无法在 dotnet Core 2.1 中创建新角色

Question

我一直在阅读 dotnet 核心身份验证文档并尝试做一些示例。我能够创建新用户，但我运行遇到了创建新角色的问题。当我调用 RoleManager.CreateAsync 时，它不会创建新角色。

ApplicationContext Class:

  public class ApplicationDbContext : IdentityDbContext<ApplicationUser, IdentityRole<string>, string>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options)
            : base(options)
        {

        }
     }

startup.cs:

   services.AddDbContext<ApplicationDbContext>(options =>
        options.UseSqlServer(
            Configuration["AppSetting:DefaultConnection"]));

    services.AddIdentity<ApplicationUser, IdentityRole<string>>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();

我的存储库：

 private readonly UserManager<ApplicationUser> _userManager;
        private readonly SignInManager<ApplicationUser> _signManager;
        private readonly ApplicationDbContext _context;
        private readonly RoleManager<IdentityRole<string>> _roleManager;
        public AccountRespository(UserManager<ApplicationUser> userManager, SignInManager<ApplicationUser> signManager, ApplicationDbContext context, RoleManager<IdentityRole<string>> roleManager)
        {
            _signManager = signManager;
            _userManager = userManager;
            _context = context;
            _roleManager = roleManager;
        }

我在转发中创建角色的方法

public async Task CreateRoles(string roleName)
        {
            await _roleManager.CreateAsync(new IdentityRole() { Name = "Admin" });
        }

Answer 1

当我调用 CreateRole 方法时，上下文已被释放。我将 create 方法添加到接口并从控制器调用它。它现在按预期工作。
