Detailed Description
The embodiment of the application is used for solving the problems of troublesome configuration and occupied performance of the prior art that a client is connected with a plurality of network elements WebSocket by providing a method and a system for unifying access gateways based on WebSocket.
According to the technical scheme in the embodiment of the application, the overall thought is as follows: the unified access gateway based on the WebSocket mainly comprises three parts of unified access points, webSocket connection optimization and protocol design optimization. The unified access point mainly aims at the client, when various gateways acquire various different service data, the connection protocol and the authentication problem during connection are not needed to be considered, the unified access point is only required to be developed according to the requirements of the transit gateway, and meanwhile, the connection of the transit gateway is only required, so that the capability of service development is realized. WebSocket connection optimization is two-way, namely, a server side is aimed at, and a client side is aimed at: aiming at the service end, N clients are originally arranged, the pressure to be born by the service end is N connections, and after the transit gateway is arranged, only 1 connection of the transit gateway is born, and the connection optimization is changed from N connections to 1 connection; for the aspect of the client, if there are M WebSocket servers, the client needs to create M WebSocket clients, and if there are transit gateways, only 1 connection is needed to be performed for the transit gateway, and the connection optimization is optimized to be 1 by M. Protocol design optimization means that the message from the client side to the message from the server side is converted; when the client transmits the message, the client transmits the message in a format required by a transfer gateway, wherein the format mainly comprises a receiver and a transmitted message body, the transfer gateway analyzes the receiver, encapsulates the message into the sender and the transmitted message body, a server network element analyzes the message, and returns the message as the receiver and the service result as the message body according to the received sender ID after the service is processed. In the process, the decoupling of the client and the server is also realized, the client does not need to care about the state of the current service network element any more, and only the network element name needing to be docked is indicated in the protocol, and the gateway is transferred to be responsible for docking and returning the response message.
In order to better understand the above technical solutions, the following detailed description will refer to the accompanying drawings and specific embodiments.

The technology is designed and realized on the basis of WebSocket and the proxy thought of Nginx. WebSocket is a protocol that performs full duplex communication over a single TCP connection, which makes the exchange of data between a client and a server simpler, allowing the server to push data to the client on its own initiative. In the WebSocket API, the client and the server only need to complete one handshake, and can directly create persistent connection between the two and perform bidirectional data transmission. Nginx is an HTTP server, and has a great effect of matching according to Url, and proxy real server, so as to realize hiding and unifying interfaces outside a server heap.
The invention realizes that the access points of the client WebSocket are unified as the transit gateway by the unified entry method, and solves the problems of troublesome configuration and occupation performance of the client connected with a plurality of network elements WebSocket. According to the invention, the transit gateway and other service end network elements adopt a connection mode, and the client is not connected with each network element any more, so that the problem of occupying excessive connection and affecting the performance is solved; the access of the transit gateway also ensures that the client does not need to care about the states and the connection modes of other network elements, thereby realizing the decoupling of the client and other network elements.
