Python requests: limiting the number of redirects

Is there a way to limit the number of redirects that will be performed on python requests when doing a GET?

I know about allow_redirects=False

, but that just prevents the redirection all together. I'm looking for a way to keep track of the redirect, up to some maximum number of conversions.

# What I know how to do:
resp = requests.get(url)  # follows redirects "infinitely"
resp = requests.get(url, allow_redirects=False)  # follows no redirects

# What I'm trying to do:
resp = requests.get(url, max_redirects=3)  # follow up to 3 redirects

Thank!

You need to create an object Session

and set the variable max_redirects

to 3

session = requests.Session()
session.max_redirects = 3
session.get(url)


TooManyRedirects

the exception will be raised if requests exceed the maximum number of redirects.

per request https://github.com/kennethreitz/requests/issues/1300

If you want to get the header (or other information) of the request that caused the Max Rediect Limit Exception, you can do this:

session = requests.Session()
session.max_redirects = 1
try:
    r = session.post(url, headers = headers, params = querystring, data = payload)
except requests.exceptions.TooManyRedirects as exc:
    r = exc.response


Make sure your details are the latest release.
