13 json序列化
1. encoding/json包
下面演示了标准库中的序列化函数json.Marshal和反序列化函数json.Unmarshal。
package main
import (
"encoding/json"
"fmt"
)
type Student struct {
Name string
Age int
Gender bool
}
type Class struct {
Id string
Students []Student
}
func main() {
s := Student{"小明", 20, true}
c := Class{"1班", []Student{s, s, s}}
bytes, err := json.Marshal(c)
if err != nil {
fmt.Println("序列化错误", err)
return
}
fmt.Println(string(bytes))
var c2 Class
err = json.Unmarshal(bytes, &c2)
if err != nil {
fmt.Println("反序列化失败", err)
}
fmt.Printf("%+v", c2)
}

字节跳动的json序列化库。比标准库更快。
package main
import (
"fmt"
"github.com/bytedance/sonic"
)
type Student struct {
Name string
Age int
Gender bool
}
type Class struct {
Id string
Students []Student
}
func main() {
s := Student{"小明", 20, true}
c := Class{"1班", []Student{s, s, s}}
bytes, err := sonic.Marshal(c)
if err != nil {
fmt.Println("序列化错误", err)
return
}
fmt.Println(string(bytes))
var c2 Class
err = sonic.Unmarshal(bytes, &c2)
if err != nil {
fmt.Println("反序列化失败", err)
}
fmt.Printf("%+v", c2)
}
