ssl - 为什么在向 sandbox.example.com 等任何子域发送请求时会出现此 SSL 错误？

Question

>>> import requests
>>> requests.get("https://api.example.com/index.php")
<Response [200]>

>>> requests.get("https://sandbox.example.com/index.php")
Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/requests/api.py", line 55, in get
    return request('get', url, **kwargs)
  File "/usr/lib/python2.7/dist-packages/requests/api.py", line 44, in request
    return session.request(method=method, url=url, **kwargs)
  File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 383, in request
    resp = self.send(prep, **send_kwargs)
  File "/usr/lib/python2.7/dist-packages/requests/sessions.py", line 486, in send
    r = adapter.send(request, **kwargs)
  File "/usr/lib/python2.7/dist-packages/requests/adapters.py", line 385, in send
    raise SSLError(e)
SSLError: hostname 'sandbox.example.com' doesn't match either of 'example.com', 'account.example.com', 'api.example.com', 'secure.example s.com'

为什么在 https://sandbox.example.com/index.php 和 https://api.example.com/index.php 都出现此错误 在浏览器上工作正常吗？

Python3 的 SSL 模块包含对 SNI 的原生支持.此支持尚未移植到 Python2。远程服务器可能依赖于 SNI 来为您提供正确的证书，因此会出现错误。

有关在 Python2 上将 SNI 与请求一起使用的信息，请参阅此 Stack Overflow answer .
