iphone - how to make JSON data for NSMutableURLRequest GET Method

I'm using JSONKit.h, JSONKit.m, ios5.1.

and I tried to send data using GET method and POST also but my django server gave errors.

Is my code wrong?

here is my codes.

NSString *myid = @"myidddd";
NSString *mypw = @"mypwwww";
NSArray *objects = [NSArray arrayWithObjects:myid,mypw, nil];
NSArray *keys = [NSArray arrayWithObjects:@"id", @"pw", nil];
NSDictionary *dic = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

NSString *jsonInfo = [dic JSONString];
NSData *jsonData = [jsonInfo dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:[[NSURL alloc] initWithString:@"http://www.scg.com:8000/post"]];
[request setHTTPMethod:@"GET"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:[NSString stringWithFormat:@"%d", [jsonData length]] forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:jsonData];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *res, NSData *data, NSError *err){
    [self didReceiveData:data];
}];

Errors when my django server received the data,

Self answer.

The GET method can't contain data into http body. It is possible only use POST method.

To send some information with GET method, use extended request URL like:

"?%@=%@", key, value

Here is sample URL:

http://www.somedomain.com/?name=username&pw=password
