I am trying to decode a simple base64 encoded string in golang.
package main
import b64 "encoding/base64"
import fmt
func main() {
data := "YmFzZTY0IGVuY29kZWQgc3RyaW5n"
sDec, err1 := b64.StdEncoding.DecodeString(data)
fmt.Println(sDec)
fmt.Println(err1)
}
And the output I get is
[98 97 115 101 54 52 32 101 110 99 111 100 101 100 32 115 116 114 105 110 103] // this is the decoded data.
<nil>
Where as https://www.base64decode.net/ decodes and outputs as
base64 encoded string
How do I get the same result in golang?
StdEncoding.DecodeString(data)
(which is base64.Encoding.DecodeString()
) returns you the decoded data as byte slice ( []byte
), and this is what you see printed: the decimal representation of the individal bytes.
Convert the byte slice to string
if you want to see it as a string
value:
fmt.Println(string(sDec))
Or use a format string where you specify you want to print is as a string
:
fmt.Printf("%s\n", sDec)
Then the output will be (try it on the Go Playground ):
base64 encoded string
