	func checkAuthorization(c *gin.Context) (string, bool) {
	username := c.Param("username")
	t, _ := c.Get("userdata")

	// get user id
	m := model.GetModel()

	id := strconv.Itoa(int(u.ID))

This function exactly implements the function of middleware. Maybe refactor it into a middleware function is a good idea :D
