android网络编程——http get

博客源址：android网络编程——http get

     在Android SDK中提供了Apache HttpClient(org.apache.http.*)模块。在这个模块中涉及到两个重要的类：HttpGet和HttpPost。这一篇一个实例给出httpGet的使用方法：

首先在Manifest中加权限：

<uses-permission android:name="android.permission.INTERNET"/>

代码如下（实际应用时另起线程）：

 public class HttpGetDemo extends Activity {
     /** Called when the activity is first created. */
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         BufferedReader in = null;
         try {
             HttpClient client = new DefaultHttpClient();
             HttpGet request = new HttpGet("http://www.baidu.com");
             HttpResponse response = client.execute(request);
             in = new BufferedReader(
                     new InputStreamReader(
                         response.getEntity().getContent()));

             StringBuffer sb = new StringBuffer("");
             String line = "";
             String NL = System.getProperty("line.separator");
             while ((line = in.readLine()) != null) {
                 sb.append(line + NL);
             }
             in.close();

             String page = sb.toString();
             System.out.println(page);
         } catch (Exception e) {
             // TODO Auto-generated catch block
             e.printStackTrace();
         } finally {
             if (in != null) {
                 try {
                     in.close();
                 } catch (IOException e) {
                     e.printStackTrace();
                 }
             }
         }
     }
 }
