Embodiment Construction

[0025] In this embodiment, the file information corresponding to the file identifier of the binary file downloaded by the user is determined according to the established correspondence between the file identifier and the file information, so as to ensure that the user can determine whether the content of the downloaded file conforms to his own before downloading the file. need.

[0026] Wherein, the file identifier is used to identify the file, which may be a file name, a URL (Uniform Resource Locator) where the file is stored, or a content signature (Content Identity, CID), etc. Wherein, the content signature CID is obtained after calculating the content data of the binary file according to a preset algorithm. The preset algorithm can be any algorithm that processes the content data of different binary files to obtain different processing results. Low, algorithm within acceptable range.

[0027] The file information includes, but is not limited to, one or more of the following

Abstract

The invention relates to a network download technique, in particular to a method, a system and a device obtaining document information. The invention solves a problem of the prior art that a user is not able to obtain accurate information of the document to be downloaded before downloading which leads to in capability of guaranteeing the quality of downloaded document. The invention includes: a client-side-side obtains a document mark of a binary system document which is not completely downloaded; a server determines a corresponding document information of the document mark obtained by the client according to a corresponding relationship of the established document mark and the document information; the client displays the document information determined by the sever to the user. By adopting the invention, the user is able to be aware of the quality of the document before downloading, and situations that a re-downloading caused by bad quality of the downloaded document are reduced, and time and downloading bandwidth of the user are saved.
