I am in a situation where I need to send authentication (basic HTTP Authentication)

  • 0

I am in a situation where I need to send authentication (basic HTTP Authentication) to a server but the server does not send me a challenge first. This has been tracked down to be a duplicate of the wget switch –auth-no-challenge. My problem is, I do not see any way to get NSURL to do this.

I have implemented basic authentication in my NSURLConnection delegate but the -connection: didReceiveAuthenticationChallenge: method is not getting called.

Is there any way to force this call or to embed the authentication information for this strange situation?

    You can add the authorization information to the request manually by adding it to the request header like so:

    NSString *authString = [[[NSString stringWithFormat:@"%@:%@",user, password] dataUsingEncoding:NSUTF8StringEncoding] base64Encoding];        
[request setValue:[NSString stringWithFormat:@"Basic %@", authString] forHTTPHeaderField:@"Authorization"];

    Where request is your NSMutableURLRequest and user/password are your respective username and password NSString’s

    I’ve been using this approach with an API from the iphone where the extra challenge is not being initiated by the server.
