• controller层调用

  final List<Article> articleList = [];
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    CAYJHomeRequest.requestArticleList(0).then((value){
      setState(() {
        articleList.addAll(value);
      });
      print(articleList);
    });
  }

使用第三方工具进行模型封装

• json_to_dart:https://javiercbk.github.io/json_to_dart/(数据模型过复杂会丢失代码)

• 使用FlutterJsonBean插件
