1.get方法的封装AsyncTask

public class DBUTil2 {
    public static interface Succee{
        void onSuccee(String result);
    }
    public static interface Fail{
        void onFail();
    }

　public static void getDataByGetInterface(final Map map, final Succee successCallback,
                                         final Fail failCallback){
    new AsyncTask<Void,Void,String>(){

        @Override

        protected void onPostExecute(String s) {
            super.onPostExecute(s);
            if(s!=null){
                if(successCallback!=null){
                    successCallback.onSuccee(s);
                }
            }else{
                if(failCallback!=null){
                    failCallback.onFail();
                }
            }
        }
        @Override
        protected String doInBackground(Void... voids) {
            String s = null;
            try {
                URL url = new URL((String) map.get("url"));
                HttpURLConnection conn= (HttpURLConnection) url.openConnection();
                conn.setRequestMethod("GET");
                if(conn.getResponseCode()==200){
                    InputStream in=conn.getInputStream();
                    BufferedReader bufferedReader=new BufferedReader(new InputStreamReader(in));
                    s= bufferedReader.readLine();
                }
            } catch (MalformedURLException e) {
                e.printStackTrace();
            } catch (ProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return s;
        }
    }.execute();
}
}

2.post方法的封装方法

public class DBUTil2 {
    public static interface Succee{
        void onSuccee(String result);
    }
    public static interface Fail{
        void onFail();
    }
    public static void post(final Map map,final Succee succee ,final Fail fail ){
        new AsyncTask<Void,Void,String>(){
            @Override
            protected void onPostExecute(String s) {
                if (s!=null){
                    if (succee!=null){
                        succee.onSuccee(s);
                    }else {
                        if (fail!=null){
                            fail.onFail();
                        }
                    }
                }
                super.onPostExecute(s);
            }

            @Override
            protected String doInBackground(Void... voids) {
                String s = null;
                String json = null;
                OutputStream outputStream = null;
                InputStream inputStream = null;
                BufferedReader bufferedReader = null;
                try {
                    URL url = new URL((String) map.get("url"));
                    HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                    connection.setRequestMethod("POST");
                    connection.setConnectTimeout(5000);
                    connection.setReadTimeout(5000);
                    connection.setUseCaches(false);
                    connection.setDoOutput(true);
                    outputStream = connection.getOutputStream();
                    JSONObject jsonObject = new JSONObject("jsonobject");
                    outputStream.write(jsonObject.toString().getBytes());
                    if (connection.getResponseCode()==200){
                        inputStream = connection.getInputStream();
                        bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
                        while ((s=bufferedReader.readLine())!=null){
                            json+=s;
                        }
                        inputStream.close();
                        bufferedReader.close();
                        outputStream.flush();
                        outputStream.close();
                    }
                } catch (MalformedURLException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                } catch (JSONException e) {
                    e.printStackTrace();
                }
                return json.substring(4,json.length());
            }
        }.execute();
    }
