Description
Technical field
The present invention relates to computer realm, more particularly to a kind of method of cursor synchronization, relevant device and system.
Background technology
With the rise of cloud, conventional desktop working way gradually substitutes by desktop cloud mode, i.e. virtual desktop
Infrastructure (Virtual Desktop Infrastructure, referred to as " VDI ").Cloud Server, table are accessed by desktop cloud
, it is necessary to which the operation information of the cursor of client is delivered into server end in the cloud of face, to cause the cursor operations of client
Perform and come into force in server end, for example, the cursor of user's mobile client, client is controlled by the cursor in local system
Related application programming interfaces (Application Programming Interface, API), obtain the state of cursor key
And current location information, then pass through the client cursor operations information transmission that protocol is obtained to server end, service
Device termination receives the operation information and then the cursor setting of client is arrived into relevant position and state by the API of correlation.
How to show and handle cursor information at client and server end is a unavoidable technical problem, existing
The first scheme in technology is after client gets the cursor information of oneself, first shows light according to the cursor information of itself
Move target position so that user promptly appreciates that the movement of cursor position, then transmits local terminal cursor information, service to server end
After device end gets the cursor information of client and performs the cursor operations at associated server end, server end does not show itself
Cursor, and send the cursor graphic of itself to client, client is straight in the cursor position for having been displayed to user before
Connect the server cursor shape that display receives.
Second scheme of the prior art is that publication No. is obtaining for the scheme disclosed in CN106843537A, client
To after the cursor information of itself, server end is passed it to, server end gets the cursor information of client simultaneously
After the cursor operations for performing associated server end, server end shows the cursor of itself, and send the cursor information of itself to
Client so that the cursor of client is synchronous with the cursor holding of server end.
In the first scheme, the cursor position of client and the cursor of server end are unable to precise synchronization, when user needs
Running some in the virtual desktop of server end needs cursor to show or to the higher program of cursor position control accuracy or peripheral hardware
When, such as when electronic whiteboard, handwriting pad and shooting game and image scaling software, due to the cursor position of not feedback server side
Put, customer side is inaccurately synchronous with the cursor position of server side, causes user to produce mistake using these application programs or peripheral hardware
Operation, Consumer's Experience are bad.
In second scheme, server end can be to the cursor position information of client feedback server end, in information transmission
Process needs to expend the time so that server end can be synchronous in the presence of delay with the cursor of client, for most of application programs
For, and do not need the cursor in virtual machine to show or not high to the accuracy requirement of cursor synchronization, if using second of side completely
Case, the presence of this delay, reduces Consumer's Experience.
The content of the invention

103rd, the real time information of server end cursor is sent to client.
In target process implementation procedure is got or target device server end cursor in use it is real-time
After information, server can send the real time information of server side cursor to corresponding client, make it that client can be with
Position and the shape of the cursor of client or peripheral hardware are adjusted, makes it synchronous with the holding of server end cursor.
Understand above, when the target process in white list starts or target device enables, server can obtain target
During process performs or target device server end cursor during use real time information, and by the reality of the server end cursor
When information be sent to client, to allow client to adjust the cursor of client or peripheral hardware so that the target in white list
During process performs or target device client cursor and server end cursor keep precise synchronization during use, when not starting
When target process in white list starts or target device enables, the real-time letter of server end cursor can not be sent to client
Breath, meets the demand of user customer and server end cursor synchronization different levels, improves Consumer's Experience.
The flow of the method for cursor synchronization in the embodiment of the present invention is described above-described embodiment, and it will be entered below
Row is described in detail, referring to Fig. 2, another embodiment of the method for cursor synchronization may include in the embodiment of the present invention：
201st, judge target process or target device whether in preset white list；
202nd, target process perform during or target device during use, obtain server end cursor real time information；
When the target process of startup or the target device that enables are in preset white list, server can obtain target and enter
In journey implementation procedure or target device server side cursor in use real time information, the real time information includes cursor
Positional information and shape information in one or more, specific acquisition modes will be described in detail in follow-up real-time example.
Specifically, when the target device in white list enables, it is necessary to the driver of server side is driven, service
Device can carry out filtration drive monitoring to obtain server end cursor information to target device, and specific filtration drive monitoring is implemented
Mode is prior art, is not repeated herein；When the target process in white list starts, API was carried out to target process
To obtain server end cursor information, specific API HOOK embodiments are prior art, are not repeated herein for HOOK processing.
It is understood that filtration drive monitoring and API HOOK technical limit spacing server side cursor informations in the present embodiment
For preferred scheme, in specific utilization, server side can also pass through other monitoring technologies and obtain server side cursor information, tool
The acquisition modes of body do not limit herein.
203rd, judge whether the real time information of the server end cursor changes；
In target process implementation procedure is got or target device server end cursor in use it is real-time
After information, the cursor real time information of server side can be compared for server, if the cursor information of server side occurs
During change, step 204 can be performed, if not changing, the information can not be sent, perform other operations.
204th, the real time information of server end cursor is sent to client；
If the cursor information of server side changes, server can send server sidelight to corresponding client
Target real time information, with allow client adjust client or peripheral hardware cursor position and shape, make itself and server
Cursor is held to keep synchronous.
Further, when user causes the cursor information of client to change in client operation, in order to keep visitor
The cursor of family end and server end is consistent, and the present embodiment can further include：
205th, the client cursor information that client is sent is received；
After user causes the cursor information of client to change in client operation, server can receive visitor
The client cursor information mark that family end is sent.
206th, server is according to the cursor at client cursor information Redirect Server end.
Server can redirect according to the cursor information of client to the cursor of server end, to complete user's
Mesh is operated, and to the cursor information after client feedback server end redirection, to allow client further to adjust light
Mark so that during target process in white list performs or target device client cursor is protected with server end cursor during use
Precise synchronization is held, the demand of user customer and server end cursor synchronization different levels is met, improves Consumer's Experience.
