aiohttp中的websocket是一种异步实现的方式,可以实现实时向客户端推送最新的数据。在使用aiohttp的websocket时,可以通过以下代码来处理websocket连接:
```python
async def websocket_handler(request):
ws = web.WebSocketResponse()
await ws.prepare(request) # 等待websocket连接
async for msg in ws:
if msg.type == aiohttp.WSMsgType.TEXT:
if msg.data == 'close':
await ws.close()
else:
await ws.send_str(msg.data + '/answer')
elif msg.type == aiohttp.WSMsgType.ERROR:
print('ws connection closed with exception %s' % ws.exception())
print('websocket connection closed')
return ws
```
这段代码会等待websocket连接,并在接收到消息时进行处理。如果收到的消息是文本类型,可以根据具体的业务逻辑进行处理,比如发送回复消息。如果收到的消息类型是错误,可以进行相应的处理。最后,当websocket连接关闭时,会打印相应的信息并返回websocket对象。\[2\]
