Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
For convenience of explaining the technical solution of the present invention, an application scenario of the present invention will be briefly described below with reference to fig. 1. Referring to fig. 1, a browser is loaded in a first mobile terminal 100 (i.e., a local control end), and the first mobile terminal 100 is in communication connection with a second mobile terminal 200 (i.e., a remote controlled end) through a protocol relay gateway 300, a user can implement a remote desktop control operation on the second mobile terminal 200 through the browser loaded in the first mobile terminal 100, the protocol relay gateway 300 performs information transmission with the browser of the first mobile terminal 100 and the second mobile terminal 200 respectively using different communication protocols, and can convert received information into texts in different communication protocol formats for transmission. In the prior art, due to a protection mechanism of a browser, the browser cannot directly monitor and modify a clipboard of the first mobile terminal 100, a user cannot copy or cut content in the first mobile terminal 100 in the second mobile terminal 200 through a remote desktop operation, and a user cannot copy or cut content in the second mobile terminal 200 through a remote desktop operation in the first mobile terminal 100. In this embodiment, the content copied or cut by the user in the first mobile terminal 100 is synchronized to the clipboard of the second mobile terminal 200, so that the user can perform the paste operation of the same content when operating the second mobile terminal 200 through the remote desktop; similarly, when the user operates the second mobile terminal 200 to copy or cut on the remote desktop, the clipboard of the first mobile terminal 100 is synchronized to perform the same operation, so that the user can perform the same content pasting operation on the first mobile terminal 100.
Example one
An embodiment of the present invention provides a cross-platform cloud clipboard implementation method based on a browser, and referring to fig. 2, the method may include:
step S11, a preset extension program is loaded for a browser arranged in a first mobile terminal, when a user performs remote desktop control operation on a second mobile terminal through the browser in the first mobile terminal, a local service is created for the first mobile terminal, the local service is used for realizing management of the browser of the first mobile terminal on a clipboard of the first mobile terminal, and the browser of the first mobile terminal is in communication connection with the second mobile terminal through a protocol transit gateway.
It should be noted that, in the existing remote desktop access technology, the clipboard contents between the local control end and the remote controlled end are intercommunicated, but only specific clients (such as QQ, etc.) need to be loaded in both the local control end and the remote controlled end. However, in the prior art, based on remote desktop access initiated by a browser, due to a security protection mechanism of the browser, the browser cannot directly access and modify the content of the clipboard of the local control end where the browser is located, so that when the remote desktop access based on the browser is performed, the clipboard content intercommunication between the local control end and the remote controlled end cannot be realized.
Specifically, in order to manage a clipboard of a first mobile terminal where a browser is located, a preset extension program is loaded for the browser arranged on the first mobile terminal, the extension program is created based on a browser extension mechanism, when a user performs remote desktop control operation on a second mobile terminal through the browser in the first mobile terminal, the extension program creates a local service for the first mobile terminal, and the local service communicates with the browser through a preset local information mechanism.
In this embodiment, the first mobile terminal is loaded with a browser, and is a local control end that initiates a remote desktop access for a user, where the browser of the first mobile terminal is in communication connection with the second mobile terminal through the protocol transit gateway, and the second mobile terminal is a remote controlled end. A browser extension mechanism is adopted in a browser of the first mobile terminal, and a local service is created for the first mobile terminal to interact with the browser and a clipboard of the first mobile terminal respectively. The local service implements management of clipboard copying (reading clipboard) and pasting (modifying clipboard) of the first mobile terminal through the first mobile terminal-independent interface. The local service performs information interaction with the browser through a Native Messaging mechanism (namely, a local information mechanism). Preferably, the local service is started and stopped along with the starting and stopping of the remote desktop of the browser, so that the memory running pressure is relieved.
Step S12, if the user performs the remote desktop control operation on the second mobile terminal through the browser in the first mobile terminal, the local service in the first mobile terminal monitors whether the clipboard of the first mobile terminal has the copy-cut event, or the browser of the first mobile terminal monitors whether the browser of the first mobile terminal receives the copy-cut event of the remote desktop control operation sent by the protocol transit gateway, where the copy-cut event of the remote desktop control operation is fed back to the protocol transit gateway by the second mobile terminal when the clipboard of the second mobile terminal has the copy-cut event.
In this embodiment, when a user initiates a remote desktop access to a second mobile terminal through a browser of a first mobile terminal, whether a copy and cut event occurs in clipboards of the first mobile terminal and the second mobile terminal is monitored respectively.
Step S13, when the local service in the first mobile terminal monitors that the clipboard of the first mobile terminal has the copy-cut event, the local service in the first mobile terminal transmits the monitored copy-cut event to the browser in the first mobile terminal, the browser in the first mobile terminal transmits the received copy-cut event to the second mobile terminal through the protocol transit gateway, and the second mobile terminal modifies the clipboard thereof, so that the clipboard of the second mobile terminal has the same copy-cut event as that of the first mobile terminal.
In this embodiment, when the second mobile terminal receives the copy and cut event transmitted by the protocol transit gateway, it may directly control its clipboard to perform corresponding copy and cut.
Specifically, the step S13 may be implemented as follows:
1, when a local service in a first mobile terminal monitors that a clipboard of the first mobile terminal generates a copy and cut event, the local service in the first mobile terminal transmits the monitored copy and cut event to a browser in the first mobile terminal through a local information mechanism.
2, the browser in the first mobile terminal transmits the copy cut event to the protocol transit gateway through the first communication protocol.
And 3, the protocol transit gateway converts the received copy cutting event and transmits the copy cutting event to the second mobile terminal through a second communication protocol.
In this embodiment, the first communication Protocol may be a web socket Protocol of HTML5, where the web socket Protocol is a new network Protocol based on Transmission Control Protocol (TCP), and it implements full duplex communication between the browser and the server — allowing the server to actively send information to the client. The second communication protocol may be a remote access protocol supporting copy-and-paste, such as: remote Desktop Protocol (Remote Desktop Protocol, abbreviated as "RDP").
In this embodiment, when it is monitored that a clipboard of a first mobile terminal has a copy-cut event, a local service in the first mobile terminal transmits the monitored copy-cut event to a browser of the first mobile terminal through a local information mechanism, and the browser of the first mobile terminal transmits a received copy-cut event to a second mobile terminal through a protocol relay gateway, so that the clipboard of the second mobile terminal has the same copy-cut event.
Step S14, when the browser of the first mobile terminal receives the copy and cut event of the remote desktop control operation sent by the protocol transit gateway, the browser of the first mobile terminal forwards the copy and cut event to the local service of the first mobile terminal, and the local service of the first mobile terminal modifies the clipboard of the first mobile terminal, so that the clipboard of the first mobile terminal generates the same copy and cut event as the second mobile terminal.
It should be noted that, the above step S14 and step S13 are not sequentially executed, and their implementation is determined by whether the clipboard in the first mobile terminal or the second mobile terminal is copied or clipped.
Specifically, the step S14 may be implemented as follows:
1, when a browser of a first mobile terminal receives a copy and cut event of a remote desktop control operation sent by a protocol transit gateway, the browser of the first mobile terminal forwards the copy and cut event to a local service of the first mobile terminal through a local information mechanism.
In this embodiment, when a clipboard in the second mobile terminal has a copy and cut event of a remote desktop control operation, the second mobile terminal transmits the copy and cut event of the remote desktop control operation to the browser of the first mobile terminal through the protocol relay gateway, and the browser of the first mobile terminal transmits the copy and cut event to the local service of the first mobile terminal, so as to control the clipboard of the first mobile terminal to have the same copy and cut event.
According to the embodiment of the invention, the preset extension program is loaded to the browser arranged on the first mobile terminal, and when a user performs remote desktop control operation on the second mobile terminal through the browser in the first mobile terminal, the extension program creates a local service for the first mobile terminal, wherein the local service is used for realizing the management of the browser of the first mobile terminal on the clipboard of the first mobile terminal. When a clipboard in a first mobile terminal has a copy-cut event, a browser of the first mobile terminal can receive the copy-cut event and transmit the copy-cut event to a second mobile terminal, so that the clipboard of the second mobile terminal is correspondingly modified by the second mobile terminal; when the clipboard of the second mobile terminal generates a copy and cut event of remote desktop control operation, the browser in the first mobile terminal receives the copy and cut event and transmits the copy and cut event to the local service, and the clipboard of the first mobile terminal is modified correspondingly through the local service. Therefore, the content interaction of the clipboards of the first mobile terminal and the second mobile terminal is realized, the function of a remote desktop based on a browser is enhanced, and the cross-platform and cross-browser cloud clipboard functions are realized. In addition, the monitoring and auditing functions of the remote desktop clipboard can be further realized.

It should be noted that, in the existing remote desktop access technology, the clipboard contents between the local control end and the remote controlled end are intercommunicated, but only specific clients (such as QQ, etc.) need to be loaded in both the local control end and the remote controlled end. However, in the prior art, based on remote desktop access initiated by a browser, due to a browser security protection mechanism, the browser cannot directly access and modify the content of the clipboard of the local control end where the browser is located, so that when the remote desktop access is based on the browser, clipboard content intercommunication between the local control end and the remote controlled end cannot be achieved.
Specifically, in order to manage a clipboard of a first mobile terminal where a browser is located, a preset extension program is loaded for the browser arranged on the first mobile terminal, the extension program is created based on a browser extension mechanism, when a user performs remote desktop control operation on a second mobile terminal through the browser in the first mobile terminal, the extension program creates a local service for the first mobile terminal, and the local service communicates with the browser through a preset local information mechanism.
In this embodiment, the first mobile terminal is loaded with a browser, and is a local control end that initiates remote desktop access for a user, where the browser of the first mobile terminal is in communication connection with the second mobile terminal through the protocol transit gateway, and the second mobile terminal is a remote controlled end. A browser extension mechanism is adopted in a browser of the first mobile terminal, and a local service is created for the first mobile terminal to interact with the browser and a clipboard of the first mobile terminal respectively. The local service implements management of clipboard copying (reading clipboard) and pasting (modifying clipboard) of the first mobile terminal through the first mobile terminal-independent interface. The local service performs information interaction with the browser through a Native Messaging mechanism (namely, a local information mechanism). Preferably, the local service is started and stopped along with the starting and stopping of the remote desktop of the browser, so that the memory running pressure is relieved.
The first mobile terminal 100 is further configured to, when the local service in the first mobile terminal monitors that a copy-cut event occurs in the clipboard of the first mobile terminal, transmit the monitored copy-cut event to the browser in the first mobile terminal through the local service in the first mobile terminal, and transmit the received copy-cut event to the second mobile terminal through the protocol transfer gateway through the browser in the first mobile terminal.
The second mobile terminal 200 is configured to modify the clipboard according to the received copy-cut event, so that the clipboard of the second mobile terminal has the same copy-cut event as the first mobile terminal.
In this embodiment, when it is monitored that a clipboard of a first mobile terminal has a copy-cut event, a local service in the first mobile terminal transmits the monitored copy-cut event to a browser of the first mobile terminal through a local information mechanism, and the browser of the first mobile terminal transmits a received copy-cut event to a second mobile terminal through a protocol relay gateway, so that the clipboard of the second mobile terminal has the same copy-cut event.
The second mobile terminal 100 is further configured to transmit the copy-cut event of the remote desktop control operation to the browser of the first mobile terminal through the protocol transit gateway when the copy-cut event of the remote desktop control operation occurs on the clipboard of the second mobile terminal.

Alternatively, the first communication protocol may be a web socket protocol of HTML5, and the WebSocket protocol is a new network protocol based on TCP, and it implements full duplex communication between the browser and the server — allowing the server to actively send information to the client. The second communication protocol may be a remote access protocol supporting copy and paste, for example: the RDP protocol.
