I have a link which contains the a json file. I mean if I launch that link in chrome a file is downloaded on my computer which is of .json extension.
say the link is `www.foffa.com/sampleList.json`
I am new to AFNetworking and not sure how to parse this json, with or without having to write this file down to the disk.

My code looks like below and I am pretty sure that I have to use streams and all for this but I am not sure how. As of now I get an error `"Request failed: unacceptable content-type: text/plain"`
I guess it expects the content type to be `"Content-Type" = "application/octet-stream";`

```
    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
    operation.responseSerializer = [AFHTTPResponseSerializer serializer];
    operation.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"application/octet-stream"];
    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
             NSLog(@"Data retrived");       
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Weather"
                                                            message:[error localizedDescription]
                                                           delegate:nil
                                                  cancelButtonTitle:@"Ok"
                                                  otherButtonTitles:nil];
        [alertView show];
    }];

```
