Reading jSON object request via key-value pair
Question
I am trying to read jSON response in form of key value pair.
When I am manually hitting the URL via browser I am getting the required status code/response via jSON object
{"status":"0","responseCode":"1021","response":{"message":"Please check your Settings ","data":"2012-11-24, 7:28 am"}}
The same expected response is not obtained when I am trying to do it via my app.My code when I am sending data via app
[dictionnary setObject:@"admin" forKey:@"username"];
[dictionnary setObject:@"123123" forKey:@"password"];
NSError *error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary
options:kNilOptions
error:&error];
NSString *urlString = @"MY CALL URL";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:jsonData];
NSURLResponse *response = NULL;
NSError *requestError = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError];
NSLog(@"response is obtained");
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ;
NSLog(@"%@", responseString);
Response I am getting via code

specify in your URLRequest that you dont want html but you want raw json
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
to:
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];//!!!

You can try the following code May be help you.
NSString *username = emailField.text;
NSString *password = passwordField.text;
NSMutableDictionary *dictionnary = [NSMutableDictionary dictionary];
[dictionnary setObject:@"admin" forKey:@"username"];
[dictionnary setObject:@"123456" forKey:@"password"];
NSError *error = nil;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary
options:kNilOptions
error:&error];
NSString *urlString = @"Sample URL";
NSURL *url = [NSURL URLWithString:urlString];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setHTTPBody:jsonData];
NSURLResponse *response = NULL;
NSError *requestError = NULL;
NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ;
NSLog(@"%@", responseString);
if it is a GET Request then, can you try link : /index.php/api/transaction/model/transactionsuccess?username=admin&password=12123
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"/index.php/api/transaction/model/transactionsuccess?username=admin&password=12123"]];
// Perform request and get JSON as a NSData object
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSLog(@"response=%@",response );
and use this code.

This problem is related to server side; so you must consult to back-end developer of the service and more possibly, check at service side the data hit using POST or GET, and if back-end is of php, so for a moment advised him to use $request instead of $get or $post, just to test. Also, this fact is obvious as you mentioned that as you tried the url from browser you get the required json, but in the case of POST you never able to do that.
I'm 100% sure this is from server side.If possible provide me the required server url with test auth variables. (cross-check your full url with the params as you provide either via break points or via log.)
