精簡AsyncHttp

AsyncHttp

基於java線程池 實現的 http請求，支持 post和 get、delete等多種請求，實現請求任務和結果異步獲取

,簡化網絡請求

AsyncHttp有哪些功能？

• 基本網絡請求
• 文件下載（支持斷點下載）
  
  • 單線程下載
  • 多線程下載
• 自定義頭部請求信息
• 含有優先級，防止請求無反應
• 文件上傳

使用方法

如何接入？

“`java
compile ‘com.ml.asynchttp:asynchttp-android:1.1.1’

“`

初始化

“`java

    AsyncHttpUtils.init(new RequestInterceptorActionInterface() {
        @Override
        public <T> BaseHttpRequest<T> interceptorAction(BaseHttpRequest<T> baserequest) throws Exception {
            TelephonyManager tm = (TelephonyManager) BaseApplication.getInstance().getSystemService(Context.TELEPHONY_SERVICE);


            return baserequest;
        }
    }, new  ResponseInterceptorActionInterface(){
    );
    LogUtils.setDebug(true);

“`

• 參數1自定義請求處理攔截器，需要實現 RequestInterceptorActionInterface 接口

• 參數2是結果過濾器，可以自定義，只需要 實現 ResponseInterceptorActionInterface 接口

  提示 ： 請求攔截器和過濾器可以在框架初始化添加，也可以在創建請求的時候，添加到請求中

  普通網絡請求

  ##### 常規寫法
    String url=Contents.baseURL+"user/"+ machineid +"/getDutyList.do";
        Log.e("PaiBanActivity",url);
        AsyncHttpUtils.json(url, HttpMethod.Post, new HashMap<String, String>(), new JsonRequestLoadingCallback<PaiBanBean>(this) {
            @Override
            public void requestFail(Exception e, ResponseBody<String> request) {
                e.printStackTrace();
                showToast("網絡出錯,請重試");
            }

            @Override
            public void requsetFinish() {

            }

            @Override
            public void requsetStart() {

            }

            @Override
            public void requestSuccess(PaiBanBean paiBanBean) {
                Log.e("PaiBanActivity",paiBanBean.toString() );
                int status = paiBanBean.getStatus();
                if (status==1) {
                    setPaiBan(paiBanBean);
                }else {
                    showToast("獲取數據失敗,請重試");
                }
            }
        });


        ##### 個性寫法

        ###### 步驟一:定義相關的接口

        public interface PathBeanTest {

        @JSONPOST("http://{ip}.26.106.136:8080/rest/common/user/login.do")
        public CProxyRequester test(@PathParam("ip")String ip, @Param("username")String username, @Param("password")String passwork );


        @GET("http://{ip}.26.106.136:8080/rest/common/allFactorys.do")
        public CProxyRequester getAll(@PathParam("ip")String ip);

        }
        *其中，方法註解包含有：JSONPOST  POST  GET  DELETE  PUT  ....等 ，JSONPOST和POST無技術上差別，只是爲了開發人員辨識清晰
        *方法參數註解，包含兩種，PathParam,Param ,PathParam表示匹配方法註解上的URL佔位符，Param是請求的具體參數 ，注意：
         例如上面的  {ip}  方法中@PathParam("ip")String ip  名稱要對應  否則,請求失敗



    ###### 步驟二:通過代理實例化接口
        PathBeanTest  t=   ProxyCreater.creator(PathBeanTest.class);

    ###### 步驟三:設置結果處理線程級別
        t.getAll("120").ResultMonitor(MIO.MainThread).Observation(new StringRequestResultCallBack<FactoryTestBean>() {
                @Override
                public void requestFail(Exception e, ResponseBody<String> request) {

                }

                @Override
                public void requestSuccess(FactoryTestBean factoryTestBean) {
                    Log.e("tag",factoryTestBean.getMsg()+"  "+factoryTestBean.getData().getList().size());
                }

                @Override
                public void requsetFinish() {

                }

                @Override
                public void requsetStart() {

                }
            });


        ######MIO.MainThread表示主線程，MIO.IOThread  表示IO線程

文件的下載

        寫法一：

        String url="http://scimg.jb51.net/allimg/160815/103-160Q509544OC.jpg";

       //必須設置存儲路徑

        FileRequest resReques=new FileRequest(url);

        resReques.setFilepath(filepath);

        resReques.addHead(new Header("user-agent", "AsyHttp/1.0 ml"));

        resReques.setRequestMethod(HttpMethod.Get);

        TaskHandler taskhandler= AsyncHttp.instance().download(resReques, new FileTest());
        //可以調用 taskhandler.stop()方法取消任務

        //FileTest 是 繼承了 DownProgrossCallback<ResponseBody<T>>的 回掉接口，實現進度的監控，和結果的返回
    }


    寫法二：

多線程下載文件

 多線程下載文件：

        String urls="http://img.taopic.com/uploads/allimg/130711/318756-130G1222R317.jpg";
        String name=urls.substring(urls.lastIndexOf("/")+1,urls.length());
        String filepath="C:\\Users\\admin\\Pictures\\Camera Roll\\"+name;

        download s=  new download(new RecordEntity(urls,filepath));

        s.setTaskPriority(TaskPriority.LOWEST.getValue());//設置優先級


        TaskHandler t=   AsyncHttp.instance().download(s, new DownProgrossCallback<ResponseBody<RandomAccessFile>>() {

        @Override
        public void download_current(long current, long total) {
            // TODO Auto-generated method stub
            // System.out.println("當前 "+e+"  current=="+current+"    total="+total);
        }

        @Override
            public void fail(Exception e1,ResponseBody<RandomAccessFile> response) {

#####一般寫法1

 

   String url=”http://192.168.1.33:8080/StrutsDemo2/upload.action”; 

   UploadRequest resReques=new UploadRequest(url); 

   resReques.addParam(new FileParamPart(“upload”, new File(“C:\Users\admin\Pictures\Camera Roll\img10.jpg”),Constents.TYPE_IMAGE));

resReques.setRequestMethod(HttpMethod.Post);
AsyncHttp.instance().newRequest2(resReques, new uploadTest());
//uploadTest是 繼承了 UploadProgrossCallback
