本文实例讲述了php版微信小店调用api的方法。分享给大家供大家参考，具体如下：
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}
// $accesstoken = "xxxxxxxx";
$url = "https://api.weixin.qq.com/merchant/getbystatus?access_token=".$token;
//print_r($this->accesstoken);
$resdata = curlrequest($url,'{"status": '.$state.'}'); //特别注意这里，这个是json格式的。
echo "<pre>";
print_r( json_decode($resdata) );
}
//获得所有分组
function getallcategory($state = 0,$token)
{
$url = "https://api.weixin.qq.com/merchant/group/getall?access_token=".$token;
$resdata = curlrequest($url,'{"status": '.$state.'}');
echo "<pre>";
print_r( json_decode($resdata) );
}
//根据分组id来获得商品信息
function getproductbygroudid($state = 0,$token)
{
$url = "https://api.weixin.qq.com/merchant/group/getbyid?access_token=".$token;
$resdata = curlrequest($url,'{"group_id": '.$state.'}');
echo "<pre>";
print_r( json_decode($resdata) );
}
//获取accesstoken
function getaccesstoken()
{
$appid = "your appid";
$appsecret = "your appsecret";
$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=".$appid."&secret=".$appsecret;
$result = curlrequest($url);
$jsoninfo = json_decode($result, true);
$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;
$resdata = curlrequest($url,'{"product_id": "'.$state.'""}');
echo "<pre>";
print_r( json_decode($resdata) );
}
$accesstoken=getaccesstoken();
//gstateproduct(1,$accesstoken);
//getallcategory(1,$accesstoken);
//getproductbygroudid(207061749,$accesstoken);
getoneproductbyid("pf82vwn45zr8eolur5maistjg8wu",$accesstoken);
以上就是php版微信小店调用api示例代码的内容。
