go 定义复杂的json数据
前端需要一种复杂的json数据
类似于
{
"citys":[{
"name":"哈哈",
"value":[128.33165,45.451897,3],
"symbolSize":2,
"itemStyle":
{
"normal":
{
"color": "#F58158"
}
}
}],
"moveLines":[{
"fromName":"哈哈",
"toName":"北京",
"coords":[[128.33165,45.451897,2],[116.407524,39.90403,-24]]
}]
};
以下是实现方法
package main
import (
"fmt"
"encoding/json"
)
type ItemStyle struct {
Color string `json:"color"`
}
type City struct {
Name string `json:"name"`
Value []interface{} `json:"value"`
SymbolSize int `json:"symbolSize"`
ItemStyle map[string]ItemStyle `json:"itemStyle"`
}
type MoveLines struct {
FromName string `json:"fromName"`
ToName string `json:"toName"`
Coords []interface{} `json:"coords"`
}
type All struct {
Citys []interface{} `json:"citys"`
MoveLines []interface{} `json:"moveLines"`
}
func doTest(gps1 float32,gps2 float32,name3 string) ([]byte) {
//alls := make([]All,1)
//citys := make([]City, 1)
//froms := make([]MoveLines, 1)
city := &City{}
city.Name = name3
city.Value = make([]interface{}, 3)
city.Value[0] = gps1
city.Value[1] = gps2
city.Value[2] = 3
city.SymbolSize = 2
city.ItemStyle = make(map[string]ItemStyle)
city.ItemStyle["normal"] = ItemStyle{"#F58158"}
from := &MoveLines{}
from.FromName = name3
from.ToName = "北京"
from.Coords = make([]interface{},2)
from.Coords[0] = [3]float32{gps1,gps2,2}
from.Coords[1] = [3]float32{116.407526,39.90403,-24}
//citys[0] = *city
//froms[0] = *from
all := &All{}
all.Citys = make([]interface{},1)
all.Citys[0] = *city
all.MoveLines = make([]interface{},1)
all.MoveLines[0] = *from
//alls[0] = *all
j, _ := json.Marshal(*all)
return j
}
func main() {
//alls := make([]All,1)
//
//citys := make([]City, 1)
//froms := make([]MoveLines, 1)
//
//city := &City{}
//city.Name = "延寿"
//city.Value = make([]interface{}, 3)
//city.Value[0] = 128.331644
//city.Value[1] = 45.451897
//city.Value[2] = 3
//city.SymbolSize = 2
//city.ItemStyle = make(map[string]ItemStyle)
//city.ItemStyle["normal"] = ItemStyle{"#F58158"}
//
//from := &MoveLines{}
//from.FromName = "延寿"
//from.ToName = "北京"
//from.Coords = make([]interface{},2)
//from.Coords[0] = [3]float32{128.331644,45.451897,2}
//from.Coords[1] = [3]float32{116.407526,39.90403,-24}
//
//citys[0] = *city
//froms[0] = *from
//
//all := &All{}
//all.Citys = make([]interface{},1)
//all.Citys[0] = citys
//all.MoveLines = make([]interface{},1)
//all.MoveLines[0] = froms
//
//alls[0] = *all
//
//j, _ := json.Marshal(alls)
//fmt.Printf("%s", j)
test:= doTest(128.331644,45.451897,"哈哈")
fmt.Printf("%s", test)
}
