Problems solved by technology

However, there are also defects such as single function and inability to transfer files
[0005] Most of the existing technologies use dedicated client software combined with a modified desktop protocol to achieve file transfer, which is locked by manufacturers with client software, and some require dedicated desktop protocols, which do not support bidirectional transmission and other restrictions
This method has defects such as cumbersome installation, heavy framework, and high resource utilization

Abstract

The invention discloses a method for realizing drag-and-drop transmission of files in VNC by using a browser plug-in. Fetch the content of the file; encapsulate the data of the file content according to the extended RFB protocol format and realize the two-way transmission of data through the WebSocket connection between the browser and the VNC proxy service, that is, the drag-and-drop transmission of the host file to the virtual machine, and the virtual machine file Drag and drop transfer to host. The present invention conveniently and effectively solves the problem of two-way transmission of files between the host and the virtual machine, making VNC more convenient to use and richer in functions; it not only has the cost advantage of cloud computing but also takes into account the convenience of the virtualization software client. The functions and experience of cloud computing and virtualized control panels have been greatly improved. The invention also provides a corresponding device for realizing drag-and-drop transmission of files in VNC by using a browser plug-in.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and more specifically relates to a method and a device for realizing drag-and-drop transmission of files in VNC by using a browser plug-in. Background technique [0002] Virtual Network Console (VNC for short) is a remote control tool software. The Remote Frame Buffer (RFB for short) protocol is used for transmission, which is widely used in cloud computing and virtualization scenarios. [0003] Traditional virtualization software such as VMware, VirtualBox, etc. can realize two-way file transfer between the host and virtual machine by installing Tools (enhanced tools) in the virtual machine combined with special client software, and the file transfer is very convenient. [0004] noVNC is an open source VNC client implemented in HTML5, which can be accessed through a browser. Because of its light weight and convenience, it is widely used in the control panels of major cloud computing an...
