使用urllib3忽略证书验证

Question

我将urllib3用于具有自签名证书的私有服务。有什么办法可以让urllib3忽略证书错误并仍然发出请求？

import urllib3
c = urllib3.HTTPSConnectionPool('10.0.3.168', port=9001)
c.request('GET', '/')

使用以下内容时：

import urllib3
c = urllib3.HTTPSConnectionPool('10.0.3.168', port=9001, cert_reqs='CERT_NONE')
c.request('GET', '/')

引发以下错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/urllib3/request.py", line 67, in request
    **urlopen_kw)
  File "/usr/lib/python3/dist-packages/urllib3/request.py", line 80, in request_encode_url
    return self.urlopen(method, url, **urlopen_kw)
  File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 415, in urlopen
    body=body, headers=headers)
  File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 267, in _make_request
    conn.request(method, url, **httplib_request_kw)

    self._send_request(method, url, body, headers)
  File "/usr/lib/python3.3/http/client.py", line 1099, in _send_request
    self.endheaders(body)
  File "/usr/lib/python3.3/http/client.py", line 1057, in endheaders
    self._send_output(message_body)
  File "/usr/lib/python3.3/http/client.py", line 902, in _send_output
    self.send(msg)
  File "/usr/lib/python3.3/http/client.py", line 840, in send
    self.connect()
  File "/usr/lib/python3/dist-packages/urllib3/connectionpool.py", line 103, in connect
    match_hostname(self.sock.getpeercert(), self.host)
  File "/usr/lib/python3/dist-packages/urllib3/packages/ssl_match_hostname/__init__.py", line 32, in match_hostname
    raise ValueError("empty or no certificate")
ValueError: empty or no certificate

使用cURL我能够从服务中获得预期的响应

$ curl -k https://10.0.3.168:9001/
Please read the documentation for API endpoints

尝试以下代码：

import urllib3
c = urllib3.HTTPSConnectionPool('10.0.3.168', port=9001, cert_reqs='CERT_NONE',
                                assert_hostname=False)
c.request('GET', '/')
