python websocket 重连代码

Here is an example of how to implement WebSocket reconnection in Python using the websockets library:

  1. import asyncio
  2. import websockets
  3. async def connect():
  4. while True:
  5. try:
  6. async with websockets.connect('wss://example.com/ws') as websocket:
  7. # Your WebSocket code here
  8. await websocket.send('Hello, world!')
  9. response = await websocket.recv()
  10. except Exception as e:
  11. print(f'Connection error: {e}')
  12. finally:
  13. # Wait before attempting to reconnect
  14. await asyncio.sleep(5)
  15. asyncio.get_event_loop().run_until_complete(connect())

In this example, the connect() coroutine runs indefinitely and attempts to establish a WebSocket connection to 'wss://example.com/ws'. If a connection error occurs (such as a network issue or server outage), the exception is caught and the coroutine waits for 5 seconds before attempting to reconnect.

You can adjust the time interval between reconnection attempts by modifying the await asyncio.sleep(5) line. Additionally, you can customize the exception handling logic based on your specific use case.
