[PHP知识库]laravel5.8 支付宝支付

引入官方sdk，composer.json加入

    "autoload": {
   

        "classmap": [
           
            "app/libs/alipay"  //我放到app/libs/alipay
        ]

    },

composer dump-autoload     //当在包中加入新的类，需要更新autoloader  

设置引入命名空间

对AopClient与AlipayTradePagePayRequest分别加入

namespace App\libs\alipay\aop;
namespace App\libs\alipay\aop\request;

新建控制器（AlipayController）

引入AopClient与AlipayTradePagePayRequest文件

use App\libs\alipay\aop\AopClient;
use App\libs\alipay\aop\request\AlipayTradePagePayRequest;

<?php

namespace App\Api\Controllers;


use App\Api\Models\Order;
use App\Http\Controllers\Controller;

use Illuminate\Http\Request;
//use Illuminate\Support\Facades\Log;
use Illuminate\Support\Facades\DB;
use App\libs\alipay\aop\AopClient;
use App\libs\alipay\aop\request\AlipayTradePagePayRequest;

class AliPayController extends Controller {

    public function pay(Request $request){
        $aop = new AopClient();
        $aop->gatewayUrl = '';//支付宝网关
        $aop->appId = ''; // 支付宝appid
        $aop->rsaPrivateKey = ''; // 私钥
        $aop->alipayrsaPublicKey= ''; //支付宝公钥
        $aop->apiVersion = '1.0';
        $aop->signType = 'RSA2';
        $aop->postCharset='UTF-8';
        $aop->format='json';
        //订单信息
        $object = new \stdClass();
        $object->out_trade_no = time();
        $object->total_amount = 100;  //价格
        $object->subject = '书币充值';
        $object->product_code ='FAST_INSTANT_TRADE_PAY';
       // $object->time_expire = date('Y-m-d H:i:s',time());
   
   
        $json = json_encode($object);
        
        //设置同步异步掉地址
        $request = new AlipayTradePagePayRequest();
        $request->setReturnUrl('');  //同步
        $request->setNotifyUrl(''); //异步
        $request->setBizContent($json);
       // dd($request);

        $result = $aop->pageExecute( $request);
        //return $result;
        return json_encode($result);

    }





}

处理异步请求

    public function notify(){
        $aop = new AopClient();

        $aop->alipayrsaPublicKey = ''; //支付宝公钥

        $flag = $aop->rsaCheckV1($_POST, NULL, "RSA2");

        if($flag){
            //处理业务，并从$_POST中提取需要的参数内容
            if($_POST['trade_status'] == 'TRADE_SUCCESS' || $_POST['trade_status'] == 'TRADE_FINISHED'){//处理交易完成或者支付成功的通知
//                file_put_contents('/www/wwwroot/yidu/test.txt',"123",FILE_APPEND);
//                file_put_contents('/www/wwwroot/yidu/test.txt',"<br />",FILE_APPEND);

                //获取订单号
                $orderId = $_POST['out_trade_no'];
                //交易号
                $trade_no = $_POST['trade_no'];

                //此处编写回调处理逻辑
      
                //处理成功一定要返回 success 这7个字符组成的字符串，

                die('success');//响应success表示业务处理成功，告知支付宝无需在异步通知

            }
        }
    }
