StoreKit验证错误21002:收据数据属性中的数据格式错误

问题描述

在iPhone 4/iOS 4设备上，沙盒App Store在验证过程中报告了此错误:

On a iPhone 4/iOS 4 device, sandbox App Store is reporting this error during verification:

在iPhone 5/iOS 6设备上，相同的代码有效(状态== 0，已返回收据)，没有任何问题.

On a iPhone 5/iOS 6 device, the same code works (status == 0, receipt returned) without any problems.

我已经重新启动设备，确保注销了Apple ID，甚至已经创建了一个新的测试用户帐户.结果相同.有什么想法吗?

I've restarted the device, made sure the Apple ID is logged out, even made a new test user account. Same result. Any ideas?

推荐答案

此错误表示您创建的要发送用于验证的JSON对象的格式不正确.

This Error means the JSON Object that you have created to send for verification is not in correct format.

{
    "receipt-data" : "(receipt bytes here)"
}

因此，我的建议是在iPhone 4/iOS 4上进行调试.以防万一，如果您正在使用Json Framework创建JSON对象(用于收据验证)，则它仅适用于iOS 5.0及更高版本.以上.

So My suggestion is to Debug the same on iPhone 4/iOS 4. In case, you are Using Json Framework to create JSON object (for receipt validation) it will work only with iOS 5.0 & above.

添加我已经实施了几个月的代码，我使用SBJson编写了N个解析.

Adding Code I had Implemented a few months I Used SBJson to write N parse.

NSString *base64TxReceiptStr=[NSData Base64Encode:transaction.transactionReceipt];

SBJsonWriter *writer = [[SBJsonWriter alloc] init];
NSDictionary *command = [NSDictionary dictionaryWithObjectsAndKeys:
                         base64TxReceiptStr, @"receipt-data",
                         nil];
NSString *jsonString = [writer stringWithObject:command];
NSData *requestBody=[jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *txReceiptVerificationRequest=[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]];
[txReceiptVerificationRequest setHTTPBody:requestBody];
[txReceiptVerificationRequest setHTTPMethod:@"POST"];

NSURLResponse *response=nil;
NSError *error=nil;
NSData *responseData=[NSURLConnection sendSynchronousRequest:txReceiptVerificationRequest returningResponse:&response error:&error];
NSString * receivedString=[[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];


SBJsonParser *parser = [[SBJsonParser alloc] init];
NSDictionary *aobject =[parser objectWithString:receivedString];`
