The cloud application client generally runs on a terminal device of a user, the terminal device is connected with a keyboard, a mouse, a handle and other human input devices, and the user controls the use of the cloud application client by operating the human input devices connected with the terminal device.
The operation of the user on the cloud application client generates operation data and transmits the operation data to the network proxy server, and then the network proxy server transmits the operation data of the cloud application client to the cloud application server.
The cloud application server is provided with a preset server management component for managing a data processing process performed on the server, wherein the preset server management component is used for identifying operation data and distributing the operation data to a corresponding cloud application process.

Specifically, the cloud application processes in the embodiment of the application are all operated in an isolation environment of the cloud application server, and different cloud application processes are isolated from each other and do not affect each other.
In an isolation environment where the cloud application process is located, an HID protocol stack and an HID driver stack exist and are used for providing an environment for simulating HID APIs. The cloud application process processes the operation data from the cloud application client by calling the simulated HID APIs in the isolation environment. Specifically, processing the operation data includes processing device input data in the operation data. The method has the advantages that the HID APIs are simulated in the isolation environment, and the simulated HID APIs in the same isolation environment with the process can be directly called by the cloud application process when data processing is needed, and system calling is not needed. Simulated HID APIs exist in the isolation environment where each cloud application process is located, and the cloud application processes are not connected with each other and not influenced with each other. In the embodiment of the application, taking a cloud game as an example, the cloud game process adds device input data from a cloud game client on the basis of a game scene, and further renders to obtain cloud game video data.
And the cloud application server compresses the processed video data and feeds the compressed video data back to the corresponding cloud application client. Further, the cloud application client of the user decompresses the video data, and the real-time video of the cloud application can be displayed on the terminal device connected with the client.

In addition, various input modes such as a keyboard, a mouse, a touch screen, a microphone, a camera and the like can be provided, and input can be adjusted as required. Meanwhile, the equipment often has a plurality of output modes, such as a telephone receiver, a display screen and the like, and can be adjusted according to needs;

Meanwhile, the device integrates a plurality of software and hardware, and the function is more and more powerful.
Further, as disclosed in the present application, in a method for implementing a cloud application, the various types of data may be stored in a blockchain.
An embodiment of the present application provides a method for implementing a cloud application, and as shown in fig. 2, the method includes:
step S201, responding to operation data of a client, determining a corresponding cloud application process based on first identification information in the operation data, wherein the cloud application process runs in a sandbox, and the sandbox has a unique corresponding cloud application process.
The cloud application in the embodiment of the application may be a cloud game, and the operation data of the client may be operation data of the cloud game client. The cloud game client sends the operation data to the cloud game server, specifically, the operation data sent to the cloud game server by the cloud game client needs to pass through a network proxy server, namely, the cloud game client sends the operation data to the network proxy server, and the network proxy server forwards the received operation data to the corresponding cloud game client.
The operation data comprises first identification information of the client, device attribute information of the client and specific device input data.
The cloud game server responds to the operation data from the client and analyzes the operation data by adopting the server management component to obtain first identification information of the client, equipment attribute information of the client and specific equipment input data. Further, because the identification information of the cloud game client is unique, the server management component can determine the cloud game process corresponding to the client based on the first identification information in the operation data. Wherein the cloud game process is run in a sandbox isolated environment of the cloud game server. Each sandbox has a unique cloud game process, and different cloud game processes run in different sandboxes, so that the purpose of mutual process isolation is achieved.
Step S202, intercepting and calling the behavior action of the human input device application programming interface (HID API), calling the simulated HID APIs corresponding to the cloud application process to process device input data in the operation data, and obtaining video data.
In the embodiment of the application, the cloud game server does not have HID virtual hardware and does not have a real HID API related interface, so that before the cloud game process calls the simulated HID APIs, the behavior of calling the real HID APIs by the process needs to be intercepted, in other words, the behavior of calling the system is intercepted, and the delay caused by calling the system is avoided.
After the intercepting process calls the behavior action of the real HID APIs, calling a functional interface for simulating the HID APIs in a sandbox environment where the cloud game process is located, processing equipment input data in operation data, and rendering and generating a cloud game video picture on the basis of a cloud game scene.
The functional interfaces for simulating the HID APIs specifically comprise 3 types of interfaces for simulating the HID APIs: a discovery and setup interface, a protocol capability resolution interface, and a read and write interface. And the cloud game process calls the simulated discovery and setting interface, the simulated protocol capability analysis interface and the simulated reading and writing interface to realize the function of processing the equipment input data of the human input equipment. And the cloud game process acquires the equipment input data and the corresponding equipment attribute information from the simulated HID APIs, and realizes the processing process of the equipment input data under the condition of not carrying out system call.
Specifically, the video pictures of the cloud game are expressed in the form of data, namely, the video data is obtained by processing the input data of the equipment.
And step S203, feeding back the video data to the client.
The cloud game server feeds the processed video data back to the corresponding cloud game client, and specifically, the video data comprises cloud game video data obtained by compressing cloud game video pictures. After the user receives the video data fed back by the cloud game server at the client, the user decompresses the video data to view a real-time game picture.
The implementation method of the cloud application, provided by the embodiment of the application, comprises the steps of responding to operation data of a client, determining a corresponding cloud application process based on first identification information in the operation data, enabling the cloud application process to run in a sandbox, enabling the sandbox to have the unique corresponding cloud application process, intercepting behavior actions of calling human input device application programming interfaces (HID APIs), calling simulated HID APIs corresponding to the cloud application process to process device input data in the operation data to obtain video data, and feeding the video data back to the client.
According to the application, the functions of simulating the HID APIs are realized in the isolation environment of the cloud server, each cloud application process can independently complete the calling of the simulated HID APIs, the system resource anthropological input equipment HID virtual hardware is not needed in the realization of the cloud application, the delay caused by the system calling of the system resource in the existing cloud application realization process is avoided, the data processing process is completely carried out in the isolation environment, a plurality of cloud applications can be simultaneously operated on the cloud server, and better experience is brought to a user.
In the embodiment of the present application, another cloud application implementation method is provided, and as shown in fig. 3, the method includes:
step S301, responding to the operation request of the client, and analyzing the operation request by using a preset server management component to obtain second identification information.
The cloud application in the embodiment of the application may be a cloud game, and the operation request of the client may be an operation request of a cloud game client. Specifically, as shown in fig. 4, the operation request sent by the cloud game client to the cloud game server needs to pass through the network proxy server, that is, the cloud game client sends the operation request to the network proxy server, and the network proxy server forwards the received operation request to the corresponding cloud game client.
Through the process, the cloud game client side and the cloud game server are connected, and further the cloud game server responds to the operation request of the cloud game client side.
The cloud game server is provided with a preset server management component, and the server management component can realize various server management functions. For example, the server management component may parse the operation request of the client, and obtain the identification information of the client, that is, the second identification information, through parsing. The identification information is used to distinguish client IDs from different game clients, and it should be noted that different cloud game clients have different client IDs, and each client has only a unique client ID.
Step S302, storing the second identification information into the server management component, and creating a corresponding cloud application process in the sandbox by adopting the server management component based on the second identification information.
After the server management component analyzes the operation request to obtain the second identification information, the second identification information obtained through analysis is stored in the distinguishing device of the server management component, so that the operation data from different cloud game clients can be distinguished through the distinguishing device of the server management component based on the identification information, and the operation data from the different cloud game clients are ensured not to be influenced.
The cloud application in the embodiment of the application may be a cloud game, the operation request of the client may be an operation request of a cloud game client, and correspondingly, the cloud application process may also be a cloud game process. As shown in FIG. 5, cloud gaming processes are run in sandboxed environments that are isolated from each other. When the cloud game server responds to the running request of the cloud game client, the server management component creates a corresponding cloud game process of the client in the empty sandbox based on the second identification information of the client.
Step S303, responding to the operation data of the client, determining a corresponding cloud application process based on the first identification information in the operation data, wherein the cloud application process runs in a sandbox, and the sandbox has a unique corresponding cloud application process.
When the cloud game client is connected with the cloud game server, operation data generated by operation of a user on the client is sent to the cloud game server through the network service. The operation data comprises identification information of the client, equipment attribute information of the client and specific equipment input data.
The cloud game server responds to the operation data from the client, and the server management component is adopted to determine the cloud game process corresponding to the client based on the first identification information in the operation data. The cloud application process runs in an isolation environment, a unique cloud game process exists in each sandbox, and different cloud game processes run in different sandboxes, so that the purpose of mutual isolation of the processes is achieved.
In a preferred embodiment of the present application, determining a corresponding cloud application process based on first identification information in operation data includes:
and analyzing the operation data by adopting a preset server management assembly to obtain first identification information and equipment input data.
And matching the first identification information with at least one piece of stored second identification information, and if a matching item exists, taking the cloud application process corresponding to the matching item as a final cloud application process.
The server management component analyzes the operation data to obtain identification information of the cloud game client, namely first identification information. The identification information is used to distinguish client IDs from different game clients, and it should be noted that different cloud game clients have different client IDs, and each client has only a unique client ID.
In addition, the server management component can analyze the operation data to obtain the device attribute information of the client and specific device input data.
The device attribute of the client is a device attribute of a human input device itself used in connection with the client, for example, a device attribute of a mouse, a keyboard, a touch screen, or a handle. Based on the device attributes of the human input device, different functions of different devices can be clarified, specific device input data can be processed conveniently, and the corresponding relation between the human input device and the device input data can be confirmed. It should be noted that, the embodiment of the present application does not set any limit to the specific type of the anthropological input device.
For the application of the cloud game, control operation data generated by a user operating on a client, input operation data, or other data generated by an operation process needing to be completed by means of a human input device may be referred to as device input data. The implementation steps of the cloud game comprise the steps of transmitting equipment input data from a client to a cloud game server, and generating a game video picture in the cloud game server by combining with a cloud game process, so that the generated video picture is fed back to the client to be displayed.
And the server management component matches first identification information obtained by analyzing the operation data with second identification information stored in the partition device of the server management component, wherein the second identification information is identification information obtained by analyzing the operation request by the server management component. In particular, the step of distinguishing the identification information from the client is also done by the distinguishing means of the server management component.
And if the second identification information is matched with the first identification information, taking the cloud game process created based on the second identification information as the cloud game process corresponding to the first identification information, namely the final cloud game process. Therefore, the corresponding cloud game process can be determined based on the first identification information in the operation data.

the method comprises the steps of simulating a discovery and setting interface of the HID APIs in a sandbox corresponding to a cloud application process, simulating a protocol analysis capability interface of the HID APIs in a protocol stack of the human input equipment, and simulating a reading and writing interface of the HID APIs in a driver stack of the human input equipment.

And simulating a reading and writing interface of the HID APIs in a human input device driver stack corresponding to the cloud game process, so that the cloud game process can successfully call the reading and writing interface of the simulated HID APIs.
And the cloud game process calls the simulated discovery and setting interface, the simulated protocol capability analysis interface and the simulated reading and writing interface to realize the function of processing the equipment input data of the human input equipment. The cloud game process acquires the equipment input data and the corresponding equipment attribute information from the simulated HID APIs, and the processing process of the equipment input data is realized under the condition of not carrying out system call.
The cloud game server renders a cloud game scene based on the processed device input data to obtain a cloud game video picture, and specifically, the game video picture is represented in a data form to obtain video data.
And step S306, feeding back the video data to the client.
And the cloud game server feeds back the processed video data to the corresponding cloud game client, wherein the video data specifically comprises cloud game video data obtained by compressing cloud game video pictures. After the user receives the video data fed back by the cloud game server at the client, the video data is decompressed, and then the real-time game pictures can be watched in the display device connected with the client.
