Question

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,

Answer 1

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
