使用urllib在Python 3.5中获得网页的最终重定向。

As in this post, I attempt to get the final redirect of a webpage as:

如本文所述，我试图将网页的最终重定向设置为:

import urllib.request
response = urllib.request.urlopen(url)
response.geturl()

But this doesn't work as I get the "HTTPError: HTTP Error 300: Multiple Choices" error when attempting to use urlopen.

但是，当我尝试使用urlopen时，我得到了“HTTPError: HTTPError 300:多个选择”错误。

See documentation for these methods here.

请参阅这里的这些方法的文档。

EDIT:

编辑:

This problem is different than the Python: urllib2.HTTPError: HTTP Error 300: Multiple Choices question, because they skip the error-causing pages, while I have to obtain the final destination.

这个问题不同于Python: urllib2。HTTPError: HTTP错误300:多个选择问题，因为它们跳过错误导致的页面，而我必须获得最终的目的地。

As suggested by @abccd, I used the requests library. So I will describe the solution.

正如@abccd所建议的，我使用了请求库。我来描述一下解。

import requests

url_base = 'something'  # You need this because the redirect URL is relative.
url = url_base + 'somethingelse'

response = requests.get(url)

# Check if the request returned with the 300 error code.
if response.status_code == 300:
    redirect_url = url_base + response.headers['Location']  # Get new URL.
    response = requests.get(redirect_url)  # Make a new request.
