Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The embodiments described in the following examples do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In this case, the expression "at least one of the items" in the present disclosure means a case where three types of parallel expressions "any one of the items", "a combination of any plural ones of the items", and "the entirety of the items" are included. For example, "include at least one of a and B" includes the following three cases in parallel: (1) comprises A; (2) comprises B; (3) including a and B. For another example, "at least one of the first step and the second step is performed", which means that the following three cases are juxtaposed: (1) executing the step one; (2) executing the step two; (3) and executing the step one and the step two.
In daily life, various files, especially video and image files, are increasingly required to be transmitted between mobile phones and PCs. There are three main ways of transferring files between different devices:
1. an external data line is used. This is the oldest and most common way to transfer files between a cell phone and a PC. Its advantages are high reliability and high transmission speed. However, this method requires carrying the data line at any time, and is not convenient. In addition, the mode cannot be used when some PCs do not have corresponding interfaces, some PCs also need to be provided with drivers, and the mode is also not suitable for file transmission among mobile phones and has a limited application range.
2. By means of software. In the method, the local area network can be established by using the mobile phone hot spot, and then other devices needing to exchange files with the mobile phone can be added into the local area network to transmit the files to each other in the local area network. Files may also be transferred directly over a wide area network, such as through WeChat. However, since this method requires installation of special software and the mobile phone and PC that exchange files with each other require installation of software, most schemes only support the mobile phone side, and rarely support the mobile phone and various smart devices, and this method is not suitable if it is desired to transmit files temporarily. Some software also compresses video files, losing the clarity of the transmitted files. In addition, when files are transmitted using a wide area network, in addition to the requirement for installing software, the network speed is also limited, and the wide area network is not suitable for transmitting large files.
3. And accessing the wide area network server through the webpage to transmit the file. This solution, in addition to being limited by network speed, also presents a security problem, since the transfer of files on a web page over a wide area network requires the assurance of the recipient's identity, which impairs operational convenience if logged on, and presents a security problem if not logged on.
The exemplary embodiment of the present disclosure provides a new file transmission method, which only needs to access each device to the same lan and have a web browser supporting JavaScript or other programming language (as long as the programming language can implement establishing a web server), and can establish a lan web server using a web page, thereby conveniently implementing mutual file transmission. The two conditions are easy to meet, no additional equipment is needed, no software is needed to be installed, the software is transmitted immediately, and the method is convenient and quick, so that the method is easy to realize, and the method is particularly obvious between a mobile phone and a PC. And because the mode has no limitation on the type of the equipment, the mobile phone and any intelligent equipment (including the mobile phone) which can be networked can realize the transmission at any time, so the application range is wide. In addition, high-speed and safe file transmission can be achieved by using the local area network, the transmitted videos and pictures can be transmitted in an original state, the phenomenon that the files are compressed in the transmission process can be avoided, the limitation of the network speed of the wide area network is avoided, and the information safety can be guaranteed while the trouble of login is omitted.
Fig. 1 is a timing diagram illustrating a file transfer system according to an exemplary embodiment of the present disclosure.
Referring to fig. 1, the file transfer system includes a host machine and at least one secondary machine participating in the transfer, and further includes a remote server as an auxiliary device.
Firstly, a remote server needs to be deployed, and a first webpage (e.g. JavaScript webpage) with a web server function is deployed on the remote server, where the first webpage may have a short website for convenient use. The function of the first web page is to start the lan network server and monitor a specific port (e.g. 8888) after the loading is completed, and then display a two-dimensional code on the first web page, where the content of the two-dimensional code is server information of the lan network server established by the first web page, and may include the ip and port number of the lan, for example, it may be expressed as ip: port, for other devices to scan the code to access. When other devices scan codes, the local area network server is accessed through the specific port, a request for opening a webpage is sent to the local area network server, the local area network server monitors the request and returns a second webpage with a file transmission function, and the other devices can upload and download files by using the second webpage. In the process, the local area network server can monitor the time of the request sending and the time of the request sending success, and can judge whether the two parties successfully establish the network link or not through whether the request of code scanning of other equipment succeeds or not, and can estimate the network speed between the two parties through the other equipment requesting the second webpage to finish loading the second webpage, and better experience can be provided for users through the two parameters when the files are transmitted.
When the file is actually transmitted, any device needing to transmit the file is selected as a host, a website of a remote server is opened on the device, a first webpage with a network server function is loaded, and after the loading is completed, a two-dimensional code can be displayed to enable other devices to scan codes for access. And other equipment needing to transmit files is used as a secondary machine, the two-dimensional code displayed by the scanning host machine accesses a local area network server established on the host machine, and a second webpage is opened. The local area network server can specifically realize the instruction request, and when the loading of the second webpage is completed, the host and the auxiliary machine can mutually interact the file contents to be uploaded and downloaded in a request mode such as post and the like. As an example, files can be selected on the second webpage in a post mode and uploaded to a local area network server, file transmission to the host is completed, and breakpoint resuming can be supported. When the auxiliary computer needs to download the file, the file can be downloaded from the main computer by using a get method, and breakpoint continuous transmission can also be supported. As an example, a file may also be transmitted using WebRTC (Web Real-Time Communication) technology.
Optionally, the lan network server may be http (File Transfer Protocol), Ssh (Secure Shell Protocol), or SFtp (Secure File Transfer Protocol), which has higher universality.
Further, the user can select which files on the host allow the secondary to download.
Further, the second webpage of the auxiliary machine comes from the host machine and can carry the server information of the host machine. The second webpage also has the function of a network server, so that a local area network server on the auxiliary computer can be established, a two-dimensional code file is generated, and the local server information can be uploaded to the host computer after the loading is finished, so that the host computer and the auxiliary computer mutually have the server information of the other side. Then the second auxiliary machine can be added by any one device with code scanning, and the information is synchronized in the same way, so that the capability of mutually transmitting files with any device after one-time code scanning addition is realized.
For convenience of explanation, the file transfer method according to the exemplary embodiment of the present disclosure will be described below from the perspective of the first device and the second device, which access the same local area network, according to the access relationship. It is understood that the first device and the second device belong to a relative concept, and reflect an access relationship between the two devices, wherein the first device is used as a "server side" for establishing the lan network server and is accessed, and the second device is used as a "client side" for accessing the first device (specifically, for accessing the lan network server established by the first device). The main machine and the auxiliary machine are fixed concepts, the main machine is a device for accessing a remote server, and the auxiliary machine is a device for accessing a local area network server. When there is only one slave, the master is the first device and the slave is the second device. When a second auxiliary machine is present and the second auxiliary machine accesses the first auxiliary machine, the first auxiliary machine is the first device and the second auxiliary machine is the second device for the first auxiliary machine and the second auxiliary machine. In short, the primary computer can only serve as a first device of a "server side", and the secondary computer can also serve as a first device of a "server side" on the basis of a second device serving as a "client side"; accordingly, the first device may be a master or a slave, while the second device may only be a slave.
Fig. 2 is a flowchart illustrating a file transfer method applied to a first device according to an exemplary embodiment of the present disclosure.
Referring to fig. 2, in step 201, in case of loading a first web page, a first lan web server is established. When the first device is a host, the first webpage is a webpage loaded when accessing a remote server, and a request for accessing the first webpage can be sent by inputting a website in a browser, of course, the website can also be stored as a bookmark, and the request for accessing the first webpage can be sent by clicking the corresponding bookmark. When the first device is the secondary machine, the first webpage is a webpage (i.e. the second webpage in step 203) loaded when the secondary machine accesses the lan network server, and only when the secondary machine is used as the second device, the webpage assumes a "client" role, and at this time, the webpage may also assume a "server" role. It is understood that the first device is a first lan network server established by means of its own hardware, and the first device is the first lan network server in terms of hardware.
In step 202, first server information of the first local area network server is displayed on a first webpage for other devices to access the first local area network server. Specifically, the first server information includes a local area network ip and a port number of the first local area network server. Optionally, the first server information is displayed in text, for example, as ip: port, and the user may input a corresponding website in a web browser of another device against the text to request access. Optionally, the first server information is displayed in the form of a two-dimensional code, a user can scan the two-dimensional code by using other devices to realize code scanning access, and the two-dimensional code is used as an interactive medium between different devices, so that the trouble of manual input is avoided.
In step 203, in response to a request for the second device to access the first lan network server, the second device sends the web page data of the second web page to the second device, so that the second device can transmit the file with the first device through the second web page. When the second device sends out a corresponding access request by using the first server information, the first device can send webpage data of a second webpage with a file transmission function to the second device after receiving the request, and the second device uploads a file to the first device or downloads the file from the first device by means of the second webpage. Alternatively, a button for uploading the file may be provided on the second web page, the button being linked to the local storage of the second device, and the file may be uploaded to the first device in a post manner after the user of the second device selects the file to be uploaded. And a button for downloading the file can be provided on the second webpage, the button is linked to the local memory of the first equipment, and after the user of the second equipment selects the file to be downloaded, the file can be downloaded from the first equipment in a get mode. Files may also be transmitted using WebRTC technology.
Optionally, the file transfer method further includes: in response to an input to hide a file, the corresponding file is hidden in the second webpage. When the file is transmitted, the first device can select to hide at least part of the file from the second device so as to protect the information security of the second device. Specifically, the files of the first device may not be hidden by default, and the corresponding files may be hidden in the second webpage only when the user performs an input for hiding the files. As an example, a hide button or a select button is configured for each file at the first web page, and the input for hiding the file may be to toggle the hide button or not toggle the select button. As an example, the input for hiding a file may be a button that triggers batch management, checking the file to hide or to display in a list of files. As an example, the input for hiding the file may be a long press of the file (suitable for the case where the first device has a touch screen) or a cursor being moved to the file and a right mouse button being clicked (suitable for the case where the first device is configured with a mouse) to invoke a menu in which the hidden option is selected. It will be appreciated that because the first device is interacting with the second device via the first lan network server via the network request, the files exposed at the second device are not desired as long as the filtering is controlled within the first lan network server.
Accordingly, the first server information may further include information of files hidden by the first device or information of files allowed to be downloaded.
Optionally, the file transfer method further includes: and in the case that the loading of the second webpage is determined to be completed, outputting the access information of the second device at the first webpage. When the second webpage is loaded, the request of the second equipment for accessing the first local area network server can be determined to be successful, and the network link is established between the second equipment and the first local area network server. By outputting access information of the second device to the first LAN network server on the first webpage, such as displaying or voice broadcasting "XXX is accessed", the user can know the connection condition of the device conveniently. As an example, for convenience of use, the display layout of the first webpage may be adjusted at different stages, when no device is accessed, the first server information in the form of a two-dimensional code is displayed in a larger layout on the first webpage, after it is determined that the second device is successfully accessed, the access information of the second device is output first, and then the first webpage is updated, so that the transmittable file is displayed in a larger layout. At the moment, the two-dimension code can be reduced or hidden firstly, and a button for amplifying and displaying the two-dimension code is configured, so that the two-dimension code can be called at any time and is accessed to other equipment.
Optionally, the file transfer method further includes: determining the network speed according to the loading time consumption of the second webpage, and determining the transmission duration of the file to be transmitted according to the network speed; and outputting the transmission time length. The required transmission time can be estimated by estimating the network speed when the second webpage is loaded by the second equipment and combining the size of the file to be transmitted. By outputting the transmission time length, the reference transmission time length can be prompted for the user, the user can conveniently and reasonably select the file for transmission, the transmission load can be reduced, and unnecessary waiting of the user can be reduced.
In step 204, the second server information of the second lan network server established by the second device is displayed on the first webpage. The second server information is used for the first equipment and other equipment except the second equipment to access the second local area network server and to transmit files with the second equipment. The second device can also have the function of establishing a local area network server, and upload corresponding second server information to the first device after the establishment is completed, so that the first device and the second device can mutually own the information of the other side, and the information synchronization is realized. It is understood that the second device is a second lan network server established by means of its own hardware, and the second device is the second lan network server in terms of hardware. After the first device receives the second server information, the second server information is displayed on the first webpage, so that other devices can simultaneously acquire the first server information and the second server information through the first device, the first local area network server can be accessed, the second local area network server can be accessed, a device group is formed, the operation convenience is greatly improved, and the convenience is more obvious when more devices are arranged in the group.
Alternatively, the first server information and the second server information may be separately displayed, and the other device may select which lan network server to access specifically. The specific display mode refers to a display mode of the first server information, and is not described herein again.
Alternatively, only one two-dimensional code may be displayed, the content of the two-dimensional code includes the first server information and the second server information, and the other devices may access all the lan network servers. It can be understood that the device subsequently joining the group can also establish a local area network server and send the local area network server to the original device in the group, and the device in the group updates the two-dimensional code according to the server information of the newly joined device, so that other devices can simultaneously obtain information of a plurality of servers only by scanning the code once. The two-dimensional code is used as an interactive medium between different devices, so that the trouble of manual input is avoided, more information can be transmitted, and the operation convenience is improved.
Fig. 3 is a flowchart illustrating a file transfer method applied to a second device according to an exemplary embodiment of the present disclosure.
Referring to fig. 3, first server information of a first local area network server established by a first device is acquired in step 301. Optionally, when the first server information is displayed in a text form, the first server information manually input by the user is acquired; when the first server information is displayed in a two-dimensional code form, the first server information obtained by identifying the two-dimensional code is obtained. Specifically, the first server information includes a local area network ip and a port number of the first local area network server.
At step 302, a request to access a first LAN network server is sent. After the first server information is obtained, an access request can be sent to the first local area network server in the local area network according to the local area network ip and the port number.
In step 303, web page data of the second web page fed back by the first lan web server in response to the request is received, and the second web page is loaded based on the web page data of the second web page. After receiving the access request, the first local area network server can feed back webpage data of the second webpage to the second device, and after receiving the webpage data, the second device can load the second webpage to complete network link between the second device and the first device.
At step 304, a second LAN network server is established. Similar to the first webpage, the second webpage also has the function of establishing a local area network server, and after the second device and the first device successfully establish a network link, the second device can establish a second local area network server with the same function as the first local area network server by using the function of the second webpage, so that files can be conveniently transmitted among a plurality of devices.
In step 305, the first server information and the second server information of the second lan network server are displayed on the second webpage for other devices to access the first lan network server and/or the second lan network server. The first server information and the second server information are displayed on the second webpage, so that other equipment can simultaneously acquire the first server information and the second server information through the second equipment, and can access both the first local area network server and the second local area network server, so that an equipment group is formed, the convenience of operation is greatly improved, and the convenience is more obvious when more equipment are arranged in the group.
Alternatively, the first server information and the second server information may be separately displayed, and the other device may select which lan network server to access specifically. The specific display mode refers to a mode in which the first device displays the first server information, and is not described herein again.
