我通过在ApplicationUser
类中添加少量字段来扩展ASP NET标识架构,该字段派生自IdentityUser
。我添加的字段之一是FullName
。
现在,当我写User.Identity.Name
时,它会给我用户名,我正在寻找像User.Identity.FullName
这样的东西,它应该返回我添加的FullName。
不确定,如何实现这一点,我们将非常感谢任何指导。
感谢。

您可以在创建用户时将其添加到用户的声明中,然后将其作为来自User.Identity的声明进行检索:
await userManager.AddClaimAsync(user.Id, new Claim("FullName", user.FullName));
退却:
((ClaimsIdentity)User.Identity).FindFirst("FullName")
或者您可以直接获取用户并从user.FullName访问它:
var user = await userManager.FindById(User.Identity.GetUserId())
return user.FullName

在ApplicationUser类中,您会注意到一条评论(如果您使用标准MVC5模板),其中显示“在此处添加自定义用户声明”。
鉴于此,这是添加FullName的样子:
public class ApplicationUser : IdentityUser
{
public string FullName { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> 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));
return userIdentity;
}
}
使用此功能,当有人登录时,FullName声明将被放入cookie中。您可以像这样帮助访问它:
public static string GetFullName(this System.Security.Principal.IPrincipal usr)
{
var fullNameClaim = ((ClaimsIdentity)usr.Identity).FindFirst("FullName");
if (fullNameClaim != null)
return fullNameClaim.Value;
return "";
}
并使用这样的帮助:
@using HelperNamespace
...
@Html.ActionLink("Hello " + User.GetFullName() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
请注意,自定义用户声明存储在Cookie中,这比从数据库获取用户信息更好...为常用数据保存数据库命中。

我发现这很好用
<强>的AccountController:强>
private async Task SignInAsync(ApplicationUser user, bool isPersistent)
{
AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);
identity.AddClaim(new Claim("FullName", user.FullName));
identity.AddClaim(new Claim("Email", user.Email));
identity.AddClaim(new Claim("DateCreated", user.DateCreated.ToString("MM/dd/yyyy")));
AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);
}
身份的扩展方法:
public static class GenericPrincipalExtensions
{
public static string FullName(this IPrincipal user)
{
if (user.Identity.IsAuthenticated)
{
ClaimsIdentity claimsIdentity = user.Identity as ClaimsIdentity;
foreach (var claim in claimsIdentity.Claims)
{
if (claim.Type == "FullName")
return claim.Value;
}
return "";
}
else
return "";
}
}
在您的视图中
@Html.ActionLink("Hello " + User.FullName() + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" })

可以通过定义您自己的IIdentity
(也可能是IPrincipal
)并在为HTTP请求创建IPrincipal
时构建它(当引发PostAuthenticateRequest时)。
如何实施自己的IIDentity
和IPrincipal

How do I implement custom Principal and Identity in ASP.NET MVC?
答案 4 :(得分:2)
我通过执行以下操作解决了问题:
1 - 通过扩展IPrincipal
创建我自己的CustomPrincipal2 - 在每个请求经过身份验证后加载CustomPrincipal。
创建我自己的CustomPrincipal
interface ICustomPrincipal : IPrincipal
{
string UserId { get; set; }
string FirstName { get; set; }
string LastName { get; set; }
int CustomerId { get; set; }
}
public partial class CustomPrincipal : ClaimsPrincipal, ICustomPrincipal
{
#region IPrincipal Members
public new ClaimsIdentity Identity { get; private set; }
public new bool IsInRole(string role)
{
IdentityManager manager = new IdentityManager();
return manager.IsInRole(role, this.UserId);
}
#endregion
public CustomPrincipal(ApplicationUser user, IIdentity identity)
:base(identity)
{
this.Identity = new ClaimsIdentity(identity);
this.UserId = user.Id;
this.FirstName = user.FirstName;
this.LastName = user.LastName;
this.CustomerId = user.CustomerId;
this.DateCreated = user.DateCreated;
}
#region ICustomPrinicpal Members
public string UserId { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public int CustomerId { get; set; }
public DateTime DateCreated { get; set; }
#endregion
public string GetFullName()
{
return this.FirstName + " " + this.LastName;
}
}
在每个请求经过身份验证后加载CustomPrincipal
在Global.asax.cs中......
protected void Application_PostAuthenticateRequest(object sender, EventArgs e)
{
if (User.Identity.IsAuthenticated)
{
//At this point we need to get the user from the database based on the username.
ApplicationUser AppUser = ApplicationUserDB.GetByUserName(User.Identity.Name);
CustomPrincipal UserPrincipal = new CustomPrincipal(AppUser, User.Identity);
HttpContext.Current.User = UserPrincipal;
}
}
正如您在上面的代码中所看到的,我检索ApplicationUser
并将其传递给CustomPrincipal
的构造函数。然后我将新CustomPrincipal
分配给当前上下文。

将值存储到声明并阅读。
商店价值
public class ApplicationUser : IdentityUser
{
public string FullName { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
userIdentity.AddClaim(new Claim("FullName", this.FullName));
return userIdentity;
}
}
读取值
var FullName = "";
if (User != null)
{
var identity = (System.Security.Claims.ClaimsIdentity)Context.User.Identity;
var claim1 = identity.Claims.FirstOrDefault(c => c.Type == "FullName");
if (claim1 != null)
{
FullName = claim1.Value;
}
}

这应该可以解决问题:
User.Claims.Single(x => x.Type== "name").Value
答案 7 :(得分:0)
我尝试过了,而且行得通!
IdentityModels.cs / ApplicationUser类
// Add custom user claims here
userIdentity.AddClaim(new Claim("FullName", this.FullName));
_LoginPartialView
<li>
@Html.ActionLink("Hello " + (((ClaimsIdentity)User.Identity).FindFirst("FullName").Value) + " !", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
</li>
