Access Claim values in controller in MVC 5
I have used OWIN authentication in my application.
Login Action
var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, result.UserFirstName));
claims.Add(new Claim(ClaimTypes.Sid, result.UserID.ToString()));
var identity = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);
I want to access the UserName and UserID from different action. How can I access the values which is added in the claims?
Update I have tried
var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, result.UserFirstName + " " + result.UserLastName));
claims.Add(new Claim(ClaimTypes.Sid, result.UserIDNumber.ToString()));
var identity = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);
var authenticationManager = Request.GetOwinContext().Authentication;
authenticationManager.SignIn(identity);
var claimsPrincipal = new ClaimsPrincipal(identity);
Thread.CurrentPrincipal = claimsPrincipal;
I can view the values inside the quick window. But even though I couldn't access the value. How to get the value?
You need to set your Thread.CurrentPrincipal
after login i.e.
var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, result.UserFirstName));
claims.Add(new Claim(ClaimTypes.Sid, result.UserID.ToString()));
var identity = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);
var claimsPrincipal = new ClaimsPrincipal(identity);
// Set current principal
Thread.CurrentPrincipal = claimsPrincipal;
Then the following will retrieve the values.
//Get the current claims principal
var identity = (ClaimsPrincipal)Thread.CurrentPrincipal;
// Get the claims values
var name = identity.Claims.Where(c => c.Type == ClaimTypes.Name)
.Select(c => c.Value).SingleOrDefault();
var sid = identity.Claims.Where(c => c.Type == ClaimTypes.Sid)
.Select(c => c.Value).SingleOrDefault();
Here is another example, with custom claim types as well:
Login:
var claims = new List<Claim>
{
new Claim(ClaimTypes.Name, user.Name, ClaimValueTypes.String),
new Claim(ClaimTypes.Email, user.Email ?? string.Empty, ClaimValueTypes.Email),
new Claim(ClaimTypes.PrimarySid, user.Id.ToString(), ClaimValueTypes.Integer),
new Claim(CustomClaimTypes.SalesId, user.SalesId.ToString(), ClaimValueTypes.Integer)
};
var claimsIdentity = new ClaimsIdentity(claims, DefaultAuthenticationTypes.ApplicationCookie);
AuthenticationManager.SignIn(claimsIdentity);
Custom claims:
public static class CustomClaimTypes
{
public const string SalesId = "SalesId";
}
Extension methods:
public static class IdentityExtensions
{
public static int GetSalesId(this IIdentity identity)
{
ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
Claim claim = claimsIdentity?.FindFirst(CustomClaimTypes.SalesId);
if (claim == null)
return 0;
return int.Parse(claim.Value);
}
public static string GetName(this IIdentity identity)
{
ClaimsIdentity claimsIdentity = identity as ClaimsIdentity;
Claim claim = claimsIdentity?.FindFirst(ClaimTypes.Name);
return claim?.Value ?? string.Empty;
}
}
Can then be accessed like this:
User.Identity.GetSalesId();
User.Identity.GetName();
