// golang
type SomeHandler struct{}

func (*SomeHandler) ServeHTTP(w http.ResponseWriter, req *http.Request) {

    content, err := ioutil.ReadAll(req.Body)
    if err != nil {
        // do sth.
        return
    }

    // decode JSON
    // ...
}

// Objective-C on iOS 6/7
// NSURL *myUrl = ...
NSMutableURLRequest *req = [[NSMutableURLRequest alloc] initWithURL:myUrl];
[req setHTTPMethod:@"POST"];
[req setValue:@"application/json; charset=utf-8" forHTTPHeaderField:@"Content-Type"];

id obj = @{
             @"username" : @"myname",
             @"password" : @"mypwd",
          };
NSError *error; …
