Access struct fields of type []byte using string

Question

Is there a way to access struct fields of type []byte with a string?

package main

import "fmt"
import "reflect"

type myStruct struct {
    string1 []byte
    string2 []byte
}

func main() {
    v := myStruct{[]byte("text"), []byte("text2")}
    fmt.Println(getField(&v, "string1"))
}

func getField(v *myStruct, field string) string {
    r := reflect.ValueOf(v)
    f := reflect.Indirect(r).FieldByName(field)
    return f.String()
}

In my example, the output string is: <[]uint8 Value>

I've already read the following examples, but these only access int or string values.

    return string(f.Bytes())
}
