grequests.post() is returning None

Question

>>> payload = {'a': 'b'}
>>> url = 'http://someurl/'
>>> req_ = [grequests.post(url, session=requests.session, data=payload)]
>>> r = grequests.map(req_)
>>> r
[None]

am I doing something wrong?

Answer 1

You need to pass a session instance rather than a session class:

>>> session = requests.session()
>>> req_ = [grequests.post(url, session=session, data=payload)]
