如何在 asp.net core 2.2 中使用 MVC 而不是 razor 页面的身份答案

【问题标题】：How to make Identity use of MVC instead of razor pages in asp.net core 2.2如何在 asp.net core 2.2 中使用 MVC 而不是 razor 页面的身份

【问题描述】：

自 asp.net core 2.1 起，MVC 不支持作为带有 Identity 的默认模型。我想在 asp.net core 2.2 中使用 MVC 运行 Identity

长话短说。这是一个带有本地数据库的 asp.net 4.6.2 站点，我想升级到 asp.net core 2.2 。我认为这将是简单的事情。我错了。那我做了什么：

使用本地身份创建了一个新的 ASP.net core 2.0 项目
首先使用 Scaffold-DbContext 将 ef 上下文与数据库搭建起来
已修复，以便在启动时正确加载 EF。
从 Scaffold-Dbcontext 生成的脚手架中删除了 aspnetusers、aspnetuserroles、aspnetuserlogin、aspnetroles 模型
将 ApplicationDbContext 更新为继承自 IdentityDbContext。 ApplicationUser 继承自 IdentityUser
在我假装迁移已应用后，我在 aspnetusers 中手动添加了以下列

6.1 并发标记

6.2 标准化用户名

6.3 标准化电子邮件

6.4 改名 LockoutEnd?到LockoutEnd

系统已构建，但我仍然无法使用 Account 控制器。我已按照https://docs.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity?view=aspnetcore-2.2 中的步骤进行操作无济于事。看来我所做的即使在我搭建了身份之后也无法让它读取 mvc 控制器。

我认为，在 asp.net core 2.X Identity 中，Identity 实现的差异对于早期的实现来说要么太高，要么太窄。

包含在我的启动中

       services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });

        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(
                Configuration.GetConnectionString("DefaultConnection")));
        services.AddIdentity<ApplicationUser, IdentityRole>()
            // services.AddDefaultIdentity<IdentityUser>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1)
            .AddRazorPagesOptions(options =>
            {
                options.AllowAreas = true;
                //options.Conventions.AuthorizeAreaFolder("Identity", "/Account/Manage");
                //options.Conventions.AuthorizeAreaPage("Identity", "/Account/Logout");
            });

        services.ConfigureApplicationCookie(options =>
        {
            options.LoginPath = $"/Account/Login";
            options.LogoutPath = $"/Account/Logout";
            options.AccessDeniedPath = $"/Account/AccessDenied";
        });

        // using Microsoft.AspNetCore.Identity.UI.Services;
        services.AddSingleton<IEmailSender, EmailSender>();
    }

我想将 MVC 与 Identity Core 2.2 与来自 Identity .Net 的旧数据库一起使用。

有什么建议吗？

【解决方案1】：

不清楚您到底在做什么，但听起来您已经将 Identity Razor Pages 搭建到您的项目中。如果是这种情况，这些将优先于您的控制器，因为它是一条更物理的路线。

所有其他代码看起来都不错。您使用的是AddIdentity 而不是AddDefaultIdentity（因此不包括默认用户界面）。假设您实际上已经创建了一个 AccountController 并且您的路由设置正确，那么它应该可以工作，只要您没有将默认 UI 物理地搭建到您的项目中。

【讨论】：

好的.. 这行得通，我会将其设置为答案。但是 Accountcontroller 需要位于名为 Identity 的区域才能工作。为什么我不知道，但它似乎是在最新的 Identity 核心中硬编码

【解决方案2】：

最近我也做了同样的事情。以下内容可能对您有所帮助。首先为所有 AspNet 表创建等效的 Application 表。下面的 MS SQL Server 脚本将创建：

dbo.ApplicationRole
dbo.ApplicationRoleClaim
dbo.ApplicationUser
dbo.ApplicationUserClaim
dbo.ApplicationUserLogin
dbo.ApplicationUserRole
dbo.ApplicationUserToken

打开 MS SQL Server Management Studio
选择您的数据库
开始新查询
运行以下脚本并将 YOUR_DATABASE 替换为您的数据库名称
接下来，您应该将即将过时的 AspNet 表的内容复制到新的 Application 表中。在此过程中，您还应该处理 UserId 和 RoleId 的数据类型从 nvarchar 到 int 的更改。

USE [YOUR_DATABASE]
