如何在请求中指定等效于 `--proxy-headers` curl 参数? [英] How does one specify the equivalent of `--proxy-headers` curl argument into requests?

问题描述

我希望在使用请求时只将一些标头传递到我的代理中，但我没有看到这样做的方法.

I'm looking to pass some headers only into my proxies as I'm using requests, and I don't see a method to do it.

urllib3.ProxyManager 有一个 proxy_headers 参数，所以我假设有一种方法可以为请求库设置它 - 我错过了什么吗?

the urllib3.ProxyManager has a proxy_headers parameter, so I would assume there's a way to set it for the requests library - am I missing something?

推荐答案

您可以使用自定义的 HTTPAdapter 来实现(例如如下所示):

You can do it with a customized HTTPAdapter (for example like the following):

import requests

proxyheaders = { 'http://proxy.that.needs.header:8080/': { 'ProxyHeader1': 'SomeValue', 'ProxyHeaderN': 'OtherValue' } }

class ProxyHeaderAwareHTTPAdapter(requests.adapters.HTTPAdapter):
    def proxy_headers(self, proxy):
        if proxy in proxyheaders:
            return proxyheaders[proxy]
        else:
            return None

s = requests.Session()
s.mount('http://', ProxyHeaderAwareHTTPAdapter())
s.mount('https://', ProxyHeaderAwareHTTPAdapter())
s.get(....)
...

如果你喜欢的话，你也可以直接创建并返回一个配置好的 urllib3.ProxyManager 如果你覆盖了 proxy_manager_for 方法而不是 proxy_headers.

You could also directly create and return a configured urllib3.ProxyManager if You overwrite the proxy_manager_for methos instead of proxy_headers if You like.
