我有几个嵌套结构示例,需要对其进行序列化。我正在使用encoding/gob
库,该库应将结构数据转换为字节,而encoding/base64
库将字节转换为可读的base64格式。但是,当我运行示例代码时,出现serialization error
错误。我不明白为什么会发生这种情况以及如何解决问题。
我遵循以下示例:Golang serialize and deserialize back
代码如下:
软件包主要
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)
}
