display page of each terminal device (including the second terminal device) does not change at all, so as to avoid the influence of the operation of the second terminal device on other participants as much as possible.

In a specific implementation process, the viewing permission levels of the viewers may be set in the sharing terminal by the presenter, for example, as shown in fig. 11, after the presenter clicks the "participant list" displayed in the sharing terminal, all participants in the first virtual presentation room may be displayed in a small window, as illustrated by the lower right diagram in fig. 11, in this case, the first virtual presentation room includes 5 participants, where the participant with the nickname "better tomorrow" is the presenter, and the other 4 participants are the viewers, and each viewer is followed by a five-pointed star marked, where the number of five-pointed stars indicates the high or low viewing permission level, the more five-pointed stars indicate the high viewing permission level, the highest viewing permission levels of "leaf guess" and "Tony" may be seen therein, as understood in conjunction with fig. 3, and "leaf guess" corresponds to, for example, the conquer in fig. 3, "tokyo" corresponds to, for example, and the manager of "Tony" in fig. 3, and thus, the guess level is higher. Further, the presenter may adjust the viewing permission level of each viewer, which will not be described in detail herein. Similarly, the viewing and setting of the editing permission level can also be handled in a similar manner, and will not be described repeatedly here.

During presentation of the first online document through the first virtual presentation room, other users may also add other online documents to be presented to the presentation list (or referred to as a presentation queue) to continue the presentation after the first online document is presented. For example, as shown in the upper diagram in fig. 12, during the presentation of the first online document, the user clicks the operation control of the "playlist" displayed on the display interface of the third terminal device in the first virtual presentation room, and then triggers the display of the playlist shown in the lower diagram in fig. 12, it is seen that there are 4 documents already added in the playlist at this time, further, the user may click the operation control of "add display file", then select one document from the third terminal device, convert the first file to be shared into the first online document, and add the first file to the online document, and then add the first file to the playlist. That is, the presentation server obtains a document adding request (for example, the aforementioned operation of clicking "add display file" and the operation of selecting a document) of the third terminal device, for example, the document adding request includes address information of the second online document, for example, the address information of the second online document is referred to as second address information, and the presentation server may respond to the document adding request and add the second online document to the presentation queue corresponding to the first virtual presentation room for subsequent sharing presentation.

For the second online document added to the presentation queue in the first virtual presentation room, the following two ways may be specifically adopted for presentation, which are respectively described below.

First demonstration mode

After the first online document is presented, the presentation server switches the file presentation authority of the first virtual presentation room from the first terminal device to the third terminal device, that is, the third terminal device continues to perform file presentation in the first virtual presentation room, and obtains document data (for example, referred to as second document data) corresponding to the second online document from the online document server according to the second address information, and then shares the second document data to each terminal device in the first virtual presentation room, so as to implement online sharing and presentation of the second online document.

That is, in the first presentation mode, the second online document is continuously presented in the first virtual presentation room, so that a plurality of online documents can be continuously presented in one virtual presentation room, and since participants included in one virtual presentation room generally do not change greatly, a scene in which the first online document and the second online document have the same audience is suitable, so that continuity in file switching and sharing can be ensured.

Second demonstration mode

The presentation server may further create a second virtual presentation room when the room switching trigger condition is met, and then share the second online document through the second virtual presentation room, that is, although the second online document is added to the presentation queue of the first virtual presentation room, the rooms may also be switched for presentation. In this case, the presentation server may set, for the third terminal device, a right to present the document in the second virtual presentation room, and obtain, according to the second address information, second document data corresponding to the second online document from the online document server, and broadcast the second document data to each terminal device in the second virtual presentation room, so as to implement online sharing presentation of the second online document.

For example, when the audience volumes of the second online document and the first online document are greatly different, if the presentation is continued in the first virtual presentation room, the second online document may be meaningless for most of the audiences, which wastes time of the users. In view of this, in the embodiment of the present application, the file can be continuously shared by switching rooms.

Moreover, after the second virtual demonstration room is newly created, the demonstration server may broadcast the second room information of the second virtual demonstration room to each terminal device in the first virtual demonstration room, and each terminal device may display the room information (i.e., a new demonstration code) of the new virtual demonstration room on the current page, for example, the second room information corresponding to the second virtual demonstration room shown in the lower right corner of the upper diagram and the lower diagram in fig. 12, so that a user corresponding to the terminal device in the first virtual demonstration room may select whether to join the second virtual demonstration room according to their actual viewing requirements, and thus it is possible to ensure that the users joining the second virtual demonstration room are all users who really wish to view the second online document, so that the file is more targeted and more effective, and the user experience of the user can be increased. In addition, other terminal devices which are not in the first virtual demonstration room can also be added into the second virtual demonstration room by scanning the second room information, so that the terminal devices in the second virtual demonstration room are updated on the basis of the terminal devices included in the first virtual demonstration room, and the effective sharing requirement of the second online document is met.

In a specific implementation process, the foregoing room switching trigger condition refers to a condition that a virtual presentation room can be switched, for example, a second virtual presentation room can be created again when a first online document starts presentation; alternatively, the second virtual presentation room may be re-created when the presentation duration of the first online document reaches a predetermined duration (e.g., 3 minutes); alternatively, the second virtual presentation room may be re-created when the remaining presentation pages of the first online document reach a predetermined number, e.g., 10 pages remaining for a PPT file; or, when the content of the first online document belongs to the content of the predetermined domain (e.g., science and technology or sports), and reaches the first predetermined time (e.g., 4 th minute after the start of the presentation) after the first online document starts the presentation; alternatively, the document type of the first online document belongs to a predetermined document type (e.g., EXCEL or PPT), and a second predetermined time after the first online document starts presentation (e.g., 4 th or 5 th minute after the start of presentation) is reached.
