我正在尝试在服务器端使用收据验证。一切都很好,但有时候出现奇怪的问题:验证10次都没问题,但第11次就会出现21002错误。我不知道该怎么办。有时候在启动应用程序后第一次验证收据时会出现21002错误。
应用程序端:
func validateReceipt(productID: String) {
let receipt = NSData(contentsOfURL: NSBundle.mainBundle().appStoreReceiptURL!)!
let receiptdata = receipt.base64EncodedStringWithOptions(NSDataBase64EncodingOptions(rawValue: 0))
let request = NSMutableURLRequest(URL: NSURL(string: "my_server_url")!)
let session = NSURLSession.sharedSession()
request.HTTPMethod = "POST"
request.HTTPBody = receiptdata.dataUsingEncoding(NSUTF8StringEncoding)
let task = session.dataTaskWithRequest(request, completionHandler: {data, response, error -> Void in
let json = try! NSJSONSerialization.JSONObjectWithData(data!, options: .MutableLeaves) as? NSDictionary
if (error != nil) {
print(error!.localizedDescription)
let jsonStr = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Error could not parse JSON: '\(jsonStr)'")
}
else {
if let parseJSON = json {
if String(parseJSON["status"]! == "ok" {
//do something
print("Validate OK")
}else{
print("Validate NOK")
}
}
else {
let jsonStr = NSString(data: data!, encoding: NSUTF8StringEncoding)
print("Receipt Error: \(jsonStr)")
}
}
})
task.resume()
}
服务器端的PHP脚本:
function getReceiptData($receipt)
{
$endpoint = 'https://sandbox.itunes.apple.com/verifyReceipt';
$ch = curl_init($endpoint);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $receipt);
$response = curl_exec($ch);
$errno = curl_errno($ch);
$errmsg = curl_error($ch);
curl_close($ch);
$msg = $response.' - '.$errno.' - '.$errmsg;
echo $response;
}
foreach ($_POST as $key=>$value){
$newcontent .= $key.' '.$value;
}
$new = trim($newcontent);
$new = trim($newcontent);
$new = str_replace('_','+',$new);
$new = str_replace(' =','==',$new);
if (substr_count($new,'=') == 0){
if (strpos('=',$new) === false){
$new .= '=';
}
}
$new = '{"receipt-data":"'.$new.'"}';
$info = getReceiptData($new);
我所做的每一件事情都是基于这个例子:http://www.brianjcoleman.com/tutorial-receipt-validation-in-swift/
因此,有时候我感觉应用程序将错误的收据发送到服务器端,PHP脚本无法解析它,导致我收到21002错误状态。有什么建议吗?
json_encode(["receipt-data" => $new])
