根因分析

客户端未发送关闭帧即关闭套接字；服务端循环继续调用 receive/send 而未捕获 WebSocketDisconnect。

English

Client closed the socket without a close frame; server loop keeps calling receive/send without catching WebSocketDisconnect.

解决方案

  1. 93% 成功率 
    try:
    while True:
        msg = await ws.receive_text()
        await ws.send_text(msg)
except WebSocketDisconnect:
    pass
  2. 88% 成功率 
    Use ws.iter_text() and break on disconnect; send a ping interval for liveness.

无效尝试

常见但无效的做法:

  1. 70% 失败

    Hides real errors and leaks sockets; CPU spins on reconnect storms.

  2. 75% 失败

    close() on a dead socket raises again.
