使用golang将treenode保存为json文件？

导读：我想将一些treenode数据保存为json,以便我可以在Web客户端中使用它.原始数据如下所示： id parentId name leaf001 000 root 0002 001 Shooping 0003 002 Housewares 0004 003 Kitchen 1005 003 Officer 1006 002 Remodeling 0007 006 Retile kitchen 1008 00

我想将一些treenode数据保存为json,以便我可以在Web客户端中使用它.原始数据如下所示：

id  parentId    name        leaf
001 000 root            0
002 001 Shooping        0
003 002 Housewares  0
004 003 Kitchen     1
005 003 Officer     1
006 002 Remodeling  0
007 006 Retile kitchen  1
008 006 Paint bedroom   1
009 008 Ceiling         1   
010 006 Other       1
011 001 Misc        1

我希望json文件看起来像这样.

{
  "name": "root","children": [
    {
      "name": "Shopping","children": [
        {
          "name": "Housewares","children": [
            {
              "name": "Kitchen","leaf": "1"
            },{
              "name": "Officer","leaf": "1"
            }
          ]
        },{
          "name": "Remodeling","children": [
            {
              "name": "Retile kitchen",{
              "name": "Paint bedroom","children": [
                {
                  "name": "Ceiling","leaf": "1"
                }
              ]
            },{
              "name": "Other","leaf": "1"
            }
          ]
        }
      ]
    },{
      "name": "Misc","leaf": "1"
    }
  ]
}

到目前为止,我有这个代码,但我被AddtoJson()函数难倒.

package main
import (
    "fmt"
 "encoding/json"
)
type Node struct {
    ID string
    Name    string `json:"name"`
    Children []*Node  `json:"children"`
    Leaf  string    `json:"leaf"`
}
var rootNode *Node
func SaveTreetoJson(node []Node,parent string,depth int) {
    for _,r := range node {
        if r.parentID == parent {
            for i := 0; i < depth; i++ {
                AddtoJson(rootNode)//how to deal with the "AddtoJson" function  and the rootNode?
            }
            fmt.Print(r.Name,"nn")
            SaveTreetoJson(node,r.ID,depth+1)
        }
    }
}

func main() {
    data := []Node{
{"001","000","root","0"},{"002","001","Shooping",{"003","002","Housewares",{"004","003","Kitchen","1"},{"005","Officer",{"006","Remodeling",{"007","006","Retile kitchen",{"008","Paint bedroom",{"009","008","Ceiling",{"010","Other",{"011","Misc",}
    SaveTreetoJson(data,0)
 bytes,_:= json.Marshal(rootNode)
    fmt.Println(string(bytes)) 
}

谁能帮我？谢谢！

解决方法

this行的东西：

type Node struct {
    Id       string  `json:"-"`
    ParentId string  `json:"-"`
    Name     string  `json:"name"`
    Leaf     string  `json:"leaf,omitempty"`
    Children []*Node `json:"children,omitempty"`
}

func (this *Node) Size() int {
    var size int = len(this.Children)
    for _,c := range this.Children {
        size += c.Size()
    }
    return size
}

func (this *Node) Add(nodes... *Node) bool {
    var size = this.Size();
    for _,n := range nodes {
        if n.ParentId == this.Id {
            this.Children = append(this.Children,n)
        } else { 
            for _,c := range this.Children {
                if c.Add(n) {
                    break
                }
            }
        }
    }
    return this.Size() == size + len(nodes)
}
