File transmission processing method and related devices

Abstract

The embodiments of the invention disclose a file transmission processing method and related devices. The method provided by the embodiments of the invention comprises the following steps: determininga file to be transmitted; analyzing the file to obtain basic information and preview information of the file, wherein the basic information includes a feature value of the file; sending the preview information of the file to a server; and sending a transmission request of the file and the basic file information of the file to a receiver, wherein the transmission request of the file is used for indicating the receiver to receive the basic information so that the receiver obtains the preview information from the server through the feature value. The embodiments of the invention also provide a terminal and a server. According to the embodiments of the invention, the pressure for the server to analyze the file to be transmitted is greatly reduced, and file preview service can be provided for any file transmission scenarios, i.e., the method is suitable for both instant file transmission scenarios and non-instant file transmission scenarios, and the application scope is very wide.

Description

technical field [0001] The present invention relates to the communication field, in particular to a file transmission processing method and related equipment. Background technique [0002] File transfer is to transfer a file or a part of it from one computer system to another computer system, and it has become a common operation in work and life for users to transfer files through the network. Usually, the ways of transferring files include mail, Instant Messaging (Instant Messaging, abbreviation: IM) software, network disk, and the like. However, users also have some troubles when receiving transfer files. For example, downloading a large compressed file, and opening the file after downloading, it is found that the content is not what you need, which wastes a lot of time for the user. Some malicious users may also disguise executable files such as viruses or Trojan horses as pictures or documents, and induce users to download them to spread virus files. [0003] In order...

AI Technical Summary

Problems solved by technology

[0004] Among the above methods, the virus detection function provided by the mail has a certain lag, and whether it is the first method or the second method above, it all depends on the analysis of the transmitted file by the server. When a large number of users in the same time period When uploading files, the parsing pressure of the server will be relatively high, and the running speed of the server will be affected

And the server must have a complete file in order to parse the file information and provide file preview services. For point-to-point real-time file transfers, the server cannot provide file preview services
