对于任何一款软件来说，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宝、微信和银联卡，而大多数开发技术人员对于如何调用支付宝的支付接口还存在很大的困扰，今天app开发报价燚轩科技就来跟大家分享一下如何正确调用支付宝支付接口的实现，代码如下所示：

   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){

            //商户订单号，商户网站订单系统中唯一订单号，必填

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

            //订单名称，必填

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

            //付款金额，必填

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

            $total_amount = 0.01;

            //商品描述，可空

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

            //构造参数

            $payRequestBuilder = new AlipayTradePagePayContentBuilder();

            $payRequestBuilder->setBody($body);

            $payRequestBuilder->setSubject($subject);

            $payRequestBuilder->setTotalAmount($total_amount);

            $payRequestBuilder->setOutTradeNo($out_trade_no);

            $aop = new AlipayTradeService($config);

          /**

           * pagePay 电脑网站支付请求

           * @param $builder 业务参数，使用buildmodel中的对象生成。

           * @param $return_url 同步跳转地址，公网可以访问

           * @param $notify_url 异步通知地址，公网可以访问

           * @return $response 支付宝返回的信息

          */

          $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);

          //输出表单

          var_dump($response);          

        }

}

    public function updatezfb(){

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

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

        $arr=$_POST;

        $alipaySevice = new AlipayTradeService($config);

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

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

        /* 实际验证过程建议商户添加以下校验。

        1、商户需要验证该通知数据中的out_trade_no是否为商户系统中创建的订单号，

        2、判断total_amount是否确实为该订单的实际金额（即商户订单创建时的金额），

        3、校验通知中的seller_id（或者seller_email) 是否为out_trade_no这笔单据的对应的操作方（有的时候，一个商户可能有多个seller_id/seller_email）

        4、验证app_id是否为该商户本身。
