It will be understood by those skilled in the art that the present disclosure may be practiced without some of these specific details. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.

Fig. 1 illustrates a flowchart of an online document editing method according to an embodiment of the present disclosure, which may be applied to an online document editing apparatus, which may be a processing device such as a server.

In some possible implementations, the online document editing method may be implemented by a processor calling computer readable instructions stored in a memory.

As shown in fig. 1, the online document editing method includes:

in step S11, a first version document sent by the editing client and used for updating the online document is received;

in step S12, in a case where a second version document of the online document of a preview client has been opened, sending update information to the preview client;

in step S13, receiving second version information of the second version document sent by the preview client;

in step S14, generating updated content according to the second version information and the first version information of the first version document;

in step S15, the update content is sent to the preview client.

In a possible implementation manner, the online document is a document edited and viewed online by multiple terminals. Further, the online document may be text, hypertext, data table, image, multimedia, 3D model, etc., and the present disclosure does not specifically limit the specific type of online document. While specific embodiments of the present disclosure have been described herein with respect to online documents such as text for the purpose of better illustrating the present disclosure, it will be appreciated by those skilled in the art that the present disclosure may be practiced with respect to other online documents such as hypertext documents as well.

In one possible implementation, the online document may have one or more preview clients viewing the document content and one or more edit clients editing the document content. The present disclosure does not specifically limit the number of preview clients and edit clients. Further, multiple editing clients may edit and update online documents separately in a non-simultaneous manner. In a possible implementation mode, the authorities of different editing clients can be set, the editing clients with different authorities can only perform operation matched with the authority of the online document, and the editing clients without authorities or with insufficient authorities cannot perform operation crossing the authorities.

In one possible implementation manner, in step S11, an updated first version document sent by the editing client may be obtained. The update form may include active update of a user of the editing client, that is, the user actively saves the current change content, so that the online document is updated. In addition, when the editing client side edits the document, if the system is crashed without being stored in time, the modified content of the online document is damaged, and therefore, the updating form may also include automatic updating of the online document by the editing client side with a fixed time interval. Further, the automatic updating may include automatic saving of the online document after the mouse of the editing client leaves the editing segment, or may include automatic saving of the online document after the page of the online document of the editing client is turned over. The present disclosure does not specifically limit the update form of the acquired first version document.

In one possible implementation, in step S12, in the case that a second version document of the online document of a preview client is already opened, update information is sent to the preview client. Specifically, the update information is used to indicate that the online document of the preview client has an update. Further, when the preview client establishes a connection with the server, the preview client may actively pull the latest version of the online document from the server, and when the preview client opens the pulled online document, the preview client sends information to the server: when the corresponding online document of the editing client, namely the first version document, is updated, please send notification information to the preview client. Specifically, when the server side does not receive the information of the notification information sent by the preview client side to the server side, the server side does not need to send the update information to the preview client side.

In one possible implementation, the editing client and the server interact data by using a web push technology. Specifically, after the online document of the editing client is updated, the server sends the update information to the preview client through a web push technology. In a possible implementation manner, the preview client establishes a long connection with the server, or the preview client initiates a session at regular time by using a polling policy, so as to ensure real-time communication between the server and the preview client. Furthermore, a WebSocket protocol can be adopted to realize the active push of the online document of the server to the preview client when the online document changes. WebSocket realizes two-way communication based on a single TCP connection, and the protocol process is divided into a handshake phase and a data transmission phase. In the handshake phase, the HTTP request sent by the client is parsed into an Update request by the Web server. After the handshake is successful, the data transmission stage is entered, and the two parties carry out information interaction on the established TCP connection. Compared with other Web push technologies, the efficiency and stability of WebSocket transmission are high, and network delay can be reduced.

In a possible implementation manner, the server may update the second version document of the preview client by comparing differences between different versions of the online document stored by the preview client and the online document stored by the editing client. Specifically, the server side can manage different versions of the online document. Therefore, after receiving the update information, the preview client sends the second version information of the online document of the preview client to the server. Further, in step S13, the server receives the second version information of the second version document sent by the preview client, so as to continue the difference comparison between the second version document and the first version document.

In one possible implementation manner, in step S14, updated content may be generated according to the second version information and the first version information of the first version document. In a possible implementation manner, when the second version document of the online document is stored in the server, the online document corresponding to the first version information and the online document corresponding to the second version information may be directly compared to obtain the updated content. In a possible implementation manner, when the specific difference content of each version of the online document is stored in the server, all the difference content between the first version information and the second version information may be used as the update content. Further, the version information includes saving time of the online document, and all difference contents between the saving times corresponding to the first version information and the second version information may be used as the update content. The manner of obtaining the difference content will be described in detail later with reference to possible implementations of the present disclosure, and will not be described herein again.

Since the content of each update of the editing client occupies a small proportion of the whole online document, the updated content in one online document often has only a few lines or words in many cases. Thus, the updated content may be limited to the modified content and the specific location where the modified content is located. In one possible implementation, the location may be a paragraph where the modified content is located, and the modified content may be an update of the paragraph. In a possible implementation manner, the position may be a specific line of a paragraph where the modified content is located, and the modified content may be an update of a specific line of characters of the paragraph. In a possible implementation manner, the position may be a specific line and a specific column of a paragraph where the modified content is located, and the modified content may be an update of a certain/several characters of the specific line of the paragraph. The present disclosure does not specifically limit the update form. In the embodiment, the updated content only comprises the updated content and the specific position where the updated content is located, namely only the changed content, so that when the preview client is updated, the whole online document does not need to be transmitted, and only the updated content needs to be transmitted, thereby greatly reducing the requirement on the network environment.

In a possible implementation manner, in step S15, the obtained updated content is sent to the preview client, so that the preview client fuses the updated content with the existing second version document to obtain the same online document as the editing client.

In the embodiment of the disclosure, the server does not need to transmit all the first version document after updating the online document to the preview client, but generates the updated content including the modified content to be updated of the second version document and the position of the modified content on the server according to the first version document and the second version document of the preview client, and transmits the updated content to the preview client, and the preview client realizes the content synchronization of the online documents of the preview client and the editing client according to the updated content. The updating process reduces the document contents transmitted by the server and the preview client on one hand, and reduces the requirements on the network environment; on the other hand, the preview client only needs to update the place needing to be changed, and the updating efficiency is improved.

When the online document is updated by the editing client, the updated document may not change compared with the last saved document due to the automatic update of the editing client or the change of the original content after the modification by the editing personnel. In one possible implementation, the method further includes: and comparing the first version document with the latest version document stored at a server side to obtain the difference content of the first version document and the latest version document. Continuing the document editing operation under the condition that the difference content is not empty; and terminating the document editing operation under the condition that the difference content is empty. According to the embodiment of the disclosure, the first version document is compared with the latest version document stored at the server, and only the first version document with the obtained different content not being empty is compared to continue the subsequent online document editing operation, so that unnecessary operations are reduced.

Further, the generating the updated content according to the second version information and the first version information of the first version document includes: and determining the difference content between the online documents corresponding to the second version information and the first version information as the updated content. In the embodiment, the difference content between the first version document and the last version document updated by the editing client is stored each time, after the second version information of the online document of the preview client is obtained, the difference content between the first version information and the second version information of the online document of the editing client can be determined as the update content of the preview client, and according to the version information of the online document of the editing client and the preview client, the difference content between adjacent versions of the online document stored by the server is fully utilized to quickly determine the update content, so that the online document of the preview client is updated in real time.

In a possible implementation manner, a cache database may be established in the memory to store the difference content between different versions of the online document, so as to improve the reading speed of the difference content in the online document editing process. Further, Redis may be used as a cache database. The selection of the cache database is not particularly limited by the present disclosure.

When the editing client is updated frequently, the server stores a large number of online documents of different versions and different contents, and the storage space is occupied. In one possible implementation, the method further includes: updating the latest version document to the first version document; deleting documents of versions of the online document other than the latest version document. The embodiment stores the latest version document of the online document and can perform comparison operation with the first version document; the versions except the latest version of the online document are deleted, so that the storage of the online document and the related files thereof at the server side can be effectively reduced. Meanwhile, the online document of any version can be quickly restored through the online document of the latest version and the difference content of each version of the online document.

To further reduce the size of data transmitted between the preview client and the server, in a possible implementation, the method may further include: and compressing the updated content to generate compressed information. Correspondingly, the sending the update content to the preview client includes: and sending the compressed information to the preview client. In this embodiment, the server side sends the compressed update content to the preview client side, which can further reduce the size of the transfer data and reduce the requirement on the network environment. Furthermore, the compressed information may include a ciphertext that can be identified by the preview client, so that information leakage of the online document is avoided, and data security is improved.

Fig. 2 shows a flowchart of an online document presentation method according to an embodiment of the present disclosure, which may be applied to an online document presentation apparatus, which may be a terminal device, a server side or other processing device. One or more of the display devices may be provided, and the present disclosure is not limited thereto. The terminal device may be a User Equipment (UE), a mobile device, a User terminal, a cellular phone, a cordless phone, a Personal Digital Assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, or the like.

In some possible implementations, the online document presentation method may be implemented by a processor calling computer readable instructions stored in a memory.

As shown in fig. 2, the online document presentation method may include:

step S21, a second version document of the online document is displayed.

Step S22, receiving update information of the online document sent by the server, where the update information is used to indicate that the online document has an update.

Step S23, sending the second version information of the second version document to the server according to the update information.

Step S24, receiving the updated content sent by the server, where the updated content includes the modified content and the location of the modified content.

Step S25, updating the second version document according to the updated content.

And step S26, displaying the updated second version document.

The online document is a document that can be displayed at the preview client, and may specifically be a text, a hypertext, a data table, an image, multimedia, a 3D model, and the like. The online document can be edited by an editing client and displayed on a preview client. After the online document is edited and stored by the editing client, the edited online document can be synchronously viewed at the preview client.

Specifically, the second version document of the online document is displayed at the preview client in response to a user's open request for the second version document. When the online document of the editing client is updated, the preview client may receive the update information of the online document sent by the server. Specifically, the update information is used to indicate that the online document has an update. Further, after the second version document is opened, the preview client may send information to the server: and after the editing client updates the online document, the editing client sends update information to the preview client. And after receiving the information, the server side sends the updating information to the preview client side when receiving the updated first version file of the online document sent by the editing client side. After receiving the update information, the preview client sends the second version information of the opened second version document to the server so that the server can determine the update content of the second version document through the difference between different versions of the online document. In a possible implementation manner, the updated content includes the modified content and the position of the modified content, so that the preview client performs modification at the position of the second version document according to the modified content, that is, performs fusion of the modified content and the second version document, generates an updated second version document, displays the updated second version document, and synchronizes the content of the online documents of the preview client and the editing client.

In the embodiment of the disclosure, the specific position of the opened second version document is updated through the update content sent by the server, and in the process, the updated first version document of the editing client is not required to be completely transmitted to the preview client, but only the specific update content is sent, so that the content synchronization of the online documents of the preview client and the editing client is realized. The updating process reduces the document contents transmitted by the server and the preview client on one hand, and reduces the requirements on the network environment; on the other hand, the preview client only needs to update the place needing to be changed, and the updating efficiency is improved.

In order to further reduce the size of data transmitted between the preview client and the server, in a possible implementation manner, the server compresses the update content and sends the compressed update content to the preview client, where in this case, the updating the second version document according to the update content includes: and decompressing the compressed information to obtain updated content. In this embodiment, the server side sends the compressed update content to the preview client side, which can further reduce the size of the transfer data and reduce the requirement on the network environment. Further, the compressed information may include a ciphertext that can be identified by the preview client, so as to avoid information leakage of the online document, and improve data security.

Application scenario example 1

The embodiment of the disclosure provides an online document editing method, which is applied to editing and checking a multi-terminal online document.

In an application example of the present disclosure, online document editing may include the following processes:

firstly, the server receives a first version document of the updated online document sent by the editing client.

And secondly, under the condition that the second version document of the online document of the preview client is opened, the server side sends update information to the preview client to indicate that the online document of the preview client is updated.

And thirdly, after receiving the updating information, the preview client sends second version information of the second version document to the server.

And fourthly, after receiving the second version information sent by the preview client, the server generates updated content according to the second version information and the first version information of the first version document, wherein the updated content comprises the changed content of the first version document relative to the second version document and the position of the changed content.

And fifthly, the server side sends the updated content to the preview client side.

And sixthly, after the preview client receives the updated content, updating the second version document according to the updated content.

And seventhly, displaying the updated second version document by the preview client.

In the embodiment of the disclosure, the first version document after updating the online document is not required to be completely transmitted to the preview client, but the updated content including the modified content of the second version document needing to be updated and the position of the modified content is generated on the server side according to the first version document and the second version document of the preview client, and then the updated content is transmitted to the preview client, and the preview client realizes the content synchronization of the second version document and the first version document according to the updated content. The updating process reduces the document contents transmitted by the server and the preview client on one hand, and reduces the requirements on the network environment; on the other hand, the preview client only needs to update the place needing to be changed, and the updating efficiency is improved.

Application scenario example 2

In recent years, the online court trial has rapidly progressed, and the efficiency and the quality of the court work in China are improved. The court trial record is an important document with legal efficiency produced by court trial activities. In an online court trial scene, when a judge modifies a record file, the crowd is required to immediately check the latest recorded content of the judge.

The embodiment of the present disclosure provides an online document editing method, and fig. 3 is a network topology diagram of the online document editing method, as shown in fig. 3, this method may implement real-time synchronization of updated court trial notes of a judge client at the party client through interaction of the party client, the judge client and a server, and the online document editing process may be roughly divided into five steps.

Firstly, a server side receives a first version of record which is sent by a judge client side and updates a court trial record. Specifically, the update may be an active save update of the judge, or an automatic save update of the judge client to the record at predetermined time intervals.

And secondly, comparing the first version record with the stored latest version record by the server to obtain the difference content between the two versions, wherein the difference content is used for indicating the difference content and the specific position of the difference.

And thirdly, under the condition that the difference content is not empty and the court trial record of the client side of the party is opened, the server side sends update information to the client side of the party, wherein the update information is used for indicating the client side of the party that the court trial record exists and is updated.

And fourthly, the server receives the second storage time of the court trial record opened at the client of the party.

And fifthly, the server takes all the difference content between the first saving time and the second saving time as the updating content according to the second saving time and the first saving time of the first version record. The updated content is the content needing to be changed in the second version record displayed by the client of the party and the specific position of the changed content. Specifically, the specific position is a modification line of the paragraph to be modified.

And sixthly, compressing the updated content by the server and sending the compressed updated content to the client of the party. After receiving the compressed updated content, the client side of the client firstly decompresses the compressed updated content, and updates the second version record at the position of the second version record, so that the updated content and the second version record are fused.

In the embodiment of the disclosure, the server does not need to transmit all the first version records of the court trial records updated by the judge client to the party client, but generates the updated content including the modified content of the second version records to be updated and the position of the modified content according to the first version records and the second version records of the party client at the server, and transmits the updated content to the party client, and the party client realizes the synchronization of the court trial records of the party client and the light-emitting client according to the updated content. The updating process reduces the content of the records transmitted by the server and the client of the party on one hand, and reduces the requirement on the network environment; on the other hand, the client of the party only needs to update the place needing to be changed, and the updating efficiency is improved.

It should be noted that the online document editing method according to the embodiment of the present disclosure is not limited to the application of the online court trial in the process of editing the notes, and may be applied to any online editing task, which is not limited in the present disclosure.
