httplib2 还没实现代理功能，凉了？

实际情况是我需要用谷歌的 api,就是 googleapiclient 这个包，那么还得代理下才能用，看了源码需要传一个设置好代理的 http 实例过去，但是死活就不行

测试了下

import httplib2
http = httplib2.Http(proxy_info=httplib2.ProxyInfo( httplib2.socks.PROXY_TYPE_SOCKS5, '127.0.0.1', 1080),timeout=10)
resp, content = http.request('https://www.google.com', 'GET')
print(resp)

根本没走代理，谷歌无果，心灰意冷，翻翻源码，才发现

class HTTPSConnectionWithTimeout( http.client.HTTPSConnection):
    """
    This class allows communication via SSL.

    All timeouts are in seconds. If None is passed for timeout then
    Python's default timeout for sockets will be used. See for example
    the docs of socket.setdefaulttimeout():
    http://docs.python.org/library/socket.html#socket.setdefaulttimeout
    """

    def __init__(self, host, port=None, key_file=None, cert_file=None,
                 timeout=None, proxy_info=None,
                 ca_certs=None, disable_ssl_certificate_validation=False):
        # TODO: implement proxy_info
        self.proxy_info = proxy_info
        context = None

TODO: implement proxy_info,凉了？

py 新手，很久以前学了下然后语法啥都忘光了，刚刚捡起来，各位看看我说的对不对，还有没有办法解决我的实际情况
