如何在ASP.NET Core 2.1中使用角色? [英] How to use Roles in ASP.NET Core 2.1?

问题描述

我使用以下方法创建了一个测试项目:

I've created a test project using:

dotnet new razor --auth Individual --output Test

这将创建一个Startup.cs，其中包含:

This creates a Startup.cs that contains:

public void ConfigureServices(IServiceCollection services)
{
    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.UseSqlite(
            Configuration.GetConnectionString("DefaultConnection")));

    services.AddDefaultIdentity<IdentityUser>()
        .AddEntityFrameworkStores<ApplicationDbContext>();

    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
}

我想播种一些用户和角色.用户和角色都将使用相同的存储(SQLite).我正在使用静态类作为种子，从 Program 调用它.

I want to seed some users and roles. Both users and roles will use the same store (SQLite). I'm using a static class for seeding which it's called from Program.

我可以为用户提供种子，但不能为角色提供种子，因为上述内容似乎并未注入 RoleManager .

I can seed users, but not roles, since the above does not seem to inject a RoleManager.

在ASP.NET Core 2.0中，使用以下内容:

In ASP.NET Core 2.0 the following is used:

services.AddIdentity<IdentityUser, IdentityRole>()

我猜想 AddDefaultIdentity 在2.1中是新功能，但问题是它没有注入 RoleMnager ，所以我该怎么办?

I'm guessing AddDefaultIdentity is new in 2.1 but the problem is that it does not inject a RoleMnager, so what should I do?

推荐答案

看来，最终Microsoft明白并不是每个应用程序都需要角色并将它们分开.

It seems that finally Microsoft understood that not every application needs roles and separated them.

请注意， AddDefaultIdentity 声明为:

public static IdentityBuilder AddDefaultIdentity<TUser>(this IServiceCollection services) where TUser : class;

因此，您可以继续通过该 IdentityBuilder 配置身份"选项.您想做的是:

So, you can continue to configure Identity options through that IdentityBuilder. What you want to do is:

services.AddDefaultIdentity<IdentityUser>().AddRoles<IdentityRole>();

幸运的是，他们还删除了 IUser 和 IRole 约束，因此现在您可以在完全独立的程序集中使用模型，而不必安装数百个NuGet软件包.

Fortunately, they also removed the IUser and IRole constrains, so now you can use models in a completely separate assembly without having to install hundreds of NuGet packages.
