我使用ASP.NET Identity 2.0和MVC。我需要在视图中记录用户的姓名,姓氏,电子邮件等。怎么能得到它?我可以得到@ User.Identity,但没有我的用户类的属性。
//in my view, i need here my ApplicationUser class
<div>
@User.Identity.Name
</div>
//ApplicationUser class
public class ApplicationUser : IdentityUser<int, CustomUserLogin, CustomUserRole,
CustomUserClaim>
{
public ApplicationUser()
{
this.CreatedDate = DateTime.Now;
}
public DateTime CreatedDate { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string TaxOffice { get; set; }
}
如果只需要获取特定属性,则可以在ApplicationUser类中将它们添加为声明,如下例所示:
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser, int> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
userIdentity.AddClaim(new Claim("FullName", this.FullName));
// or use the ClaimTypes enumeration
return userIdentity;
}
这从Startup.Auth类连接起来:
SessionStateSection sessionStateSection = ConfigurationManager.GetSection("system.web/sessionState") as SessionStateSection;
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/account/login"),
CookieName = sessionStateSection.CookieName + "_Application",
Provider = new CookieAuthenticationProvider
{
// Enables the application to validate the security stamp when the user logs in.
OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, ApplicationUser, int>
(
validateInterval: TimeSpan.FromMinutes(30),
regenerateIdentityCallback: (manager, user) => user.GenerateUserIdentityAsync(manager),
getUserIdCallback: (id) => (id.GetUserId<int>())
)
}
});
然后,您可以访问声明(在视图或控制器中):
var claims = ((System.Security.Claims.ClaimsIdentity)User.Identity).Claims;
var claim = claims.SingleOrDefault(m => m.Type == "FullName");
这里没有表单身份验证票
如果您希望提供完整的用户详细信息,则可以始终创建如下所示的扩展方法:
public static ApplicationUser GetApplicationUser(this System.Security.Principal.IIdentity identity)
{
if (identity.IsAuthenticated)
{
using (var db = new AppContext())
{
var userManager = new ApplicationUserManager(new ApplicationUserStore(db));
return userManager.FindByName(identity.Name);
}
}
else
{
return null;
}
}
并称之为:
@User.Identity.GetApplicationUser();
但是,如果你这次打电话,我会建议缓存。
如果您使用.NET Core应用程序:
您可以轻松使用@inject
功能调用来注入UserManager
和SignInManager
。
在您的视图中添加以下内容:
@inject SignInManager<YourUserIdentity> SignInManager
@inject UserManager<YourUserIdentity> UserManager
注射后,您应该能够使用UserManager
和SignInManager
方法。例如:
@if (SignInManager.IsSignedIn(User))
{
<a asp-area="" asp-controller="Manage" asp-action="Index" title="Manage">Hello @UserManager.GetUserName(User)</a>
}
else
{
}
当需要引用当前登录用户时,请注意传递
User
对象。
希望这对任何人都很方便:)
从您必须使用的控制器获取有关用户的信息
User.Identity.GetUserId();
或者如果您想获得有关您班级内用户的信息
HttpContext.Current.User.Identity.GetUserId();
