我可以毫无问题地执行以下操作：
curl -u "username:password" http://www.example.com/exportfile.xml
但是如果我尝试对我们网站的 https 版本使用相同的命令，它就会失败
curl -u "username:password" https://www.example.com/exportfile.xml
这是错误消息的样子：
About to connect() to www.example.com port 443 (#0)
Trying "some ip"... connected
Connected to www.example.com (some ip) port 443 (#0)
