Question

几个小时后，下面的脚本工作得非常好，突然间它停止了工作。

我没有改变任何事情。

是否有任何可能阻止其正常工作的错误？

<?php

// STEP 1: read POST data

// Reading POSTed data directly from $_POST causes serialization issues with array data in the POST.
// Instead, read raw POST data from the input stream.
$raw_post_data = file_get_contents('php://input');
$raw_post_array = explode('&', $raw_post_data);
$myPost = array();
foreach ($raw_post_array as $keyval) {
    $keyval = explode ('=', $keyval);
    if (count($keyval) == 2)
        $myPost[$keyval[0]] = urldecode($keyval[1]);
}
// read the IPN message sent from PayPal and prepend 'cmd=_notify-validate'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
    $get_magic_quotes_exists = true;
}
foreach ($myPost as $key => $value) {
    if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1) {
        $value = urlencode(stripslashes($value));
    } else {
        $value = urlencode($value);
    }
    $req .= "&$key=$value";
}

    // process payment

Answer 1

检查您的PayPal帐户中的IPN历史记录，查看IPN是否实际上已发送，以及回复的响应。如果它显示它们已被发送并包含200响应，那么这意味着您的脚本正在被击中并成功完成。在这种情况下，您需要检查脚本的逻辑，看看它为什么没有按照您的想法进行操作。

如果它根本不发送，您需要仔细检查PayPal帐户中的IPN配置或付款请求中使用的通知URL。

如果它显示它正在发送但是获得200响应以外的其他内容意味着您的IPN脚本失败。您可以检查Web服务器日志，以获取有关错误确切内容的详细信息并将其解决。

似乎发送无关数据

我正在记录paypal对验证的响应，它会在我记录的重要位上发送一些内容

Content-Type：text / html;字符集= UTF-8 -空行- 8 VERIFIED 0
