08.go语言解析json

要定定义的结构体必须与json结构保持一致，如例子。

package main

import (
"encoding/json"
"log"
)

type GL struct {
Id    int
Name  string
Start int
End   int
}

type GL_slice struct {
FruitGL []GL
}

func main() {
str := `{"fruitGL": [{"Id":1,"Name":"aaa","start":3,"end":5}, {"Id":1,"Name":"aaa","start":3,"end":6}]}`

var msg GL_slice
err := json.Unmarshal([]byte(str), &msg)

if err != nil {
log.Println("Can't decode json message", err)
return
}

log.Println(msg)

}
