上一篇文章我们讲到 amis如何让用户自由更改的方法，不通过起前端同学重新更改代码打包部署的操作。https://blog.csdn.net/Alan0728/article/details/119213559?spm=1001.2014.3001.5502

这篇文章我们看一下amis如何生成JSON

首先打开amis 可视化编辑器, 在线体验：http://aisuda.github.io/amis-editor-demo

 点击进去后

 左侧是组件 通过托拉拽到中间内容部分，完成一个布局上的操作。右侧是一些常规性的配置，接口字段样式等等的一些配置。当配置完成后点击左侧组件下的<代码> 生成的是JSON格式。

 结合上一篇文章，直接复制生成的JSON，通过接口保存到数据库，完成整个页面的渲染。这种操作对用户来说是一个零代码的开发。

下面是我拉的一个简单的后台管理系统的集合，有兴趣的话可以体验一下
