I'm trying to use sessions to store variables in .net6, but the values are not getting stored-CodePudding

I'm trying to use sessions to store variables in .net6, I already configured program.cs but the session still not storing the values, using .net6 core with c#.

using Microsoft.EntityFrameworkCore;
using nsaprojeto.Data;


var builder = WebApplication.CreateBuilder(args);

builder.Services.AddDistributedMemoryCache();

builder.Services.AddSession(options =>
{
    options.IdleTimeout = TimeSpan.FromSeconds(10);
    options.Cookie.HttpOnly = true;
    options.Cookie.IsEssential = true;
});



// Add services to the container.
builder.Services.AddControllersWithViews();
builder.Services.AddDbContext<ApplicationDbContext>(options =>options.UseSqlServer(
    builder.Configuration.GetConnectionString("DefaultConnection")
    ));

var app = builder.Build();

// Configure the HTTP request pipeline.
if (!app.Environment.IsDevelopment())
{
    app.UseExceptionHandler("/Home/Error");
    // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
    app.UseHsts();
}

app.UseHttpsRedirection();
app.UseStaticFiles();

app.UseRouting();

app.UseAuthorization();

app.UseSession();
app.MapControllerRoute(
    name: "default",
    pattern: "{controller=L_AccessPoint}/{action=Filtros1}");

app.Run();

Thats the code that i'm using to set the session variable but that isnt storing the variable, Im doing something wrong, or forgetting something.

HttpContext.Session.SetString("adad", "dwdwwww");

EDIT: I have the following object and i need to store that in the session variables is that possible to do?

    public class L_AccessPoint
    {

        public string ap_name { get; set; }
        public short? zone_id { get; set; }
        public decimal? latitude { get; set; }
        public decimal? longitude { get; set; }
        public string ap_eth_mac { get; set; }
        public DateTime ts { get; set; }
        public short ap_id { get; set; }
        public Byte? type { get; set; }
        public bool Active { get; set; }

    }

In controller, you can do like below:

public class HomeController : Controller
{

    public IActionResult Index()
    {
        ISession session = HttpContext.Session;
        session.SetString("Username", "ffff");           
        return View();
    }
   
    public IActionResult Privacy()
    {     
        ISession session = HttpContext.Session;
       string username = session.GetString("Username");
        return View();
    }

    
}

CodePudding user response：

You can use HttpContext.Session.Set(string key, byte[] value) to achieve. Serialize your class to byte[] first and set session, Then get session and deserialize byte[] to your type

demo

public class Test
{
    public int Id { get; set; }
    public string Name { get; set; }
}

Set session

//For testing convenience，I just hard code here.

List<Test> test = new List<Test>()
    {
        new Test()
        {
            Id = 1,
            Name = "AAA"
        },
        new Test()
        {
            Id = 2,
            Name = "BBB"
        }
    };


IHttpContextAccessor.HttpContext.Session.Set("Test",JsonSerializer.SerializeToUtf8Bytes(test));

Get session

// result is a value of type[], You need deserialize it to your type
var result = IHttpContextAccessor.HttpContext.Session.Get("Test");

var test = JsonSerializer.Deserialize<List<Test>>(result);

result
