【PHP】PHP服務端支付寶支付及回調

支付寶支付

（由app端自行調起支付寶/微信）

1.下載PHP版SDK 

<?php

define('IN_ECS', true);

/*App支付 PHP服務端*/
/*引入支付寶PHP SDK*/
header("Content-type:text/html;charset=utf-8;");
require_once('../alipay-sdk-PHP/aop/request/AlipayTradeAppPayRequest.php');
require_once('../alipay-sdk-PHP/aop/AopClient.php');


$user_id  = isset($_REQUEST['user_id']) ? trim($_REQUEST['user_id']) : 0;
$money = isset($_REQUEST['amount']) ? trim($_REQUEST['amount']) : 0;

if($user_id == 0 || $money ==0){
    $result  = array('code' => 1,'data'=>'缺少參數' );
    die(json_encode($result));
}


$aop = new AopClient;
$aop->gatewayUrl = "https://openapi.alipay.com/gateway.do";
$aop->appId = "appid";
$aop->format = "json";
$aop->charset = "utf-8";
$aop->signType = "RSA2";
$aop->rsaPrivateKey = '開發者私鑰';

$aop->alipayrsaPublicKey = '支付寶公鑰';



//實例化具體API對應的request類,類名稱和接口名稱對應,當前調用接口名稱：alipay.trade.app.pay

$request = new AlipayTradeAppPayRequest();
//SDK已經封裝掉了公共參數，這裏只需要傳入業務參數
$trade_no = chongzhi_sn();
//入庫信息
require(dirname(__FILE__) . '../../includes/init.php');
include_once(ROOT_PATH .'includes/lib_clips.php');

$user_m = get_user_info($user_id);

$dbcontent = array(
    'user_id'    => $user_id,
    'amount'  => $money,
    'user_name' => $user_m['user_name'],
    'payment' => "支付寶",
    'cz_sn'  => $trade_no,
    'add_time'  => gmtime()
);
//傳參信息
$bizcontent = array(
    'body' =>(string)$trade_no,
    'subject'  =>'充值',
    'total_amount'  => $money,
    'out_trade_no'  => (string)$trade_no,
    'product_code' => 'QUICK_MSECURITY_PAY',
    'timeout_express'=> '30m'
);

$bizcontent = json_encode($bizcontent);
$request->setNotifyUrl("支付回調地址");
$request->setBizContent($bizcontent);
//這裏和普通的接口調用不同，使用的是sdkExecute
$response = $aop->sdkExecute($request);
//htmlspecialchars是爲了輸出到頁面時防止被瀏覽器將關鍵參數html轉義，實際打印到日誌以及http傳輸不會有這個問題
//echo htmlspecialchars($response);//就是orderString 可以直接給客戶端請求，無需再做處理。

if($response){
    if($GLOBALS['db']->autoExecute($ecs->table('user_chongzhi'), $dbcontent, 'INSERT'))
    {
        $result = array('code'=>0,'data'=>$response);
    }else{
        $result = array('code'=>1,'data'=>'意外出錯，請聯繫客服。');
    }
    die(json_encode($result));
}

function chongzhi_sn()
{
    /* 選擇一個隨機的方案 */
    mt_srand((double) microtime() * 1000000);
    return date('Ymd') . str_pad(mt_rand(1, 99999), 5, '0', STR_PAD_LEFT);
}

?>

 

回調

<?php
define('IN_ECS', true);



require_once('../alipay-sdk-PHP/aop/request/AlipayTradeAppPayRequest.php');
require_once('../alipay-sdk-PHP/aop/AopClient.php');

$aop = new AopClient;
$aop->alipayrsaPublicKey = '支付寶公鑰';
$flag = $aop->rsaCheckV1($_POST, NULL, "RSA2");




$myfile = fopen("testfile.txt", "a");
fwrite($myfile, "\r\n");
fwrite($myfile, json_encode($_POST));

if($_POST['trade_status'] == 'TRADE_SUCCESS' ){
    //業務處理

    echo 'success';
    
}else{
    echo 'fail';
}
fclose($myfile);
?>
