Golang中json和jsoniter的区别使用示例

package main
import (
	"fmt"
	"time"
	jsoniter "github.com/json-iterator/go"
	"github.com/json-iterator/go/extra"
)
type Order struct {
	Id         int64             `json:"id"`
	OrderId    string            `json:"order_id"`
	Money      float64           `json:"money"`
	CreateTime time.Time         `json:"create_time"`
	Extend     map[string]string `json:"extend"`
}
func main() {
	order := Order{
		Id:         666,
		OrderId:    "12345678",
		Money:      99.99,
		CreateTime: time.Now(),
		Extend:     map[string]string{"name": "张三"},
	}
	// 使用1:直接转成字符串
	jsonStr, _ := jsoniter.MarshalToString(order)
	fmt.Println("jsonStr:", jsonStr)
	// 使用2:直接转成字节数组
	jsonByteArr, _ := jsoniter.Marshal(order)
	fmt.Println("jsonByteArr:", jsonByteArr)
	// 使用3:反序列化之字符串转结构体
	str := `{"id":666, "order_id":"12345678", "money": 99.99, "create_time":"2023-12-05T16:19:33.943989108+08:00", "extend":{"name":"张三"}}`
	var order2 Order
	err := jsoniter.UnmarshalFromString(str, &order2)
	if err != nil {
		fmt.Println("err2:", err)
	}
	fmt.Println("order2:", order2)
	// 使用4:反序列化之字节数组转结构体
	var order3 Order
	var jsonNew = jsoniter.ConfigCompatibleWithStandardLibrary
	// 自适应类型
	extra.RegisterFuzzyDecoders()
	err = jsonNew.Unmarshal([]byte(str), &order3)
	if err != nil {
		fmt.Println("err3:", err)
	}
	fmt.Println("order3:", order3)
}
