POiOS - How to attach a JSON Object to web request? (NOT using NSURLConnection)
text
Body
copied!<p>I am trying to send some web requests to back-end API I have setup on my web server. However, to make things universal I would like to send an entire JSON object to the back-end, and do all my filtering of data there to determine what the request is for, what arguments to pass, etc.</p> <p>I will be making many requests from one class to different services, so I don't want to use NSURLConnection as it gets messy having to filter through all the results in the completion handler to determine which request was originally being fetched.</p> <p>I like how NSURLConnection allows you to attach a JSON object like this, but I want to know how to do it with a different method (say [NSData dataWithContentsOfURL:])</p> <pre><code>NSMutableDictionary *postObject = [[NSMutableDictionary alloc] init]; [postObject setValue:@"login" forKey:@"request"]; [postObject setValue:inputUsername.text forKey:@"userName"]; [postObject setValue:inputPassword.text forKey:@"password"]; NSData *postData = [NSJSONSerialization dataWithJSONObject:postObject options:0 error:NULL]; NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init]; [request setURL:[NSURL URLWithString:@"WEB_URL"]]; [request setHTTPMethod:@"POST"]; [request setValue:postLength forHTTPHeaderField:@"Content-Length"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [request setHTTPBody:postData]; [request setTimeoutInterval:20]; </code></pre> <p>Any suggestions?</p>
