I have a couple of example nested structs and need to serialize them. I am using the encoding/gob library, which should convert the struct data to bytes and the encoding/base64 library to convert the bytes to a readable base64 format. However, when I run my example code I get a serialization error error. I don't understand why this happens and how to fix the problem.
I followed this example: Golang serialize and deserialize back
Here is the code:
package main
import (
"bytes"
"encoding/base64"
"encoding/gob"
"errors"
"fmt"
)
type Hello struct {
greeting string
}
type Bye struct {
helloSaid Hello
byesaid Hello
}
func (b1 Bye) Serialize() (string, error) {
b := bytes.Buffer{}
e := gob.NewEncoder(&b)
err := e.Encode(b1)
if err != nil {
return string(b.Bytes()[:]), errors.New("serialization failed")
}
return base64.StdEncoding.EncodeToString(b.Bytes()), nil
}
func DeserializeBye(str string) (Bye, error) {
m := Bye{}
by, err := base64.StdEncoding.DecodeString(str)
if err != nil {
return m, errors.New("deserialization failed")
}
b := bytes.Buffer{}
b.Write(by)
d := gob.NewDecoder(&b)
err = d.Decode(&m)
if err != nil {
return m, errors.New("deserialization failed")
}
return m, nil
}
func main() {
h := Hello{greeting: "hello"}
b := Bye{helloSaid: h, byesaid: h}
serialized, err := b.Serialize()
if err != nil {
fmt.Println(err)
}
fmt.Println(serialized)
}
