For example, suppose that a user has two mobile zero terminals, the two zero terminals can log in to the mobile device cloud service platform to process corresponding pages, and at the same time, the user controls two desktop zero terminals. If the user wants to control the four devices at the same time, according to the prior art, the user needs to use the two mobile zero terminals to be connected to the mobile device cloud service platform respectively and use the two desktop device zero terminals to log in the desktop device cloud service platform, namely, the user needs to control the four devices at the same time, under the condition, the user needs to pay attention to the real-time response condition of the four devices at the same time, and the whole operation becomes busy and disorderly. However, according to the scheme disclosed herein, the user only needs to log in the mobile device cloud service platform and the desktop device cloud service platform through one desktop zero terminal respectively.
Specifically, the desktop zero terminal needs to send connection requests for four login accounts to the mobile device cloud service platform and the desktop device cloud service platform altogether, wherein two of the connection requests are for the mobile device cloud service platform, and the other two connection requests are for the desktop device cloud service platform. The cloud service platform receiving the connection requests can perform authentication and certification on the corresponding connection requests, if the authentication and certification are passed, different virtual machines are allocated to process the services of all login accounts, and desktop images of the four connections are returned to the desktop zero terminal. And the virtual machine for processing the equipment services in the cloud service platform collects corresponding desktop images according to a preset frequency and sends the collected desktop images to the desktop zero terminal.
In one embodiment, receiving a desktop image sent by a virtual machine corresponding to each connection request, and displaying the desktop image in a preset display area according to a virtual machine address corresponding to each connection request includes:
the zero terminal receives the desktop image sent by the virtual machine corresponding to each connection request, and marks each received desktop image according to the virtual machine address corresponding to each connection request;
and setting a corresponding display window for each desktop image after marking, and distributing each desktop image to the corresponding display window.
In this embodiment, the desktop zero terminal will continuously receive the desktop images sent by the four virtual machines, and for the desktop zero terminal, the following processing needs to be performed in the process of receiving the desktop images:
the desktop zero terminal distinguishes the source of the received image according to the address of the virtual machine of the sending end of the received desktop image; setting different display windows aiming at images from different virtual machines; and distributing the received desktop images to respective corresponding windows for display according to the virtual machine sources.
Optionally, as shown in fig. 2, the method further includes:
in one embodiment, as shown in fig. 3, determining the display window corresponding to the keystroke message comprises:
2021, acquiring all currently opened windows and a window stacking sequence;
in one embodiment, as shown in fig. 4, performing coordinate position conversion on the keyboard and mouse message according to a preset rule, and generating the keyboard and mouse message after the coordinate position conversion includes:
2041, calculating pixel points corresponding to the coordinate positions in the keyboard and mouse message on a desktop image sent by the corresponding virtual machine according to the virtual machine corresponding to the display window;
2042, determining the converted coordinate position according to the pixel point corresponding to the coordinate position in the keyboard and mouse message on the corresponding pixel point on the desktop image sent by the corresponding virtual machine;
And step 205, sending the keyboard and mouse information after the coordinate position conversion to a virtual machine corresponding to the display window.
Optionally, before performing coordinate position conversion on the keyboard and mouse message according to a preset rule and generating the keyboard and mouse message after the coordinate position conversion, the method further includes:
judging whether a display window corresponding to the keyboard and mouse message is displayed in a full screen mode or not;
if the display window corresponding to the keyboard and mouse message is full screen display, sending the keyboard and mouse message to the virtual machine corresponding to the display window;
if the display window corresponding to the keyboard and mouse message is not full screen display, converting the coordinate position of the keyboard and mouse message according to a preset rule to generate the keyboard and mouse message after the coordinate position conversion, and sending the keyboard and mouse message after the coordinate position conversion to the virtual machine corresponding to the display window.
It should be noted that, because the desktop zero terminal device side generates a corresponding display window for each desktop image, the desktop zero terminal also needs to perform layout and control on each display window locally, which specifically includes the following aspects:
arranging and displaying all windows according to a preset display window control rule;
and receiving the control action of the user on the display window and executing corresponding control processing.
An exemplary display window control rule is: tiling all display windows on a screen, and directly performing control operation among a plurality of windows by a user; a user amplifies one window through a preset mouse or keyboard operation to enable the window to be displayed in a full screen mode, and other display windows are hidden; a user switches the current window to be amplified and displayed through a preset mouse or keyboard operation, and switches the current window to another window; or, the user calls all the display windows through a preset mouse or keyboard operation, so that all the display windows are tiled on the screen.
Another exemplary control rule for a display window is: tiling all windows at the bottom of a screen in a thumbnail mode, wherein the upper part of the screen is a main window, and a desktop image corresponding to a thumbnail selected by a user is displayed in the main window; when the user switches the display screen of the main window, only the corresponding thumbnail needs to be clicked; the user can make all display windows tiled on the desktop for displaying through preset mouse or keyboard operation.
