AsyncHttpClient的使用

不要做代码的轮子

与其重复的写代码，不如利用别人写好的代码开发时更节省时间，最近从github上下载了一套代码，http异步请求get,post请求，也可以用作文件上传，很方便，感觉比较好，推荐给大家用

以登录为例，代码写的可能不太好，试着应用一下

AsyncHttpClient client = new AsyncHttpClient();

					RequestParams params = new RequestParams();

					params.add("RequestType", "");
					params.add("UserID", "-1");
					params.add("NurseID", "-1");
					params.add("HospitalId", "-1");

					JSONObject jsonObject = new JSONObject();
					try {
						jsonObject.put("UserCode", username);
						jsonObject.put("Password", password);
					} catch (JSONException e) {
						// TODO Auto-generated catch block
						e.printStackTrace();
					}

					params.add("RequestParam", jsonObject.toString());

					client.get(path, params, new TextHttpResponseHandler() {

						@Override
						public void onSuccess(int statusCode, Header[] headers,
								String responseString) {
							// TODO Auto-generated method stub
							if (statusCode == 200) {

								// Toast.makeText(getApplicationContext(),
								// responseString, Toast.LENGTH_SHORT)
								// .show();
											Intent intent = new Intent();
											intent.setClass(
													getApplicationContext(),
													MainActivity.class);
											startActivity(intent);
										} else {
											Intent intent = new Intent();
											intent.setClass(
													getApplicationContext(),
													MainActivity.class);
											startActivity(intent);
										}

									} else {
										Toast.makeText(getApplicationContext(),
												msg, Toast.LENGTH_SHORT).show();
									}
								} catch (JSONException e) {
									// TODO Auto-generated catch block
									e.printStackTrace();
								}
							}else {
								Toast.makeText(getApplicationContext(),
										"网络连接超时", Toast.LENGTH_SHORT).show();
							}
						}

						@Override
						public void onFailure(int statusCode, Header[] headers,
								String responseString, Throwable throwable) {
							// TODO Auto-generated method stub
							Toast.makeText(getApplicationContext(),
									responseString, Toast.LENGTH_SHORT).show();
						}

1.声明一个client对象，初始化

2.根据需要调用client中get,post请求

3，重写onSuccess（）和onFailure（）方法

注：在https://github.com/AsyncHttpClient/async-http-client下载包，直接将library下的包直接粘贴到项目src下，直接调用即可
