我编写了可用于代理身份验证的类（基于摘要身份验证）。 我从request.auth.HTTPDigestAuth借用了几乎所有代码。
import requests
import requests.auth
class HTTPProxyDigestAuth(requests.auth.HTTPDigestAuth):
def handle_407(self, r):
"""Takes the given response and tries digest-auth, if needed."""
num_407_calls = r.request.hooks['response'].count(self.handle_407)
s_auth = r.headers.get('Proxy-authenticate', '')
if 'digest' in s_auth.lower() and num_407_calls < 2:
self.chal = requests.auth.parse_dict_header(s_auth.replace('Digest ', ''))
# Consume content and release the original connection
# to allow our new request to reuse the same one.
r.content
r.raw.release_conn()
r.request.headers['Authorization'] = self.build_digest_header(r.request.method, r.request.url)
r.request.send(anyway=True)
_r = r.request.response
_r.history.append(r)
return _r
return r
def __call__(self, r):
if self.last_nonce:
r.headers['Proxy-Authorization'] = self.build_digest_header(r.method, r.url)
r.register_hook('response', self.handle_407)
return r
用法：
proxies = {
"http" :"192.168.20.130:8080",
"https":"192.168.20.130:8080",
}
auth = HTTPProxyDigestAuth("username", "password")
# HTTP
r = requests.get("http://www.google.co.jp/", proxies=proxies, auth=auth)
r.status_code # 200 OK
# HTTPS
r = requests.get("https://www.google.co.jp/", proxies=proxies, auth=auth)
r.status_code # 200 OK
