使用Java中的用户名和密码的Microsoft Graph Access Token

Question

我可以使用java中的电子邮件和密码获取访问令牌吗？我看到很多使用.NET库的例子，但没有任何关于java的例子，我尝试了以下内容： -

private static String getAccess_Token() {
       AuthenticationContext authContext = null;
        AuthenticationResult authResult = null;
        ExecutorService service = null;

        try {
            service = Executors.newFixedThreadPool(1);
            String url = "https://login.microsoftonline.com/" + Authentication_Constants.TENANT + "/oauth2/authorize";
            authContext = new AuthenticationContext(url, false, service);
            Future<AuthenticationResult> future = authContext.acquireToken(Authentication_Constants.RESOURCE, Authentication_Constants.CLIENTID, 
                    Authentication_Constants.EMAIL, Authentication_Constants.Passowrd, null);

            authResult = future.get();
           /* System.out.println("get access token: \n" + authResult.getAccessToken());
            System.out.println("get refresh token: \n" + authResult.getRefreshToken());*/
            return authResult.getAccessToken();
        } catch (Exception ex) {
            ex.printStackTrace();
        }
    return null;
}

但它给我一个例外

 com.microsoft.aad.adal4j.AuthenticationException: {"error_description":"AADSTS70002: The request body must contain the following parameter: 'client_secret or client_assertion'.

是否有其他API可以让我这样做？
