c# - 在 MVC 5 的 Controller 中访问声明值

Question

我在我的应用程序中使用了 OWIN 身份验证。

登录操作

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);

我想通过不同的操作访问 UserName 和 UserID。我如何访问声明中添加的值？

更新我试过了

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;

我可以在快速窗口中查看值。但即使我无法访问该值。如何获取值？

Answer 1

您需要在登录后设置您的Thread.CurrentPrincipal 即

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;

然后以下将检索值。

//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();
