[英]PayPal IPN returns Invalid
我有一個用 PHP 編寫的 PayPal IPN 腳本,但無論我嘗試什么,我都無法讓它工作。
PayPal 使用 PayPal 沙箱和 PayPal IPN 模擬器返回“無效”。 我還沒有現場嘗試過,但它可能會返回相同的結果。
<?php
///
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
// Are we using magic quotes?
$get_magic_quotes_exists = false;
if(function_exists('get_magic_quotes_gpc')){
$get_magic_quotes_exists = true;
}
foreach($_POST as $key => $value){
// Handle escape characters, which depends on setting of magic quotes
if($get_magic_quotes_exists == true && get_magic_quotes_gpc() == 1){
$value = urlencode(stripslashes($value));
}else{
$value = urlencode($value);
}
if($get_magic_quotes_exists && get_magic_quotes_gpc() == 1){
$req .= '&' . $key . '=' . urlencode(stripslashes(html_entity_decode($value, ENT_COMPAT, 'windows-1252')));
$dc .= '&' . $key . '=' . urlencode(stripslashes(html_entity_decode($value, ENT_COMPAT, 'windows-1252')));
$emailtext .= "\n" . $key . "=" . urlencode(stripslashes(html_entity_decode($value, ENT_COMPAT, 'windows-1252')));
}else{
$req .= '&' . $key . '=' . urlencode(html_entity_decode($value, ENT_COMPAT, 'windows-1252'));
$dc .= '&' . $key . '=' . urlencode(html_entity_decode($value, ENT_COMPAT, 'windows-1252'));
$emailtext .= "\n" . $key . "=" . urlencode(html_entity_decode($value, ENT_COMPAT, 'windows-1252'));
}
}

$fp = fsockopen('www.sandbox.paypal.com', 80, $errno, $errstr, 30);*/

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/x-www-form-urlencoded", "Content-Length: " . strlen($req)));

$res = curl_exec($ch);
if(curl_error($ch)) {
$last_error = 'Could not connect to CURL';
}
curl_close($ch);
// Write to log...
$myFile = "log.txt";
$fh = fopen($myFile, 'w');
$stringData = "IPN REQUEST\n\n$req";
fwrite($fh, $stringData);
$stringData = "\n\nIPN RESPONSE:\n\n$res";
fwrite($fh, $stringData);
fclose($fh);
if(strcmp($res, 'VERIFIED') == 0){
// check the payment_status is Completed
if($payment_status != 'Completed'){
$last_error = "Payment was not completed.";
//exit($last_error);
}
我已經嘗試過 CURL 和 Fsockopen。 OpenSSL 在服務器上啟用。
以下是發回 PayPal 的數據示例:
cmd=_notify-validate&test_ipn=1&payment_type=instant&payment_date=12%253A06%253A49%2BAug%2B14%252C%2B2011%2BPDT&payment_status=Completed&address_status=confirmed&payer_status=verified&first_name=Peter&last_name=Anderson&payer_email=paypal2.test%2540gmail.com&payer_id=TESTBUYERID01&address_name=John%2BSmith&address_country=United%2BStates&address_country_code=US&address_zip=95131&address_state=CA&address_city=San%2BJose&address_street=123%252C%2Bany%2Bstreet&business=dr.pa%2540custcarecentral.com&receiver_email=paypal.test%2540custcarecentral.com&receiver_id=TESTSELLERID1&residence_country=US&item_name=something&item_number=1&quantity=1&shipping=0&tax=0&mc_currency=USD&mc_fee=0&mc_gross=9.95&mc_gross_1=9.95&txn_type=web_accept&txn_id=49814196¬ify_version=2.1&custom=xyz123&charset=windows-1252&verify_sign=A6PXLu.ocjeCd4T66jio.zEQRv65AD4orMH3FTVR7QibqBGYTnYA8ToF
我試過的 Fsock 在另一台服務器上工作,但不是這個。
誰能幫我? 我真的開始對此失去耐心了。
提前致謝
您可能想嘗試PHP-PayPal-IPN 。 它非常簡單,並且通過一些非常容易理解的錯誤處理來處理發布到 PayPal 的問題。 它允許您選擇 SSL/HTTP 和 fsockopen/cURL。
您的代碼將如下所示:
ini_set('log_errors', true);
ini_set('error_log', dirname(__FILE__).'/ipn_errors.log');
include('ipnlistener.php');
$listener = new IpnListener();
$listener->use_sandbox = true;
try {
$verified = $listener->processIpn();
} catch (Exception $e) {
error_log($e->getMessage());
exit(0);
}
if ($verified) {
// TODO: Implement additional fraud checks and MySQL storage
mail('YOUR EMAIL ADDRESS', 'Valid IPN', $listener->getTextReport());
} else {
// manually investigate the invalid IPN
mail('YOUR EMAIL ADDRESS', 'Invalid IPN', $listener->getTextReport());
}
您將檢查錯誤日志中是否存在硬錯誤(例如來自 PayPal 的無效 HTTP 響應代碼)和您的 email 以了解工作 IPN。 您也可以只查看一些想法的來源。
我對你使用 html_entity_decode() 有點好奇。 您正在運行什么類型的服務器?
