Session Management in MVC

问题:

I am new in MVC. I am creating new WebApplication in MVC4 Razor. I want to maintain User Login session for all pages. Can any one Explain me how to maintain session for all views in MVC with small example.

回答1:

Session management is simple. Session object is available inside MVC controller and in HttpContext.Current.Session. It is the same object. Here is a basic example of how to use Session:

Write

Session["Key"] = new User("Login"); //Save session value

Read

user = Session["Key"] as User; //Get value from session

Answering your question

if (Session["Key"] == null){
   RedirectToAction("Login");
}

Check out Forms Authentication to implement highly secure authentication model.

UPDATE: For newer versions of ASP.NET MVC you should use ASP.NET Identity Framework. Please check out this article.

Here is a Example. Say we want to manage session after checking user validation, so for this demo only I am hard coding checking valid user. On account Login

public ActionResult Login(LoginModel model)
        {
            if(model.UserName=="xyz" && model.Password=="xyz")
            {
                Session["uname"] = model.UserName;
                Session.Timeout = 10;
                return RedirectToAction("Index");
            }
}

On Index Page

public ActionResult Index()
        {
            if(Session["uname"]==null)
            {
                return Redirect("~/Account/Login");
            }
            else
            {
                return Content("Welcome " + Session["uname"]);
            }
        }

On SignOut Button

Session.Remove("uname");
return Redirect("~/Account/Login");

Have you worked on Asp.Net application? Using Forms Authentication you can easily maintain user session.
