我的 IP 一直返回 INVALID

Question

我需要验证我的 IPN 消息，但它总是返回 INVALID

我的 IPN

cmd=_notify-validate&mc_gross=76.00&protection_eligibility=Ineligible&payer_id=5F68MJE8GYSFL&tax=0.00&payment_date=23%3A01%3A49%2BNov%2B04%2C%2B2016%2BPDT&payment_status=Completed&charset=UTF-8&first_name=Buyer%2BBrij&mc_fee=2.78¬ify_version=3.8&custom=&payer_status=verified&business=brij.mohan-softo-facilitator%40softobiz.com&quantity=1&payer_email=brij.mohan-softo-buyer%40softobiz.com&verify_sign=AFcWxV21C7fd0v3bYYYRCpSSRl31A2CY4u8sMD28t8rYIS1l.8kZv8Om&txn_id=2M448997GH018883K&payment_type=instant&last_name=Softobiz&receiver_email=brij.mohan-softo-facilitator%40softobiz.com&payment_fee=&receiver_id=UUEGZHZ6WXVCG&txn_type=web_accept&item_name=Hire%2BGuard&mc_currency=GBP&item_number=&residence_country=GB&test_ipn=1&handling_amount=0.00&transaction_subject=&payment_gross=&shipping=0.00&merchant_return_link=click%2Bhere&auth=AtmNfVa7oX-lTpjA7qqntT12AX085EG9DbyOgtWjgrr1Qm7nc3hfy442zorp44VGQ59KWCXZbifuNdzDp.A3n.w&form_charset=UTF-8

然后我在这里查看了 IPN

1.) https://www.sandbox.paypal.com/webscr

2.) 我的帐户-> 历史记录-> IPN 历史记录-> 即时付款通知 (IPN) 详细信息

下面是IPN消息

 mc_gross=76.00&protection_eligibility=Ineligible&payer_id=5F68MJE8GYSFL&tax=0.00&payment_date=23:01:49 Nov 04, 2016 PDT&payment_status=Completed&charset=UTF-8&first_name=Buyer Brij&mc_fee=2.78&notify_version=3.8&custom=&payer_status=verified&business=brij.mohan-softo-facilitator@softobiz.com&quantity=1&verify_sign=A--8MSCLabuvN8L.-MHjxC9uypBtA5uyYRfhtvRLzxfTdTg29AzcboEl&payer_email=brij.mohan-softo-buyer@softobiz.com&txn_id=2M448997GH018883K&payment_type=instant&last_name=Softobiz&receiver_email=brij.mohan-softo-facilitator@softobiz.com&payment_fee=&receiver_id=UUEGZHZ6WXVCG&txn_type=web_accept&item_name=Hire Guard&mc_currency=GBP&item_number=&residence_country=GB&test_ipn=1&handling_amount=0.00&transaction_subject=&payment_gross=&shipping=0.00&ipn_track_id=3ab983572cde

我在谷歌上进行了研究，据我所知，除了这一点，一切似乎都很好

验证您对测试 IPN 消息的响应是否包含与测试消息完全相同的变量和值，并且它们与测试消息中的顺序相同。最后，验证原始变量前面是否有 cmd=_notify-validate 变量。

可能我无法理解我如何以相同的顺序和相同的值发送 ipn，因此教皇可以验证我的 IPN。当我将我的 ipn 与原始 ipn 进行比较时，您会注意到 ¬ify_version=3.8 和原始 ipn 消息 notify_version=3.8

我正在使用这个 paypal IPN 验证类

这是我的贝宝表格

此代码片段已被验证可以正常工作。准备好后确保将其切换到实时模式。这直接来自 PayPal 的 IPN 文档。

<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);


// Send an empty HTTP 200 OK response to acknowledge receipt of the notification
header('HTTP/1.1 200 OK');

// read the IPN notification from PayPal and add the 'cmd' parameter to the beginning of the acknowledgement you will send back
$req = 'cmd=_notify-validate';

// Loop through the notification name-value pairs
foreach ($_POST as $key => $value) {
    // Encode the values
    $value = urlencode(stripslashes($value));
    // Add the name-value pairs to the acknowledgement
    $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.1\r\n";

// Set up other acknowledgement request headers
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

// If testing on Sandbox use:
$header .= "Host: www.sandbox.paypal.com:443\r\n";
// For live servers use $header .= "Host: www.paypal.com:443\r\n";

// Open a socket for the acknowledgement request
// If testing on Sandbox use:
$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);
// For live servers use $fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

// Send the HTTP POST request back to PayPal for validation
fputs($fp, $header . $req);


//Do any commands with POST variables here, for ex:
echo $_POST['payment_status'];
