Abstract

An embodiment of the present application provides a method, device, and storage medium for accessing cloud applications within a cloud desktop. A cloud application connection establishment module is deployed in the cloud desktop terminal and a cloud application client is deployed in the cloud desktop server. Based on this, when an access instruction for a target cloud application occurs in the cloud desktop, the cloud application client does not establish a connection with the cloud application server where the target cloud application is located. Instead, it provides the authentication information corresponding to the target cloud application to the cloud application connection establishment module, and the cloud application connection establishment module establishes a connection with the cloud application server and receives the undecoded data stream corresponding to the target cloud application. In this way, the undecoded data stream can be directly transmitted to the cloud desktop terminal for the cloud desktop terminal to display the target cloud application in the cloud desktop. This can effectively avoid the problem of secondary streaming when accessing cloud applications in the cloud desktop, thereby effectively reducing the resource overhead on the cloud desktop server, improving the image quality of cloud applications, and / or reducing network latency.

[0002] Currently, in the implementation solution for accessing cloud applications within a cloud desktop, it is necessary to decode the data stream of the cloud application in the cloud desktop server. The cloud desktop server also needs to encode the cloud desktop data and the decoded cloud application data together, and then send the encoded data stream to the cloud desktop terminal for display.

[0003] It can be seen that the existing implementation solution requires two times of streaming and introduces network delays in two stages. This not only brings additional resource overhead to the cloud desktop server, but also causes image quality loss of the cloud application and brings relatively large network delays.

A cloud desktop protocol client and a cloud application connection establishment module are deployed in the cloud desktop terminal. The method includes:

[0010] If the authentication information corresponding to the target cloud application sent by the cloud desktop server is received, the cloud application connection module is used to establish a connection with the cloud application server where the target cloud application is located based on the authentication information, where the authentication information is obtained by the cloud application client deployed in the cloud desktop server in response to an access instruction for the target cloud application in the cloud desktop;

[0021] In the embodiments of the present application, a cloud application connection module is deployed in the cloud desktop terminal and a cloud application client is deployed in the cloud desktop server. Based on this, when an access instruction for a target cloud application occurs in the cloud desktop, the cloud application client does not establish a connection with the cloud application server where the target cloud application is located. Instead, it provides the authentication information corresponding to the target cloud application to the cloud application connection module, and the cloud application connection module establishes a connection with the cloud application server and receives the undecoded data stream corresponding to the target cloud application.

[0032] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0033] At present, in the implementation scheme of accessing cloud applications in a cloud desktop, two streams are required and two stages of network delay are introduced, which not only brings additional resource overhead to the cloud desktop server, but also causes image quality loss of the cloud application and brings large network delay. To this end, in some embodiments of the present application: a cloud application connection module is deployed in the cloud desktop terminal and a cloud application client is deployed in the cloud desktop server. Based on this, when an access instruction for a target cloud application occurs in the cloud desktop, the cloud application client will not establish a connection with the cloud application server where the target cloud application is located, but will provide the authentication information corresponding to the target cloud application to the cloud application connection module, and the cloud application connection module will establish a connection with the cloud application server and receive the undecoded data stream corresponding to the target cloud application. In this way, the undecoded data stream can be directly transmitted to the cloud desktop terminal, and the cloud desktop terminal can display the target cloud application in the cloud desktop based on the undecoded data stream and the originally received cloud desktop data stream, thereby realizing access to the cloud application in the cloud desktop. Accordingly, in the embodiment of the present application, the cloud desktop server does not need to perform any decoding and re-encoding work for the target cloud application. The cloud desktop terminal can directly obtain the undecoded data stream from the cloud application server and perform decoding and rendering. This can effectively avoid the secondary streaming problem when accessing cloud applications in the cloud desktop, and eliminates the two stages of network delay required in traditional solutions, thereby effectively reducing the resource overhead on the cloud desktop server, improving the image quality of cloud applications and / or reducing network delays.

[0034] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0035] Figure 1The structural schematic diagram of a communication system provided for an exemplary embodiment of the present application. As Figure 1 shown, the communication system includes: a cloud desktop server, a cloud desktop terminal, and a cloud application server. Among them, different cloud applications may be in cloud application servers that are not exactly the same. Figure 1 Only one cloud application server is shown herein to assist in describing the solution for accessing a certain cloud application within the cloud desktop. However, it should be understood that multiple cloud application servers can be accessed within this communication system.

[0036] First, several concepts involved in this embodiment are briefly described below:

[0037] A cloud desktop, also known as desktop virtualization or cloud computer, is a new model that replaces traditional computers.

[0038] A cloud desktop server may refer to a cloud server used to support the operation of a cloud desktop. It should be understood that a cloud desktop server may include components such as a CPU, memory, image, and cloud hard disk, and is a cloud server that can be obtained at any time and is elastically scalable.

[0039] A cloud desktop terminal may refer to a terminal device that supports the operation of a cloud desktop. It can connect to the cloud desktop server, render the cloud desktop to the front end, and redirect output and input data such as mouse operations at the front end to the cloud desktop server.

[0040] A cloud application is a new type of application that changes the usage mode of traditional software from "locally installed and locally operated" to "instant use". It connects to and controls a remote cloud application server through the Internet or local area network to complete processing logic or computing tasks. The main carrier of cloud applications is Internet technology, presented in the form of a thin client or a smart client. Cloud applications can not only help users reduce IT costs, but also greatly improve work efficiency. Therefore, the development wave of the transformation of traditional software to cloud applications is irresistible.

[0041] A cloud application server may refer to a cloud server used to support the operation of a cloud application. The processing logic and computing tasks of cloud applications are all completed in the cloud application server. Similar to cloud desktops, in cloud application technology, a cloud application terminal is required for front-end display.

[0042] In this embodiment, based on the foregoing communication system, a solution for accessing cloud applications within a cloud desktop is proposed.

[0043] In this embodiment, it is proposed to use the cloud desktop server as the cloud application terminal corresponding to the target cloud application, where the target cloud application can be any cloud application that needs to be accessed within the cloud desktop. Figure 2 An alternative implementation structure of a communication system provided for an exemplary embodiment of the present application. Refer toFigure 2 In the cloud desktop server, a cloud desktop protocol server and a cloud application client can be deployed. In the cloud desktop terminal, a cloud desktop protocol client is deployed. Among them, the cloud desktop protocol server and the cloud desktop protocol client can transmit data related to cloud desktop operation according to the cloud desktop protocol. The cloud application client can cooperate with the cloud application server to support the operation of cloud applications.

[0044] Optionally, in this embodiment, access to a cloud application can be initiated in the cloud desktop through a browser or a soft terminal. For this purpose, the cloud application client deployed in the cloud desktop server can be implemented as a browser client or a soft terminal, etc. In this way, in the front-end interface of the cloud desktop in this embodiment, the application screen of the cloud application can be displayed in a cloud application window, and the cloud application window can be a browser window or a soft terminal window. It should be understood that the cloud application window is one of the display windows included in the cloud desktop. Therefore, various operations can be performed on the cloud application window in the cloud desktop, such as dragging, scrolling, or resizing, etc.

[0045] It should also be noted here that the cloud desktop originally contains many system applications and local applications. The local applications can be understood as applications running in the cloud desktop server, which are equivalent to applications already installed in the "cloud computer". Moreover, display windows are originally configured for these local applications and system applications in the front-end interface of the cloud desktop. In the case of accessing a cloud application in the cloud desktop, it can be understood that on the basis of the display windows originally included in the front-end interface of the cloud desktop, a display window for displaying the cloud application is added, so as to support the display of the application screen of the cloud application in the cloud desktop.

[0046] Reference Figure 2 In this embodiment, the cloud application client can obtain the authentication information corresponding to the target cloud application in response to an access instruction for the target cloud application occurring in the cloud desktop. In actual application, the cloud application client can display a cloud application login interface in the corresponding display window in the front-end interface of the cloud desktop, and the user can input authentication information in the cloud application login interface to trigger the generation of an access instruction for the target cloud application. In this way, the cloud application client can obtain the authentication information corresponding to the target cloud application in response to the access instruction. Among them, the authentication information can include various information required for connection establishment, such as connection establishment address, username, and password, etc.

[0047] Reference Figure 2, To implement the relevant functional logics mentioned in the cloud application client in this embodiment, in an optional implementation architecture, a Software Development Kit (SDK) can be deployed in the cloud application client. The SDK can be implemented as a browser process or a soft terminal process in the cloud desktop server, etc. Further, a custom plugin can be preset in the SDK included in the cloud application client. After the cloud application client runs, the custom plugin can be executed. Based on the custom plugin, the aforementioned access instruction can be intercepted, the connection between the cloud application client and the cloud application server can be prohibited, and the aforementioned authentication information can be obtained.

[0048] On this basis, in the cloud desktop server, the authentication information can be transmitted to the cloud application connection module deployed in the cloud desktop terminal. Among them, the cloud application connection module can also be implemented as an SDK, and this module is specifically used to handle the connection work with the cloud application server. It should be understood that connection means that both parties establish a connection channel and transmit data streams through the connection channel.

[0049] In an optional implementation solution, the authentication information can be transmitted to the cloud application connection module in a pass-through manner. For this purpose, refer to Figure 2 , a first transmission module can be deployed in the cloud application client, and a second transmission module can be deployed in the cloud desktop protocol server. A transmission protocol can be pre-agreed between the first transmission module and the second transmission module. Based on this, the first transmission module can transmit the obtained authentication information to the second transmission module according to the transmission protocol. Among them, the transmission protocol agreed upon by both parties here can be the websocket protocol. Of course, in this embodiment, the transmission protocol can also be the pipe protocol, as well as other protocols that can meet the inter-process transmission requirements that may appear now or in the future. This embodiment is not limited to this. Refer to Figure 2In addition to the data channel originally used to transmit cloud desktop related data between the cloud desktop protocol server and the cloud desktop protocol client, more customized channels can be added. These customized channels can provide transmission support for the data that needs to be transmitted from the cloud desktop protocol server to the cloud desktop protocol client in this embodiment. Based on this, the cloud desktop protocol server can transmit the authentication information received by the second transmission module to the cloud desktop protocol client through the corresponding customized channel. Under these customized channels, serialization and deserialization technology can be used for data interaction between the cloud desktop protocol server and the cloud desktop protocol client. Using serialization and deserialization technology, content can be efficiently transmitted between processes and networks. Among them, serialization can be understood as saving an object into a byte sequence, and deserialization can be understood as converting the byte sequence into the original object for use. Based on this, the cloud desktop protocol server can serialize the authentication information and then send it to the cloud desktop protocol client. The cloud desktop protocol client can deserialize the authentication information sent by the cloud desktop protocol server to restore the authentication information. Continue to refer to Figure 2 The cloud desktop protocol client and the cloud application connection module can be implemented as two SDK instances in the cloud desktop terminal. In this way, the cloud desktop protocol client can transmit the authentication information to the cloud application connection module according to the existing or future inter-instance communication method.

[0050] Thus, in the above optional implementation scheme, the transparent transmission path of the authentication message can be: cloud application client (first transmission module) - cloud desktop protocol server (second transmission module) - cloud desktop protocol client - cloud application connection module.

[0051] It should be understood that in this embodiment, other implementation schemes may also be used to transmit the authentication message to the cloud application connection module, for example, directly transmitting through the network, etc., and this embodiment is not limited thereto.

[0052] Afterwards, after receiving the authentication information, the cloud application connection module can establish a connection with the cloud application server where the target cloud application is located based on the authentication information. And after the connection is successfully established, the undecoded data stream corresponding to the target cloud application can be received from the cloud application server. It can be seen that in this embodiment, the cloud application server can transmit the undecoded data stream corresponding to the target cloud application directly to the cloud desktop terminal, and it is no longer necessary to transmit it to the cloud desktop server. Compared with the traditional solution, this eliminates the two-stage network delay and secondary streaming problems, that is, in this embodiment, the cloud desktop server no longer needs to receive the undecoded data stream, no longer needs to decode it, no longer needs to encode the decoded cloud application data together with the cloud desktop data, and no longer needs to transmit the cloud application data to the cloud desktop terminal based on the re-encoded data stream.

[0053] refer to Figure 2, in this embodiment, the cloud desktop protocol server may also transmit the cloud desktop data stream to the cloud desktop protocol client. It should be understood that the undecoded data stream corresponding to the target cloud application and the cloud desktop data stream mentioned here may include image data, voice data, and / or keyboard and mouse data, etc. This embodiment does not limit the data types included in the data stream, and can be set according to the operation requirements of the cloud application and the cloud desktop.

[0054] In addition, the cloud desktop protocol client may also receive the undecoded data stream corresponding to the target cloud application from the cloud application connection establishment module. In this way, the cloud desktop protocol client can obtain the cloud desktop data stream and the undecoded data stream corresponding to the target cloud application. On this basis, the cloud desktop protocol client can display the target cloud application in the cloud desktop based on these two data streams.

[0055] In summary, in this embodiment, the cloud application connection establishment module is deployed in the cloud desktop terminal and the cloud application client is deployed in the cloud desktop server. Based on this, when an access instruction for the target cloud application occurs in the cloud desktop, the cloud application client will not establish a connection with the cloud application server where the target cloud application is located, but provide the authentication information corresponding to the target cloud application to the cloud application connection establishment module, and the cloud application connection establishment module will establish a connection with the cloud application server and receive the undecoded data stream corresponding to the target cloud application. In this way, the undecoded data stream can be directly transmitted to the cloud desktop terminal, and the cloud desktop terminal can display the target cloud application in the cloud desktop based on the undecoded data stream and the originally received cloud desktop data stream, so as to realize the access to the cloud application within the cloud desktop. Accordingly, in the embodiment of the present application, there is no need to perform any decoding and re-encoding work for the target cloud application in the cloud desktop server, and the cloud desktop terminal can directly obtain the undecoded data stream from the cloud application server and perform decoding and rendering, which can effectively avoid the problem of secondary streaming when accessing the cloud application in the cloud desktop, and eliminate the network delay in two stages required in the traditional solution, thereby effectively reducing the resource overhead on the cloud desktop server, improving the image quality of the cloud application and / or reducing the network delay.

[0056] In the above or following embodiments, in order to cope with various emergencies or the problem of restricted access to some cloud applications, in addition to the direct connection solution (the cloud application server directly connects to the cloud desktop terminal) provided in the foregoing embodiments, a relay solution is also provided. The switching timing of the two solutions will be described in detail below, and the relay solution will be described in detail.

[0057] Figure 3 It is an alternative implementation structure of another communication system provided for an exemplary embodiment of the present application. Refer to Figure 3, in this embodiment, for the cloud desktop server, in the case where it is determined that the cloud application connection module fails to establish a connection with the cloud application server where the target cloud application is located, the transfer scheme can be switched. That is, after the cloud application connection module fails to establish a connection with the cloud application server, the cloud application connection module no longer attempts to establish a connection with the cloud application server. In practical applications, the cloud application connection module can transmit a connection failure notification to the cloud desktop server. For example, referring to the exemplary pass-through path provided for the authentication information in the foregoing embodiment, the connection failure notification can be transmitted back to the cloud application client through this pass-through path.

[0058] Under this trigger, the cloud application client can establish a connection with the cloud application server based on the authentication information corresponding to the target cloud application and receive the undecoded data stream corresponding to the target cloud application from the cloud application server. Refer to Figure 3 , the cloud application server is no longer directly connected to the cloud desktop terminal, but is communicatively connected to the cloud desktop server, specifically, connected to the cloud application client deployed in the cloud desktop server.

[0059] In the transfer scheme provided in this embodiment, the cloud application client will not decode the undecoded data stream corresponding to the target cloud application either, but will transmit the undecoded data stream to the cloud desktop protocol server; and the cloud desktop protocol server will then transmit the undecoded data stream to the cloud desktop protocol client. It can be understood that in the transfer scheme, the undecoded data stream will also be finally transmitted to the cloud desktop protocol client just like in the direct connection scheme. After the undecoded data stream is transmitted to the cloud desktop protocol client, the cloud desktop protocol client can adopt the same processing logic in both the transfer scheme and the direct connection scheme to display the target cloud application on the cloud desktop.

[0060] Here, refer to Figure 3 , in an optionally implemented solution, referring to the exemplary pass-through path provided for the authentication information in the foregoing embodiment, the undecoded data stream corresponding to the target cloud application can be passed through from the cloud application client to the cloud desktop protocol client. It should be noted here that more customized channels added additionally between the cloud desktop protocol server and the cloud desktop protocol client can be used to transmit different types of data that occur additionally in this embodiment. For example, the foregoing authentication information can be transmitted through the first customized channel, and the undecoded data stream required here can be transmitted through the second customized channel. In this way, appropriate channels can be selected for different types of data to ensure the timeliness and accuracy of data transmission.

[0061] In addition, in the transfer scheme, the cloud application connection module deployed in the cloud desktop terminal is no longer used. Of course, it should be understood that the cloud application connection module can be used in the access process of other cloud applications.

[0062] Figure 4A schematic diagram of communication logic within a communication system provided by an exemplary embodiment of the present application. Refer to Figure 4 , based on the relay solution provided in this embodiment, a judgment logic can be added to the cloud application client: after receiving the aforementioned access instruction, it can be determined whether a cloud application connection module is deployed in the cloud desktop terminal. If not, the relay solution can be switched to, and it is no longer necessary to transmit the aforementioned authentication information to the cloud desktop terminal; if so, the authentication information can continue to be transmitted to the cloud application connection module according to the direct connection solution; afterwards, it can be further determined whether the cloud application connection module is successfully connected to the cloud application server. If so, the direct connection solution can continue to be executed; if not, the relay solution can be switched to.

[0063] In this way, in the event of an emergency or problems with restricted access to some cloud applications, a fallback mechanism can be supported to fallback from the direct connection solution to the relay solution, thereby addressing emergencies or problems with restricted access to some cloud applications. The emergencies or problems with restricted access to some cloud applications here may include, but are not limited to, that the target cloud application is only allowed to be accessed in a virtual private cloud (VPC) environment, or that the cloud application connection module is not deployed in the cloud desktop terminals used by some users, etc.

[0064] Accordingly, in this embodiment, a relay solution is provided. The cloud application server is connected to the cloud desktop server. However, neither the cloud application client nor the cloud desktop protocol server deployed in the cloud desktop server will decode the undecoded data stream provided by the cloud application server, but instead transparently transmit the undecoded data stream to the cloud desktop protocol client. It can be seen that the relay solution can also avoid the problem of secondary streaming, thereby avoiding image quality loss. Since a lot of encoding and decoding work is eliminated, the network latency can also be reduced to a certain extent.

[0065] In the above or following embodiments, since it is necessary to display cloud applications on the cloud desktop, therefore, how to ensure the accuracy of the display is an urgent problem to be solved. For this reason, a solution is proposed in this embodiment. It should be noted that the solution provided in this embodiment is common to the aforementioned direct connection solution and relay solution.

[0066] Refer to Figure 2 and Figure 3, in this embodiment, the cloud application client can obtain the position information of the application screen of the target cloud application in the cloud application window. In practical applications, the cloud application client can obtain the required position information by calling the specified data collection interface provided by the cloud application server. For example, if the cloud application uses the JAVA framework, the data collection interface here can be a JS interface. It should be understood that although the cloud application client is not connected to the cloud application server in this embodiment, it still has the permission to access the relevant interfaces provided by the cloud application server. As mentioned above, in the cloud desktop, the access to the cloud application can be initiated through a browser or a soft terminal. Therefore, the position information obtained here can be used to describe the coordinate position of the application screen in the browser window or the soft terminal window. In practical applications, the application screen can fill the display window where it is located, or it can also occupy only a part of the window area.

[0067] After that, the cloud application client can transmit the obtained position information to the cloud desktop protocol server. Here, the cloud application client can transmit the position information to the second transmission module in the cloud desktop protocol server through the first transmission module deployed in it to achieve the transparent transmission of the position information.

[0068] In this embodiment, an application window manager can be deployed in the cloud desktop protocol server. On the one hand, the application window manager can obtain the position information of the application screen of the target cloud application provided by the cloud application client in the cloud application window; on the other hand, it can also obtain the position relationship between the cloud application window and other display windows in the cloud desktop.

[0069] An exemplary solution for obtaining the position relationship can be: using the application window manager to call the specified interface to capture the coordinate information and display order of each display window in the cloud desktop; determining the position relationship between each display window according to the coordinate information and display order. Since the cloud application window is one of the display windows in the cloud desktop, the application window manager will also obtain the coordinate information and display order of the cloud application window in the desktop image. In this way, the application window manager has sufficient reference data to determine the position relationship between the cloud application window and other display windows in the cloud desktop. In practical applications, the application window manager can call the specified interface provided by the operating system to capture the coordinate information and display order of each display window in the cloud desktop. For example, for a cloud desktop using the windows operating system, the application window manager can call the WinEventHook interface to obtain the coordinate information and display order of each display window in the cloud desktop. Among them, the display order is used to reflect the order of the display windows in the Z-order. The display window with a higher display order may block the display window with a lower display order.

[0070] On this basis, the application window manager can calculate the occlusion information corresponding to the application screen according to the position information and the positional relationship; it can also transmit the position information and the occlusion information to the cloud desktop protocol client.

[0071] For the cloud desktop protocol client, based on the cloud desktop data stream and the undecoded data stream, the target cloud application can be displayed in the cloud desktop according to the received position information and occlusion information.

[0072] An exemplary rendering scheme can be: according to the occlusion information, crop the application screen decoded from the undecoded data stream; according to the position information, splice the cropped application screen and the desktop image of the cloud desktop; display the spliced screen to display the target cloud application in the cloud desktop according to the occlusion information. In practical applications, since the application screen is not decoded in the cloud desktop protocol server, therefore, the display area of the application screen in the cloud application window included in the desktop image can be displayed as a specified pattern, and the specified pattern includes a pure white pattern, a pure black pattern or a mosaic pattern.

[0073] Figure 5 This is a schematic diagram of the rendering result of a cloud desktop provided by an exemplary embodiment of the present application. Refer to Figure 5 , according to the occlusion information, the occluded part in the cloud application screen can be cropped off, and then the remaining part of the application screen after cropping is spliced into the cloud application window included in the desktop image according to the position information, and finally the rendering result as shown in Figure 5 is generated.

[0074] It is worth noting that in practical applications, the application screen of the cloud application can fill the cloud application window, so that the user will not distinguish between local applications and cloud applications in terms of visual, auditory, tactile and other interaction experiences, thus better improving the user experience.

[0075] Accordingly, in this embodiment, the occlusion information corresponding to the application screen can be accurately calculated and provided to the cloud desktop protocol client in the cloud desktop terminal for the cloud desktop protocol client to accurately render the application screen of its target cloud application in the desktop image of the cloud desktop, thereby ensuring the display accuracy of the cloud application in the cloud desktop.

[0076] Figure 6 This is a schematic flowchart of a method for accessing a cloud application in a cloud desktop provided by another exemplary embodiment of the present application, and this method is applicable to a cloud desktop server. Refer to Figure 6 , a cloud desktop protocol server and a cloud application client are deployed in the cloud desktop server, and the method includes:

[0077] Step 600, in response to an access instruction for a target cloud application occurring in the cloud desktop, use the cloud application client to obtain the authentication information corresponding to the target cloud application;

[0078] Step 601: Transmit the authentication information to the cloud application connection establishment module deployed in the cloud desktop terminal to trigger the cloud application connection establishment module to establish a connection with the cloud application server where the target cloud application is located based on the authentication information and receive the undecoded data stream corresponding to the target cloud application from the cloud application server;

[0079] Step 602: Use the cloud desktop protocol server to transmit the cloud desktop data stream to the cloud desktop protocol client deployed in the cloud desktop terminal, so that the cloud desktop protocol client can display the target cloud application in the cloud desktop based on the cloud desktop data stream and the undecoded data stream received from the cloud application connection establishment module.

[0080] In an optional embodiment, the method may further include:

[0081] If it is determined that the cloud application connection establishment module is not deployed in the cloud desktop terminal or the connection between the cloud application connection establishment module and the cloud application server fails, use the cloud application client to establish a connection with the cloud application server based on the authentication information and receive the undecoded data stream corresponding to the target cloud application from the cloud application server;
