如何使与grequests

Question

HTTP POST请求我试过如下：

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) 

但它说以下内容：

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

我还需要传递给处理回调的响应。

grequests.post（）函数只接受一个位置参数，即您向其发送POST请求的URL。剩下的参数被当作关键字参数。

所以你需要调用grequests.post（）为：

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)
