golang中base64编码和解码

golang中base64的编码和解码可以用内置库encoding/base64

package main

import (

“encoding/base64”

“fmt”

“log”

)

func main() {

input := []byte(“hello golang base64 快乐编程http://www.01happy.com +~”)

// 演示base64编码
encodeString := base64.StdEncoding.EncodeToString(input)
fmt.Println(encodeString)

// 对上面的编码结果进行base64解码
decodeBytes, err := base64.StdEncoding.DecodeString(encodeString)
if err != nil {
    log.Fatalln(err)
}
fmt.Println(string(decodeBytes))

fmt.Println()

// 如果要用在url中，需要使用URLEncoding
uEnc := base64.URLEncoding.EncodeToString([]byte(input))
fmt.Println(uEnc)

uDec, err := base64.URLEncoding.DecodeString(uEnc)
if err != nil {
    log.Fatalln(err)
}
fmt.Println(string(uDec))

}

运行输出:

go run encode.go
