curl报60的问题（curl failed to verify the legitimacy of the server）

使用curl发请post请求的时候，会遇到如下错误：

curl: (60) SSL certificate problem: self signed certificate
More details here: curl - SSL CA Certificates

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above. 

 查看官网的解释是说因为证书认证缺失，所以可以考虑请求里面关闭ssl证书认证，命令行中加上-k即可，如

curl -d "a=test1&b=fu&c=tet2" https://****/*****/***/getUserInfo -k
