我有这个 IPN 监听器脚本。我只是从 paypal 复制这个并稍微修改一下。
function ipn_listener()
{
$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";
}
// STEP 2: POST IPN data back to PayPal to validate
$ch = curl_init('https://www.sandbox.paypal.com/cgi-bin/webscr');
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $req);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_FORBID_REUSE, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: Close'));
// In wamp-like environments that do not come bundled with root authority certificates,
// please download 'cacert.pem' from [link removed] and set
// the directory path of the certificate as shown below:
curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
if( !($res = curl_exec($ch)) ) {
// error_log("Got " . curl_error($ch) . " when processing IPN data");
echo "Got " . curl_error($ch) . " when processing IPN data";
curl_close($ch);
exit;
}
curl_close($ch);
// STEP 3: Inspect IPN validation result and act accordingly
switch($res){
case "VERIFIED":
echo 'verified';
break;
case "INVALID":
echo 'invalid';
break;
default:
// any other case (such as no response, connection timeout...)
}
}
每次我调用那个监听器它总是返回无效。我不明白这个问题..这只是我第一次使用 IPN..需要帮助我想显示 IPN 消息。
谢谢，
最佳答案
你是在调用那个监听器还是 Paypal 调用的？ 此脚本应在传输发生后执行。
如果我是对的，那么您应该在您的 PayPal 配置文件中指定此文件/函数的 url 并再次检查您的 html 代码，以便 POST 操作正确。关于此检查更多这里 https://developer.paypal.com/webapps/developer/docs/classic/paypal-payments-standard/integration-guide/buynow_buttons/
