2.代码实现

 1 public class MainActivity extends Activity {
 2
 3     @Override
 4     protected void onCreate(Bundle savedInstanceState) {
 5         super.onCreate(savedInstanceState);
 6         setContentView(R.layout.activity_main);
 7     }
 8
 9
10     public void get(View v){
11         EditText et_name = (EditText) findViewById(R.id.et_name);
12         EditText et_pass = (EditText) findViewById(R.id.et_pass);
13
14         final String name = et_name.getText().toString();
15         final String pass = et_pass.getText().toString();
16         String url = "http://192.168.13.13/Web/servlet/CheckLogin?name=" + URLEncoder.encode(name) + "&pass=" + pass;
17         //创建异步httpclient
18         AsyncHttpClient ahc = new AsyncHttpClient();
19
20         //发送get请求提交数据
21         ahc.get(url, new MyResponseHandler());
22     }
23
24     public void post(View v){
25         EditText et_name = (EditText) findViewById(R.id.et_name);
26         EditText et_pass = (EditText) findViewById(R.id.et_pass);
27
28         final String name = et_name.getText().toString();
29         final String pass = et_pass.getText().toString();
30         String url = "http://192.168.13.13/Web/servlet/CheckLogin";
31
32         //创建异步httpclient
33         AsyncHttpClient ahc = new AsyncHttpClient();
34
35         //发送post请求提交数据
36         //把要提交的数据封装至RequestParams对象
37         RequestParams params = new RequestParams();
38         params.add("name", name);
39         params.add("pass", pass);
40         ahc.post(url, params, new MyResponseHandler());
41     }
42
43     class MyResponseHandler extends AsyncHttpResponseHandler{
44
45         //请求服务器成功时，此方法调用
46         @Override
47         public void onSuccess(int statusCode, Header[] headers,
48                 byte[] responseBody) {
49             Toast.makeText(MainActivity.this, new String(responseBody), 0).show();
50
51         }
52
53         //请求失败此方法调用
54         @Override
55         public void onFailure(int statusCode, Header[] headers,
56                 byte[] responseBody, Throwable error) {
57             Toast.makeText(MainActivity.this, "请求失败", 0).show();
58
59         }
60
61     }
