Question

最近出现了这个问题：我无法从paypal沙箱（IPN）获得回复。

我使用以下代码：

import requests
params = {} #all params paypal sent via IPN, empty here for sake of brevity
params['cmd'] = "_notify-validate"
r = requests.post("https://www.sandbox.paypal.com/cgi-bin/webscr", params = params)

这将返回一条错误消息，说明＆＃34;由对等方重置连接＆＃34;

请注意，此代码之前工作正常，如果我使用实时网站Paypal网址而不是沙盒，那么我仍然会收到响应而不是连接错误。

任何人都可以验证这是Paypal的问题吗？我的代码都没有改变，但是从昨天开始，我使用沙箱的测试都不再适用。

PayPal目前在Sandbox环境中没有遇到IPN问题。我已经测试过并且无法重新描述所描述的问题。您可以尝试测试下面的代码，看看您是否有相同的结果？

＆＃13;

<?php

// change email from xxx@xxxx.com to a valid one.

// read the post from PayPal system and add 'cmd'
if($_SERVER['REQUEST_METHOD']!="POST") die("No data");
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate
$url=(!isset($_POST['test_ipn'])) ? 'https://www.paypal.com/cgi-bin/webscr' : 'https://www.sandbox.paypal.com/cgi-bin/webscr';

    $curl_result=$curl_err='';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded", "Content-Length: " . strlen($req)));
    curl_setopt($ch, CURLOPT_HEADER , 0);  
    curl_setopt($ch, CURLOPT_VERBOSE, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($ch, CURLOPT_TIMEOUT, 30);
    $curl_result = @curl_exec($ch);
    $curl_err = curl_error($ch);
    curl_close($ch);

//are we verified? If so, let's process the IPN
if (strpos($curl_result, "VERIFIED")!==false)
{
//do your IPN stuff here
$mail_From = "From: IPN@domain.com";  // enter an email address alias here example ipn@fiercepc.co.uk please note this does not need to be a real email address
$mail_To = "email@domain.com";  //enter the email address you want to receive the email at
$mail_Subject = "VERIFIED IPN";
$mail_Body = $req;

foreach ($_POST as $key => $value){
$emailtext .= $key . " = " .$value ."\r\n\r\n";
}

mail($mail_To, $mail_Subject, $emailtext . "\r\n\r\n" . $mail_Body, $mail_From);
}
else{
$mail_From = "From: IPN@domain.com";
$mail_To = "email@domain.com";
$mail_Subject = "INVALID IPN";
$mail_Body = $req;

$emailtext = "you didn't get anything";
mail($mail_To, $mail_Subject, $emailtext . "\r\n\r\n" . $mail_Body, $mail_From);
}

?>

或者转到GitHub存储库以查找更多IPN样本。

这实际上是我的Python代码的一个问题。奇怪的是，我没有更改请求模块，但它停止使用相同的代码。

一旦我改为通过'data'参数发送IPN变量，而不是'params'，那么我就能收到正常的响应。

r = requests.post("https://www.sandbox.paypal.com/cgi-bin/webscr", data = params)

Sandbox Paypal IPN没有发送响应，适用于现场网站Paypal
