解码

func Unmarshal(data []byte, v interface{}) error

json TO struct在线转译 ：http://json2struct.mervine.net/

json to go滴滴团队研发（据说比官方快6倍）：https://github.com/json-iterator/go

Warning:Json转结构体，或结构体转Json，结构体首字母必须大写！！！

​
package main

import (
    "fmt"
    "encoding/json"
)

func main() {
    type Student struct {
        Name string
        Age int
        Classes []string
        Prices float64
    }

    st := &Student {
        "xiaoming",
        18,
        []string{"math","english","chinese"},
        9.99,
    }

    result, err := json.Marshal(st)
    if(err == nil) {
        fmt.Println(string(result))
    }
    
}   

//{"Name":"xiaoming","Age":18,"Classes":["math","english","chinese"],"Prices":9.99}
