I want to save some treenode data as json so that I can use it in a web client. The orginal data looks like this:
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
I want to the json file to look like this.
{
"name": "root",
"children": [
{
"name": "Shopping",
"children": [
{
"name": "Housewares",
"children": [
{
"name": "Kitchen",
"leaf": "1"
},
{
"name": "Officer",
"leaf": "1"
}
]
},
{
"name": "Remodeling",
"children": [
{
"name": "Retile kitchen",
"leaf": "1"
},
{
"name": "Paint bedroom",
"children": [
{
"name": "Ceiling",
"leaf": "1"
}
]
},
{
"name": "Other",
"leaf": "1"
}
]
}
]
},
{
"name": "Misc",
"leaf": "1"
}
]
}
So far I have this code but I am stumped by the AddtoJson() function.
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, "
")
SaveTreetoJson(node, r.ID, depth+1)
}
}
}
func main() {
data := []Node{
{"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"},
}
SaveTreetoJson(data, "root", 0)
bytes, _:= json.Marshal(rootNode)
fmt.Println(string(bytes))
}
Can anyone help me? Thanks!
