Androidx学习笔记（38）--- 使用HttpClient框架做GET提交

来源：互联网发布：自动卸载软件脚本编辑：程序博客网时间：2024/05/30 04:19

发送get请求

创建一个客户端对象
HttpClient client = new DefaultHttpClient();
创建一个get请求对象
HttpGet hg = new HttpGet(path);
发送get请求，建立连接，返回响应头对象
HttpResponse hr = hc.execute(hg);

获取状态行对象，获取状态码，如果为200则说明请求成功

if(hr.getStatusLine().getStatusCode() == 200){    //拿到服务器返回的输入流    InputStream is = hr.getEntity().getContent();    String text = Utils.getTextFromStream(is);}

代码

public class MainActivity extends Activity {Handler handler = new Handler(){@Overridepublic void handleMessage(android.os.Message msg) {Toast.makeText(MainActivity.this, (String)msg.obj, 0).show();}};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    public void get(View v){    EditText et_name = (EditText) findViewById(R.id.et_name);    EditText et_pass = (EditText) findViewById(R.id.et_pass);        final String name = et_name.getText().toString();    final String pass = et_pass.getText().toString();            Thread t = new Thread(){    @Override    public void run() {    String path = "http://192.168.13.13/Web/servlet/CheckLogin?name=" + URLEncoder.encode(name) + "&pass=" + pass;        //使用httpClient框架做get方式提交        //1.创建HttpClient对象        HttpClient hc = new DefaultHttpClient();                //2.创建httpGet对象，构造方法的参数就是网址        HttpGet hg = new HttpGet(path);                //3.使用客户端对象，把get请求对象发送出去        try {    HttpResponse hr = hc.execute(hg);    //拿到响应头中的状态行    StatusLine sl = hr.getStatusLine();    if(sl.getStatusCode() == 200){    //拿到响应头的实体    HttpEntity he = hr.getEntity();    //拿到实体中的内容，其实就是服务器返回的输入流    InputStream is = he.getContent();    String text = Utils.getTextFromStream(is);        //发送消息，让主线程刷新ui显示text    Message msg = handler.obtainMessage();    msg.obj = text;    handler.sendMessage(msg);    }    } catch (Exception e) {    // TODO Auto-generated catch block    e.printStackTrace();    }    }    };    t.start();        }}
