    今天尝试将获取数据封装为一个类:

    package com.example.bowenwang;
    
    import android.os.Message;
    import android.util.Log;
    
    import org.json.JSONArray;
    import org.json.JSONException;
    import org.json.JSONObject;
    
    import java.io.IOException;
    import java.util.ArrayList;
    import java.util.List;
    
    import okhttp3.FormBody;
    import okhttp3.OkHttpClient;
    import okhttp3.Request;
    import okhttp3.RequestBody;
    import okhttp3.Response;
    
    public class getdata {
        List<Bean> list=new ArrayList<>();
        private OkHttpClient okHttpClient=new OkHttpClient();
        public List<Bean> get(int classify){
                    new Thread(){
                @Override
                public void run() {
                    super.run();
                    list=new ArrayList<>();
                    String url="http://39.103.196.146:8888/getNewsData/GetNewsDataServlet";
                    try {
                        String result=getData(url,classify);
                        manageResponse(result);
                    } catch (IOException | JSONException e) {
                        e.printStackTrace();
                    }
                }
            }.start();
            return list;
        }
        private String getData(String url,int classify) throws IOException {
            RequestBody responseBody=new FormBody.Builder()
                    .add("classify", String.valueOf(classify+1))
                    .build();
            Request request=new Request.Builder().post(responseBody).url(url).build();
            Response response=okHttpClient.newCall(request).execute();
            return response.body().string();
        }
        private void manageResponse(String result) throws JSONException {
            JSONArray jsonArray=new JSONArray(result);
            for(int i=0;i<jsonArray.length();i++)
            {
                JSONObject jsonObject=jsonArray.getJSONObject(i);
                String title=jsonObject.getString("title");
                String time=jsonObject.getString("time");
                String place=jsonObject.getString("place");
                String author=jsonObject.getString("author");
                String content=jsonObject.getString("content");
                String img=jsonObject.getString("img");
                Bean bean=new Bean();
                bean.setTitle(title);
                bean.setTime(time);
                bean.setPlace(place);
                bean.setContent(content);
                bean.setImg(img);
                list.add(bean);
            }
        }
    }
