go語言 base64編碼解碼

    str := "Man"
    fmt.Println("原字符串是：", str)
    enStr := Base64EncodeString(str)
    fmt.Println("編碼后字符串是：", enStr)
    deStrBytes, deStr := Base64DecodeString(enStr)
    fmt.Printf("解碼后字符串：字符串%s 字節%v\n", deStrBytes, deStr)

}

}

// Base64DecodeString 解碼

    resBytes, _ := base64.StdEncoding.DecodeString(str)
    return string(resBytes), resBytes
