AsyncHttpClient使用示例代码，asynchttpclient,实现http异步请求ge

实现http异步请求get,post请求，也可以用作文件上传。下面是登录的示例```java 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
