Problems solved by technology

[0003] At work, it is often necessary to transfer files between the client and the server. Due to network instability and other reasons, the transmission is often interrupted during the transmission process. At this time, it is necessary to retransmit or continue the transmission. Currently, the file is being transferred When retransmitting, a database or configuration file is used to record the length information of the uploaded or downloaded file, which is very complicated to implement and needs to be improved

Embodiment Construction

[0018] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments.

[0019] The present invention provides a file transfer method under the C / S framework, which can realize the file transfer between the sending end and the receiving end, including the following steps:

[0020] Step 1, the sending end provides the receiving end with the file name, the identification information of the file, the length of the file and the file saving path;

[0021] The identification information may be a message digest or a hash value of the file;

[0022] Step 2, the receiving end names the temporary file according to the file name and the identification information of the file;

[0023] Step 3, the receiving end calculates the length of the received temporary file, and then notifies the sending end of the temporary file length;

[0024] Step 4, the sending end continues to transfer files to the receiving end until the end of th...

Abstract

The invention discloses a file transmission method under a C / S framework. The file transmission method used for transmitting files between a transmitting end and a receiving end includes the steps of firstly, the transmitting end provides a file name, file identification information, a file length and a file save path for the receiving end; secondly, the receiving end names a temporary file according to the file name and the file identification information; thirdly, the receiving end calculates the length of the received temporary file and notifies the transmitting end of the temporary file length; fourthly, the transmitting end continues transmitting the file to the receiving end until the transmission is ended; fifthly, the receiving end calculates the identification information of the received temporary file, wherein the transmission is successful if the identification information obtained by the calculation is identical with the file name of the temporary file. By the file transmission method, the situation of file re-uploading after file retransmission or transmission interruption can be reduced, and file transmission efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of computer data storage, and in particular relates to a file transmission method under the C / S framework. Background technique [0002] With the popularization of office electronicization, in order to improve the work efficiency and information security of employees in enterprises (units), most enterprises (units) carry out certain management and control on the office files of employees, and it is inevitable that local terminal files need to be uploaded / Backup to the server, and download / restore from the server when needed. [0003] At work, it is often necessary to transfer files between the client and the server. Due to network instability and other reasons, the transmission is often interrupted during the transmission process. At this time, it is necessary to retransmit or continue the transmission. Currently, the file is being transferred When retransmitting, a database or configuration file is used t...
