In the embodiment of the present invention, a complete process of copying and pasting a file is referred to as a file copy, and accordingly, the file copy event mentioned herein also includes a file copy event and a file paste event.
In order to achieve the purpose of the invention, the invention provides a cloud desktop file copying method, a device and equipment for achieving the method, and the basic idea of the invention is as follows: the file copy detection service is respectively deployed in the local terminal and the cloud desktop, when a file copy event is detected, the copied file list and the directory where the file is located are transmitted to the opposite terminal, the file copy detection service of the opposite terminal calls a directory mount interface to mount the directory where the copied file is located in a file system of the local terminal, a corresponding copy event is generated in a simulated mode so that a clipboard object can be enabled, and when a pasting event is detected, pasting processing can be executed through the clipboard object. According to the technical scheme, the copied file does not need to be transferred in an intermediate medium, so that the copying efficiency is improved, and the user experience is improved.
Based on the basic idea of the invention, specific implementation procedures of the invention are described below in conjunction with the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural diagram of a cloud desktop access framework on which a cloud desktop file copying method provided by an embodiment of the present invention is based. The functions of the modules or components involved in the embodiments of the present invention are described below with reference to the drawings. The local terminal 101 includes a cloud desktop client 110, a local copy event detection service 112, and a local file mount service 113.
The cloud desktop client 110 is used for establishing a communication protocol connection with the cloud desktop monitoring service 120 in the cloud desktop to realize access of the cloud desktop;
after a user starts a cloud desktop client 110 (client for short) at a local terminal, the cloud desktop client 110 may start a local copy event detection service 112 and a local file system mount service 113 in a correlated manner.
The local copy event detection service 112 is configured to detect a file copy event for a local file generated by a local operating system, and send a file list of the local copy and a directory where the file is located to the cloud desktop, so that the cloud copy event detection service 122 simulates in the cloud desktop to generate a corresponding file copy event. When the file is copied from the cloud desktop to the local terminal, the module is further configured to receive, through the cloud desktop client 110, a file list copied in the cloud desktop and a directory where the file is located, which are sent by the virtual machine, and simulate and generate a corresponding file copying event in the local terminal.
And the local file system mount service 113 is configured to provide a mount interface for the local copy event detection service 112, and mount a file directory in the cloud desktop virtual file system to a file system of the local terminal.
The cloud desktop monitoring service 120 is used for establishing a communication protocol connection with the cloud desktop client 110 in the local terminal and providing cloud desktop service for the local terminal;
after the virtual machine on the server side providing the cloud desktop for the user is started, the cloud desktop monitoring service 120 is started in a correlated manner. Cloud desktop monitoring service 120 may associate cloud copy event detection service 122 with cloud file system mount service 123.
Based on the design of a Virtual Desktop Infrastructure (VDI), when a user accesses a cloud Desktop through the cloud Desktop client 110, the cloud Desktop management platform may assist the cloud Desktop client in establishing a Virtual Desktop Protocol (VDP) connection with a bound Virtual machine.
In the implementation of the present invention, the message interaction between the local copy event detection service 112 and the cloud copy event detection service 122 can be forwarded through the communication connection between the cloud desktop client 110 and the cloud desktop monitoring service 120.
The cloud copy event detection service 122 is configured to detect a file copy event, which is generated by the cloud desktop operating system and is for a file in the cloud desktop virtual file system, and send the copied file list and the directory where the file is located to the local terminal, so that the local copy event detection service 112 simulates in the local terminal to generate a corresponding file copy event. When the file is copied from the local terminal to the cloud desktop, the module is configured to receive a file list copied at the local terminal and a directory where the file is located, which are sent by the local terminal, through the cloud desktop monitoring service 120, and simulate and generate a corresponding file copying event in the cloud desktop.
And the cloud file system mounting service 123 is configured to provide a mounting interface for the cloud copy event detection service 122, and mount a file directory in the local terminal file system to the cloud desktop virtual file system.
In order to make the technical solution of the present invention clearer, the file copying process is divided into two directions from the local terminal 101 to the cloud desktop 102 and from the cloud desktop 102 to the local terminal 101, and is described separately below.
The steps of the process of copying the file from the local terminal 101 to the cloud desktop 102 are as follows:
step s101, when the local copy event detection service 112 detects a file copy event for a local file generated by a local operating system, sending a file list of the local copy and a directory where the file is located to the cloud copy event detection service 122;
the cloud desktop client 110 runs on an operating system of the local terminal in the local terminal, and a user may perform a copy operation on a local file in a file browser of the local operating system, or may perform a copy operation on a file located on a cloud desktop virtual file system in a cloud desktop client window.
The copy operation for the local file in the local terminal operating system generates a copy event in the local operating system, and the local copy event detection service 112 detects and captures the copy event generated by the local operating system through an API interface provided by the operating system, and obtains a list of copied files and a directory (absolute path directory) where the files are located.
Based on the implementation logic of the virtual desktop infrastructure, a keyboard or a mouse event generated by mouse and keyboard operations in a cloud desktop client window, that is, a cloud desktop, is redirected to the virtual machine, the virtual machine generates a corresponding replication event in a virtual machine operating system after receiving the redirected keyboard or mouse event, and the cloud copy event detection service 122 can detect the replication event in the virtual machine.
Step s102, after receiving the file list and the directory where the file is located sent by the local terminal, the cloud copy event detection service 122 invokes a mount interface provided by the cloud file system mount service 123 to perform remote directory mount, and generates a clipboard object in the copy event enabled virtual machine in a simulated manner;
cloud copy event detection service 122 uses the received list of files and the directory of the files to simulate generating a copy event in the virtual machine, where generating the copy event enables the virtual machine clipboard object. The copy event generated by simulation records the received information of the file list, the directory of the file and the like into the clipboard object, so that the state of the clipboard object is in a pasting state. For example, in Windows, when a clipboard object of an operating system is in a paste-able state, and a user clicks a right mouse button in a file browser, a "paste" menu item in a pop-up menu is in an available state.
Optionally, in an embodiment of the present invention, the virtual machine mounts the directory where the file of the local terminal is located to a specified hidden directory in the cloud desktop virtual file system in a read-only manner, so as to avoid misoperation and ensure file security.
In an embodiment of the present invention, the cloud copy event detection service 122 executes the mount operation of the directory where the copied file is located each time the file list and the directory where the file is located sent from the local terminal are received, and accordingly, the mounted directory needs to be unloaded when the paste processing and the clipboard object disabling are completed. This approach is complicated and inefficient. In this case, the clipboard object is disabled by the user pressing the copy key and then not pressing the paste key, and then performing a processing action to disable the previous copy operation. For example, after the user presses the Ctrl + C copy key on the selected file in the browser, the Ctrl + V paste key is not pressed on the local terminal or the cloud desktop, and then a text segment is copied into the document, and the previous file copy operation is disabled by the copy operation for copying the text.
In order to simplify the processing process and improve the efficiency of file replication, in another embodiment of the present invention, when the cloud copy event detection service 122 receives the file list and the directory where the file is located sent by the local terminal for the first time, the root directory of the file system of the local terminal is mounted in the specified hidden directory in the cloud desktop virtual file system in a read-only manner, and since the root directory is mounted to the specified hidden directory, the directory does not need to be mounted every time after the file list and the directory where the file is located for the replication operation of other files sent by the local terminal are subsequently received, and when the cloud desktop is pasted, the replicated file can be read from the specified hidden directory mounted in the local terminal virtual file system directly according to the directory where the file is located. Accordingly, only when the cloud desktop client is closed or the virtual machine is closed, the uninstalling operation of the mounted root directory is executed.
Step s103, the cloud copy event detection service 122 pastes the file in the clipboard object to a target directory in the virtual file system of the virtual machine when detecting a file paste event.
After a user selects a target directory of a file to be pasted in a window of the cloud desktop client 110, pressing a paste button or executing a paste operation with a mouse generates a keyboard or mouse event, the generated keyboard or mouse event is redirected to the cloud desktop, the virtual machine generates a corresponding paste event in the virtual machine operating system after receiving the redirected keyboard or mouse event, and the cloud desktop operating system can complete a paste processing process through a clipboard object. And calling the clipboard object in the process of executing the pasting processing, reading the file from the specified hidden directory mounted in the virtual file system according to the copied file list and the directory where the file is located, which are stored in the object and sent by the local terminal, and copying and writing the file into the target directory.
The process of copying the file from the cloud desktop to the local terminal 101 is as follows:
step s201, when the cloud copy event detection service 122 detects a file copy event for a file in the cloud desktop virtual file system, sending a copied file list and a directory where the file is located to the local copy event detection service 112 in the local terminal;
when a user performs a copy operation on a local file located in a cloud desktop virtual file system in a cloud desktop client window, as described above, a copy event is generated in the cloud desktop operating system in the redirection process, and after detecting the copy event, the cloud copy event detection service 122 obtains a copied file list and a directory where the file is located based on the copy event and sends the copied file list and the directory where the file is located to the local copy event detection service 112.
Step S202, when receiving a file list copied in a cloud desktop and a directory where a file is located, which are sent by a cloud-end copy event detection service 122 in a virtual machine, a local copy event detection service 112 calls a mount interface provided by a local file system mount service 113 to mount a remote directory, and simulates to generate a file copy event to enable a clipboard object in a local terminal;
the local copy event detection service 112 uses the received list of files and the directory of the files to simulate generating a corresponding file copy event in the local terminal, the operation of generating the file copy event enabling the local clipboard object.
In an embodiment of the present invention, the local copy event detection service 112 mounts the directory of the received file sent by the virtual machine to the designated hidden directory in the local file system in a read-only manner each time, and the mounted directory needs to be unloaded when the file paste processing and the clipboard object disabling are completed.
In another embodiment of the present invention, when the local copy event detection service 112 receives the copied file list and the directory where the file is located sent by the virtual machine for the first time, the root directory of the virtual file system of the virtual machine is mounted in the specified hidden directory in the local file system in a read-only manner, and since the root directory of the virtual file system of the virtual machine is already mounted in the local specified hidden directory, the directory does not need to be mounted each time after the copied file list and the directory where the file is located sent by the cloud desktop terminal are subsequently received, and the copied file can be read from the specified hidden directory directly according to the directory where the file is located when pasting. When the cloud desktop client is closed, the local terminal needs to execute the uninstalling operation of the mounted root directory.
Step S203, when the file pasting event is detected, pasting the file in the clipboard object to a target directory in the local file system.
When a user selects a target directory of a file to be pasted in a local file browser, and presses a paste key or executes a paste operation by using a mouse, an operating system generates a file paste event, and the local file browser executes a paste process after responding to the paste event. A file paste event in the local operating system may also be detected by the local copy event detection service 112, and the paste process performed by the local copy event detection service 112. And calling the clipboard object in the pasting process, reading the file from the specified hidden directory mounted in the local file system according to the copied file list and the file directory which are stored in the object and transmitted by the virtual machine, and copying and writing the file into the target directory.
Some clients have a large network bandwidth, and if a file is copied between a cloud desktop and a local terminal, the file occupies a large bandwidth, and affects other functions, such as a mouse and a keyboard cannot respond in time, a display is stuck, and the like, but the effect is larger when a large file is copied, so in an embodiment of the present invention, the file copying process performed based on the embodiment of the present invention is limited to occupy the bandwidth, for example, a message of the copied file is transmitted through a channel between the cloud desktop client 110 and the cloud desktop monitoring service 120, configuration parameters can be provided for the cloud desktop client 110 and the cloud desktop monitoring service 12 through the configuration file, and the number of parallel copied files and the bandwidth occupied when the file is copied and transmitted are limited, so as to reduce the network bandwidth occupied by the file.
