Generate JSON object with transactionReceipt
- by Carlos
Hi,
I've been the past days trying to test my first in-app purchse iphone application. Unfortunately I can't find the way to talk to iTunes server to verify the transactionReceipt.
Because it's my first try with this technology I chose to verify the receipt directly from the iPhone instead using server support. But after trying to send the POST request with a JSON onbject created using the JSON api from google code, itunes always returns a strange response (instead the "status = 0" string I wait for).
Here's the code that I use to verify the receipt:
- (void)recordTransaction:(SKPaymentTransaction *)transaction {
NSString *receiptStr = [[NSString alloc] initWithData:transaction.transactionReceipt encoding:NSUTF8StringEncoding];
NSDictionary *jsonDictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"algo mas",@"receipt-data",nil];
NSString *jsonString = [jsonDictionary JSONRepresentation];
NSLog(@"string to send: %@",jsonString);
NSLog(@"JSON Created");
urlData = [[NSMutableData data] retain];
//NSURL *sandboxStoreURL = [[NSURL alloc] initWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"https://sandbox.itunes.apple.com/verifyReceipt"]];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];
NSLog(@"will create connection");
[[NSURLConnection alloc] initWithRequest:request delegate:self];
}
maybe I'm forgetting something in the request's headers but I think that the problem is in the method I use to create the JSON object.
HEre's how the JSON object looks like before I add it to the HTTPBody :
string to send: {"receipt-data":"{\n\t\"signature\" = \"AUYMbhY
...........
D0gIjEuMCI7Cn0=\";\n\t\"pod\" = \"100\";\n\t\"signing-status\" = \"0\";\n}"}
The responses I've got:
complete response {
exception = "java.lang.IllegalArgumentException: Property list parsing failed while attempting to read unquoted string. No allowable characters were found. At line number: 1, column: 0.";
status = 21002;
}
Thanks a lot for your guidance.
