解决方案

  1. 90% 成功率 Handle the close event gracefully and clean up resources. 
    async def websocket_endpoint(websocket):
    await websocket.accept()
    try:
        while True:
            data = await websocket.receive_text()
            await websocket.send_text(f"Echo: {data}")
    except websockets.exceptions.ConnectionClosed:
        print('Connection closed')
  2. 85% 成功率 Implement reconnection logic with exponential backoff. 
    import asyncio
async def connect():
    while True:
        try:
            async with websockets.connect('ws://...') as ws:
                await ws.send('hello')
        except websockets.exceptions.ConnectionClosed:
            await asyncio.sleep(1)

无效尝试

常见但无效的做法:

  1. Assuming it's an error and trying to reconnect indefinitely. 60% 失败

    Normal closure is not an error; reconnecting without reason is wasteful.

  2. Ignoring the close event and continuing to send messages. 90% 失败

    The connection is closed; sending messages will raise another error.
