我正在学习python中的一些异步/等待,我想尝试它,但是 我在尝试连接到chatango时遇到此错误websocket,我不知道是什么意思。aiohttp.client_exceptions.ClientResponseError:400,message ='无效常量字符串'
我使用python 3.6.1和2.2.3 aiohttp
这是我的代码:
import asyncio
import aiohttp
msgs = []
async def main():
async with aiohttp.ClientSession() as session:
async with session.ws_connect("ws://s12.chatango.com:8081/") as ws:
for msg in ws:
msgs.append(msg)
print(msg)
loop = asyncio.get_event_loop()
loop.run_until_complete(main())
loop.close()
完全回溯:
Traceback (most recent call last):
File "C:\Program Files\Python36\lib\site-packages\aiohttp\client_reqrep.py", line 559, in start
(message, payload) = yield from self._protocol.read()
File "C:\Program Files\Python36\lib\site-packages\aiohttp\streams.py", line 509, in read
yield from self._waiter
File "C:\Program Files\Python36\lib\site-packages\aiohttp\client_proto.py", line 165, in data_received
messages, upgraded, tail = self._parser.feed_data(data)

aiohttp.http_exceptions.BadHttpMessage: 400, message='invalid constant string'
The above exception was the direct cause of the following exception:

是否为''ws://s12.chatango.com:8081 /“'是正确的?我在这个问题上读到并得出结论,也许你的资源是错误的... –
