Abstract
The invention discloses a method for obtaining a download file resource list. The method comprises the following steps: A, an user terminal obtains an attribute information of a download file from a download server according to a download address of the download file; B, the user terminal sends the obtained attribute information to a resource server; C, when the resource server confirms that the attribute information of the download file is saved, the download resource list of the download file corresponding to the attribute information of the download file is obtained by utilizing the corresponding relationship; D, the resource server sends the download resource list to the user terminal. The invention also discloses a system for obtaining the download file resource list. The invention solves the problems of the prior art that the resource server is likely unable to find the download resource list and further the download resource is wasted when finding the download resource list corresponding to the file identification through a file identification.
Description
Technical field
The present invention relates to communication technical field, in particular, is a kind of method and system of obtaining resource listing of download file.
Background technology
Along with the continuous development of technique of internet, the application of internet in people's daily life is also increasingly extensive, utilizes the internet to realize that resource-sharing also is widely used, and wherein user terminal is exactly a kind of mode that realizes resource-sharing from the internet file in download.User terminal can pass through technology realizations such as multi-source download technology (P2SP), HTTP(Hypertext Transport Protocol) from the internet file in download at present.P2SP effectively combines the mirror image resources and the user terminal of server, server to user terminal (P2P) downloaded resources, on the speed of stability of downloading and download, all be enhanced to server (P2S) download than traditional P2P download or user terminal.HTTP can send to any a plurality of user terminal with the content that is arranged in network (Web) server of all parts of the world.By above technology, user terminal can be realized stable and download fast.Simultaneously, user terminal need use URL(uniform resource locator) (URL) to realize the download of file, the URL of file in download is called download address, all download address of this file in download are kept in the Resources list by Resource Server, if user terminal can obtain more download address, then can improve the success rate that file is downloaded, user terminal can send to Resource Server with the download address of file, obtains more download address by Resource Server.
Referring to shown in Figure 1, the user terminal step of obtaining resource listing of download file comprises in the prior art:
Step 11, user terminal send to Resource Server with the download address of file.
Step 12, described Resource Server are converted to the download address of described file the file identification of this document, when determining self to preserve described file identification, the corresponding relation of file identification of this document that utilization sets in advance and the tabulation of this document downloaded resources obtains the downloaded resources tabulation of this document, and this downloaded resources tabulation is sent to user terminal.
Referring to shown in Figure 2, realize that in the prior art the system that user terminal obtains resource listing of download file comprises: user terminal 21, Resource Server 22.
Described user terminal 21 is used for the download address of file is sent to Resource Server 22;
Described Resource Server 22, be used for the download address of described file is converted to the file identification of this document, when determining self to preserve described file identification, the corresponding relation of file identification of this document that utilization sets in advance and the tabulation of this document downloaded resources obtains the downloaded resources tabulation of this document, and this downloaded resources tabulation is sent to user terminal 21.
In the prior art, server is preserved the corresponding relation of file identification and downloaded resources tabulation in advance, user terminal sends to Resource Server with the download address of file, Resource Server is converted to this download address the file identification of this document, when Resource Server determines to exist this document sign, utilize the corresponding relation of the downloaded resources tabulation of the file identification of this document and this document to obtain the downloaded resources tabulation of this document, and this downloaded resources tabulation is sent to user terminal.
In sum, in the prior art, because file may be stored on the different Download Server, the download address of this document that user terminal obtains is not necessarily identical, thereby after user terminal sends to Resource Server with the download address of this document, Resource Server also can there are differences according to the file identification of this document of the download address conversion of this document, cause Resource Server possibly can't correctly find the downloaded resources tabulation of this document of file identification correspondence of this document, cause the waste of downloaded resources.
