如何处理 urllib3 中的代理 [英] How to handle proxies in urllib3

问题描述

我无法找到有关如何在 urllib3 中构建简单脚本的可靠示例，该脚本打开一个 url(通过代理)，然后读取它并最终打印它.代理需要用户/通行证才能进行身份验证，但是我不清楚您是如何做到这一点的?任何帮助将不胜感激.

I am having trouble finding solid examples of how to build a simple script in urllib3 which opens a url (via a proxy), then reads it and finally prints it. The proxy requires a user/pass to authenticate however it's not clear to me how you do this? Any help would be appreciated.

推荐答案

urllib3 有一个 <您可以使用的 code>ProxyManager 组件.您需要为 Basic Auth 组件构建标头，您可以手动完成，也可以使用 make_headers urllib3 中的帮助器.

urllib3 has a ProxyManager component which you can use. You'll need to build headers for the Basic Auth component, you can either do that manually or use the make_headers helper in urllib3.

放在一起，它看起来像这样:

All together, it would look something like this:

from urllib3 import ProxyManager, make_headers

default_headers = make_headers(proxy_basic_auth='myusername:mypassword')
http = ProxyManager("https://myproxy.com:8080/", proxy_headers=default_headers)

# Now you can use `http` as you would a normal PoolManager
r = http.request('GET', 'https://stackoverflow.com/')
