json-go-struct

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

  1. 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
  2. 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

I used https://github.com/mholt/json-to-go to get nested golang struct , nice project , much appreciated!!!
