如何在给定的时间点将 dash 应用程序的访问限制为单个用户？

Question

我有一个破折号 python 网络应用程序，我想在给定的时间点将此应用程序的访问权限限制为单个用户。我怎样才能做到这一点？有没有办法在第二个用户尝试访问事件时获取事件？

我前段时间实现了类似的东西。基本上，我根据时间条件更改了呈现的布局。就我而言，我想让我的应用程序在工作时间内运行。（从 08:00 到 19:00）。

@app.callback(Output("page-content", "children"), [Input("url", "pathname")])
def render_page_content(pathname):
    # ---------------------------------------------------
    if pathname == "/":
        # define working time for MILF services
        day_of_week = date.today().strftime("%A")
        now = datetime.datetime.now()
        working_days = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
        if day_of_week in working_days and (now.hour >= 8) and (now.hour < 19):
            # if working time is ok, render App page
            layout = html.Div([tab01.layout])
        else:
            # if working time is closed, render an Info Page
            layout = dcc.Markdown('''
            ### APP is not working now... See you soon !
             ###### Opening time : Monday - Friday 
             ###### Opening hours : 08:00 - 19:00
            '''),
        return layout

当不满足条件时，我会打印消息：“应用程序现在无法运行...稍后见！”
