似乎go slice append（string）在我将其渲染到模板时更改了所有项（也在我将slice记录到终端时）我认为这是一个golang的事情，但我不确定with Django template
更新了代码，但我仍然有同样的问题with mutex and regular Html template

package main
import (
    "log"
    "sync"
    "github.com/gofiber/fiber/v2"
    "github.com/gofiber/template/html"
)
func main() {
    engine := html.New("./views", ".html")
    app := fiber.New(fiber.Config{
        Views: engine,
    })
    type Whatever struct {
        Whatever string `json:"whatever" form:"whatever"`
    }
    var (
        itemsMu sync.RWMutex
        items   = []string{}
    )
    app.Get("/", func(c *fiber.Ctx) error {
        itemsMu.RLock()
        defer itemsMu.RUnlock()
        return c.Render("index", fiber.Map{
            "Title": "Hello, World!",
            "Slice": items,
        })
    })
    app.Post("/", func(c *fiber.Ctx) error {
        w := new(Whatever)
        if err := c.BodyParser(w); err != nil {
            return err
        }
        itemsMu.Lock()
        items = append(items, w.Whatever)
        log.Println(items)
        itemsMu.Unlock()
        return c.Redirect("/")
    })
    log.Fatal(app.Listen(":3000"))
}
