Cookie没有在C＃中设置 [英] Cookies not getting set in c#

问题描述

我正在使用cookie来了解是否已加载页面。因此，在asp.net c＃页面的页面加载中，我使用的是

I am using cookies to know whether a page was loaded before or not. So in page load of a asp.net c# page I am using this

if (Request.Cookies["PageLoaded"] == null)
{
   //Initialize things if page loading for first time.
}

并在if作为最后一个参数中设置如下所示的cookie值

and inside the if as last parameter I am setting the cookies value like given below

if (Request.Cookies["PageLoaded"] == null)
{
   //Initialize things if page loading for first time.

   //Set cookies value to indicate page has loaded before
   Response.Cookies["PageLoaded"].Value = "True";
}

当我在本地主机上运行时，它的工作正常。但是，当我为每次页面加载（回发事件）将其托管到服务器时，初始if语句为true（即cookie始终为null）并进入循环。

When I run in local host its working fine. But when I host it to server for each page load(Postback events) the initial if statement is true(ie cookie is always null) and going inside the loop.

Am我做错了吗？
如何在c＃中执行此操作？
谢谢

Am I doing something wrong? How can I do this in c#? Thanks

推荐答案

尝试设置cookie的失效日期，如果未设置cookie的失效日期，则默认情况下cookie，它将是非持久性的，并且仅作为会话信息的一部分存储，因此，当您关闭浏览器时，cookie将被丢弃，例如

Try setting an expiry date for your cookie, by default if you do not set an expiry date for the cookie it will be non-persistant and only stored as part of the Session information so when you close the browser the Cookie will be discarded e.g.

Response.Cookies["PageLoaded"].Value = "True";
Response.Cookies["PageLoaded"].Expires = DateTime.Now.AddDays(1);
