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 requestsimport requests.authclass 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")# HTTPr = requests.get("http://www.google.co.jp/", proxies=proxies, auth=auth)r.status_pre # 200 OK# HTTPSr = requests.get("https://www.google.co.jp/", proxies=proxies, auth=auth)r.status_pre # 200 OK
