Method for obtaining media data of cloud storage files and cloud storage server

Abstract

The invention discloses a method for acquiring media data of cloud storage files and a cloud storage server. The method comprises the following steps that: cloud application of an intelligent terminal sends a cloud file metadata request to the cloud storage server and receives returned metadata of the corresponding cloud files; and after the cloud application receives an instruction of acquiring media data of the selected files, if uniform resource locators (URLs) of media data in the metadata of the corresponding cloud files points to the cloud storage server, the cloud application sends a request for acquiring the media data to the cloud storage server according to the URLs of the media data of the selected files and acquires the media data. The request which is sent by the cloud application to the cloud storage server and is used for acquiring the media data is not required to carry Token, so that the cloud storage server is used for making the cloud application acquire the media data according to the received request for acquiring the media data; and therefore, the problem that Token is overdue because the cloud application directly sends the request for acquiring the media data to the cloud server is solved.

Description

technical field [0001] The invention relates to the technical field of video multimedia, in particular to a method for acquiring media data of a cloud storage file and a cloud storage server. Background technique [0002] Users can obtain cloud storage files (or cloud files) by installing and running cloud applications (also called cloud applications or cloud storage applications) on smart terminals. The smart terminals installed with cloud applications may include smart devices such as smart phones, smart TVs, tablet computers, and handheld computers. [0003] Cloud files are usually stored in the following ways: figure 1 As shown: the metadata of the cloud file is stored in the local cloud storage server, and the media data of the cloud file may be stored in the third-party cloud server. [0004] After the smart terminal runs the cloud application, the process of obtaining the media data of the cloud file, such as figure 1 shown, including the following steps: [0005]...

Problems solved by technology

[0013] However, in practical applications, Token has a certain validity period, and the validity period of Token is usually no more than ten minutes; The media data of the file corresponding to the picture; then, the cloud server will receive the media data acquisition request carrying the expired Token, and the expired Token will not pass the authentication, and will not return the media data to the smart terminal; thus causing the user to obtain the media data data failure

This makes the user's experience of using cloud applications to obtain media data not good: in fact, after the user displays multiple file thumbnails through the smart terminal, he may need to access and obtain the media data of multiple files; however, downloading these files sequentially It takes a certain amount of time for the media data of the previous files; then, it is likely that after the user obtains the media data of the first few files, he finds that he cannot obtain the media data of some subsequent files; if the user wants to obtain the media data of other files, then Having to resend the cloud file metadata request to the cloud storage server, that is, repeating the above steps of S201-S206, brings great inconvenience to the user

[0014] To sum up, in the prior art method for smart terminals to obtain media data of cloud files, there will be a phenomenon that the Token validity period expires and the media data of cloud files cannot be obtained, resulting in poor user experience
