AppStore 內購驗證的方法

標籤：style   blog   class   c   code   java   

AppStore增加了驗證內購(In App Purchasement)的方法, 就是蘋果提供一個url地址, 開發測試用:

https://sandbox.itunes.apple.com/verifyReceipt

產品用:

https://buy.itunes.apple.com/verifyReceipt

當購買成功時, 會得到蘋果返回的一個收據(receipt), 蘋果推薦的方法是將收據發給開發人員的server, 由server像上述地址post http訊息, 進行驗證, 蘋果將結果返回.到底是真正的購買還是虛假的購買.

沒有自己server的小夥伴可以用app進行發送, 代碼如下.

#define ITMS_SANDBOX_VERIFY_RECEIPT_URL     @"https://sandbox.itunes.apple.com/verifyReceipt"#pragma mark - VerifyFinishedTransaction-(void)verifyFinishedTransaction:(SKPaymentTransaction *)transaction{    if(transaction.transactionState == SKPaymentTransactionStatePurchased){        NSString *transactionIdentifier =  transaction.transactionIdentifier;        NSData *transactionReceipt  = transaction.transactionReceipt;        //將transactionIdentifer和加密後的transactionReceipt資料發送給server端                NSString* receipent = [NSString stringWithFormat:@"%s", transactionReceipt.bytes];                NSLog(@"receipent = %@", receipent);                // 在app上做驗證, 僅用於測試        NSString *payload = [NSString stringWithFormat:@"{\"receipt-data\" : \"%@\", \"password\" : \"%@\"}",                             receipent, transactionIdentifier];        NSData *payloadData = [payload dataUsingEncoding:NSUTF8StringEncoding];        NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:ITMS_SANDBOX_VERIFY_RECEIPT_URL]];        [request setHTTPMethod:@"POST"];        [request setHTTPBody:payloadData];        NSError* err;        NSURLResponse *theResponse = nil;        NSData *data=[NSURLConnection sendSynchronousRequest:request                                           returningResponse:&theResponse                                                       error:&err];        NSError *jsonParsingError = nil;        NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&jsonParsingError];        NSLog(@"%@", dict);        NSLog(@"done");        }}
