发送post请求

使用RequestParams对象封装要携带的数据

//创建异步httpclient对象AsyncHttpClient ahc = new AsyncHttpClient();//创建RequestParams封装要携带的数据RequestParams rp = new RequestParams();rp.add("name", name);rp.add("pass", pass);//发送post请求ahc.post(path, rp, new MyHandler());

案例代码

public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }     public void post(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();    String url = "http://192.168.13.13/Web/servlet/CheckLogin";        //创建异步httpclient    AsyncHttpClient ahc = new AsyncHttpClient();        //发送post请求提交数据    //把要提交的数据封装至RequestParams对象    RequestParams params = new RequestParams();    params.add("name", name);    params.add("pass", pass);    ahc.post(url, params, new MyResponseHandler());    }  //响应处理器  class MyResponseHandler extends AsyncHttpResponseHandler{    //请求服务器成功时，此方法调用@Overridepublic void onSuccess(int statusCode, Header[] headers,byte[] responseBody) {Toast.makeText(MainActivity.this, new String(responseBody), 0).show();}//请求失败此方法调用@Overridepublic void onFailure(int statusCode, Header[] headers,byte[] responseBody, Throwable error) {Toast.makeText(MainActivity.this, "请求失败", 0).show();}        }    }
