asp.net-core Sessions in ASP.NET Core 1.0 Basic example of handling Session
Example
1)First, add dependency in project.json - "Microsoft.AspNetCore.Session": "1.1.0",
2)In startup.cs and add AddSession() and AddDistributedMemoryCache() lines to the ConfigureServices like this-
services.AddDistributedMemoryCache(); //This way ASP.NET Core will use a Memory Cache to store session variables
services.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromDays(1); // It depends on user requirements.
options.CookieName = ".My.Session"; // Give a cookie name for session which will be visible in request payloads.
});
3)Add the UseSession() call in Configure method of startup like this-
app.UseSession(); //make sure add this line before UseMvc()
4)In Controller, Session object can be used like this-
using Microsoft.AspNetCore.Http;
public class HomeController : Controller
{
public IActionResult Index()
{
HttpContext.Session.SetString("SessionVariable1", "Testing123");
return View();
}
public IActionResult About()
{
ViewBag.Message = HttpContext.Session.GetString("SessionVariable1");
return View();
}
}
- If you are using cors policy then sometimes it may give errors, after enabling
session regarding headers about enabling AllowCredentials header and using
WithOrigins header instead of AllowAllOrigins.
