Store processed data from middleware

[Bean900]

Hey,
I built an application where the middle ware converts a token into a claim and then checks if that claim is valid. Now I don't want to do this token to claim conversion again in the actual processing of the request. What is the best way to store this prepared data from the middle ware process so that it is still available in the actual process of the request?

Thanks in advance for your help :)

Context has Set and Get methods that you can use.

func main() {
	e := echo.New()

	e.Use(middleware.Logger())
	e.Use(middleware.Recover())
	e.Use(func(next echo.HandlerFunc) echo.HandlerFunc {
		return func(c echo.Context) error {
			c.Set("claim", "claim") // add value to context store
			return next(c)
		}
	})

	e.GET("/", func(c echo.Context) error {
		claim, ok := c.Get("claim").(string) // extract value from context and cast it into string
		if !ok {
			return c.String(http.StatusInternalServerError, "missing claim or cast failure")
		}
		return c.String(http.StatusOK, claim)
	})

	if err := e.Start(":8080"); err != http.ErrServerClosed {
		log.Fatal(err)
	}
}
