How to encode struct to byte slice and decode byte slice back to original struct using gob encoding?
问题
你好！以下是你提供的代码的翻译版本：
package main
import (
"bytes"
"encoding/gob"
"fmt"
)
type object struct {
name string
age int
}
func main() {
inputObject := object{age: 22, name: "Zloy"}
fmt.Println(inputObject)
var inputBuffer bytes.Buffer
gob.NewEncoder(&inputBuffer).Encode(inputObject)
fmt.Println(inputBuffer)
destBytes := inputBuffer.Bytes()
fmt.Println("\n", destBytes, "\n")
var outputBuffer bytes.Buffer
outputBuffer.Write(destBytes)
fmt.Println(outputBuffer)
var outputObject object
gob.NewDecoder(&outputBuffer).Decode(&outputObject)
fmt.Println(outputObject)
}
输出结果：
{Zloy 22}
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0]
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
{ 0}
期望的输出结果：
{Zloy 22}
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0]
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
{Zloy 22}
你的代码看起来没有问题，输出结果也与预期一致。如果你有其他问题，请告诉我。

i am trying marshall go struct to bytes (via gob encoding), and then to unmarshall those bytes back to original object. I am getting unexpected result (object is not getting the correct values). Help me to correct the programm please.
Input:
package main
import (
"bytes"
"encoding/gob"
"fmt"
)
type object struct {
name string
age int
}
func main() {
inputObject := object{age: 22, name: "Zloy"}
fmt.Println(inputObject)
var inputBuffer bytes.Buffer
gob.NewEncoder(&inputBuffer).Encode(inputObject)
fmt.Println(inputBuffer)
destBytes := inputBuffer.Bytes()
fmt.Println("\n", destBytes, "\n")
var outputBuffer bytes.Buffer
outputBuffer.Write(destBytes)
fmt.Println(outputBuffer)
var outputObject object
gob.NewDecoder(&outputBuffer).Decode(&outputObject)
fmt.Println(outputObject)
}
Output:
{Zloy 22}
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0]
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
{ 0}
Expected Output:
{Zloy 22}
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0]
{[18 255 129 3 1 1 6 111 98 106 101 99 116 1 255 130 0 0 0] 0 0}
{Zloy 22}

你需要将字段名称大写，以便可以公开导出/导入它们：
type object struct {
Name string
Age int
}

英文:
You need to capitalize the field names to make them publicly exportable/importable:
type object struct {
Name string
Age int
}
