Problems solved by technology

[0009] 1. When the Linux host cannot be connected to the Internet and the client cannot communicate with the Linux host, the file transfer between the Linux host and the client cannot be realized;
[0010] 2. The file transfer adopts ftp and other low-security technologies, and the security needs to be improved

Embodiment 1

[0104] According to a specific embodiment of the present invention, with reference to the attached Figure 4 , the file uploading method of the present invention comprises:

[0105] First upload the file to be uploaded to the web server, and the client generates a file upload command through the file drag or upload button on the web front-end interface. Segmentation, and then random arrangement, and then the web front end transmits the file upload command and the processed file data stream to the data interaction layer through the http protocol.

[0106] File segmentation and random arrangement based on the dynamic dictionary is to enhance the security of file transmission and prevent files from being directly cracked after being intercepted. After sealing and random arrangement based on the dynamic dictionary, the file data can only pass the rules agreed by both parties. Only then can the sequence be arranged and integrated, and the original file can be obtained, which great...

Embodiment 2

[0114] According to a specific embodiment of the present invention, with reference to the attached Figure 5 , the file download method of the present invention is: the client enters the absolute path of the file to be downloaded in the target host through a text box in the web front-end interface to generate a file download command, and the web front-end transmits the download command generated in the web front-end interface through the http protocol To the data interaction layer; the data interaction layer receives the data from the front end of the web and analyzes it to determine whether it is a file download event, and if it is, it will send information related to the file download event, such as the uuid of the Linux target host and the file to be downloaded in the target host The absolute path of the file is sent to the general file proxy transmission storage layer, and the general file proxy transmission storage layer is notified to trigger the download event; the gener...

Abstract

The invention provides a web ssh-based file transfer method and device, and relates to the technical field of file transfer. The method includes: a method for uploading files from a client to a target host through an upload button or dragging and dropping files on the web front-end interface, and a method for the client to download files from the target host through input in a text box on the web front-end interface, and by adding a general file agent to transfer and store Layer and data interaction layer for file data interaction, and the common file proxy transfer storage layer uses ssh to access the Linux target host to realize the file transfer between the client and the Linux target host. The present invention realizes the file transmission between the client and the Linux target host under the condition that the Linux target host cannot be connected to the Internet and the client cannot communicate with the Linux target host.

Description

technical field [0001] The invention relates to the technical field of file data transmission, in particular to a web ssh-based file transmission method and device. Background technique [0002] With the rapid development of the Internet, the copying and transfer of files is not limited to the local machine, and the file transfer between different machines in the Internet or LAN is becoming more and more common. Then, how to realize the file transmission between machines in the Internet, in the local area network, and between machines in the Internet and the machines in the local area network has become a problem that people pay more attention to. [0003] The SSH (Secure Shell) secure shell protocol is a security protocol based on the application layer developed by the Internet Engineering Task Force of the IETF (The Internet Engineering Task Force). SSH is a protocol that provides security for remote login sessions and other network services. It has more reliable security...
