HttpClient的简单使用

public class MainActivity extends AppCompatActivity {

public String urlString = "http://api.expoon.com/AppNews/getNewsList/type/1/p/1";

 @Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    
    setContentView(R.layout.activity_main);
    
    new Thread(){
    
        @Override
        
        public void run() {
        
            super.run();
            
            //联网工具类，DefaultHttpClient封装了请求操作
            
            DefaultHttpClient defaultHttpClient = new DefaultHttpClient();
            
            //初始化请求方式，并把接口传入；
            
            HttpGet httpGet = new HttpGet(urlString);
            
//     HttpPost httpPost = new HttpPost(urlString);

            try {
            
                //执行httpGet操作；
                
                HttpResponse response = defaultHttpClient.execute(httpGet);
                
                int statusCode = response.getStatusLine().getStatusCode();
                
         		Log.e("wzq","statusCode::" +statusCode);
 	 // String sss = URLEncoder.encode("sss");

                if (statusCode == 200){
                
                    //entity包含服务器返回的数据
                    
                    HttpEntity entity = response.getEntity();
                    
                    //EntityUtils是专门处理操作entity中的数据的一个类；
                    
                    String jsonResult =  EntityUtils.toString(entity);
                    
                    Log.e("wzq",jsonResult);
                    
                }else {
                
                    //do nothing
                }
                
            } catch (IOException e) {
                e.printStackTrace();
                Log.e("wzq","e:" +e.toString());
               String urlString = 	"http://api.expoon.com/AppNews/getNewsList/type/1/p/1";

            }
        }
