requests.post fail inside of django shell but not python shell

[paulfab]

When I execute :
requests.post("​https://slack.com/api/chat.postMessage", data= {"channel": "maison"})
it fails in the django shell (python manage.py shell) with the error :

InvalidCodepoint: Codepoint U+002A at position 1 of u'*' not allowed

but it doesnt fail in the python shell
So this tells me it is probable something Django related
It was working before, and the only thing I changed is that I updated the SSL certificate of my server

Thanks

complete trace of the error is :

You'll need to tell us where the issue is. I don't see anything obvious indicating that Django is at fault.

[paulfab]

Well
I execute the same line : requests.post("​​https://slack.com/api/chat.postMessage", data= {"channel": "maison"})
In both the django shell 'python manage.py shell' and the python shell 'python', and it only fails in the first one,
so this is django shell related

[Tim Graham]

Please tell us where the problem is rather than asking us to debug the issue. Looking at the traceback doesn't indicate why Django is at fault.

[Simon Charette]

manage.py shell uses iPython or bpython if available in your environment. Is it the case here?

Else it could be caused by some code your application monkey patches but as Tim pointed out nothing seems to indicate Django is at fault here.

[paulfab]

The fact is that my application is very simple there is no monkey patch. I just wanted to know in what sense django shell is different than python shell, ipython or bpython could be the reason, but it is not available on my system.

Maybe Django has nothing to do with that, but that is his way to handle https that broke my request.

Thanks anyway
