Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing and exemplary embodiment:

[0040] Such as figure 1 Shown is a flow chart of a distributed state synchronization method in which HTTP and WebSocket cooperate in an embodiment of the present invention, and the specific steps include:

[0041] Step S1: WebSocket server cluster initialization, each WebSocket server node initializes and generates a concurrent hash table and heartbeat detection thread: deploys a WebSocket server cluster, configures the initial URL of the server cluster, and initializes and generates a concurrent hash table and heartbeat when each WebSocket server node in the cluster starts Detection thread; the initial URL of the server cluster includes the WSS protocol applicable to the browser end, the WSS protocol applicable to the APP end, and the WS protocol; the concurrent hash table adopts a Key-Value storage structure, including a session hash table session...

Abstract

The invention discloses an HTTP and WebSocket collaborative distributed state synchronization method which is characterized by comprising the following steps: step 1, initializing a WebSocket server cluster, step 2, reconstructing a URL of the WebSocket server cluster, step 3, allocating a WebSocket session to each client, step 4, detecting whether long connection is normal, step 5, determining aservice state change request. Step 6, calling a service server to process the request, and feeding back a result to the client, step 7, sending the request to the WebSocket server node, and step 8, closing the long connection. The WebSocket server is used for replacing an original client to send heartbeat detection, messages or external storage is not used, the effects of being simple in deployment and easy to expand are achieved, and meanwhile the using function requirements of different scenes are met.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a distributed state synchronization method in which HTTP and WebSocket cooperate. Background technique [0002] In real-time communication fields such as audio and video, screen sharing, etc., for efficient collaboration between users, a real-time status synchronization system is required, which is compatible with browsers and APPs. WebSocket uses persistent connections to realize instant messaging from the server to the client. However, when the client requests the server, the operation result cannot be sensed in real time due to the use of asynchronous messages, and the operation may be wrong. Using the WebSocket protocol alone requires an additional authentication mechanism. [0003] In terms of WebSocket long connection, the existing technology mostly uses the client to send heartbeat and can only send text, which needs to be implemented simultaneously by the clien...
