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();                                }  

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
