问题描述
我正在尝试使用PHP验证Windows Store的收据.
I am trying to verify receipt from Windows Store using PHP.
我正在使用以下代码:

我正在关注此链接 .但是我总是输出不好"的东西.
I am following this link. But I am always getting "bad" as output.
有人可以告诉我我在做什么错吗?
Can somebody tell me what I am doing wrong here?
谢谢
推荐答案
我设法使用 xmlseclibs 库. Windows应用商店没有太大区别.
I managed to verify WP8 IAP receipt using xmlseclibs library. Windows Store is not much different.
此外，您需要启用php curl.
Also, you need php curl enabled.
do {
$doc = new DOMDocument();
$xml = $_POST['receipt_data']; // your receipt xml here!
// strip unwanted chars - IMPORTANT!!!
$xml = str_replace(array("\n","\t", "\r"), "", $xml);
//some (probably mostly WP8) receipts have unnecessary spaces instead of tabs
$xml = preg_replace('/\s+/', " ", $xml);
$xml = str_replace("> <", "><", $xml);
$doc->loadXML($xml);
$receipt = $doc->getElementsByTagName('Receipt')->item(0);
$certificateId = $receipt->getAttribute('CertificateId');
$ch = curl_init("https://lic.apps.microsoft.com/licensing/certificateserver/?cid=$certificateId");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$publicKey = curl_exec($ch);
$errno = curl_errno($ch);
$errmsg = curl_error($ch);
curl_close($ch);
if ($errno != 0) {
$verifyFailed = true;
break;
}
// Verify xml signature
require('./xmlseclibs.php');
$objXMLSecDSig = new XMLSecurityDSig();
$objDSig = $objXMLSecDSig->locateSignature($doc);
if (!$objDSig) {
$verifyFailed = true;
break;
}
try {
$objXMLSecDSig->canonicalizeSignedInfo();
$retVal = $objXMLSecDSig->validateReference();
if (!$retVal) {
throw new Exception("Error Processing Request", 1);
}
$objKey = $objXMLSecDSig->locateKey();
if (!$objKey) {
throw new Exception("Error Processing Request", 1);
}
$key = NULL;
$objKeyInfo = XMLSecEnc::staticLocateKeyInfo($objKey, $objDSig);
if (! $objKeyInfo->key && empty($key)) {
$objKey->loadKey($publicKey);
}
if (!$objXMLSecDSig->verify($objKey)) {
throw new Exception("Error Processing Request", 1);
}
} catch (Exception $e) {
$verifyFailed = true;
break;
}
$productReceipt = $doc->getElementsByTagName('ProductReceipt')->item(0);
$prodictId = $productReceipt->getAttribute('ProductId');
$purchaseDate = $productReceipt->getAttribute('PurchaseDate');
} while(0);
if ($verifyFailed) {
// invalid receipt
} else {
// valid receipt
}
如果您要处理WP8应用程序内购买，则xml中的CertificateId可能看起来像这样A656B9B1B3AA509EEA30222E6D5E7DBDA9822DCD.但是以下链接显示404错误:
If you are dealing with WP8 in-app purchase, the CertificateId in the xml may look like this A656B9B1B3AA509EEA30222E6D5E7DBDA9822DCD. But the following link gives 404 error:
https://lic.apps.microsoft.com/licensing/certificateserver/?cid=A656B9B1B3AA509EEA30222E6D5E7DBDA9822DCD
因此，您无法获得带有curl的证书.取而代之的是，将卷曲部分替换为:
So you cannot get the certificate with curl. Instead, replace the curl part with this:
$publicKey = <<<EOT

EOT;
(证书来自 MSDN示例代码.我将其转换为PEM格式.)
(The certificate is from MSDN sample code. I converted it to PEM format.)
现在可以使用XD！
