如何使用Golang的反射机制遍历并断言包含指针类型的嵌套结构体？

type User struct {
    Name   string
    Age    int64
    Hobbys *Hobby
    Sex    string
}

type Hobby struct {
    Cars  *Car
    Games *Game
}

type Car struct {
    Brand string
    Color string
    Price string
}

type Game struct {
    Number int64
    Style  string
}

func main() {
    user := &User{
        Name: "张三",
        Age:  15,
        Hobbys: &Hobby{
            Cars: &Car{
                Brand: "奔驰",
                Color: "白色",
                Price: "100万",
            },
            Games: &Game{
                Number: 10000,
                Style:  "街机",
            },
        },
        Sex: "男",
    }
    traverse(user)
}

func traverse(a interface{}) {
    val := reflect.ValueOf(a)
    if val.Kind() == reflect.Ptr {
        val = val.Elem()
    }
    if val.Kind() != reflect.Struct {
        return
    }
    for i := 0; i < val.NumField(); i++ {
        field := val.Field(i)
        fieldType := val.Type().Field(i)
        fmt.Printf("Field Name: %s, Type: %s, Value: ", fieldType.Name, fieldType.Type)
        if field.Kind() == reflect.Ptr && !field.IsNil() {
            fmt.Println("Pointer")
            traverse(field.Interface())
        } else {
            fmt.Println(field.Interface())
        }
    }
}
