写了一个网络请求的工具类，然后想要获取到网络请求的结果，在网络工具类中写了一个接口，暴露除了请求到的数据

代码：

1 package com.lijingbo.knowweather.utils; 2  3 import java.io.ByteArrayOutputStream; 4 import java.io.IOException; 5 import java.io.InputStream; 6 import java.net.HttpURLConnection; 7 import java.net.URL; 8  9 10 public class HttpUtils {11     private static final String TAG = "HttpUtils";12 13     public void getMethod(final String address) {14         new Thread(new Runnable() {15             @Override16             public void run() {17                 HttpURLConnection connection = null;18                 try {19                     URL url = new URL(address);20                     connection = (HttpURLConnection) url.openConnection();21                     connection.setRequestMethod("GET");22                     connection.setConnectTimeout(5000);23                     connection.setReadTimeout(5000);24                     connection.connect();25                     if ( connection.getResponseCode() == 200 ) {26                         InputStream inputStream = connection.getInputStream();27                         ByteArrayOutputStream baos = new ByteArrayOutputStream();28                         byte[] buffers = new byte[1024];29                         int len;30                         while ( (len = inputStream.read(buffers)) != -1 ) {31                             baos.write(buffers, 0, len);32                         }33                         String result = baos.toString();34                         httpCallBack.onSuccess(result);35                         LogUtils.e(TAG, "获取到的服务器信息为：" + result);36                         baos.close();37                         inputStream.close();38 39                     }40                 } catch ( IOException e ) {41                     //网络错误42                     httpCallBack.onError(e.toString());43                     e.printStackTrace();44                 } finally {45                     if ( connection != null ) {46                         connection.disconnect();47                     }48                 }49             }50         }).start();51     }52 53     private HttpCallBack httpCallBack;54     public void setHttpListener(HttpCallBack httpCallBack){55         this.httpCallBack=httpCallBack;56     }57 58     public  interface HttpCallBack {59         void onSuccess(String result);60         void onError(String error);61     }62 }

想要使用该工具类的地方，这样写：

代码：

1         HttpUtils httpUtils=new HttpUtils(); 2         httpUtils.getMethod(url); 3         httpUtils.setHttpListener(new HttpUtils.HttpCallBack() { 4             @Override 5             public void onSuccess(String result) { 6                 LogUtils.e(TAG,"网络请求结果："+result); 7             } 8  9             @Override10             public void onError(String error) {11                 LogUtils.e(TAG,"网络请求结果："+error);12             }13         });
