WebSocketBadStatusException raised when connecting to webSocketDebuggerUrl in Chrome 108+

[realwumbl3]

When using PyChrome to connect to a tab's "webSocketDebuggerUrl" in Chrome 108 or newer, the following error is raised: "websocket._exceptions.WebSocketBadStatusException: Handshake status 403 Forbidden".

Seems to be related to Chrome checking the Origin of the incoming request. The recommended fix seems to be to suppress the header entirely: https://bugs.chromium.org/p/chromium/issues/detail?id=1422444#c5

I added an extra kwarg suppress_origin=True and that fixed the issue.

pychrome/pychrome/tab.py

Line 208 in c6c755b

self._ws = websocket.create_connection(self._websocket_url, enable_multithread=True)

I tried it and that worked! Thanks and good job! 💖

suppress_origin=True

This fix worked. Can you raise the PR for this?

version(0.2.4) I'm using has this suppress_origin=True and still not working

independent of any port I use.

chrome version: 117.0.5938.63

still not working

start chrome with one of

--remote-allow-origins=http://localhost:5222
--remote-allow-origins=*

chrome will print this to stderr

[ERROR:devtools_http_handler.cc(768)] Rejected an incoming WebSocket connection from the http://localhost:5222 origin. Use the command line flag --remote-allow-origins=http://localhost:5222 to allow connections from this origin or --remote-allow-origins=* to allow all origins.
