I need to invoke an initial GET HTTP request with Basic Authentication. This would be the first time the request is sent to the server and I already have the username & password so there’s no need for a challenge from the server for authorization.

First question:

  1. Does NSURLConnection have to be set as synchronous to do Basic Auth? According to the answer on this post, it seems that you can’t do Basic Auth if you opt for the async route.

  2. Anyone know of any some sample code that illustrates Basic Auth on a GET request without the need for a challenge response? Apple’s documentation shows an example but only after the server has issued the challenge request to the client.

I’m kind of new the networking portion of the SDK and I’m not sure which of the other classes I should use to get this working. (I see the NSURLCredential class but it seems that it is used only with NSURLAuthenticationChallenge after the client has requested for an authorized resource from the server).

    I’m using an asynchronous connection with MGTwitterEngine and it sets the authorization in the NSMutableURLRequest (theRequest) like so:

    NSString *authStr = [NSString stringWithFormat:@"%@:%@", [self username], [self password]];
NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding];
NSString *authValue = [NSString stringWithFormat:@"Basic %@", [authData base64EncodingWithLineLength:80]];
[theRequest setValue:authValue forHTTPHeaderField:@"Authorization"];

    I don’t believe this method requires going through the challenge loop but I could be wrong
