Article Introduction：The mod_proxy_wstunnel module is the key to Apache's handling of WebSocket connections, which ensures that requests are correctly forwarded to the backend and the connection is constantly opened. 1. First enable the mod_proxy and mod_proxy_wstunnel modules, and restart the Apache service; 2. Use the ws:// or wss:// protocol when configuring VirtualHost to ensure path matching; 3. Add the RequestHeader to set Upgrade and Connection headers to support protocol switching; 4. Configure valid certificates and point to the wss:// address when using SSL/TLS; 5. Test through browser console, wscat and other tools

Article Introduction：Create a WebSocket connection with newWebSocket('wss://example.com/socket'); 2. Listen onopen, onmessage, onerror and onclose events to handle the connection life cycle; 3. Send data through socket.send(), and use JSON.stringify() when sending objects; 4. Use JSON.parse() to parse and process data when receiving messages, and parse errors need to be captured; 5. You can call socket.close() to manually close the connection; 6. Implement the reconnect mechanism to deal with network interruptions, and it is recommended to adopt an exponential backoff strategy; 7. The server needs to support Web

Article Introduction：To establish a WebSocket connection using JavaScript, you first need to create a WebSocket object and provide the correct URL. 1. Use the WebSocket constructor and pass in the server URL (starting with ws:// or wss://); 2. Listen to open, message, error and close events to handle connection status; 3. Handle disconnection and common problems in actual scenarios; 4. Use tool testing to implement logic to ensure reliability. The entire process needs to pay attention to security protocol selection, event handling, error and shutdown response, and network environment restrictions, and implement automatic reconnection mechanism when necessary.

Article Introduction：WebSockets is a key technology for real-time applications, providing persistent two-way communications that are more efficient than polling. 1. It is an HTML5 protocol, allowing clients and servers to send data to each other at any time; 2. When using it, the front-end establishes connections and listens to events through several lines of code, and the back-end needs to cooperate with a library that supports WebSocket; 3. Application scenarios include chat rooms, stock updates, online games, collaborative documents, etc.; 4. When using it, pay attention to the cross-domain, reconnection mechanism, and message formats unified into JSON and encryption protocol wss://.

Article Introduction：How to implement front-end real-time communication using WebSockets? 1. Establish a connection: Use newWebSocket('wss://address') to create an instance and listen to the onopen/onmessage/onerror/onclose event; 2. Handle message format: send and receive JSON strings and parse and serialize them through try-catch, and agree to distinguish message types; 3. Response to interrupt reconnection: Listen to the onclose/onerror event to set a 5-second interval to automatically reconnect, limit the maximum number of times such as 5 times, or use Socket.io and other libraries to manage state; 4. Performance optimization: Avoid high-frequency big data transmission, call socket.c when the page is closed

Article Introduction：1. The key to real-time data synchronization using H5WebSockets is to establish a stable two-way communication channel. 2. Ensure stable connection by creating WebSocket instances and processing open, message, error and close events. 3. Ensure secure transmission by using wss:// protocol. 4. Send and receive structured data using JSON format and verify the data format to prevent crashes. 5. Last-write-wins, OT or CRDT policies can be used to manage states and conflicts. 6. To avoid data loss, the server should cache recent messages and playback when the client reconnects. 7. Pay attention to message sequence control and add a unique ID and serial number to each message. 8. Finally, it must be true.

Article Introduction：SSE is suitable for one-way push of servers, and WebSocket is suitable for two-way real-time communication. SSE is based on the HTTP protocol and is implemented through EventSource API, supporting automatic reconnection, and is suitable for news push and other scenarios; WebSocket is a full duplex protocol, and requires connection establishment through ws:// or wss://, which is suitable for high-real-time scenarios such as online games and instant messaging. The main differences between the two include communication direction, protocol basis, compatibility, connection management and resource consumption; when choosing, it should be determined based on factors such as whether two-way communication is needed, delay requirements, and development complexity.

Article Introduction：H5WebSockets is a full-duplex communication protocol provided by HTML5, which allows the browser to establish a persistent connection with the server and realizes low-latency bidirectional data transmission. 1. It continuously interacts through a single TCP connection, avoiding the high latency and waste of resources caused by traditional HTTP polling; 2. It is suitable for online chat, real-time market, collaborative editing, game synchronization and other scenarios that require instant push; 3. When using it, the front-end creates connections and listens to events such as onopen, onmessage, onclose and onerror, and the back-end can use Node.js or Python to build services; 4. Notes include priority use of encryption protocols wss:// and processing network

Article Introduction：WebSocket is a network protocol that implements full duplex communication between browsers and servers. Compared with traditional polling methods, it has lower latency, less bandwidth consumption and stronger real-time performance. Its core advantages include: 1. Reduce latency: no need to establish frequent connections; 2. Reduce bandwidth usage: avoid duplicate HTTP header information; 3. Strong real-time: The server can actively push messages. The front-end realizes communication by creating WebSocket instances and listening to open, message, error, and close events; the back-end such as Node.js can use the WS library to build services. Pay attention to when using: 1. Handle connection failure and downgrade scheme; 2. Add automatic reconnection mechanism; 3. Use wss encryption to ensure security; 4. Unify message grid

Article Introduction：To establish real-time communication through HTML5WebSocket API, the following steps must be followed: 1. Create a connection using the URL of the ws:// or wss:// protocol; 2. Handle open, message, error, and close events; 3. Use the send() method to send data after the connection is established; 4. Use the close() method to close the connection gracefully. First make sure that the server supports WebSocket and is configured correctly, initializes the connection with the correct protocol, then add listeners to each event in response to connection status changes and data reception, and then send data after the open event is triggered. You can send text, JSON or binary content, and finally call close at the end of the communication.
