I am receiving the following from a PayPal IPN script. Is it evident from the following what is causing the IPN transaction to fail? If not, how can I investigate the problem further?

任何使用 Micah Carrick 的 PHP Paypal IPN 集成类并遇到相同问题的人：IPN 变量和值必须以 cmd=_notify-validate 开头。在 paypal.class.php 文件中正好相反。

因此，只需将$post_string = '';第 179 行中的替换为
$post_string="cmd=_notify-validate";
replace
$post_string .= $field.'='.urlencode(stripslashes($value)).'&';

在第 181 行$post_string .= '&' . $field.'='.urlencode(stripslashes($value));

然后在第 184 行删除$post_string.="cmd=_notify-validate";，你的问题应该得到解决。

您是否尝试过IPN 测试工具来调查问题？

您可以使用它来重现您提交的表单并查看是否获得一致的结果。

如果您准确指定失败的上下文，您可能会得到更好的答案。

要连接到沙盒 Paypal，请使用此行：

$fp = fsockopen ('ssl://www.sandbox.paypal.com', 443, $errno, $errstr, 30);

并不是 ：$fp = fsockopen($url_parsed['host'],"80",$err_num,$err_str,30);

并且响应 IPN 发送单词“ VERIFIED ”

如果您正在通过 SSL 测试 Paypal IPN，则必须ssl://www.sandbox.paypal.com在port 443

@Dominik，这似乎也解决了我的问题！我碰巧在使用Md Emran Hasan 的 PHP 类。并用这个问题把我的头发扯掉了大约一个星期！

所以我的编辑看起来像这样......$postString .="cmd=_notify-validate"; //曾经在while循环之后！这段代码被包装在一个validateIPN函数中。

    $postString .= "cmd=_notify-validate"; // append ipn command

    foreach ($_POST as $field=>$value)
    {
        $this->ipnData["$field"] = $value;
        $postString .= '&' . $field .'=' . urlencode(stripslashes($value));
    }
