Python 中目前是否有支持 HTTPS 代理进行网络抓取的东西？我目前在 Windows 上使用 Python 2.7，但如果 Python 3 支持 HTTPS 代理协议，我可以使用它。

我尝试使用 mechanize 和 requests 但都在 HTTPS 代理协议上失败。

这个位正在使用mechanize：import mechanize

br = mechanize.Browser()
br.set_debug_http(True)
br.set_handle_robots(False)

br.set_proxies({
    "http"  : "ncproxy1.uk.net.intra:8080",
    "https" : "ncproxy1.uk.net.intra:8080",})
br.add_proxy_password("uname", "pass")

br.open("http://www.google.co.jp/")  # OK
br.open("https://www.google.co.jp/") # Proxy Authentication Required

或使用requests：

import requests
from requests.auth import HTTPProxyAuth

proxyDict = { 
          'http'  : 'ncproxy1.uk.net.intra:8080', 
          'https' : 'ncproxy1.uk.net.intra:8080'
        }
auth = HTTPProxyAuth('uname', 'pass')

r = requests.get("https://www.google.com", proxies=proxyDict, auth=auth)
print r.text

我收到以下消息：

Traceback (most recent call last):
  File "D:\SRC\NuffieldLogger\NuffieldLogger\nuffieldrequests.py", line 10, in <module>
    r = requests.get("https://www.google.com", proxies=proxyDict, auth=auth)

    return request('get', url, **kwargs)

    r = adapter.send(request, **kwargs)

对于请求模块，您可以使用它

#!/usr/bin/env python3

import requests
proxy_dict = {
    'http': 'http://user:passwd@proxy_ip:port',
    'https': 'https://user:passwd@proxy_ip:port'
}
r = requests.get('https://google.com', proxies=proxy_dict)
print(r.text)

我已经对此进行了测试。
