Question

我有一个listener.php和一个普通的表格，我的客户用paypal支付。我想知道付款，所以我想使用paypal的IPN。

如果我测试沙箱中的skript，我已经验证了。所以我想上线，所以我将地址更改为https://www.paypal.com/cgi-bin/webscr。

如果我现场测试，我每次都会失效。

我的代码：

listener.php：

＆＃13;

<?php
error_reporting(e_all);
// CONFIG: Enable debug mode. This means we'll log requests into 'ipn.log' in the same directory.
// Especially useful if you encounter network errors or other intermittent problems with IPN (validation).
// Set this to 0 once you go live or don't require logging.
define("DEBUG", 1);
// Set to 0 once you're ready to go live
define("USE_SANDBOX", 0);
define("LOG_FILE", "./ipn.log");
// Read POST data
// reading posted data directly from $_POST causes serialization
// issues with array data in POST. Reading raw POST data from input stream instead.
$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]] = rawurldecode($keyval[1]);
}
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
if(function_exists('get_magic_quotes_gpc')) {
	$get_magic_quotes_exists = true;
}
foreach ($_POST as $key => $value) {
	$value = rawurlencode(stripslashes($value));
	$value = preg_replace('/(.*[^%^0^D])(%0A)(.*)/i','${1}%0D%0A${3}',$value);// IPN fix
	$req .= "&$key=$value";
}

// Post IPN data back to PayPal to validate the IPN data is genuine
// Without this step anyone can fake IPN data
if(USE_SANDBOX == true) {
	$paypal_url = "https://www.sandbox.paypal.com/cgi-bin/webscr";

curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');

$tokens = explode("\r\n\r\n", trim($res));

if (strcmp ($res, "VERIFIED") == 0) {
