如何使用grequests发出HTTP POST请求

Question

I tried the following:

import grequests

urls = ['http://localhost/test', 'http://localhost/test']

params = {'a':'b', 'c':'d'}
rs = (grequests.post(u, params) for u in urls)
grequests.map(rs)

But it says the following:

File "search.py", line 6, in <genexpr>
rs = (grequests.post(u, params) for u in urls)
TypeError: __init__() takes exactly 3 arguments (4 given)

I also need to pass the response to a callback for processing.

grequests.post() function takes only one positional argument ie URL to which you have send that POST request. The rest of the parameters are taken as key word arguments.

So you need to call grequests.post() as:

import grequests

urls = ['http://localhost/test', 'http://localhost/test']

params = {'a':'b', 'c':'d'}
rs = (grequests.post(u, data=params) for u in urls)
grequests.map(rs)
