如何在 laravel 中编写 paypal ipn 侦听器
How to code paypal ipn listener in laravel
我在我的项目中使用了 laravel。在我的项目中使用 paypal 作为支付模块。贝宝支付交易成功完成。但是我想在 laravel 中集成 ipn 侦听器。我不知道如何在 laravel 控制器中集成 ipn 侦听器。

按照以下几步操作:
1)安装Laravel应用程序
2)数据库配置
3)安装所需的包
4)配置paypal.php文件
5)创建路线
6)创建控制器
7)创建视图文件
步骤 1:安装 Laravel 应用程序
我们从头开始,所以我们需要使用波纹管命令来获得新的 Laravel 应用程序,所以打开你的终端或命令提示符和 运行 波纹管命令:
composer create-project --prefer-dist laravel/laravel blog
步骤 2:数据库配置
在此步骤中,我们需要进行数据库配置,您必须在 .env 文件中添加
以下详细信息。
1.Database用户名
1.Database密码
1.Database姓名
在 .env 文件中还有可用的主机和端口详细信息,您可以在系统中配置所有详细信息,因此您可以像下面这样:
.env
DB_HOST=localhost
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret
步骤 3:安装所需的包
我们需要以下 2 个包来在我们的 laravel 应用程序中集成贝宝支付。
在您的 composer.json 文件中添加以下两个包。
"guzzlehttp/guzzle": "~5.4",
"paypal/rest-api-sdk-php": "*",
然后 运行 在您的终端中执行以下命令
php artisan vendor:publish
在 运行 这个命令之后,然后在你的 config/paypal.php 路径中自动创建 paypal.php 文件。
第 4 步:配置 paypal.php 文件
<?php
return array(
/** set your paypal credential **/
'client_id' =>'paypal client_id',
'secret' => 'paypal secret ID',
/**
* SDK configuration
*/
'settings' => array(
/**
* Available options 'sandbox' or 'live'
*/
'mode' => 'sandbox',
/**
* Specify the max request time in seconds
*/
'http.ConnectionTimeOut' => 1000,
/**
* Whether want to log to a file
*/
'log.LogEnabled' => true,
/**
* Specify the file that want to write on
*/
'log.FileName' => storage_path() . '/logs/paypal.log',
/**
* Available option 'FINE', 'INFO', 'WARN' or 'ERROR'
*
* Logging is most verbose in the 'FINE' level and decreases as you
* proceed towards ERROR
*/
'log.LogLevel' => 'FINE'
),
);
第 5 步:创建路由
在这一步中,我们需要为贝宝支付创建路由。所以打开你的 routes/web.php 文件并添加以下路由。
routes/web.php
Route::get('paywithpaypal', array('as' => 'addmoney.paywithpaypal','uses' => 'AddMoneyController@payWithPaypal',));
Route::post('paypal', array('as' => 'addmoney.paypal','uses' => 'AddMoneyController@postPaymentWithpaypal',));
Route::get('paypal', array('as' => 'payment.status','uses' => 'AddMoneyController@getPaymentStatus',));
第 6 步:创建控制器
在这一点上,现在我们应该在这条路径 app/Http/Controllers/AddMoneyController.php 中创建新的控制器作为 AddMoneyController。此控制器将管理布局和支付 post 请求,因此 运行 生成新控制器的命令如下:
php artisan make:controller AddMoneyController
好的,现在在控制器文件中放入以下内容:
app/Http/Controllers/AddMoneyController.php
<?php
namespace App\Http\Controllers;
use App\Http\Requests;
use Illuminate\Http\Request;
use Validator;
use URL;
use Session;
use Redirect;
use Input;
/** All Paypal Details class **/
use PayPal\Rest\ApiContext;
use PayPal\Auth\OAuthTokenCredential;
use PayPal\Api\Amount;
use PayPal\Api\Details;
use PayPal\Api\Item;
use PayPal\Api\ItemList;
use PayPal\Api\Payer;
use PayPal\Api\Payment;
use PayPal\Api\RedirectUrls;
use PayPal\Api\ExecutePayment;
use PayPal\Api\PaymentExecution;
use PayPal\Api\Transaction;
class AddMoneyController extends HomeController
{
private $_api_context;
/**
* Create a new controller instance.
*
* @return void
*/
public function __construct()
{
parent::__construct();
/** setup PayPal api context **/
$paypal_conf = \Config::get('paypal');
$this->_api_context = new ApiContext(new OAuthTokenCredential($paypal_conf['client_id'], $paypal_conf['secret']));
$this->_api_context->setConfig($paypal_conf['settings']);
}
/**
* Show the application paywith paypalpage.
*
* @return \Illuminate\Http\Response
*/
public function payWithPaypal()
{
return view('paywithpaypal');
}
/**
* Store a details of payment with paypal.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function postPaymentWithpaypal(Request $request)
{
$payer = new Payer();
$payer->setPaymentMethod('paypal');
$item_1 = new Item();
$item_1->setName('Item 1') /** item name **/
->setCurrency('USD')
->setQuantity(1)
->setPrice($request->get('amount')); /** unit price **/
$item_list = new ItemList();
$item_list->setItems(array($item_1));
$amount = new Amount();
$amount->setCurrency('USD')
->setTotal($request->get('amount'));
$transaction = new Transaction();
$transaction->setAmount($amount)
->setItemList($item_list)
->setDescription('Your transaction description');
$redirect_urls = new RedirectUrls();
$redirect_urls->setReturnUrl(URL::route('payment.status')) /** Specify return URL **/
->setCancelUrl(URL::route('payment.status'));
$payment = new Payment();
$payment->setIntent('Sale')
->setPayer($payer)
->setRedirectUrls($redirect_urls)
->setTransactions(array($transaction));
/** dd($payment->create($this->_api_context));exit; **/
try {
$payment->create($this->_api_context);
} catch (\PayPal\Exception\PPConnectionException $ex) {
if (\Config::get('app.debug')) {
\Session::put('error','Connection timeout');
return Redirect::route('addmoney.paywithpaypal');
/** echo "Exception: " . $ex->getMessage() . PHP_EOL; **/
/** $err_data = json_decode($ex->getData(), true); **/
/** exit; **/
} else {
\Session::put('error','Some error occur, sorry for inconvenient');
return Redirect::route('addmoney.paywithpaypal');
/** die('Some error occur, sorry for inconvenient'); **/
}
}
foreach($payment->getLinks() as $link) {
if($link->getRel() == 'approval_url') {
$redirect_url = $link->getHref();
break;
}
}
/** add payment ID to session **/
Session::put('paypal_payment_id', $payment->getId());
if(isset($redirect_url)) {
/** redirect to paypal **/
return Redirect::away($redirect_url);
}
\Session::put('error','Unknown error occurred');
return Redirect::route('addmoney.paywithpaypal');
}
public function getPaymentStatus()
{
/** Get the payment ID before session clear **/
$payment_id = Session::get('paypal_payment_id');
/** clear the session payment ID **/
Session::forget('paypal_payment_id');
if (empty(Input::get('PayerID')) || empty(Input::get('token'))) {
\Session::put('error','Payment failed');
return Redirect::route('addmoney.paywithpaypal');
}
$payment = Payment::get($payment_id, $this->_api_context);
/** PaymentExecution object includes information necessary **/
/** to execute a PayPal account payment. **/
/** The payer_id is added to the request query parameters **/
/** when the user is redirected from paypal back to your site **/
$execution = new PaymentExecution();
$execution->setPayerId(Input::get('PayerID'));
/**Execute the payment **/
$result = $payment->execute($execution, $this->_api_context);
/** dd($result);exit; /** DEBUG RESULT, remove it later **/
if ($result->getState() == 'approved') {
/** it's all right **/
/** Here Write your database logic like that insert record or value in database if you want **/
\Session::put('success','Payment success');
return Redirect::route('addmoney.paywithpaypal');
}
\Session::put('error','Payment failed');
return Redirect::route('addmoney.paywithpaypal');
}
}
第 7 步:创建视图
在最后一步中,让我们创建 paywithpaypal.blade.php(resources/views/paywithpaypal.blade.php) 用于布局,我们将在此处编写设计代码以及通过 paypal 支付金额的表格,因此输入以下代码:
resources/views/paywithpaypal.blade.php
@extends('layouts.app')
@section('content')
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
@if ($message = Session::get('success'))
<div class="custom-alerts alert alert-success fade in">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true"></button>
{!! $message !!}
</div>
<?php Session::forget('success');?>
@endif
@if ($message = Session::get('error'))
<div class="custom-alerts alert alert-danger fade in">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true"></button>
{!! $message !!}
</div>
<?php Session::forget('error');?>
@endif
<div class="panel-heading">Paywith Paypal</div>
<div class="panel-body">
<form class="form-horizontal" method="POST" id="payment-form" role="form" action="{!! URL::route('addmoney.paypal') !!}" >
{{ csrf_field() }}
<div class="form-group{{ $errors->has('amount') ? ' has-error' : '' }}">
<label for="amount" class="col-md-4 control-label">Amount</label>
<div class="col-md-6">
<input id="amount" type="text" class="form-control" name="amount" value="{{ old('amount') }}" autofocus>
@if ($errors->has('amount'))
<span class="help-block">
<strong>{{ $errors->first('amount') }}</strong>
</span>
@endif
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-md-offset-4">
<button type="submit" class="btn btn-primary">
Paywith Paypal
</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
</div>
