python - requests.exceptions.SSLError : ("bad handshake: Error([(' SSL routines', 'SSL23_GET_SERVER_HELLO' , 'sslv3 alert handshake failure' )],),)

Question

我做到了

import requests

url = "https://randomuser.me/api/"
data = requests.get(url).json()


print data

我不断得到

Traceback (most recent call last):
  File "/Applications/MAMP/htdocs/code/python/curl.py", line 4, in <module>
    data = requests.get(url).json()
  File "/Library/Python/2.7/site-packages/requests/api.py", line 70, in get
    return request('get', url, params=params, **kwargs)
  File "/Library/Python/2.7/site-packages/requests/api.py", line 56, in request
    return session.request(method=method, url=url, **kwargs)
  File "/Library/Python/2.7/site-packages/requests/sessions.py", line 475, in request
    resp = self.send(prep, **send_kwargs)
  File "/Library/Python/2.7/site-packages/requests/sessions.py", line 596, in send
    r = adapter.send(request, **kwargs)
  File "/Library/Python/2.7/site-packages/requests/adapters.py", line 497, in send
    raise SSLError(e, request=request)
requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'SSL23_GET_SERVER_HELLO', 'sslv3 alert handshake failure')],)",)

但是如果我运行这个 curl https://randomuser.me/api/

在我的终端上，我得到了

您的代码非常适合我使用 Python 2.7.12。你没有给出你正在使用的 Python 的确切版本，但我的猜测是它是 2.7.9 之前的版本。在 2.7.9 中完成了对 SSL 实现的几处更改，包括添加对 Server Name Indication (SNI) 的支持。 .您的目标 URL 需要在客户端支持 SNI，这在使用 SSLLabs 测试站点时可以看出。 :

This site works only in browsers with SNI support.

您显示的跟踪对于不支持 SNI 的客户端来说是典型的。来自FAQ for requests :

Python3 and Python 2.7.9+ include native support for SNI in their SSL modules. For information on using SNI with Requests on Python < 2.7.9 refer to this Stack Overflow answer.
