Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be appreciated that reference throughout this specification to "an embodiment" or "one embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrase "in an embodiment" or "in one embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In the description of the present invention, it is to be understood that the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the term "connected" is to be interpreted broadly, e.g. as either directly or indirectly through intervening media. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The inventor of the application finds that, through a lot of creative labor, a HyperText Transfer Protocol (HTTP) request application sends a request message to a server at a client, and a websocket can realize that the server actively pushes data to the client in a long connection mode, so that data exchange between the client and a server becomes simpler. The message queue can effectively avoid the problem of program abnormity caused by network fluctuation or message sending failure in an asynchronous mode. Based on this, the present invention has been proposed.
The communication method for making a heterogeneous network based on a movie cloud according to the present invention is described below with reference to fig. 1.
As shown in fig. 1, the communication method for manufacturing a heterogeneous network based on a movie cloud of the present invention includes:
s1: and acquiring a user request sent by a client.
Specifically, the movie cloud production heterogeneous network comprises a client, a service system and a distributed node machine. Wherein the client may be a browser end. And the user sends a user request to the service system through the client. The user request may be an HTTP request, which is used to render a certain file, upload or download a certain file, compress or package a certain file, or the like.
S2: and generating corresponding task parameters according to the user request.
Specifically, after receiving the user request, the service system first verifies whether the user request is incorrect, for example, whether a request address in the user request exists, or the like. If the user requests the error, feeding back request error information to the client, for example, the requested address does not exist, and then ending the process; and if the user request is correct, feeding back confirmation information to the user.
After verifying that the user request is correct, the service system may initiate a kernel program deployed on the distributed node machine based on a Remote Procedure Call (RPC) framework Remote command. The RPC framework can callout remote functions as if it were calling a local function. Using the RPC framework requires Call ID mapping, serialization and deserialization and network transmission. In a local call, the body of the function is specified directly by a function pointer. However, in remote calls, the function pointer is not used because the address spaces of the two processes are completely different. Therefore, in RPC, all functions must have their own ID. This ID is uniquely determined in all processes. The client must attach this ID when making remote procedure calls. Then, a corresponding table needs to be maintained at the client and the server, respectively. The tables of both need not be identical, but the Call IDs corresponding to the same function need to be identical. When the client needs to be remotely called, the corresponding table needs to be inquired, the corresponding Call ID is found out and then is transmitted to the server, the server determines the function to be called by the client through table look-up, and then the code of the corresponding function is executed. In local calling, it is only necessary to push the parameter to the stack and then let the function read from the stack. However, when the remote process is called, the client and the server are different processes, and parameters cannot be transmitted through the memory. Even sometimes the client and server use different languages. At this time, the client is required to convert the parameters into a byte stream, and then convert the byte stream into a format which can be read by the client after the parameters are transmitted to the server. This process is called serialization and deserialization. Similarly, the value returned from the server also requires a serialization deserialization process. Remote invocation is often used over a network, with the client and server connected through the network. All data needs to be transported over the network and therefore a network transport layer is required. The network transmission layer needs to transmit the Call ID and the serialized parameter byte stream to the server, and then transmit the serialized Call result back to the client. Both of these can be used as the transport layer as long as they can be accomplished. Thus, the protocol used is not limited in nature and the transfer can be accomplished.
In this embodiment, after the core program is started, the core program requests the service system to acquire the required task parameters in a synchronous manner based on the HTTP protocol interface. And the service system generates corresponding task parameters according to the user request. Specifically, the service system extracts request content information in a user request, for example, when a user requests to render a certain file, the requested rendering file and rendering mode information selected by the user need to be extracted. The rendering mode is preset by the service system and is selected by a user, for example, the service system provides a rendering mode X, a rendering mode Y and a rendering mode Z, and the user can select one of the rendering modes from the rendering mode X, the rendering mode Y and the rendering mode Z through the client. And when the user selects the rendering mode, the service system can acquire the corresponding rendering parameters through the rendering mode selected by the user. The business system takes the request rendering file and the rendering parameters as task parameters,
s3: and sending the task parameters to the distributed node machine so that the distributed node machine executes corresponding tasks according to the task parameters.
Specifically, when the distributed node machine receives the task parameters, the distributed node machine executes corresponding tasks according to the task parameters, for example, when a user requests to render a requested rendering file, the distributed node machine renders the requested rendering file according to the rendering parameters. And when the distributed node machine executes the corresponding task, the task execution condition information is stored.
S4: and receiving task execution condition information fed back by the distributed node machine through the asynchronous message queue.
Specifically, the distributed node machine receives task execution condition information fed back by the distributed node machine through the asynchronous message queue. The distributed node machine sends messages to the queue, the service system obtains the messages from the queue, the distributed node machine and the service system are decoupled, and when the distributed node machine sends the messages, the asynchronous mode is achieved without the response of the service system. The embodiment can ensure that the problem of abnormal operation of the core program caused by failure of message sending or failure of synchronous messages due to network fluctuation can not occur in the operation process of the core program by the mode of feeding back the information by the asynchronous message queue, thereby ensuring the operation stability of the core program.
S5: and establishing long connection with the client, feeding back the client according to the task execution condition information, and updating the task state.
Specifically, WebSocket is a protocol of HTML5, HTTP is not supported for persistent connections. Websocket only needs to pass through one HTTP request, thus avoiding the non-stateness of HTTP and realizing continuous information transmission. In this embodiment, the service system establishes a long connection with the client through a long connection manner of the WebSocket, feeds back to the client according to the task execution condition information and updates the task state, so that data synchronization under the conditions that the client foreground is not started and the like can be solved, the client foreground does not need to return after receiving the message, and the communication efficiency can be greatly improved.
And after the service system finishes the content request of the user of the client, releasing the node resources and stopping using the scheduling server and the file transmission server.
