AsyncHttpClient的使用

不要做代碼的輪子

與其重復的寫代碼，不如利用別人寫好的代碼開發時更節省時間，最近從github上下載了一套代碼，http異步請求get,post請求，也可以用作文件上傳，很方便，感覺比較好，推薦給大家用

以登錄為例，代碼寫的可能不太好，試著應用一下

    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(),  
                                            "網絡連接超時", 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.根據需要調用client中get,post請求

3，重寫onSuccess（）和onFailure（）方法

注：在https://github.com/AsyncHttpClient/async-http-client下載包，直接將library下的包直接粘貼到項目src下，直接調用即可
