golang的json操作

package main

import (
    "encoding/json"
    "fmt"
)

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

func main() {
    fmt.Println("go")
    //简单的反解json
    aBook := make(map[string]interface{})
    aBook["name"] = "空"
    aBook["price"] = 11.2
    aBook["pub_age"] = 11
    jstr,err := json.Marshal(aBook)
    if err != nil {
        fmt.Println("json encode faild")
        return
    }
    fmt.Println(jstr,string(jstr))

    jstr2 := make(map[string]interface{})
    err = json.Unmarshal(jstr,&jstr2)
    if err != nil {
        fmt.Println("json decode faild")
        return
    }
    fmt.Println(jstr2)

}
