urllib2.HTTPError: HTTP Error 403

merkvilson

urllib2 no longer has any effect in Cinema 4D.
It is worth mentioning that I did not change anything in my code. It was working like a charm.
I doubt the latest windows update corrupted it.
Are there any solutions to bypass this limitation?

Hi could you share your code, without your code, it's hard to reproduce.
Cheers,

Code:

import c4d, urllib2, os

url = r"https://www.patreon.com/posts/24993001"

f = os.path.join(os.path.dirname(c4d.storage.GeGetStartupApplication()), "resource", "ssl", "cacert.pem")

urllib2.urlopen(url, cafile=f)

Error:

hello,

we did run a couple of test and seems that the "issue" is on Patreon side.

HTTP Error 403: Forbidden

We did try with other url, it work.
We did try adding header-agent or things like that, it failed.

They probably changed something on their server that doesn't allow to connect with python with default parameters.
You have to contact them in order to know what you have to do.

Cheers
Manuel
