NSURLConnection Authorization Header not Working

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:

  • Getting data out of the NSURLResponse completion block
  • Determining Trust With NSURLConnection and NSURLProtectionSpace
  • iOS background Location not sending http request
  • Asynchronous NSURLConnection Throws EXC_BAD_ACCESS
  • NSURLRequest Timeout IOS
  • UIWebView Delegate get MIME Type
  • NSURL *aUrl = [NSURL URLWithString: @"http://generericfakeapi.com/user/profile"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:aUrl
    [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.

    Change this line:

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


    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
