python - 如何使用 grequests 发出 HTTP POST 请求

Question

我尝试了以下方法：

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)

我还需要将响应传递给回调进行处理。

Answer 1

grequests.post() 函数只接受一个位置参数，即您向其发送 POST 请求的 URL。其余参数被视为关键字参数。

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)
