Cookies不存在（mvc5） [英] Cookies is not persist (mvc5)
问题描述
大家好，
条件中我有一个重叠div。
如果Cookies [ User]为null然后我显示overlay div有两个radio buttong和一个提交按钮。
当用户选择radio选项并单击submit按钮时，当通过ajax调用时，我正在调用一个动作，
哪个设置了cookie。
我在布局页面内推出了Overlay div，所以每次调用都要检查会话。
我的问题是：第一次设置cooikes之后，第二次没有持久。
以下是我设置cookie的方法：
public ActionResult SaveUserTypeCookies（string usertype，string returnUrl）
{
if（Request.Cookies [User]！= null ）
{
HttpCookie cookie = Request.Cookies [User];
cookie.Values [UserType] = usertype;
cookie.Expires = DateTime.MaxValue;
Response.SetCookie（cookie）;
}
else
{
HttpCookie cookie = new HttpCookie（User）;
cookie.Values [UserType] = usertype;
cookie.Expires = DateTime.MaxValue ;
Response.Cookies.Add（cookie）;
}
返回Redirect（returnUrl）;
以下是我对叠加div的说法：
@if（（Request.Cookies [User] == null））
{
Hello All,
I have one overlay div inside a condition.
If Cookies["User"] is null then I show overlay div having two radio buttong and one submit button.
When user select radio option and click submit button,when by ajax call ,I am calling an action ,
Which sets cookies.
I have putted Overlay div inside layout page,so for every call it checkes for session.
My issue is : First time after setting cooikes, it’s not persist for second time.
Below is my method which sets cookies:
public ActionResult SaveUserTypeCookies(string usertype, string returnUrl)
{
if (Request.Cookies["User"] != null)
{
HttpCookie cookie = Request.Cookies["User"];
cookie.Values["UserType"] = usertype;
cookie.Expires = DateTime.MaxValue;
Response.SetCookie(cookie);
}
else
{
HttpCookie cookie = new HttpCookie("User");
cookie.Values["UserType"] = usertype;
cookie.Expires = DateTime.MaxValue;
Response.Cookies.Add(cookie);
}
return Redirect(returnUrl);
Below is my contion for overlay div:
@if ((Request.Cookies["User"]== null))
{
}
}
推荐答案
以下链接将帮助您：
HTTP：//www.chwe。 at / 2009/01 / don-t-use-response.cookies-string - to-check-if-a-cookie-exists / [ ^ ]
有时DateTime.MaxValue也会引起麻烦，如下面链接所述：
http://stackoverflow.com/questions/6127123/net-datetime-maxvalue-is-different-once -it-is-stored-in-database [ ^ ]
因此C＃和JavaScript可能存在精度问题，所以尝试类似
DateTime.Now.AddHours（12）;
并检查它们是否在客户端设置。
如果可以，请尝试这些并分享成功。谢谢。
Below links will help you:

Sometime DateTime.MaxValue can also cause trouble as described in below link:
http://stackoverflow.com/questions/6127123/net-datetime-maxvalue-is-different-once-it-is-stored-in-database[^]
So there may be precision issue with C# and JavaScript, so try something like
DateTime.Now.AddHours(12);
and check whether they are setting at client side or not.
Try those and share if you can get success. Thanks.
