用xutils3.0来访问 spring boot，带权限验证

public static void postNewServer() {
RequestParams params = new RequestParams("http://172.16.1.215:8080/api/i/users/list");
byte[] bytes = String.format("%s:%s", "abc", "2505").getBytes();
String aut = String.format("Basic %s", Base64Utils.encodeToString(bytes));
//        byte[] encodedPassword = (userName + ":" + password).getBytes();
//        BASE64Encoder encoder = new BASE64Encoder();
params.addHeader("Authorization", aut);
x.http().get(params, new Callback.CacheCallback<String>() {

@Override
public void onSuccess(String result) {

Log.d("dd", "suc");

DbCookieStore instance = DbCookieStore.INSTANCE;
List<HttpCookie> cookies = instance.getCookies();
for (HttpCookie heCo : cookies

Log.d("dd", heCo.getName() + heCo.getValue());
}
}

@Override
