對于任何一款軟件來說，支付功能都是核心的，那么目前的主流支付接口主要是支付寶、微信和銀聯卡，而大多數開發技術人員對于如何調用支付寶的支付接口還存在很大的困擾，今天app開發報價燚軒科技就來跟大家分享一下如何正確調用支付寶支付接口的實現，代碼如下所示：

   public function zfbpay1(){

        require_once './ThinkPHP/Extend/Vendor/alipay1/config.php';

        require_once './ThinkPHP/Extend/Vendor/alipay1/pagepay/service/AlipayTradeService.php';

        require_once './ThinkPHP/Extend/Vendor/alipay1/pagepay/buildermodel/AlipayTradePagePayContentBuilder.php';

        $model=M('zfbpay');

        $add['oid']=I('nid');

        $add['type']=1;

        $add['WIDout_trade_no']=trim($_POST['WIDout_trade_no']);

        $add['WIDtotal_amount']=trim($_POST['WIDtotal_amount']);

        $add['WIDsubject']=trim($_POST['WIDsubject']);

        // dump($_POST);die;

        $re=$model->add($add);

        if($re){

            //商戶訂單號，商戶網站訂單系統中唯一訂單號，必填

            $out_trade_no = trim($_POST['WIDout_trade_no']);

            //訂單名稱，必填

            $subject = trim($_POST['WIDsubject']);

            //付款金額，必填

            // $total_amount = trim($_POST['WIDtotal_amount']);

            $total_amount = 0.01;

            //商品描述，可空

            $body = trim($_POST['WIDbody']);

            //構造參數

            $payRequestBuilder = new AlipayTradePagePayContentBuilder();

            $payRequestBuilder->setBody($body);

            $payRequestBuilder->setSubject($subject);

            $payRequestBuilder->setTotalAmount($total_amount);

            $payRequestBuilder->setOutTradeNo($out_trade_no);

            $aop = new AlipayTradeService($config);

          /**

           * pagePay 電腦網站支付請求

           * @param $builder 業務參數，使用buildmodel中的對象生成。

           * @param $return_url 同步跳轉地址，公網可以訪問

           * @param $notify_url 異步通知地址，公網可以訪問

           * @return $response 支付寶返回的信息

          */

          $response = $aop->pagePay($payRequestBuilder,$config['return_url'],$config['notify_url']);

          $map['nid']=I('nid');

          $map['out_trade_no']=$out_trade_no;

            M('need')->save($map);

          //輸出表單

          var_dump($response);          

        }

}

        $arr=$_POST;

        $alipaySevice = new AlipayTradeService($config);

        $alipaySevice->writeLog(var_export($_POST,true));

        $result = $alipaySevice->check($arr);

        /* 實際驗證過程建議商戶添加以下校驗。

        1、商戶需要驗證該通知數據中的out_trade_no是否為商戶系統中創建的訂單號，

        2、判斷total_amount是否確實為該訂單的實際金額（即商戶訂單創建時的金額），

        3、校驗通知中的seller_id（或者seller_email) 是否為out_trade_no這筆單據的對應的操作方（有的時候，一個商戶可能有多個seller_id/seller_email）

        4、驗證app_id是否為該商戶本身。
