本文介绍如何对Android的HttpUrlConnection进行轻量级封装，类似xutils3的用法，提供简单易用的网络通信接口。

使用方法：

        Map<String,String> map=new HashMap<String,String>();
        map.put("flag","getpost");
        SuperHttpUtil.get(map,"http://101.201.239.73:8080/FSwimRing/FSwimRing", new SuperHttpUtil.HttpCallBack() {
            @Override
            public void onSuccess(String result) {
                Toast.makeText(MainActivity.this,"onSuccess",Toast.LENGTH_SHORT).show();
                Log.e("wccc",result);
            }
            
            @Override
            public void onError(Exception e) {
                Toast.makeText(MainActivity.this,"onError",Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onFinish() {
                Toast.makeText(MainActivity.this,"onFinish",Toast.LENGTH_SHORT).show();
            }
        });
