Encode/Decode base64

Question

here is my code and i don\'t understand why the decode function doesn\'t work.

Little insight would be great please.

func EncodeB64(message string) (reto         


        

Answer 1

The len prefix is superficial and causes the invalid utf-8 error:

package main

import (
        "encoding/base64"
        "fmt"
        "log"
)

func main() {
        str := base64.StdEncoding.EncodeToString([]byte("Hello, playground"))
        fmt.Println(str)

        data, err := base64.StdEncoding.DecodeString(str)
        if err != nil {
                log.Fatal("error:", err)
        }

        fmt.Printf("%q\n", data)
}

Output

SGVsbG8sIHBsYXlncm91bmQ=
"Hello, playground"

EDIT: I read too fast, the len was not used as a prefix. dystroy got it right.
