请求，绑定到一个 ip [英] Requests, bind to an ip

问题描述

我有一个使用 urllib2 发出一些请求的脚本.

I have a script that makes some requests with urllib2.

我使用堆栈溢出其他地方建议的技巧来绑定另一个IP到应用程序，我的电脑有两个 IP 地址(IP A 和 IP B).

I use the trick suggested elsewhere on Stack Overflow to bind another ip to the application, where my my computer has two ip addresses (IP A and IP B).

我想改用requests 图书馆.有谁知道我如何使用该库实现相同的功能?

I would like to switch to using the requests library. Does anyone knows how I can achieve the same functionality with that library?

推荐答案

查看 requests 模块，看起来它使用 httplib 发送 http 请求.httplib 使用 socket.create_connection() 连接到 www 主机.

Looking into the requests module, it looks like it uses httplib to send the http requests. httplib uses socket.create_connection() to connect to the www host.

知道并遵循您提供的链接中的猴子修补方法:

Knowing that and following the monkey patching method in the link you provided:

import socket

real_create_conn = socket.create_connection

def set_src_addr(*args):
    address, timeout = args[0], args[1]
    source_address = ('IP_ADDR_TO_BIND_TO', 0)
    return real_create_conn(address, timeout, source_address)

socket.create_connection = set_src_addr

import requests
r = requests.get('http://www.google.com')

看起来 httplib 将所有参数(到 create_connection())作为参数(vs 关键字)传递给试图扩展 kwargsset_src_addr 中的 dict 失败.我相信以上就是你想要的，但我没有双宿主机可以测试.

It looks like httplib passes all the arguments (to create_connection()) as args (vs keywords) as trying to extend the kwargs dict inside set_src_addr was failing. I believe the above is what you want, but I don't have a dual homed machine to test on.
