当我不使用HTTPS或者使用使用别家的HTTPS代理是,都能正常,但是唯独使用这家的HTTPS时发生握手失败问题

proxies = {
    'http':"http://175.172.81.174:5324",
    'https':"http://175.172.81.174:5324",
}
import requests
r = requests.get("https://weibo.com/signup/signup.php",proxies=proxies,verify=False)

HTTPSConnectionPool(host='weibo.com', port=443): Max retries exceeded
with url: /signup/signup.php (Caused by SSLError(SSLError(1, u'[SSL:
UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:661)'),))

当使用下面代码时,每次都能成功:

from OpenSSL import SSL

import socket
proxies = {
    'http':"http://175.172.81.174:5324",
    'https':"http://175.172.81.174:5324",
}
headers = """GET https://weibo.com/signup/signup.php HTTP/1.1

print s.recv(4096)      

ctx = SSL.Context(SSL.TLSv1_METHOD)
ctx.set_verify(SSL.VERIFY_PEER, verify_cb)

有办法让Requests正常使用这个代理IP吗,如果你愿意帮我测试,请提供给我你的IP,因为使用这个代理前需要授权
