Thinkphp5,微信支付宝退款

发布时间:2020-04-20作者:小灵龙来源:未知点击:120

第一步:整理支付宝 参数,appid,密码等。在extra文件夹下建立一个文件ali.php,把参数都放进去。

1,支付宝app支付三大基本参数:  APPID; 秘钥,应用公钥;
2,支付宝退款三大基本参数: APPID; 秘钥,支付宝公钥;
3,支付宝需要自己生成唯一订单号,这个和支付宝商户中心商户订单号不一样,但成功后回调也会把我们这个发过去的订单号回调发过来,以此订单号为条件,查询订单表数据,更改订单状态;可以顺便把支付宝交易号回调过来保存数据库,后面退款需要用到.
4,支付宝回调地址必须公网可以访问

<?php
//支付宝配置文件
return [   
   
    'zhn' => [
        //应用ID APPID)
        'app_id' =>'25555644',
        // ֧异步通知地址
        'notify_url' => 'http://localhost/admin/payment/notify',
        // ֧//同步跳转
        'return_url' => '',
        //支付宝网关
        'gatewayUrl'=>'https://openapi.alipay.com/gateway.do',
        //支付宝公钥
        'ali_public_key' => '9ulOzQH63idl05qQIDAQAB',
        // 开发者私钥
        'private_key' => '
9ulOzQH63idl05qQIDAQAB',
        'log' => [ // optional
            'file' => '../storage/logs/alipay.log',
            'level' => 'info', //
            'type' => 'single', //
            'max_file' => 30, //
        ],
        'http' => [
            'timeout' => 5.0,
            'connect_timeout' => 5.0,
        ],
    ]
]

?>


第二步:去支付宝开放平台下载 App支付服务端 DEMO & SDK
解压后放入vendor文件夹
jinghuajuanke.cn

第三步:建立一个控制器,支付类。

<?php
namespace app\admin\Controller;
use think\Controller;
use think\Loader;
use think\Request;
class Payment extends Base{   

    private $appId = '商户id';
    private $rsaPrivateKey = "商户秘钥";
    private $alipayrsaPublicKey = "商户公钥";
    private $aop;
    private $notify_url = "公网服务器域名/index/alipay/notify";
    private $alipayrsaPublicKey_zhifubao = "支护宝公钥";

     //生成唯一订单号退款用
    public  function build_order_no(){
      return date('Ymd').substr(implode(NULL, array_map('ord', str_split(substr(uniqid(), 7, 13), 1))), 0, 8);
    }
    public function __construct()
    {
        $config=config('alipay.zhiun');
       $this->appId=$config['app_id'];
       $this->rsaPrivateKey=$config['private_key'];
       $this->alipayrsaPublicKey_zhifubao=$config['ali_public_key'];

       $this->notify_url=$config['notify_url'];
        Loader::import('alipay.AopSdk');
    } 

   //支付宝app退款  退款用支付宝公钥
    public function exitPay(Request $request)

    {      
         //引入sdk
        vendor('aop.AopClient');
        vendor('aop.request.AlipayTradeRefundRequest');
         $aop = new \AopClient ();

         $aop->signType = "RSA2";
         $aop->postCharset = 'UTF-8';
         $aop->format = "json";
         $request = new \AlipayTradeRefundRequest (); 

          //需要传入的参数变量
          $trade_no  = ""; //支付宝交易号,和商户订单号不能同时为空
          $refund_fee = "10";//退款金额
          $out_trade_no = "87177359170";//订单支付时传入的商户订单号,不能和 trade_no同时为空。 

          $request->setBizContent("{" .

            "\"trade_no\":\"{$trade_no}\"," . //支付宝交易号,和商户订单号不能同时为空 特殊可选

            "\"out_trade_no\":\"{$out_trade_no}\"," .  //订单支付时传入的商户订单号,不能和 trade_no同时为空。 特殊可选

            "\"refund_reason\":\"退款\"" . //退款的原因说明    正常退款 可选 最后的“,”逗号去掉

            "}"); 

          $result = $aop->execute($request);
          $responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";
          $resultCode = $result->$responseNode->code;
          if(!empty($resultCode) && $resultCode == 10000){
              //退款成功,处理订单状态以及更新退款等信息 
              return json(['code'=>200,'msg'=>'退款成功']);

          } else {

        $request->setNotifyUrl($this->notify_url);

        $request->setBizContent($bizcontent);

       //这里和普通的接口调用不同,使用的是sdkExecute

        $response = $aop->sdkExecute($request);
