Question

您好我正在尝试使用laravel 5实现paypal结帐，但是我的IPN监听器根本没有收听支付通知。

我没有创建开发者帐户或其他任何东西。我有我的商家ID并发送其他详细信息，如返回网址，通知网址如下。

  <form method="post" action="https://www.paypal.com/cgi-bin/webscr" class="paypal-button" target="_top">

    <div class="hide" id="errorBox"></div>
    <input type="hidden" name="button" value="subscribe">
    <input type="hidden" name="item_name" value="xyz Membership">
    <input type="hidden" name="quantity" value="1">
    <input type="hidden" name="amount" value="9">
    <input type="hidden" name="currency_code" value="USD">
    <input type="hidden" name="shipping" value="0">
    <input type="hidden" name="tax" value="0">
    <input type="hidden" name="notify_url" value="https://members.xyz.com/ipn">
    <input type="hidden" name="return" value="https://members.xyz.com">
    <input type="hidden" name="cancel" value="https://members.xyz.com">
    <input type="hidden" name="size" value="small">
    <input type="hidden" name="p3" value="1">
    <input type="hidden" name="t3" value="M">
    <input type="hidden" name="custom" value="410">
    <input type="hidden" name="cmd" value="_xclick-subscriptions">
    <input type="hidden" name="a3" value="9">
    <input type="hidden" name="business" value="xxxxxxxxx">
    <input type="hidden" name="bn" value="JavaScriptButton_subscribe">
    <input type="hidden" name="env" value="www">
    <button type="submit" class="paypal-button small">Monthly</button>

   </form>

请在下面找到我的ipn代码。

  Route::post('ipn', function() {


     $payment_settings = PaymentSetting::first();

     $plugin_data = (object) array_build(PluginData::where('plugin_slug', 'paypal')->get(), function($key, $data) {
    return array($data->key, $data->value);
});

     header('HTTP/1.1 200 OK');

     $sandbox = 'sandbox.';
     if($payment_settings->live_mode)
         $sandbox = '';

     $receiver_email   = Input::get('receiver_email');
     $txn_type         = Input::get('txn_type');
     $payment_status   = Input::get('payment_status');

    }
}


if($result == 'VERIFIED' && strtolower($receiver_email) == strtolower($plugin_data->paypal_merchant_id)) {

你问题中的评论是一个好的开始。您可能需要检查您的IPN侦听器。您可以设置日志以保存对特定日志文件的调用，以便您查看IPN进入时发生的情况。

这是IPN的基本集成指南： https://developer.paypal.com/docs/classic/products/instant-payment-notification/

以下是一些示例代码，说明如何处理IPN通知并发送响应： https://developer.paypal.com/docs/classic/ipn/ht_ipn/

识别您的PayPal IPN监听器： https://developer.paypal.com/docs/classic/ipn/integration-guide/IPNSetup/

如果您在这些文档中找不到答案，可以使用PayPal Merchant技术支持打开一张票： https://ppmts.custhelp.com/

他们可以帮助您查看您的IPN消息和服务器的响应。
