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;
        }

        //获取所有商品
        function gStateProduct($state = 0,$token){
             //https://api.weixin.qq.com/merchant/getbystatus?access_token=ACCESS_TOKEN 
             //{"status": 0}

             print_r( json_decode($ResData) );
        }

                $access_token = $jsoninfo["access_token"];
                return $access_token;
        }

        //根据product_id来获取单个商品
        function getOneProductByid($state = 0,$token)
        {
            $url="https://api.weixin.qq.com/merchant/get?access_token=".$token;

        }
        
                $AccessToken=getAccessToken();

        getOneProductByid("pf82VwN45zr8eOlur5mAiSTjg8WU",$AccessToken);
