扩展ASP.NET标识

Question

从许多方面来看,这似乎已被多次询问,但这些似乎都不适合我的确切情况.

这是我的_LoginPartial.cshtml文件中的一行:

@Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" })

请参阅说明User.Identity.GetUserName()的部分？

我想将其更改为User.Identity.FirstName或User.Identity.GetFirstName().

我不想让它说"你好电子邮件地址",而是"Hello Bob"

我的想法是,我只是想在Identity类上显示一个新属性(或方法).显然它必须不止于此.

我添加了FirstName属性,它在AccountController中可用.

public class ApplicationUser : IdentityUser
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }

它不会在_LoginPartial文件中公开.我希望它暴露在那里!

谢谢您的帮助

即使你的答案不是"完全"我想要的,你的评论也让我得到了这个解决方案:

@using Microsoft.AspNet.Identity
@using YourModelnameHere.Models
@if (Request.IsAuthenticated)
{
using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
{
    @Html.AntiForgeryToken()

    <ul class="nav navbar-nav navbar-right">
        <li>
            @{
                var manager = new UserManager<ApplicationUser>(new Microsoft.AspNet.Identity.EntityFramework.UserStore<ApplicationUser>(new ApplicationDbContext()));
                var currentUser = manager.FindById(User.Identity.GetUserId()); 
            }
            @Html.ActionLink("Hello " + currentUser.FirstName + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" })

            @Html.ActionLink("Hello " + User.Identity.GetUserName() + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" }) // I no longer need this ActionLink!!!
        </li>
    </ul>
    }
}

在我的IdentityModel.cs文件中,我添加了两个属性FirstName和LastName

public class ApplicationUser : IdentityUser
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

我通过在用户登录时向声明添加名字和姓氏,然后编写我自己的扩展方法来完成此操作.

当用户登录时,将所需的详细信息添加到声明集(AccountController)中:

private async Task SignInAsync(ApplicationUser user, bool isPersistent)
{
    AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);
    var identity = await UserManager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie);

    // Add the users primary identity details to the set of claims.
    var pocoForName = GetNameFromSomeWhere();

    identity.AddClaim(new Claim(ClaimTypes.GivenName, pocoForName));

    AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, identity);
}

扩展方法,它只是从用户的声明集中提取细节:

public static class IdentityExtensions
{
    public static IdentityName GetGivenName(this IIdentity identity)
    {
        if (identity == null)
            return null;

        return (identity as ClaimsIdentity).FirstOrNull(ClaimTypes.GivenName);
    }

    internal static string FirstOrNull(this ClaimsIdentity identity, string claimType)
    {
        var val = identity.FindFirst(claimType);

        return val == null ? null : val.Value;
    }
}

现在在partial中,只需调用新的扩展方法即可获得所需的详细信息:

@Html.ActionLink("Hello " + User.Identity.GetGivenName() + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "Manage" })

编辑:更新以更紧密地匹配SignInAsync()方法的原始海报版本

private async Task SignInAsync(ApplicationUser user, bool isPersistent) 
{ 
    AuthenticationManager.SignOut(DefaultAuthenticationTypes.ExternalCookie);  

    var identity = await user.GenerateUserIdentityAsync(UserManager);
    //add your claim here

    AuthenticationManager.SignIn(new AuthenticationProperties() 
        { 
            IsPersistent = isPersistent 
        }, identity);
}
