curl报错60的问题

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: https://curl.haxx.se/docs/sslcerts.html

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://testtest.com/test/test2/getUserInfo -k

如果是在php代码中，则需要加入下面的代码：

if(substr($url,0,5) == 'https'){
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, true);
}
