NSURLConnection Authorization Header not Working

Question

I am trying to send an OAuth access token in an HTTP header via NSURLConnection but it doesn't seem to be sending the header because the API keeps giving me an error saying that "must provide authorization token".

This is the code that I am using:

NSURL *aUrl = [NSURL URLWithString: @"http://generericfakeapi.com/user/profile"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
                                                       cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                   timeoutInterval:30.0];

[request addValue:[NSString stringWithFormat:@"OAuth %@", token] forHTTPHeaderField:@"Authorization"];

[request setHTTPMethod:@"GET"];

NSError *error = nil;
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error: &error];

NSDictionary *JSONDictionary = [NSJSONSerialization JSONObjectWithData:returnData options:kNilOptions error:&error];
NSLog(@"Response : %@", JSONDictionary);

And this is an example of the cURL command for the API:

curl 'http://generericfakeapi.com/user/profile' -H 'Authorization: OAuth YourAuthToken'

Is this not what I am essentially doing through NSURLConnection?

Any help would be appreciated.

Answer 1

Change this line:

NSURL *aUrl = [NSURL URLWithString: @"http://generericfakeapi.com/user/profile"];

To:

NSURL *aUrl = [NSURL URLWithString: @"http://generericfakeapi.com/user/profile/"];

Apparently iOS drops the Authorization header if there isn't a slash at the end of a URL. This problem literally cost me my sleep for two days.

For me it look fine. Are you sure you gave a valid token? Try catch the error like this

if (error) {
    NSLog(@"error : %@", error.description);
}

My code work well :

NSURL *jsonURL = [NSURL URLWithString:[NSString stringWithFormat:@"http://....ID=%i", cellID]];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:jsonURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:120.0];
[request setValue:@"Basic ...." forHTTPHeaderField:@"Authorization"];
NSURLResponse *response;
NSError * error  = nil;
NSData *POSTReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

hope it helps
