grequests.post（）正在返回无

Question

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

我做错了什么？

Answer 1

你需要传递一个会话实例，而不是一个会话类：

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