File upload and download method, system and related equipment based on sftp protocol

Abstract

The invention discloses a file uploading and downloading methods based on an SFTP (Secure File Transfer Protocol), wherein the file uploading method comprises the following steps: a client reads preset parameters from a server, wherein the preset parameters comprise an uploading path, a server IP (Internet Protocol), ports, a user name and passwords; and the client sends a file to be uploaded to the server in accordance with the SFTP according to the file name of the file to be uploaded and the preset parameters. The file downloading method comprises the following steps: the client reads preset parameters from the server, wherein the preset parameters comprise a downloading path, the server IP, the ports, the user name and the passwords; and the client receives the file to be downloaded in accordance with the SFTP according to the file name of the file to be downloaded of the server and the preset parameters. Correspondingly, the invention also discloses the client and the server. In the invention, the file transmission is carried out according to the preset parameters by storing the preset parameters in advance and the catalog of a local disk does not need to be operated manually, thereby improving the safety and stability of the client and the server.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a file upload and download method, system and related equipment based on the SFTP protocol (Secure File Transfer Protocol, secure file transfer protocol).
