嘗試使用adal4j獲取令牌

Question

我不知道如何使用adal4j庫獲取沒有用戶名和密碼的令牌。我有這樣的代碼：

public class GetToken implements AuthenticationCallback { 

    public static void main(String[] args) { 
     // TODO Auto-generated method stub 
     String resource = "resource"; 
     String redirectUrl = "redirecturl"; 
     String authority = "https://login.microsoftonline.com/common/"; 
     ExecutorService executor = null; 
     ClientAssertion clientId = new ClientAssertion("my-client-id"); 
     AuthenticationCallback callback; 
     // Authenticate the registered application with Azure Active Directory. 
     AuthenticationContext authContext; 
     try { 
      authContext = new AuthenticationContext(authority, false,executor); 
     } catch (MalformedURLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     Future <AuthenticationResult> result = authContext.acquireToken(resource, clientId, callback); 
    } 

    @Override 
    public void onSuccess(AuthenticationResult result) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onFailure(Throwable exc) { 
     // TODO Auto-generated method stub 

    } 

} 

而且我不知道如何獲得令牌....

Answer 1

，你會得到一個IllegalArgumentException傳遞給AuthenticationContext執行人服務爲空。你能分享拋出的異常嗎？

Answer 2

檢查此鏈接：https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-devquickstarts-webapp-java#step-8-create-the-basicfilter-file-for-basicfilter-mvc

查找到getAccessToke（） method.This是你在找什麼：

ExecutorService executor = Executors.newFixedThreadPool(1); 

希望這有助於！
