Javascript JSURL在android中不起作用

您好，在我的应用程序中，我使用这个js文件来获取json响应

xamp->htdoc->node chat->node_modules->config->request

这是文件的路径

在客户端，我使用这样的路径

UserFragment.java

public class UserFragment extends Fragment {
ListView list;
ArrayList<HashMap<String, String>> users = new ArrayList<HashMap<String, String>>();
Button refresh,logout;
List<NameValuePair> params;
SharedPreferences prefs;


@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
    View view =inflater.inflate(R.layout.user_fragment, container, false);
    prefs = getActivity().getSharedPreferences("Chat", 0);

    list = (ListView)view.findViewById(R.id.listView);
    refresh = (Button)view.findViewById(R.id.refresh);
    logout = (Button)view.findViewById(R.id.logout);
    logout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            new  Logout().execute();

        }
    });
    refresh.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            getFragmentManager().beginTransaction().remove(getFragmentManager().findFragmentById(R.id.content_frame)).commit();
            Fragment reg = new UserFragment();
            FragmentTransaction ft = getFragmentManager().beginTransaction();
            ft.replace(R.id.content_frame, reg);
            ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
            ft.addToBackStack(null);
            ft.commit();

        }
    });
    new Load().execute();

    return view;

对于（var i=0；我能告诉你在哪里定义/注销路由吗？我看不到。对不起，刚才我编辑了我的帖子。好吧，我知道了，这是一个不同的路由。但现在的问题是，我仍然看不到你在哪里定义哪个函数处理对该路由的调用？这只是我在问如何给出路由我认为你应该考虑像Connect这样的东西或者Express.js。
