Question

我有以下CakePHP 2.x代码

<?php
App::uses('HttpSocket', 'Network/Http');

class PaypalUtility
{
    public static function isValidPayPalIPN( $data )
    {
        $result = false;
        $HttpSocket = new HttpSocket();
        $data[ "cmd" ] = "_notify-validate";
        $response = $HttpSocket->post( 'https://www.sandbox.paypal.com/cgi-bin/webscr', $data );

        if( trim( $response->body ) == "VERIFIED" )
        {
            $result = true;
        }

        return $result;
    }
}
?>

以下代码在我的控制器中

debug( PaypalUtility::isValidPayPalIPN( $this->getTestIPN() ) );
debug( PaypalUtility::isValidPayPalIPN( $this->getRealIPN() ) );

public function getRealIPN()
{
    return json_decode

已从realIPN功能中删除字段以保护买方的隐私。

以下是代码的输出： http://i.imgur.com/9xcM7hL.png

您会注意到来自IPN模拟器的测试IPN是有效的，但我作为请求捕获的真实数据被确定为无效。（我还验证了PayPal正在为验证realipn返回'INVALID'。

有谁知道我的isValidPayPalIPN函数有什么问题，或者为什么真正的IPN数据没有被验证？我必须想象与通知版本有关。

Answer 1

该函数是硬编码https://www.sandbox.paypal.com作为端点。当你上线，必须切换到www.paypal.com。否则，它正在验证错误的服务器，因此您确实会失效。

处理它的最佳方法是根据某处的配置文件动态填充该端点值。

PayPal IPN未经过验证
