Understand the Alipay web payment function implemented in php [based on TP5 framework]

The example in this article describes the Alipay web payment function implemented in PHP. Share it with everyone for your reference, the details are as follows:

1. Submit payment request

require_once './payment/zfb/pagepay/service/AlipayTradeService.php';
require_once './payment/zfb/pagepay/buildermodel/AlipayTradePagePayContentBuilder.php';
$payInfo=Db::name('pay_type')->where(['pay_id'=>1])->find();
$zfb=json_decode($payInfo['pay_json'],true);
$config=[
  'app_id'=>$zfb['app_id'],
  'merchant_private_key'=>$zfb['merchant_private_key'],
  'notify_url'=>config('z_notify_url'),
  'return_url'=>config('z_return_url'),
  'charset'=>config('charset'),
  'sign_type'=>config('sign_type'),
  'gatewayUrl'=>config('gatewayUrl'),
  'alipay_public_key'=>$zfb['alipay_public_key']
];
//商品订单号
$out_trade_no=$orderData['order_number'];
//订单名称,必填
$subject='充值订单';
//付款金额
$total_amount=$money;
//商品描述
$body = $out_trade_no . '-' . $this->agent_id.'-'.$money;
$payRequestBuilder = new \AlipayTradePagePayContentBuilder();
$payRequestBuilder->setBody($body);
$payRequestBuilder->setSubject($subject);
$payRequestBuilder->setTotalAmount($total_amount);
$payRequestBuilder->setOutTradeNo($out_trade_no);
$aop = new \AlipayTradeService($config);
$response = $aop->pagePay($payRequestBuilder,$config['return_url'],$config['notify_url']);
echo $response;
Copy after login

2. Asynchronous callback Alipay parameter authentication

$pay=Db::name('pay_type')->where(['pay_id'=>1])->find();
  $zfb=json_decode($pay['pay_json'],true);
  $config = [
    'app_id' => $zfb['app_id'],
    'merchant_private_key' => $zfb['merchant_private_key'],
    'notify_url' => config('z_notify_url'),
    'return_url' => config('z_return_url'),
    'charset' => config('charset'),
    'sign_type' => config('sign_type'),
    'gatewayUrl' => config('gatewayUrl'),
    'alipay_public_key' => $zfb['alipay_public_key']
  ];
  $arr=$_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。
  */
  if($result) {//验证成功
    ////////////////////////////////////////////////////////////////////////////////
    //请在这里加上商户的业务逻辑程序代
    //——请根据您的业务逻辑来编写程序(以下代码仅作参考)——
    //获取支付宝的通知返回参数,可参考技术文档中服务器异步通知参数列表
    //商户订单号
    $out_trade_no = $_POST['out_trade_no'];
    //支付宝交易号
    $trade_no = $_POST['trade_no'];
    //交易状态
    $trade_status = $_POST['trade_status'];
    //交易金额
    $total_amount = $_POST['total_amount'];
    if($_POST['trade_status'] == 'TRADE_FINISHED') {
      //判断该笔订单是否在商户网站中已经做过处理
      //如果没有做过处理,根据订单号(out_trade_no)在商户网站的订单系统中查到该笔订单的详细,
      并执行商户的业务程序
      //请务必判断请求时的total_amount与通知时获取的total_fee为一致的
      //如果有做过处理,不执行商户的业务程序
      //注意:
      //退款日期超过可退款期限后(如三个月可退款),支付宝系统发送该交易状态通知
    } else if ($_POST['trade_status'] == 'TRADE_SUCCESS') {
      //判断该笔订单是否在商户网站中已经做过处理
      //如果没有做过处理,根据订单号(out_trade_no)在商户网站的订单系统中查到该笔订单的详细,
      并执行商户的业务程序
      //请务必判断请求时的total_amount与通知时获取的total_fee为一致的
      //如果有做过处理,不执行商户的业务程序
      //注意:
      //付款完成后,支付宝系统发送该交易状态通知
      //此处应该更新一下订单状态,商户自行增删操作
       这里写你的逻辑程序
    }
    //——请根据您的业务逻辑来编写程序(以上代码仅作参考)——
    echo 'success';
  }else {
    //验证失败
    echo "fail";
  }
}
Copy after login

3. Synchronous callback page jump processing Synchronization only does a jump processing and does not write any data processing

$pay=Db::name('pay_type')->where(['pay_id'=>1])->find();
$zfb=json_decode($pay['pay_json'],true);
$config = [
  'app_id' => $zfb['app_id'],
  'merchant_private_key' => $zfb['merchant_private_key'],
  'notify_url' => config('z_notify_url'),
  'return_url' => config('z_return_url'),
  'charset' => config('charset'),
  'sign_type' => config('sign_type'),
  'gatewayUrl' => config('gatewayUrl'),
  'alipay_public_key' => $zfb['alipay_public_key']
];
$arr=$_GET;
$alipaySevice = new \AlipayTradeService($config);
$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。
*/
if($result) {//验证成功
  ///////////////////////////////////////////////////////////////////////////////
  //请在这里加上商户的业务逻辑程序代码
  //——请根据您的业务逻辑来编写程序(以下代码仅作参考)——
  //获取支付宝的通知返回参数,可参考技术文档中页面跳转同步通知参数列表
  //商户订单号
  $out_trade_no = htmlspecialchars($_GET['out_trade_no']);
  //支付宝交易号
  $trade_no = htmlspecialchars($_GET['trade_no']);
  $this->success("支付成功",url('Index/index'));
  //——请根据您的业务逻辑来编写程序(以上代码仅作参考)——
  ///////////////////////////////////////////////////////////////////////////
}
else {
  //验证失败
  echo "验证失败";
}
Copy after login
