package main

import (
	"encoding/base64"
	"fmt"
)

func main() {
	var msg =[]byte("i am the reader!")
	encoding := base64.StdEncoding.EncodeToString(msg)
	fmt.Println(encoding)
	bytes, e := base64.StdEncoding.DecodeString(encoding)
	if e!=nil{
		fmt.Println(e)
	}
	fmt.Println(string(bytes))
}

输出结果为：

i am the reader!
是不是很简单呢！
