postman 简单的实现接口登陆添加(php 生成token值验证)

对应的父级控制器 AppController.php :  Curl方法

             curl_setopt($ch,CURLOPT_URL,$url);
             curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);

             curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);


             if ($month=='post') {
                 curl_setopt($ch, CURLOPT_POST, 1);
                 curl_setopt($ch, CURLOPT_POSTFIELDS, $can);

             }
             $data = curl_exec($ch);


             curl_close($ch);

             return $data;
