为什么我的PayPal IPN脚本失败? [英] Why is my PayPal IPN script failing?

问题描述

我正在开发一种轻量级的电子商务解决方案，该解决方案使用 PayPal 作为支付网关.但是，我的IPN回调不断返回INVALID响应.我什至尝试使用 PayPal 提供的示例PHP脚本:

I'm developing a lightweight e-commerce solution that uses PayPal as the payment gateway. However, my IPN callback is constantly returning an INVALID response. I even tried using the sample PHP script provided by PayPal:

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

foreach ($_POST as $key => $value) {
  $value = urlencode(stripslashes($value));
  $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];

if (!$fp) {
  // HTTP ERROR
}
else {
  fputs ($fp, $header . $req);
  while (!feof($fp)) {
    $res = fgets ($fp, 1024);
    if (strcmp ($res, "VERIFIED") == 0) {
      // check the payment_status is Completed
      // check that txn_id has not been previously processed
      // check that receiver_email is your Primary PayPal email
      // check that payment_amount/payment_currency are correct
      // process payment
    }
    else if (strcmp ($res, "INVALID") == 0) {
      // log for manual investigation
    }
  }
  fclose ($fp);
}

但是正如我所说，我一直收到INVALID响应.实际上，这是我使用将响应写入日志文件的PHP类得到的响应:

But as I say, I keep getting an INVALID response. This is in fact the response I get using a PHP class that writes the response to a log file:

[2011-06-02 19:18:49] - FAIL: IPN Validation Failed.
IPN POST data from PayPal:

这是来自官方的 PayPal IPN测试工具.因此，在 PayPal 的示例代码和测试工具之间发生的某种情况导致我的脚本失败.有人有想法吗?

This is from the official PayPal IPN test tool. So something between PayPal's sample code and test tool is causing my script to fail. Any one have any ideas?

推荐答案

您的html/php页面的编码是什么? (charset = windows-1252)吗?

what is encoding of your html/php page ? (charset=windows-1252) ?
