Session being lost between controllers Asp.net core

Question

User-183185495 posted

Ok I am using a session variable to store a case Id that is linked between tables. I am using .net 3.1 I just need this simple value passed between controllers It appears to only work within the current controller.

public void ConfigureServices(IServiceCollection services) {
 services.Configure<CookiePolicyOptions>(options =>
{
       options.CheckConsentNeeded = context => true; // consent required
       options.MinimumSameSitePolicy = SameSiteMode.None;
     });

      ervices.AddSession(opts =>
      {
         opts.Cookie.IsEssential = true; // make the session cookie Essential
      });
    ...
}

This is the second controller where i wish to read in the above session.

    public class VesselsController : Controller
    {
        private readonly MISDBContext _context;

        public VesselsController(MISDBContext context) {
            _context = context;
            GetCompanies();
        }
    // POST: Vessels/Create
    // To protect from overposting attacks, enable the specific properties you want to bind to, for 
    // more details, see http://go.microsoft.com/fwlink/?LinkId=317598.
    [HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> Create([Bind("Id,Name,CountryOfOrigon,CompanyId,IMONumber,Flag,Company,Country,CallSign,MMSI,VesselType,Active,isDeleted,isActive,CreatedDate,CreatedBy,MISObjectId,RelationShipId")] Vessels vessels)
    {
            if (ModelState.IsValid) {
                var realtionShipId = Int32.TryParse(HttpContext.Session.GetString("relationShipId"), out int resultRelationshipId);

                Int32.TryParse(HttpContext.Session.GetString("CaseId"), out Int32 resultCaseId);
                vessels.isActive = true;
                vessels.isDeleted = false;
                vessels.CreatedBy = HttpContext.Session.GetString("Intitals");
                vessels.LastModfiedDate = DateTime.Now;                
                vessels.CreatedDate = DateTime.Now;
                vessels.LastModfiedBy = HttpContext.Session.GetString("Intitals");                
                vessels.MISObjectId = resultCaseId;
                vessels.RelationShipId = resultRelationshipId;
                _context.Add(vessels);
                await _context.SaveChangesAsync();
                return RedirectToAction("Edit", "Relationships", new { Id = vessels.MISObjectId });

            }
            GetCompanies();
            return View(vessels);
        }
} 

Its this resultCaseId I have lost the variable and yes I have setup the configure middle ware.

     app.UseSession();

Hi,

I tested these codes according to your situation, this will not cause the session to be lost, I do not know which controller you are in or in what way to handle the session.

Try setting session timeout to 1 hours and try again.

services.AddSession(options =>
    {
        options.IdleTimeout = TimeSpan. FromHours(1); // 1 hours expiry
    });

You can check the tutorial called Sessions in ASP.NET Core for more information.
