[0053] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] Embodiment 1:

[0055] Refer to Figure 1 , Figure 1 which is a flowchart of an implementation of the document access control method in the embodiment of the present invention. The method may include the following steps:

[0056] S101: Parse the received document access request to obtain the access terminal identity information.

[0057] When the access terminal needs to access a document, it sends a document access request to the document access control system. The document access request contains the access terminal identity information. The document access control system receives the document access request and parses the received document access request to obtain the access terminal identity information.

[0058] S102: Traverse each source file that makes up the document to be accessed.

[0059] The document to be accessed is pre-divided into multiple source files. The document access control system traverses each source file that makes up the document to be accessed.

[0060] S103: Determine whether there is a source file role identifier or a source file content role identifier in each source file. If so, execute step S104; if not, do nothing.

[0061] By traversing each source file that makes up the document to be accessed, determine whether there is a source file role identifier or a source file content role identifier in each source file. If a source file contains a source file role identifier or a source file content role identifier, then step S104 is executed. If none of the source files contain a source file role identifier or a source file content role identifier, no processing is performed.

[0062] For example, first determine whether there is a source file role identifier, that is, determine whether there is a filtering rule in the source file. If so, use the existing source file role identifier as the basis for matching and judging with the access terminal identity information. If not, determine whether there is a source file content role identifier in the source file. If there is a source file content role identifier in the source file, use the source file content role identifier as the basis for matching and judging with the access terminal identity information.

[0063] S104: Match the existing source file role identifier and source file content role identifier with the access terminal identity information respectively.

[0064] When it is determined that a source file contains a source file role identifier or a source file content role identifier, match the existing source file role identifier and source file content role identifier with the access terminal identity information respectively.

[0065] S105: Return the target source file corresponding to the successfully matched source file role identifier and the target source file content corresponding to the successfully matched source file content role identifier to the access terminal.

[0066] By matching the existing source file role identifier and source file content role identifier with the access terminal identity information respectively, and returning the target source file corresponding to the successfully matched source file role identifier and the target source file content corresponding to the successfully matched source file content role identifier to the access terminal, unified authentication and authorization of the document are realized, reducing the manual input of the document compiler for repeated maintenance of public content, greatly improving the development experience and efficiency of the document compiler, and improving the document compilation efficiency.

[0067] The document access control method provided by the present invention parses the received document access request to obtain the access terminal identity information; traverses each source file constituting the document to be accessed; respectively determines whether there is a source file role identifier or a source file content role identifier in each source file; if so, respectively matches the existing source file role identifier and the source file content role identifier with the access terminal identity information; returns the target source file corresponding to the successfully matched source file role identifier and the target source file content corresponding to the successfully matched source file content role identifier to the access terminal. By obtaining the access terminal identity information, and pre-dividing the document to be accessed into multiple source files, setting role identifiers for the source files and the source files according to the permission rules, and obtaining the target source files and the target source file content within the scope of the access terminal identity information permission through the role matching method. There is no need to compile duplicate document content, which reduces the cost, improves the document compilation efficiency, and reduces the maintenance difficulty.

[0068] It should be noted that, based on the above-mentioned Embodiment 1, the embodiments of the present invention also provide corresponding improvement solutions. In the subsequent embodiments, the same steps or corresponding steps involved in the above-mentioned Embodiment 1 can be referred to each other, and the corresponding beneficial effects can also be referred to each other, and will not be repeated one by one in the following improvement embodiments.

[0069] Embodiment 2:

[0070] See Figure 2 , Figure 2 which is another implementation flowchart of the document access control method in the embodiments of the present invention. The method may include the following steps:

[0071] S201: Receive a document access request.

[0072] The document access control system receives the document access request sent by the access terminal.

[0073] S202: Determine whether the document access request is an access request sent after the access terminal logs in to the system. If so, execute step S203; if not, execute step S204.

[0074] The document access request may be to access the online document through the "Help" built in the system after the access terminal logs in to the system, or the access terminal may access the document through an external link. After receiving the document access request, determine whether the document access request is an access request sent after the access terminal logs in to the system. If so, execute step S203; if not, execute step S204.

[0075] S203: Obtain the identity authentication information when the access terminal logs in to the system, and use the identity authentication information as the access terminal identity information.

[0076] When it is determined that the document access request is an access request sent after the access terminal logs in to the system, obtain the identity authentication information when the access terminal logs in to the system, and use the identity authentication information as the access terminal identity information.

[0077] S204: Send an identity authentication instruction to the access terminal to obtain the access terminal identity information input by the access terminal.

[0078] When it is determined that the document access request is not an access request sent after the access terminal logs in to the system, send an identity authentication instruction to the access terminal. After receiving the identity authentication instruction, the access terminal inputs the access terminal identity information for access verification, so as to obtain the access terminal identity information.

[0079] S205: Traverse each source file that makes up the document to be accessed.

[0080] When traversing each source file that makes up the document to be accessed, the toolbar sidebar can be obtained according to the entry file index.html of the online document, and the toolbar content (defining the sidebar and the paths of each source file) can be read sequentially, and parsed and judged in sequence and parent-child level Whether the path defined by the label and its specified source file are the components of the sidebar and the document.

[0081] S206: Determine whether there is a source file role identifier or a source file content role identifier in each source file respectively. If so, execute step S207; if not, do nothing.

[0082] S207: Match the existing source file role identifier and source file content role identifier with the access terminal identity information respectively.

[0083] When matching the access terminal identity information with the existing source file role identifier and source file content role identifier, taking the cloud platform as an example, the user structure of the cloud platform is divided into two ends and four roles. However, since the management end is all in the administrator role, although there are differences, the differences are not too large. Therefore, the document is defined to apply the same set of documents at the management end.

[0084] roles represents the role object to which this filtering rule applies, and its values and meanings are as follows:

[0085] admin indicates that it applies to the management end and maps to systemadmin and domainadmin in the cloud platform.

[0086] vdcadmin indicates that it applies to the tenant end administrator and maps to vdcadmin in the cloud platform.

[0087] vdcuser indicates that it applies to the tenant end user and maps to vdcuser in the cloud platform.

[0088] S208: Read the target running environment information of the access terminal.

[0089] After matching the existing source file role identifier and source file content role identifier with the access terminal identity information respectively to obtain the target source file corresponding to the successfully matched source file role identifier and the target source file content corresponding to the successfully matched source file content role identifier, read the target running environment information of the access terminal.

[0090] S209: Determine whether the document to be accessed is compatible with the target running environment information. If so, execute step S210; if not, do nothing.

[0091] After reading the target running environment information of the access terminal, determine whether the document to be accessed is compatible with the target running environment information. If so, it means that the obtained target source files and target source file contents can be successfully displayed at the access terminal, and execute step S210; if not, it means that the obtained target source files and target source file contents cannot be successfully displayed at the access terminal, and do nothing.

[0092] For example, a flag file can be preset to indicate whether the target operating environment information of the document to be accessed matches the access terminal. For example, it can be represented by "isinclouded". When "isinclouded" is "y", it indicates a match, and the target source file or the content of the target source file can be presented to the access terminal for viewing. When "isinclouded" is "n", it indicates a mismatch, and the target source file or the content of the target source file cannot be presented to the access terminal for viewing.

[0093] S210: Assemble the obtained target source files and the content of each target source file to obtain a target online document.

[0094] After determining that the document to be accessed matches the target operating environment information, assemble the obtained target source files and the content of each target source file to obtain a target online document.

[0095] S211: Return the target online document to the access terminal.

[0096] After assembling the target online document, return the target online document to the access terminal. By obtaining the identity information of the access terminal and pre-dividing the document to be accessed into multiple source files, setting role identifiers for the source files and the source files according to the permission rules, and obtaining the target source files and the content of the target source files within the scope of the access terminal identity information permission through role matching. There is no need to compile duplicate document content, which reduces costs, improves the document compilation efficiency, and reduces the maintenance difficulty.
