Python请求库重定向新网址

I’ve been looking through the Python Requests documentation but I cannot see any functionality for what I am trying to achieve.

In my script I am setting allow_redirects=True.

I would like to know if the page has been redirected to something else, what is the new URL.

For example, if the start URL was: www.google.com/redirect

And the final URL is www.google.co.uk/redirected

How do I get that URL?

You are looking for the request history.

The response.history attribute is a list of responses that led to the final URL, which can be found in response.url.

response = requests.get(someurl)
if response.history:
    print("Request was redirected")
    for resp in response.history:
        print(resp.status_code, resp.url)
    print("Final destination:")
    print(response.status_code, response.url)
else:
    print("Request was not redirected")

Demo:

>>> import requests
>>> response = requests.get('http://httpbin.org/redirect/3')
>>> response.history
(<Response [302]>, <Response [302]>, <Response [302]>)
>>> for resp in response.history:
...     print(resp.status_code, resp.url)
... 
302 http://httpbin.org/redirect/3
302 http://httpbin.org/redirect/2
302 http://httpbin.org/redirect/1
>>> print(response.status_code, response.url)
200 http://httpbin.org/get

This is answering a slightly different question, but since I got stuck on this myself, I hope it might be useful for someone else.

If you want to use allow_redirects=False and get directly to the first redirect object, rather than following a chain of them, and you just want to get the redirect location directly out of the 302 response object, then r.url won’t work. Instead, it’s the “Location” header:

r = requests.get('http://github.com/', allow_redirects=False)
r.status_code  # 302
r.url  # http://github.com, not https.
r.headers['Location']  # https://github.com/ -- the redirect destination

the documentation has this blurb https://requests.readthedocs.io/en/master/user/quickstart/#redirection-and-history

import requests

r = requests.get('http://www.github.com')
r.url
#returns https://www.github.com instead of the http page you asked for 

I think requests.head instead of requests.get will be more safe to call when handling url redirect,check the github issue here:

r = requests.head(url, allow_redirects=True)
print(r.url)

For python3.5, you can use the following code:

import urllib.request
res = urllib.request.urlopen(starturl)
finalurl = res.geturl()
print(finalurl)
