微信小店调用api代码示例

刚开始调用微信小店api的时候，可能大家会遇到问题。系统总是提示system error，归根结底还是发送的参数不正确。

下面给出几个调用例子：

例子写得不全。

<?php
       function cUrlRequest($url,$data = null){
            $curl = curl_init();
            curl_setopt($curl, CURLOPT_URL, $url);
            curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
            curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);
            if (!empty($data)){
                curl_setopt($curl, CURLOPT_POST, 1);
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            }
            curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
            $output = curl_exec($curl);
            curl_close($curl);
            return $output;
        }
