项目实战：一、json解析数据的框架

这是json解析数据的工具类 到时候直接调用这个工具类 进行解析数据

 

import android.graphics.Bitmap;

import android.graphics.BitmapFactory;

import android.util.Log;

 

import java.io.BufferedReader;

import java.io.IOException;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.net.HttpURLConnection;

import java.net.MalformedURLException;

import java.net.URL;

 

/**

        * guo

        */

public class NetWorkUtils {

 

    /**

     * 请求网络图片

     *

     * @param mUrl 接口地址

     * @return bitmap

     */

    public static Bitmap getBitmpa(String mUrl) {

        try {

 

            URL url = new URL(mUrl);//封装url接口

            //打开了连接

            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

            int responseCode = urlConnection.getResponseCode();

            if (responseCode == 200) {

                InputStream inputStream = urlConnection.getInputStream();

                Bitmap bitmap = BitmapFactory.decodeStream(inputStream);

                return bitmap;

            } else {

                Log.e("wzq", "responseCode---bitmap:" + responseCode);

            }

        } catch (MalformedURLException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

        return null;

    }

 

    public static String getJson(String urlString) {

        try {

 

            URL url = new URL(urlString);//封装url接口

            //打开了连接

            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

            int responseCode = urlConnection.getResponseCode();

            if (responseCode == 200) {

                InputStream inputStream = urlConnection.getInputStream();

                BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));

                String temp="";

                StringBuilder stringBuilder = new StringBuilder();

                while ((temp  =bufferedReader.readLine()) != null){

                    stringBuilder.append(temp);

 

                }

                return  stringBuilder.toString();

 

 

            } else {

                Log.e("wzq", "responseCode---json:" + responseCode);

            }

        } catch (MalformedURLException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

 

 

        return "";

 

    }

}
