Json web service https

Question

Could you help me, with a example, where i consume a json webservice in a https url. i have tried: where urlConParametros is a https url.

NSString* encriptado = nil;
NSString* urlConParametros = [NSString stringWithFormat:@"%@%@?%@=%@", URL, metodo, key, valorSinEcncriptar];
NSError* error;
if(encriptado == nil){
    NSMutableURLRequest *getRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlConParametros]];
    [getRequest setHTTPMethod:@"GET"];
    NSError *requestError;
    NSURLResponse *urlResponse = nil;
    NSData *response1 =[NSURLConnection sendSynchronousRequest:getRequest returningResponse:&urlResponse error:&requestError];
    NSString* data = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlConParametros] encoding:NSUTF8StringEncoding
                                           error:&error];
    return data;
}

but return data nil. My problem is that with http, the same web service response the correct data, but when it doing with https, the response is nil.

My first guess would be parameter encoding. Is there a simpler endpoint in the web service that doesn't take parameters? Start with that and see if you can make a simple get work. Then look at this http://stackoverflow.com/questions/8088473/url-encode-an-nsstring. Also, consider changing to asynchronous once you get this working. — danh, Jul 16 '13 at 15:34

Please add some more details in the Question about What you want exactly, What you have tried and What are the Problems you are facing while implementation ?

If you want to GET some data from the Web Service , you can get it like this. :

NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlConParametros]];
NSString *respStr = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
NSLog(@"My Response :: %@",respStr);

If the Response is in JSON Format then you should do something like this :

NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:urlConParametros]];
NSError* error;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(@"My Response :: %@",json);

Take a look at the Sample Code for AdvancedURLConnections.
