Question
Session variable value is getting null in ASP.NET Core
I am setting a session variable in one method and trying to get the session variable value from the another method in a controller but its always getting null:
Here is my code:
public class HomeController : Controller
{
public IActionResult Index()
{
HttpContext.Session.SetString("Test", "Hello!");
var message = HttpContext.Session.GetString("Test");// Here value is getting correctly
return View();
}
public IActionResult About()
{
var message = HttpContext.Session.GetString("Test"); // This value is always getting null here
return View();
}
}
Here is my session configuration in Startup
class:
In ConfigureServices()
method:
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
services.AddDistributedMemoryCache();
services.AddMvc().AddSessionStateTempDataProvider();
services.AddSession(options =>
{
options.Cookie.Name = "TanvirArjel.Session";
options.IdleTimeout = TimeSpan.FromDays(1);
});
In Configure()
method:
app.UseSession();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
Very strange and peculiar problem! Any help will be highly appreciated!
