Answer 1

您是否尝试过IPN test tool来调查此问题？

您可以使用它来重现您提交的表单，看看您是否获得一致的结果。

如果您确切地指定它失败的上下文，您可能会得到更好的答案。

Answer 2

任何人使用Micah Carrick的PHP Paypal IPN集成课程并遇到同样的问题： IPN变量和值必须以cmd = _notify-validate开头。在paypal.class.php文件中，恰恰相反。

所以，只需用第179行替换$post_string = ''; $post_string="cmd=_notify-validate";
更换
$post_string .= $field.'='.urlencode(stripslashes($value)).'&';

第{181}行$post_string .= '&' . $field.'='.urlencode(stripslashes($value));

然后在第184行删除$post_string.="cmd=_notify-validate";，您的问题就应该解决了。

Answer 3

要连接到沙盒Paypal，请使用以下行：

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

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

并且响应IPN发送单词“已验证”

如果您通过SSL测试Paypal IPN，则必须使用ssl://www.sandbox.paypal.com上的port 443

Answer 4

@Dominik，这似乎也解决了我的问题！我碰巧使用Md Emran Hasan's PHP class。用这个问题彻底撕掉了我的头发一个星期！

所以我的编辑看起来像这样...... $postString .="cmd=_notify-validate"; //曾经在while循环之后！此代码包含在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));
    }

是什么导致我的PayPal IPN脚本失败？
