laravel 框架接入第三方扫码支付（万众云平台）

首先在控制器拿到方法，去请求第三方的扫码支付接口

//去充值的界面
	public function recharge(Request $request){

		$data['money']=$request->input('money');//钱数
		$data['order_id']=$request->input('order_id');//订单号
		$data['card_num']=$request->input('card_num');//元宝数量
		$data['username']=$request->session()->get("username");//用户昵称

		$url = 'http://epay.taidupay.com/api/pay/unifiedOrder';
		$key = '';//平台申请的app_key
		$datas = [
			'appId' =>'',//平台申请的app_id
			'timestamp' => (string)time(),
			'nonce' => time().rand(),
			'service' => 'alipay.native',
			'orderNo' => $data['order_id'],
			'totalAmount' =>1,
			'clientIp' => '116.62.214.81',
			'attach' => 'ces',
			'notifyUrl' => 'http://116.62.214.81/city.php',//异步回调地址(必须是外网访问到的地址)
			'body' => '元宝',
		];
		ksort($datas);

		$signOStr = '';
		foreach ($datas as $k => $val) {
			if ($signOStr != '') {
				$signOStr .= '&';
			}
			$signOStr .= $k . '=' . $val;
		}
		$signOStr = $signOStr . '&key=' . $key;
		$datas['sign'] = strtoupper(MD5($signOStr));

		$data['rs'] = json_decode($this->json_post($url, json_encode($datas)), true);
		//print_r($data['rs']);die;
		if($data['rs']['success'] == true && $data['rs']['status'] == 0){
			
			echo json_decode($data['rs']['payInfo'], true);
		}else{
			echo "<script> alert('订单编号重复！');parent.location.href='http://116.62.214.81/userInfo'; </script>"; 

		}
		
		return view('recharge')->with('data', $data);

	}

public function json_post($url, $data){
		$ch = curl_init();
		$header = [
			'Accept-Charset: utf-8',
			'Content-Type: application/json'
		];
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
		curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
		curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.0)');
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
		curl_setopt($ch, CURLOPT_AUTOREFERER, 1);
		curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		$tmpInfo = curl_exec($ch);
		$errorno=curl_errno($ch);

		return $tmpInfo;
	}

city.php文件内容

<?php
header("Content-type:text/html;charset=utf-8");
	$get_data = file_get_contents('php://input', 'r');
	//file_put_contents('a.txt',$get_data);

		$get_data = json_decode($get_data, true);
		$key = '1bdc6c80b3cb8987e2720bd965748593f07bb3e9';
		$data = $get_data;
		unset($data['sign']);
		ksort($data);


		$signOStr = '';
		foreach ($data as $k => $val) {
			if ($signOStr != '') {
				$signOStr .= '&';
			}
			$signOStr .= $k . '=' . $val;
		}
		$signOStr = $signOStr . '&key=' . $key;
		$sign = strtoupper(MD5($signOStr));

		if($sign == $get_data['sign'] && $data['status'] == 3){
			$dbms='mysql';//数据库类型
			$dbName='youleapp';//使用的数据库
			$users='root';//数据库连接用户名
			$pwd='root';//数据库连接密码
			$host='127.0.0.1';//数据库主机名
			$dsn="$dbms:host=$host;port=3306;dbname=$dbName";
			$pdo=new PDO($dsn,$users,$pwd);//初始化一个PDO对象，就是创建了数据库连接对象$pdo
		   //成功
			$out_trade_no=$data['orderNo'];//订单号
			$trade_no=$data['platformOrderNo'];
			$pay_time=$data['finishTime'];
			//通过订单号修改订单id

			$updatesql="UPDATE pay_order set trade_no='$trade_no',pay_time='$pay_time',status=1 WHERE order_id='$out_trade_no'";
			$res=$pdo->exec($updatesql);
				if($res==1){
					//修改完状态之后要给用户加上元宝
					//$order_user=$model_payorder->getorder($out_trade_no);
					//查询修改完订单的信息
					$query1="select * from `pay_order` where order_id='$out_trade_no'";//需要执行的sql语句
					$res1=$pdo->prepare($query1);//准备查询语句
					$res1->execute();//
					$arr=$res1->fetch(PDO::FETCH_ASSOC);

					
					$uid=$arr['uid'];//用户的id
					$querys="select * from `user` where id='$uid'";//需要执行的sql语句
					$res2=$pdo->prepare($querys);//准备查询语句
					$res2->execute();//
					$user=$res2->fetch(PDO::FETCH_ASSOC);

					$acer_money=$user['acer_money'];
					$card_num=$arr['card_num'];
					$updatesq="UPDATE `user` set acer_money='$acer_money'+'$card_num' WHERE id='$uid'";
					$result=$pdo->exec($updatesq);
					if($result==1){
						
						echo "success";
					}
				}else{
					echo "fail";
				}

		}else{

		  echo "fail";
		}
		
		
		

这就完成了。还有一个问题就是  扫码之后，页面跳转问题，别着急，小姐姐会一一给你解答。

注意放到充值的页面

$(document).ready(function () {
	    setInterval("ajaxstatus()", 17000);    
	});
	
	function ajaxstatus() {
		var order_id=$("#out_trade_no").val();
		//alert(order_id);
	    if ($("#out_trade_no").val() != 0) {

			$.ajax({
			url: "pay/order",
			type: "GET",
			dataType:'jsonp',
			async: false,
			data: {order_id:order_id},
			success: function(msg) {
				if(msg.status == 1) {
					//注册成功调到登录页面
				
					window.location.href = "/userInfo";
				} else {
					layer.msg('请求订单状态出错!', {icon: 7, time: 2000});
					return false;	                
				}

			}
			});
	    }
	
	}

ajax请求的地址pay/order控制器操作

//跳转页面
	 public  function paysorder(Request $request){
		 $order_id=$request->input('order_id','');
		 $callback=$_GET['callback'];
		 $model_payorder=new PayOrder();
		 $info=$model_payorder->getorder($order_id);
		 if($info){
			 $response = array(
				'state'  => 200,
				'message' => '成功',
				'order_id' => $info['order_id'],
				'status' => $info['status'],
				
			);
			exit( $callback.'('.json_encode($response).')');
		 }else{
			 $response = array(
				'state'  => 202,

			);
			exit( $callback.'('.json_encode($response).')');
		 }
		 
		 
	 }
