我遇到了由Chris Kacerguis维护的流行的REST API codeigniter的问题，我创建了一个Datadiri控制器，如下所示：

<?php
require (APPPATH.'/libraries/REST_Controller.php');

class Datadiri extends REST_Controller{
    function __construct($config = 'rest'){
        parent::__construct($config);
    }
    //tampilkan data
    function index(){
        $buku = $this->db->get('perpustakaan');
        $this->response($buku, 200);
    }
}

这是Rest_controller.php https://github.com/chriskacerguis/codeigniter-restserver/blob/master/application/libraries/REST_Controller.php

但是还是一样，找不到错误类“ REST_Controller”。我该如何解决？

致命错误：在第4行的C：\ xampp \ htdocs \ CodeIgniter \ application \ controllers \ datadiri.php中找不到类“ REST_Controller”

严重性：错误

消息：找不到类“ REST_Controller”

文件名：controllers / datadiri.php

行号：4

我如何从片段中清除共享偏好？谢谢

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
       sharedPreferences = getActivity().getSharedPreferences("login.conf", Context.MODE_PRIVATE);

        editor = sharedPreferences.edit();
        editor.clear();
        editor.commit();
        Intent logout = new Intent(getActivity(), LoginActivity.class);
        startActivity(logout);
        Log.d(TAG, sharedPreferences.getString("username", ""));
        Log.d(TAG, sharedPreferences.getString("password", ""));
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_fragment_logout, container, false);
    }

那是我的片段
