一个搭建在SAE上的Django应用，使用新浪微博提供的Python SDK已经稳定运行一年有余，但最近开始持续出现微博认证失败的状况。
摘录微博Python SDK的错误提示如下所示：
ERROR:django.request:Internal Server Error: /weibo/auth/ Traceback (most recent call last): File "/usr/local/sae/python/3rd/django-1.5/django/core/handlers/base.py", line 115, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/data1/www/htdocs/838/app/1/mysite/views.py", line 42, in auth res = weibo_util.keep_user(code,api,redirect_uri) File "/data1/www/htdocs/838/app/1/util/weibo_util.py", line 86, in keep_user r = client.request_access_token(code,redirect_url) File "/data1/www/htdocs/838/app/1/weibo.py", line 255, in request_access_token code = code, grant_type = ‘authorization_code‘) File "/data1/www/htdocs/838/app/1/weibo.py", line 114, in _http_post return _http_call(url, _HTTP_POST, authorization, **kw) File "/data1/www/htdocs/838/app/1/weibo.py", line 155, in _http_call resp = urllib2.urlopen(req) File "/usr/local/sae/python/lib/python2.7/urllib2.py", line 154, in urlopen return opener.open(url, data, timeout) File "/usr/local/sae/python/lib/python2.7/urllib2.py", line 431, in open response = self._open(req, data) File "/usr/local/sae/python/lib/python2.7/urllib2.py", line 449, in _open ‘_open‘, req) File "/usr/local/sae/python/lib/python2.7/urllib2.py", line 409, in _call_chain result = func(*args) File "/usr/local/sae/python/lib/python2.7/urllib2.py", line 1240, in https_open context=self._context) File "/usr/local/sae/python/lib/python2.7/urllib2.py", line 1197, in do_open raise URLError(err) URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:606)> yq66
问题的原因是“SSL: CERTIFICATE_VERIFY_FAILED”。
Google到了这样一篇博文，对解决问题提供了很大的帮助，原文链接：http://reality0ne.com/2014/12/816/
Python 升级到 2.7.9 之后引入了一个新特性，当使用urllib.urlopen打开一个 https 链接时，会验证一次 SSL 证书。
而当目标网站使用的是自签名的证书时就会抛出一个 urllib2.URLError: <urlopen error [SSL:
CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>
的错误消息，详细信息可以在这里查看（https://www.python.org/dev/peps/pep-0476/）。 Additionally ssl._create_stdlib_context is renamed ssl._create_unverified_context (an alias is kept around for backwards compatibility reasons).
解决方案包括下列两种方式：
1. 使用ssl创建未经验证的上下文，在urlopen中传入上下文参数
import ssl import urllib2 context = ssl._create_unverified_context() print urllib2.urlopen("https://www.12306.cn/mormhweb/", context=context).read()
2. 全局取消证书验证
import ssl import urllib2 ssl._create_default_https_context = ssl._create_unverified_context print urllib2.urlopen("https://www.12306.cn/mormhweb/").read()
在此使用方法2，修改weibo.py，在第155行添加下列代码：
import ssl ssl._create_default_https_context = ssl._create_unverified_context
Python [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed 解决方法
