File transfer method and system

Abstract

The invention provides a file transfer method and system. The method includes S101, transmitting a file uploading request to a server, wherein the file uploading request comprises a file name and a file total length of a specified file; S102, obtaining a file unique identifier returned by the server for the file uploading request; and S103, identifying the specified file by employing the file unique identifier, uploading a plurality of slice file streams of the specified file by employing a plurality of sub-threads, and identifying the plurality of file slice streams by employing the file unique identifier, wherein the plurality of file slice streams are formed by segmentation of the specified file according to a specified slice size. According to the method and system, parallel processingis performed by employing multiple threads, the speed is fast, the uploading of an extra-large file is supported, a client and the server realize a slice processing mechanism in a combined manner, and the problem of uploading of the large file is solved.

Description

technical field [0001] The present invention relates to the field of computer technology, and more specifically, to a file transmission method and system. Background technique [0002] Currently, most enterprises use File Transfer Protocol (FTP) tools to upload large files. The File Transfer Protocol (FTP) was designed to be a cross-platform, simple and easy-to-implement protocol. The File Transfer Protocol (FTP) has a long history of evolution and is one of the most important applications on the Internet, but today it is in decline. [0003] The disadvantages of the File Transfer Protocol (FTP) that people criticize include: First, FTP configuration is relatively cumbersome. Second, the data transmission mode is unreasonable. It is unreasonable to blindly use the ASCII mode to transmit data without considering the content of the file itself. Third, the design of the working method is unreasonable. The most incredible thing about the file transfer protocol (FTP) is that t...

Problems solved by technology

[0003] The disadvantages of the File Transfer Protocol (FTP) include: First, the FTP configuration is cumbersome

Second, the data transmission mode is unreasonable, regardless of the content of the file itself, it is unreasonable to blindly use the ASCII mode to transmit data

Third, the design of the working method is unreasonable. The most incredible thing about the file transfer protocol (FTP) is that the client will listen to the server.

Fourth, the password security policy is not perfect. On the FTP client and server, data is transmitted in plain text. Anyone who has the ability to control the routing on the communication path can obtain your password and data through sniffing.

Of course, we can use SSL to encapsulate FTP, but FTP transmits data by establishing multiple links. Even if we protect the password security, it is difficult to protect the security of data transmission.

Fifth, the FTP protocol is inefficient

[0004] To sum up, while the File Transfer Protocol (FTP) was once prominent, it is now obsolete and is a protocol that is neither secure nor friendly nor efficient
