Google App Engine上的python请求不适用于HTTPS [英] python requests on Google App Engine not working for HTTPS

问题描述

我在Google App Engine上使用python-request，并且HTTPS无法按预期工作。我们来看一个例子：

pre $ 导入请求
requests.get（'https://www.digitalocean.com' ）


如果我在终端中执行它，这条线就完美了。响应是200 OK（没有重定向）。

但是，如果我在GAE上执行它，则会引发TooManyRedirects错误。
试图找出我使用allow_redirects = False执行的问题，我可以看到响应是指向相同url的重定向（301）！ （'位置'标题值为' https://www.digitalocean.com '）。这显然（当allow_redirect = True时）会一遍又一遍地发生，直到引发TooManyRedirects错误。

所以python-requests似乎不适用于HTTPS的GAE我已经测试了几个URL）。然而，HTTP完美地工作。

有什么想法发生了什么？

预先感谢。

解决方案

降级到请求== 2.1.0为我工作。

拥有最新的urllib3对于解决一个不相关的bug（ import pwd ，如我记得的）。

希望App Engine很快就能解决这个问题，因为要求不会的。

编辑：

我认为你也可以在最新的要求中修改这个，通过评论 sessions.py中的第161-175行。未经测试。

I'm using python-request on Google App Engine and it's not working as expected for HTTPS. Let's see an example:

import requests
requests.get('https://www.digitalocean.com')

That line works perfectly if I execute it in a terminal. Response is 200 OK (without redirects).

However, if I execute it on GAE a TooManyRedirects error is raised. Trying to figure out what's the problem I execute with allow_redirects=False and I can see that the response is a redirect (301) which points to the same url!!! ('location' header value is 'https://www.digitalocean.com'). This obviously (when allow_redirect=True) happens over and over again until the TooManyRedirects error is raised.

So it seems that python-requests is not working on GAE for HTTPS (I've tested with several URL). However HTTP works perfectly.

Any idea about what's happening?

Thanks in advance.

解决方案

Downgrading to requests==2.1.0 worked for me.

Having an up-to-date urllib3 is important for resolving an unrelated bug (import pwd, as I recall).

Hopefully App Engine fixes this soon, as requests won't.

EDIT:

I think you can also patch this in the latest requests by commenting lines 161-175 in sessions.py. Untested.
