requests.get('https://github.com', verify=True) is fine
requests.get('https://c.pcs.baidu.com/rest/2.0/pcs/file', verify=True) produces error

比较有用的更新：我现在测试，墙内也可以用了。
细节：用红帽的网站又搭了一个授权网页，貌似用https访问，不会被墙。
反映授权出错的童鞋，可以尝试一下最新版。

Hmm, strange. Now this SSLError is reported again. No idea why this happens (it shouldn't). Anyway, I think it can be worked-around by setting verify = False.

Maybe it's due to the requests library being too old? as stated here:
https://stackoverflow.com/questions/18999517/python-requests-certificate-verify-failed

See if upgrading the requests library solves the problem?

What i mean by those sentences is: The latest version of the script works even you are confined by the famous Great Fire Wall.

[larryxiao]

by upgrading requests to 2.2.1 the problem remains
baidu's cert is valid indeed ...
thanks!

[houtianze]

so strange... yah, i also agree that Baidu's cert shouldn't have a problem.
i will run the script to do some up/download and see if i can reproduce first. i actually have uploaded a large number of files, so far, never encountered this.

Maybe it's Python Requests library's problem, as discussed here:
https://stackoverflow.com/questions/10667960/python-requests-throwing-up-sslerror

Since I really can't confirm this, I just worked around it with verify = False. It should have resolved this SSL error.

[larryxiao]

Yes, I think that explains it well.
And I think this issue can be closed
BTW.
Thanks for writing this useful tool!
