c# – 获取ASP.NET身份当前用户在视图中

我使用ASP.NET Identity 2.0和MVC.我需要登录用户名,姓,电子邮件等.怎么可以得到它?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 classpublic 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; }}解决方法 如果只有您需要获取的特定属性,您可以将它们作为您的ApplicationUser类中的声明添加,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类接线:

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”);

这里没有形式的认证机票.

如果您想要完整的用户详细信息,您可以随时创建一个扩展方法,如下所示:

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();

不过,如果您一直在打电话给我,建议您使用缓存.
