Online Websocket Interface Testing

1. WebSocket is a protocol that enables full-duplex communication over a single TCP connection, allowing for real-time, bidirectional communication between clients and servers.

2. WebSocket uses a persistent connection to maintain a long-lived link between the client and server, enabling real-time data transmission and reception.

3. WebSocket features bidirectional communication, high real-time performance, support for binary data, and low control overhead.

4. The WebSocket protocol identifier is ‘ws’; if encrypted, it is ‘wss’. The server address is the URL.

5. WebSocket is commonly used in scenarios such as real-time chat, real-time collaboration, real-time data push, multiplayer online games, and online customer service.
