In the description of the present invention, it is to be understood that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
FIG. 1 is a flowchart of a document processing method according to an embodiment of the present invention. As shown in fig. 1, the method for processing a document according to an embodiment of the present invention includes:
s1: and after receiving an access request of a browser of a requesting user to the target file, acquiring the authority information of the requesting user.
Illustratively, the background server configures a user for logging in the browser for each user of the enterprise a, sets corresponding authority for each user, and requests to store the authority information of each user. For example, the users of enterprise a are divided into 4 permission levels, which are permission level a, permission level B, permission level C and permission level D respectively in the order from top to bottom. It should be noted that the division of employees of a business into four levels is only an exemplary illustration, and those skilled in the art can set a plurality of authority levels. In addition, those skilled in the art can set different department levels for employees in different departments of the enterprise, for example, set authority level X for department X1Authority level X2And a privilege level X3(ii) a Setting authority level Y for department Y1And a privilege level Y2。
After the user of the enterprise A logs in the browser by using the user name of the user, the background server can obtain the user name, the login time and other information of the user, and the authority information of the user can be obtained through the user name. If a user (hereinafter referred to as a requesting user) requests access to a file (hereinafter referred to as a target file) on a browser.
And after receiving an access request of a browser of a requesting user to the target file, the background server acquires the authority information of the requesting user.
S2: and judging whether the requesting user has the authority to access the target file or not according to the authority information of the requesting user.
In one example of the present invention, the requesting user's right is the privilege level B. And if the access level of the target file is the authority level C (the authority level B is higher than the authority level C), judging that the requesting user has the authority for accessing the target file.
In another example of the present invention, if the requesting user's right is at level B of authority. And if the access level of the target file is the authority level A (the authority level B is lower than the authority level A), judging that the requesting user has the authority for accessing the target file.
S3: and if the requesting user has the right to access the target file, caching the target file through the document server, and displaying the target file on a browser of the requesting user.
Specifically, the working relation among the background server, the client browser and the document server is established in advance, when the background server judges that the requesting user has the right to access the target file, the document server caches the target file, and then the requesting user can access the target file through the browser.
In an embodiment of the present invention, after determining whether the requesting user has the right to access the target file, the method further includes: and if the requesting user does not have the authority to access the target file, forbidding the requesting user to access the target file, and generating and storing the unauthorized access information.
In an embodiment of the present invention, after obtaining the authority information of the requesting user, the method further includes: when the requesting user has the modification right to the target file, allowing the requesting user to modify the target file; when a request for modifying the target file by a requesting user is received, the modified target file is cached through the document server, and the modified target file is displayed through a browser of the requesting user.
In one example of the invention, the requesting user's right is the privilege level A. The access level of the target file is an authority level B, the modification level of the target file is A (the authority level B is lower than the authority level A), and after the background server receives an access request of a requesting user to the target file, the background server can grant the authority of the requesting user to modify the target file. When a user is requested to modify a target file, the modification information is cached by the document server, and the modified and modified target file is displayed through a browser of the user.
In another example of the present invention, the requesting user's right is the level of authority B. The access level of the target file is authority level B, the modification level of the target file is A (the authority level B is lower than the authority level A), and at the moment, the user is statically requested to download the target file.
In an embodiment of the present invention, after obtaining the authority information of the requesting user, the method further includes: when the requesting user has the downloading right to the target file, allowing the requesting user to download the target file; when receiving a request for downloading the target file from a requesting user, the document server provides the downloading resource.
Illustratively, the requesting user's permission is permission level A. The access level of the target file is authority level B, the downloading level of the target file is B (the authority level B is lower than the authority level A), and after the background server receives the access request of the requesting user to the target file, the authority of the requesting user for downloading the target file is granted. When the user is requested to download the target file, the document server provides the download resource.
According to the document processing method provided by the embodiment of the invention, after the permission verification is passed, the document server caches the file accessed by the user through the browser, local cache of the requesting user is not occupied, meanwhile, document information can be effectively prevented from being leaked, and the security of the document information is improved.
FIG. 2 is a block diagram of a document processing apparatus according to an embodiment of the present invention. As shown in fig. 2, the apparatus for processing a document according to an embodiment of the present invention includes: document server 100 and backend server 200.
Wherein the document server 100 is used for caching files. The background server 200 is configured to, after receiving an access request of a browser of a requesting user for a target file, acquire permission information of the requesting user, and determine whether the requesting user has permission to access the target file according to the permission information of the requesting user; if the requesting user has the right to access the target file, the target file is cached by the document server 100 and displayed in the requesting user's browser.
In an embodiment of the present invention, the backend server 200 is further configured to allow the requesting user to modify the target file when the requesting user has a modification right for the target file, and when receiving a modification request for the target file from the requesting user, cache the modified target file through the document server 100, and display the modified target file through a browser of the requesting user.
In one embodiment of the present invention, the backend server 200 is further configured to allow the requesting user to download the target file when the requesting user has the right to download the target file, and to provide the download resource by the document server 100 when receiving a download request of the requesting user for the target file.
