如何在 asp.net core 2.2 中使用 MVC 而不是剃刀页面

Question

从 asp.net core 2.1 开始，不支持 MVC 作为具有 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 。 我认为这将是一件简单的事情。 我错了。 那我做了什么：

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

6.1 ConcurrencyStamp

6.2 规范化用户名

6.3 规范化电子邮件

6.4 更名 LockoutEnd？ 到锁定结束

系统已构建，但我仍然无法使用帐户控制器。 我已按照https://docs.microsoft.com/en-us/aspnet/core/security/authentication/scaffold-identity?view=aspnetcore-2.2 中的步骤操作但无济于事。 似乎我所做的即使在我搭建了身份的脚手架之后，我也无法读取 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实现来说要么太高要么太窄。

包括我的启动部分

       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。

那么有什么建议吗？

Answer 1

目前尚不清楚您究竟在做什么，但听起来您已经将 Identity Razor 页面搭建到您的项目中。 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 UI）。 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 物理搭建到您的项目中。

Answer 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

1. 打开 MS SQL Server 管理工作室
2. 选择您的数据库
3. 开始新的查询
4. 运行下面的脚本并将YOUR_DATABASE替换为您的数据库名称
5. 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从数据类型nvarchar到int的更改。
