Exemplary method
Fig. 1 is a flowchart of a file access method according to an exemplary embodiment of the present invention. As shown in fig. 1, the file access method includes the steps of:
step S101: when uploading a file, detecting whether temporary uploading authorization corresponding to the file uploading service is effective, executing file uploading operation when the temporary uploading authorization is effective, and returning a file downloading identifier after the file uploading is successful.
Optionally, before detecting whether the temporary uploading authorization corresponding to the file uploading service is valid or not when uploading the file, the method includes: and acquiring temporary uploading authorization from the system when the file uploading service is requested each time, and caching temporary uploading authorization information.
Optionally, when uploading the file, detecting whether temporary uploading authorization corresponding to the file uploading service is valid includes: when uploading a file, the file uploading service reads temporary uploading authorized cache information; detecting whether temporary uploading authorization corresponding to the file uploading service is effective or not according to the cache information; when the temporary uploading authorization is invalid, the system regenerates the temporary uploading authorization and updates the cache information.
In the embodiment of the invention, temporary authorization is acquired first when the file uploading and downloading service is requested each time, and the system and the permission are cached. Specifically, taking uploading and downloading of the content of the seal as an example, when the management edits the text-rich information of the article and the video picture attachment of the uploading data through the background management page, the uploading method of the front-end call sdk needs to request the back-end service interface to acquire the temporary authorization of the uploading file to store the temporary authorization, the back-end service can read the temporary authorization cache information when processing the temporary authorization request, and if the temporary authorization cache is invalid or expired, the cache can be automatically regenerated and updated.
Further, the front end performs uploading file storage by calling sdk uploading function after obtaining temporary authorization, and the sdk uploading file is uploaded in a file stream form, and when encountering a large-volume file such as a high-definition video, the front end automatically cuts file fragment uploading, and the fragments are automatically combined after the fragment uploading is completed. And meanwhile, the transmission in various formats such as binary, base64 and the like is supported during the uploading of the pictures. And returning a file downloading identifier after successful uploading, and providing data support for subsequent creation of the intermediate jump link and downloading of the file.
Step S102: and creating an intermediate jump link according to the file downloading identification, and storing the rich text containing the intermediate jump link and the file into a database together.
In the embodiment of the invention, because the link acquired by downloading is a temporary link and cannot be used as a file permanent link record system, the generation of a fixed intermediate jump link is adopted. Specifically, an intermediate jump link may be created according to the file download identifier, where the intermediate jump link is in a fixed standard format for calling the back-end service Get request, and examples of the intermediate jump link include, but are not limited to: https:// www.xxx.com/GetUrlfileId = file download identifier. After the creation of the intermediate jump link is completed, the rich text (html code segment) containing the intermediate jump link is saved to the database along with the file to maintain updated file information.
Step S103: when downloading the file, the intermediate jump link is clicked to jump to the file downloading service interface, the file downloading service interface generates temporary downloading authorization, the temporary downloading link is obtained according to the temporary downloading authorization and the file downloading identifier corresponding to the intermediate jump link, and the file downloading operation is executed through the temporary downloading link.
In the embodiment of the invention, when the requirement of downloading the file exists, the file service interface can be jumped to by clicking the intermediate jump link. The file service interface generates temporary downloading authorization, acquires the temporary downloading link according to the temporary downloading authorization and the file downloading identifier of the intermediate jump link, and executes file downloading operation through the temporary downloading link.
Optionally, the method further comprises: the front end requests a back end service interface; the back-end service interface responds to the request, reads the file from the database and returns the file to the front-end; the front end displays the file in an html form, and jumps to an actual storage link through a middle jump link aiming at html file tags of pictures and audios and videos related to the file so as to realize preloading operation of the pictures and the audios and videos.
In the embodiment of the invention, for the display of the file information, the front end requests a back end service interface, and the back end service reads the file information from the database and returns the file information to the front end. The front-end page displays file information in an html form, and media html file tags such as pictures, audios and videos can automatically jump to an actual storage link through a middle jump link to realize picture preview and audio and video preloading.
In summary, the intermediate jump link is created according to the file downloading identifier, and the rich text containing the intermediate jump link and the file are stored in the database together, so that the platform requirement of timeliness of the file access link is met, uploading and downloading functions of operation and maintenance personnel on the file in demand planning are met, access of malicious requests to file services is effectively limited, file data leakage is effectively prevented, and user experience of a user in an operation process is consistent with that of common uploading and downloading operations. The technical problem that the temporary access link is invalid when the file content with the temporary access link is directly stored in the database is solved.
