Got Forbidden instead of json data

I just need these recent blog posts!

Here is my NSURL Code:

NSURLSession *session = [NSURLSession sharedSession];
NSURL *url = [[NSURL alloc] initWithString:@"http://blog.teamtreehouse.com/api/get_recent_summary/"];
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
NSURLSessionDownloadTask *task = [session downloadTaskWithRequest:request completionHandler:^(NSURL *location, NSURLResponse *response, NSError *error) {
        NSString *text = [[NSString alloc] initWithContentsOfURL:location encoding:NSUTF8StringEncoding error:nil];
        NSLog(@"Response: %@", text);
    }];
    [task resume];
}

Hi Alexander,

I don't actually know a whole lot of Objective-C, but I can see you have one opening curly brace and two closing braces. That's likely where your problem comes from.

Let us know if that solves it.

OK, looking at the video, I'm guessing that extra closing curly brace is actually closing viewDidLoad(), so that's not your problem.

Your code seems to match the video. If you copy and paste the url http://blog.teamtreehouse.com/api/get_recent_summary/ into your browser (or just click this link), do you see JSON data?

Yes, I do. I've no idea where the problem is. I tried to access the JSON Data with the teachers project and it had worked. After that I pasted the whole viewDidLoad method in my code hoping it'll work but it doesn't. So there is no issue with my viewDidLoad method i guess.

Do you get the error that states you can not make a connection over HTTP? This error to be exact ----> App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure

@ Pablo, that's the error that I got - my response was Null.

I had found the same in one of the earlier courses too.

That link contains a solution.

I believe that the default setting was changed, which is why you need to do this step.

Sorry, some random markup on the end.

If you remove the characters after transport it will work.
