Example 1

Fig. 1 is a flowchart of a document locking method provided in an embodiment of the present invention, where the embodiment is applicable to a document locking situation, and the method may be performed by a document locking device in the embodiment of the present invention, where the device may be implemented in a software and/or hardware manner, as shown in fig. 1, and the method specifically includes the following steps:

s110, sending an assertion request to the server so that the server can determine assertion according to the identification information of the multi-user online editor carried by the assertion request.

The assertion request carries identification information of a multi-user online editor deployed on the client. The multi-person online editor can be an Office multi-person online editor or other multi-person online editors, for example, a WPS multi-person online editing tool or a third party multi-person online editing tool. The assertion is a piece of structured and cryptographically protected information.

Specifically, the client sends an assertion request to the server, and the server determines assertion according to the identification information of the multi-user online editor carried by the assertion request. For example, the server stores in advance the assertion provided by the assertion provider and the identification information of the multi-person online editor corresponding to the assertion, the client sends an assertion request to the server, and the server queries to obtain the assertion corresponding to the identification information of the multi-person online editor according to the identification information of the multi-person online editor carried by the assertion request sent by the client.

And S120, receiving the assertion sent by the server, and sending the access token request and the assertion to the server so that the server generates the access token according to the access token request and the assertion.

Wherein the access token is issued by the server to the client indicating that the client has been granted the same rights as the resource owner. Also, the authorization code includes information included in the access token including an agent, a user, and an authorization scope.

Specifically, the access token acquisition procedure may be: the client redirects the resource owner to the server. Then, the resource owner authenticates to the server, the authentication is successful, and the server returns the authorization code to the client. The client sends the received authorization code to the server in exchange for the access token. The usage scenario of this mode is typically that the client runs on a Web server or on the user's computer, which is the most secure and flexible. Wherein the resource owner is a person accessing the resource under his control using the client software. In the analytical system the resource owners are users.

Specifically, the server determines the assertion according to the identification information of the multi-user online editor carried by the assertion request, the server sends the assertion to the client, the client receives the assertion sent by the server and sends the access token request and the assertion to the server, so that the server generates an access token according to the access token request and the assertion.

Note that the authorized license type of AnyShare newly supports the assert license type of oauth2.0, also called assert mode. The assert license type is the first official extended license type issued by the OAuth working group. Under this license type, the client will get an assertion, which is used to trade the authorization server for the access token. In embodiments of the present invention, the assertion may be some authenticated document, such as a coupon or license. So long as the trust authority ensures the authenticity of the claims, the contents of the document are trusted to be authentic. In the AnyShare system, the multiplayer online editor takes the assertion and requests the access token from the server.

S130, receiving an access token sent by a server, wherein the access token carries identification information and user information of the multi-user online editor.

Wherein the user information includes a user identification. And S140, sending a document locking request to the server according to the access token so that the server locks the document to be locked according to the document identification to be locked and the access token carried by the document locking request.

Specifically, a document locking request is sent to a server according to an access token, so that the mode of the server for locking the document to be locked according to the document to be locked identifier carried by the document locking request and the access token can be as follows: when a user enters the multi-person online editor, the client sends a document locking request to the server according to the access token, and the server determines the multi-person online editor as a locker of the document.

If the multi-user online editor is always in use by a user, the locker of the document is always the multi-user online editor. Therefore, other editing tools such as a Web client, a synchronous disk and the like cannot edit the document, and the influence on users in the multi-user online editor is avoided.

In the embodiment of the invention, the server is used for carrying out identity authentication on the resource owner and the client, so that the resource owner authorizes the client and issues the access token for the client.

Optionally, the method further comprises:

Sending a document editing request to a server according to an access token, so that the server generates feedback information according to a document identifier carried by the document editing request, the identifier information of the multi-user online editor and user information;

and receiving feedback information sent by the server, and editing the document corresponding to the document identification.

Specifically, the method for sending the document editing request to the server according to the access token, so that the server generates feedback information according to the document identifier carried by the document editing request, the identifier information of the multi-user online editor and the user information may be as follows: the method comprises the steps that a client sends a document editing request to a server according to an access token, after the server receives the document editing request, the server judges whether a document corresponding to the document identification is locked by other clients according to the document identification carried by the document editing request, identification information of a multi-user online editor and user information, and if the document is not locked by other clients, feedback information is generated according to the document identification carried by the document editing request, the identification information of the multi-user online editor and the user information.

Specifically, the method for receiving the feedback information sent by the server and editing the document corresponding to the document identifier may be: if the feedback information received by the client and sent by the server is readable and writable, editing the document corresponding to the document identifier.

Optionally, if the feedback information sent by the server is readable and unwritable, the client opens the document corresponding to the document identifier in a read-only manner. In one specific example, a multi-person online editor can only open in a read-only manner if a document has been initially locked by a Web client, a synchronization disk, etc.

Optionally, the method further comprises:

when all users exit the multi-user online editor, a document lock release instruction is sent to a server, so that the server releases the document to be released according to the identification information of the document to be released, which is carried by the document lock release instruction.

When a user enters the multi-person online editor, the client sends a document locking request to the server according to the access token, and the server determines the multi-person online editor as a locker of the document. If the multi-person online editor is always in use by a user, the locker of the document is always the multi-person online editor. Until all users have exited the multi-user online editor, the document lock is released and other editing tools cannot be used normally.

In one specific example, the Office multiplayer online editor uses an access token to send a file edit request to a server. The server can know that the user edits on the multi-person online editor by analyzing the access token, and further the server can generate a log file according to the user identification edited on the multi-person online editor.

According to the technical scheme, an assertion request is sent to a server, so that the server determines assertion according to identification information of a multi-user online editor carried by the assertion request; receiving an assertion sent by a server, and sending an access token request and the assertion to the server so that the server generates an access token according to the access token request and the assertion; receiving an access token sent by a server, wherein the access token carries identification information and user information of a multi-user online editor; according to the access token, a document locking request is sent to the server, so that the server locks the document to be locked according to the document identification to be locked and the access token carried by the document locking request, the problem that when other users enter the multi-user online editor for editing, the situation of failure in storage occurs and the multi-user online editor is not available is solved, and the effect that in the process that one or more users use the multi-user online editor, other editing tools cannot edit the document is achieved.

and releasing the document to be released according to the identification information of the document to be released carried by the document lock release instruction.

In one specific example, as shown in FIG. 3, when a user enters the Office multi-person online editor, a document lock request is sent to the server. Unlike the non-multi-person online editors of Web clients and synchronization disks, the server can enable the Office multi-person online editors to be edited as document lock holders. If Office multi-person online editor editing is always in use by a user, then the holder of the document lock is always the editor. Therefore, other editing tools such as a Web client and a synchronous disk can not edit files, and the influence on users in the Office multi-user online editor can not be caused. Until all users have exited the Office multi-person online editor, the document lock was released and other editing tools could not be used normally. Of course if the file has been initially locked by a Web client, a synchronization disk, etc., the Office multiplayer online editor can only open in a read-only manner.

The embodiment of the invention receives an assertion request sent by a client, wherein the assertion request carries identification information of a multi-user online editor; determining assertion according to the identification information of the multi-user online editor; receiving an access token request and assertion sent by a client, and generating an access token according to the access token request and assertion; the access token is sent to a client, wherein the access token carries identification information and user information of a multi-user online editor; the method comprises the steps of receiving a document locking request sent by a client, locking a document to be locked according to a document identifier to be locked and an access token carried by the document locking request, and solving the problem that when other users enter the multi-user online editor for editing, the multi-user online editor is not available due to the fact that the other users can only become a locker of the document, and the effect that in the process that one or more users use the multi-user online editor, other editing tools cannot edit the document is achieved.

Alternatively, in other embodiments, the processor 11 may be configured to perform the document locking method in any other suitable way (e.g., by means of firmware).

Various implementations of the systems and techniques described here above may be implemented in digital electronic circuitry, integrated circuit systems, field Programmable Gate Arrays (FPGAs), application Specific Integrated Circuits (ASICs), application Specific Standard Products (ASSPs), systems On Chip (SOCs), load programmable logic devices (CPLDs), computer hardware, firmware, software, and/or combinations thereof. These various embodiments may include: implemented in one or more computer programs, the one or more computer programs may be executed and/or interpreted on a programmable system including at least one programmable processor, which may be a special purpose or general-purpose programmable processor, that may receive data and instructions from, and transmit data and instructions to, a storage system, at least one input device, and at least one output device.

A computer program for carrying out methods of the present invention may be written in any combination of one or more programming languages. These computer programs may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus, such that the computer programs, when executed by the processor, cause the functions/acts specified in the flowchart and/or block diagram block or blocks to be implemented. The computer program may execute entirely on the machine, partly on the machine, as a stand-alone software package, partly on the machine and partly on a remote machine or entirely on the remote machine or server.

In the context of the present invention, a computer-readable storage medium may be a tangible medium that can contain, or store a computer program for use by or in connection with an instruction execution system, apparatus, or device. The computer readable storage medium may include, but is not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. Alternatively, the computer readable storage medium may be a machine readable signal medium. More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.

The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.

It should be appreciated that various forms of the flows shown above may be used to reorder, add, or delete steps. For example, the steps described in the present invention may be performed in parallel, sequentially, or in a different order, so long as the desired results of the technical solution of the present invention are achieved, and the present invention is not limited herein.

The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives are possible, depending on design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
