I have a Login Page with three fields Username, Password and a dropdown list. The User is supposed to a select a value from dropdown list before signing.
I need to store the selected value of dropdown list in the Authentication Cookie and Able to Retrieve it on further requests.
Using AspNetCore Identity 2.0.0 for authentication.
You can read up on how to do this on https://learn.microsoft.com/en-us/aspnet/core/security/authentication/cookie?tabs=aspnetcore2x
//somehow authenticate your user. I don't care how you do this.
var user = await AuthenticateUser(Input.Email, Input.Password);
//create a list of claims - all you need based on your user information
//this si also where you store the information based on your ddl value
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.Email),
new Claim("FullName", user.FullName),
new Claim("DropdownValue", /*ADD DROPDOWN VALUE HERE*/)
};
var claimsIdentity = new ClaimsIdentity(
claims, CookieAuthenticationDefaults.AuthenticationScheme);
var authProperties = new AuthenticationProperties();
await HttpContext.SignInAsync(
CookieAuthenticationDefaults.AuthenticationScheme,
new ClaimsPrincipal(claimsIdentity),
authProperties);
Eh voila. Done.
OnRefreshingPrincipal event to preserve your values.
