401 유니버설 앱에서 트위터에 상태를 게시하는 동안 Unauthorized (WebException)

Question

트위터에 로그인 할 기능을 제공하고 싶습니다. &으로 게시하십시오. Windows 8.1 Universal app에서 트윗을 게시하십시오. 타사 라이브러리로 이동하라고 제안하지 마십시오. 나는 단지 두 가지 일을하고 싶다. 내 노력은 아래와 같습니다. 나는 나의 인증이 틀렸다는 것을 의심한다. 나는 얻고있다 System.Net.WebException => 원격 서버가 오류를 반환했습니다 : (401) Unauthorized. 내 코드가 잘못된 이유는 무엇입니까?

당신이 당신의 콜백 URL http://f.com 찾을 않았다 있었습니까?

, 나는 그런

var oWebBroker = Windows.Security.Authentification.Web.WebAuthenticationBroker; 
var endURI = oWebBroker.getCurrentApplicationCallbackUri().absoluteUri; 

... 

oWebBroker.authenticateAndContinue(startURI, endURI); 

같은 것을 사용하고 포 스퀘어에 연결하려면 제공되는 endURI이 MS-응용 프로그램 같은 것입니다 : // S-1-15-2-26 ... 33520119519/
