我无法使用^{
import asyncio, ssl
import websockets
headers= {
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'en-US,en;q=0.9',
'Cache-Control': 'no-cache',
'Connection': 'Upgrade',
'Host': ...,
'Origin': ...,
'Pragma': 'no-cache',
'Upgrade': 'websocket',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36'
}
async def hello():
uri = ...
async with websockets.connect(ssl=0,
extra_headers=headers,
origin="*",
uri = uri) as websocket:
pass
asyncio.get_event_loop().run_until_complete(hello())
我得到以下例外情况:
Traceback (most recent call last):
File "C:\Users\AFMN\AppData\Local\Programs\Python\Python38-32\kr ws.py", line 30, in <module>
asyncio.get_event_loop().run_until_complete(hello())

raise InvalidStatusCode(status_code)
websockets.exceptions.InvalidStatusCode: server rejected WebSocket connection: HTTP 400
但问题是,我可以使用^{websocket
的代码:
import websocket, ssl
try:
import thread
except ImportError:
import _thread as thread
import time, msgpack
headers= {
'Accept-Encoding': 'gzip, deflate, br',
'Accept-Language': 'en-US,en;q=0.9',
'Cache-Control': 'no-cache',
'Connection': 'Upgrade',
'Host': ...,
'Origin': ...,
'Pragma': 'no-cache',
'Upgrade': 'websocket',
'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36'
}
def on_message(ws, message):
...
def on_error(ws, error):
...
def on_close(ws):
...
def on_open(ws):
...
if __name__ == "__main__":
websocket.enableTrace(True)
ws = websocket.WebSocketApp(...,
on_message = on_message,
on_error = on_error,
on_close = on_close,
header=headers,
subprotocols=["binary", "base64"])
ws.on_open = on_open
ws.run_forever(sslopt={"cert_reqs": ssl.CERT_NONE})
为什么我不能在第一个代码中连接到websocket,而我可以使用另一个模块连接到同一个websocket
如何使用第一个连接
你的网址是什么?看起来该服务器只支持TLS上的WebSocket,所以应该使用
wss://
而不是ws://
