python-2.7 - 为什么我从 google adwords api 收到 CERTIFICATE_VERIFY_FAILED？

Question

为什么 google adwords api 停止调用此链接:

https://adwords.google.com/api/adwords/mcm/v201502/CustomerService?wsdl

出现此错误 - 我应该先加载一些证书以及如何加载吗？

urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:590)>

使用 Python 2.7.10。

完整源代码:
create_adwords_client_without_yaml.py

Python 使用来自“系统 ssl 证书存储”的证书来认证 https 连接，如果存储中没有任何合适的 ssl 证书，则会发生这样的错误。
下载 ssl 证书(在浏览器中打开您的 https 链接，然后单击地址栏中的锁定图标 > 更多信息 > 查看证书 > 详细信息 > 导出)并按照此链接的说明将其安装在您的系统上 http://windows.microsoft.com/en-us/windows/import-export-certificates-private-keys#1TC=windows-7
