Question

遇到此错误

InvalidOperationException：没有注册类型为'Microsoft.AspNetCore.Identity.UserManager`1 [Microsoft.AspNetCore.Identity.IdentityUser]'的服务。

我正在尝试将identityserver和asp.net身份ui纳入一个项目。

此http://docs.identityserver.io/en/dev/quickstarts/6_aspnet_identity.html#new-project-for-asp-net-identity文章之后，提供了所需的额外代码。我做了以下步骤

创建一个ASP.NET Core 2.2 MVC应用，单帐户身份验证
对其进行了测试，以确保其正常运行，注册用户，登录后一切正常。
添加了nuget包IdentityServer4.AspnetIdentity

在下面添加了Config.cs文件

public static class Config
{
public static IEnumerable<IdentityResource> GetIdentityResources()
{
    return new List<IdentityResource>
    {
        new IdentityResources.OpenId(),
        new IdentityResources.Profile(),
        new IdentityResources.Email(),
    };
}
public static IEnumerable<ApiResource> GetApiResources()
{
    return new List<ApiResource>
    {
        new ApiResource("eventsapi", "Events Api")
    };
}
public static IEnumerable<Client> GetClients()
{
    return new List<Client>
    {
        new Client
        {
            ClientId = "client",

            // no interactive user, use the clientid/secret for authentication
            AllowedGrantTypes = GrantTypes.ClientCredentials,

            // secret for authentication
            ClientSecrets =
            {
                new Secret("secret".Sha256())
            },

            // scopes that client has access to
            AllowedScopes = { "eventsapi" }
        }
    };
}
}

添加了ApplicationUser.cs

public class ApplicationUser:IdentityUser
{
}

修改后的Startup.cs（注释代码已生成）

  public class Startup
   {
     public Startup(IConfiguration configuration)
   {
      Configuration = configuration;
   }

public IConfiguration Configuration { get; }


public void ConfigureServices(IServiceCollection services)
{
    services.Configure<CookiePolicyOptions>(options =>
    {

        options.CheckConsentNeeded = context => true;
        options.MinimumSameSitePolicy = SameSiteMode.None;
    });

    services.AddDbContext<ApplicationDbContext>(options =>
        options.UseSqlServer(
            Configuration.GetConnectionString("DefaultConnection")));
    /*
    services.AddDefaultIdentity<IdentityUser>()
        .AddDefaultUI(UIFramework.Bootstrap4)
        .AddEntityFrameworkStores<ApplicationDbContext>();
    */
    //REPLACED ABOVE
    services.AddIdentity<ApplicationUser, IdentityRole>()
        .AddEntityFrameworkStores<ApplicationDbContext>()
        .AddDefaultTokenProviders();




    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

    //ADDDED
    services.AddIdentityServer()
        .AddDeveloperSigningCredential()
        .AddInMemoryPersistedGrants()
        .AddInMemoryIdentityResources(Config.GetIdentityResources())
        .AddInMemoryApiResources(Config.GetApiResources())
        .AddInMemoryClients(Config.GetClients())
        .AddAspNetIdentity<ApplicationUser>();

}


public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
        app.UseDatabaseErrorPage();
    }
    else
    {
        app.UseExceptionHandler("/Home/Error");
         app.UseHsts();
    }

    app.UseHttpsRedirection();
    app.UseStaticFiles();
    app.UseCookiePolicy();

    //app.UseAuthentication();
    //REPLACED ABOVE
    app.UseIdentityServer();
    app.UseMvc(routes =>
    {
        routes.MapRoute(
            name: "default",
            template: "{controller=Home}/{action=Index}/{id?}");
    });
}

}

Answer 1

对于此错误，请尝试在IdentityUser中更改Views\Shared\_LoginPartial.cshtml。

@using Microsoft.AspNetCore.Identity
@inject SignInManager<ApplicationUser> SignInManager
@inject UserManager<ApplicationUser> UserManager

<ul class="navbar-nav">
@if (SignInManager.IsSignedIn(User))
{
    <li class="nav-item">
        <a  class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Manage/Index" title="Manage">Hello @User.Identity.Name!</a>
    </li>
    <li class="nav-item">
        <form  class="form-inline" asp-area="Identity" asp-page="/Account/Logout" asp-route-returnUrl="@Url.Action("Index", "Home", new { area = "" })">
            <button  type="submit" class="nav-link btn btn-link text-dark">Logout</button>
        </form>
    </li>
}
else
{
    <li class="nav-item">
        <a class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Register">Register</a>
    </li>
    <li class="nav-item">
        <a class="nav-link text-dark" asp-area="Identity" asp-page="/Account/Login">Login</a>
    </li>
}
</ul>

然后，您需要注册AddDefaultUI，用于处理Startup.cs中的操作的身份区域请求，例如

services.AddIdentity<ApplicationUser, IdentityRole>()
    .AddDefaultUI(UIFramework.Bootstrap4)
    .AddEntityFrameworkStores<ApplicationDbContext>()
    .AddDefaultTokenProviders();

IdentityServer4和ASP.NET Core 2.2与ASP.NET Identity集成
