okhttp封装
Okhttp 是一个 android 网络请求框架，如果不进行封装 调用会超麻烦，就会有大量的重复代码。
思路：分别封装 get，post，put，delete 请求，设置 interface 完成与失败 的 方法供外部自己实现
经过封装好OkhttpHelper的就可以下面这样调用, 只需要写成功与失败的逻辑了。
OkhttpHelper okhttpHelper = new OkhttpHelper();
Map<String, String> map = new HashMap<String, String>();
map.put("test", "fuck");
map.put("af", "你好");
okhttpHelper.get("dynamic", map, new OkhttpHelper.listener() {
@Override
public void onSuccess(String response) {
Log.e("this", response);
}
@Override
public void onError() {
}
});下面是OkhttpHelper 复制粘贴吧，
提醒：记得改下面类属性host 你自己的主机
