convert json to go struct(one nest struct and multi normal separate structs),you can check my another project https://github.com/GrayOxygen/json-go-struct-app/ just a app version of this project
- 将json转为golang的struct,目前开源的项目、工具中,只找到转成嵌套的struct形式,于是写了个转成非嵌套的struct
- 思路:用已有库生成内嵌struct,再构建树,从顶部到底部依次入栈(左大括号)出栈(右大括号)即得到树模型,只需注意每层是否有struct或者struct数组的类型的儿子节点(不看孙子及以下节点),替换为*某struct和[]*某struct这种形式即可,我的替换方式是,对于某层,将下边的所有struct/struct数组的类型用“树节点ID”替换,最后输出时,再替换即可,替换时就处理了同名的情况,用父节点名字+当前名字
