.NET Core RC2 中的登录声明

我正在将 .NET 4.6 版本移植到 .NET Core RC2，并想知道如何在 .NET Core RC2 中执行以下操作。

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);
        userIdentity.AddClaim(new Claim("FullName", string.Format("{0} {1}", this.Firstname, this.Lastname)));
        userIdentity.AddClaim(new Claim("Organization", this.Organization.Name));
        userIdentity.AddClaim(new Claim("Role", manager.GetRoles(this.Id).FirstOrDefault()));
        userIdentity.AddClaim(new Claim("ProfileImage", this.ProfileImageUrl));
        // Add custom user claims here
        return userIdentity;
}

然后是 Identity 的扩展方法。

public static class IdentityExtensions
{
    public static string FullName(this IIdentity identity)
    {
        var claim = ((ClaimsIdentity)identity).FindFirst("FullName");
        // Test for null to avoid issues during local testing
        return (claim != null) ? claim.Value : string.Empty;
    }

    public static string Organization(this IIdentity identity)
    {
        var claim = ((ClaimsIdentity)identity).FindFirst("Organization");
        // Test for null to avoid issues during local testing
        return (claim != null) ? claim.Value : string.Empty;
    }

    public static string Role(this IIdentity identity)
    {
        var claim = ((ClaimsIdentity)identity).FindFirst("Role");
        // Test for null to avoid issues during local testing
        return (claim != null) ? claim.Value : string.Empty;
    }

    public static string ProfileImage(this IIdentity identity)
    {
        var claim = ((ClaimsIdentity)identity).FindFirst("ProfileImage");
        // Test for null to avoid issues during local testing
        return (claim != null) ? claim.Value : string.Empty;
    }
}

这给了我使用的结果User.Identity.ProfileImg(); etc..

抱歉让大家久等了！

我通过在创建用户时执行以下操作解决了这个问题。就我而言，当创建用户时，我创建了声明，这些声明存储为与用户的关系。 然后，我在整个过程中保持这些值的更新，这意味着每次有人更改这些值时，它们也必须在声明表中更新。

var user1 = new ApplicationUser()
{
    Firstname = "MyName",
    Lastname = "MyLastname",
    UserName = "[email protected] /cdn-cgi/l/email-protection",
    Email = "[email protected] /cdn-cgi/l/email-protection",
    EmailConfirmed = true,
    PhoneNumber = "000000000",
    OrganizationId = organization.Id,
    ProfileImageUrl = "user.jpg"
};
await userManager.CreateAsync(user1, "Qwerty1!");
await userManager.AddToRoleAsync(user1, "SuperAdmin");

var claims1 = new List<Claim> {
    new Claim("Email", user1.Email),
    new Claim("FullName", string.Format("{0} {1}", user1.Firstname, user1.Lastname)),
    new Claim("Organization", organization.Name),
    new Claim("Role", "SuperAdmin"),
    new Claim("ProfileImage", user1.ProfileImageUrl)
};

await userManager.AddClaimsAsync(user1, claims1);

最后但并非最不重要的一点是，我创建了扩展，以便当前登录用户在视图和控制器中访问这些内容。

using System.Security.Claims;
using System.Security.Principal;

namespace Core.Extensions
{
    public static class IdentityExtension
    {
        public static string FullName(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("FullName");
            return (claim != null) ? claim.Value : string.Empty;
        }

        public static string Organization(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("Organization");
            return (claim != null) ? claim.Value : string.Empty;
        }

        public static string Role(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("Role");
            return (claim != null) ? claim.Value : string.Empty;
        }

        public static string ProfileImage(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("ProfileImage");
            return (claim != null) ? claim.Value : string.Empty;
        }

        public static string Email(this IIdentity identity)
        {
            var claim = ((ClaimsIdentity)identity).FindFirst("Email");
            return (claim != null) ? claim.Value : string.Empty;
        }
    }

}

然后我可以使用在我看来是这样的例如

@using Microsoft.AspNetCore.Identity
@using Core.Extensions
@{
    ViewData["Title"] = "Overview";
}
<h4 class="mt-0 mb-5">Welcome back @User.Identity.FullName()</h4>
