如何在MVC 5上设置会话变量过期时间? [英] How set a Session variable expired time on MVC 5?

问题描述

我需要生成一个验证码，例如: 1599 进行登录.

I need to Generate a Verification Code like: 1599 for Login.

登录时用户必须输入正确的号码.

The User must input correct number when Login in.

但是我的默认会话过期时间为 30分钟.

But My default session expired time is 30 minute.

我不想让验证码过期这么长时间.我只需要保持 1分钟. 那么，如何仅为验证码会话变量设置过期超时?

I don't want let the Verification Code expired time so long. I just need it keep only 1 minute. So How I set expired time out only for the Verification Code session variable?

更新1:

我不想更改全局会话的过期时间.我只需要 在登录前仅对验证码会话变量进行设置.

I don't want to change the global session expired time. I just need set only for the Verification Code session variable before login.

推荐答案

对不起，我终于使用了此解决方案:

Sorry guys, I finally use this solution:

生成验证码时，我会将其保存到会话中

when generate the Verification Code I will save it to session

Session["VerificationCode"] = code;

每个人都知道.但是时间呢?我更改它:

That's everybody knows. but how about the time? I change it :

Session["VerificationCode"] = code;
Session["VerificationTime"] = DateTime.Now; 

现在也节省会话时间.然后我可以在用户登录时找到它:

Now the time save in session too. Then I can find it when User Login:

 // Verification Code Expired
 if ((DateTime)Session["VerificationTime"]).AddMinutes(1) < DateTime.Now)
 {
       ModelState.AddModelError("VerificationCode", "Verification Code Expired!");
       return View(adminLogin);
 }
 // Verification Code Error
 if (Session["VerificationCode"].ToString().ToUpper() != adminLogin.VerificationCode.ToUpper())
 {
       ModelState.AddModelError("VerificationCode", "Verification Code Error");
       return View(adminLogin);
 }
