Embodiment Construction

[0048] In order to solve the technical problems raised in the background art, the applicant of the present application analyzed the existing virtual desktop-based terminal screenshot method.

[0049] In an existing virtual desktop-based terminal screenshot method, if the keyboard screenshot button is used after the program is redirected, the image obtained is completely black, and the actual image cannot be obtained. Taking the video player program as an example, when the video player program is redirected, the VM no longer decodes and plays the video stream, the VM player displays a black screen, and the VM sends the video stream to the terminal, which decodes the video stream , and superimpose the decoded image on the corresponding terminal display interface of the VM player; when the user triggers the screenshot command, the terminal receives the screenshot command and sends the screenshot command to the VM; since the VM player displays a black screen at this time As a resu...

Abstract

The invention discloses a terminal screenshot method and device based on a virtual desktop. The method comprises the steps that a screenshot instruction for a current display interface of a target program is received; if it is determined that the target program is redirected, the screenshot instruction is executed to obtain a first screenshot; the first screenshot is sent to a virtual machine VM through a pre-constructed screenshot communication channel; the virtual machine VM saves the first screenshot to the preset position, and directly searches the preset position for a first screenshot pasting instruction after a pasting instruction for the first screenshot sent to the terminal is received to achieve the terminal screenshot. After the target program is redirected, the terminal can still achieve the screenshot, and the potential hazards caused when the first screenshot is saved at a shared network are avoided.

Description

technical field [0001] The present application relates to the field of network technology, in particular to a method and device for taking screenshots of terminals based on virtual desktops. Background technique [0002] Virtual Desktop Infrastructure (VDI) replaces traditional hosts with virtual desktops, thereby concentrating scattered hosts in the data center to achieve centralized management. VDI hosts the desktop operating system originally running on the terminal device to the virtual machine (Virtual Machine, VM) in the server to run, and the terminal accesses it remotely through the network, and the terminal itself only needs to implement input and output and interface display functions to realize desktop Standardization and centralized management of the operating system. [0003] In VDI, terminals run terminal operating systems, VMs run desktop operating systems, and certain types of programs are redirected to terminal operating systems. After the program is redir...
