c# - _ViewStart.cshtml 从不执行 SignInManager.IsSignedIn(User)

Question

我遇到了一个问题，我在登录后尝试对用户进行身份验证，但看起来 SignInManager.IsSignedIn(User) 总是错误的。我尝试了许多不同的方法，包括从以下位置更改 _LoginPartial：

@inject SignInManager<IdentityUser> SignInManager

@inject UserManager<IdentityUser> UserManager

至：

@inject SignInManager<User> SignInManager

@inject UserManager<User> UserManager

搞乱 Startup.cs 服务

我的 _LoginPartial.cshtml：

@using Microsoft.AspNetCore.Identity
@inject SignInManager<User> SignInManager
@inject UserManager<User> 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-controller="Account" asp-action="Register">Register</a>
        </li>
        <li class="nav-item">
            <a class="nav-link text-dark" asp-controller="Account" asp-action="Login">Login</a>
        </li>
    }
</ul>

我的 User.cs 类

{
    public class User: IdentityUser
    {
        override public string Id { get; set; }

        public virtual ICollection<Role> Roles { get; set; }


    }
}

*数据库上下文

public class ApplicationDbContext : IdentityDbContext<User>
    {
        public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options): base(options){ }

        public ApplicationDbContext()
        {
        }

        private string connectionString = ******

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder
                .UseMySql(connectionString, new MySqlServerVersion(new Version(8, 0, 25)))
                .UseLoggerFactory(LoggerFactory.Create(b => b
                    .AddConsole()
                    .AddFilter(level => level >= LogLevel.Information)))
                .EnableSensitiveDataLogging()
                .EnableDetailedErrors();
        }
    }

启动.cs

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

        public IConfiguration Configuration { get; }

        public void ConfigureServices(IServiceCollection services)
        {
            string mySqlConnectionStr = Configuration.GetConnectionString("DefaultConnection");
            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseMySql(mySqlConnectionStr, ServerVersion.AutoDetect(mySqlConnectionStr)));
            services.AddDefaultIdentity<User>()
            .AddEntityFrameworkStores<ApplicationDbContext>();
            services.AddScoped<SignInManager<User>, SignInManager<User>>();
            services.AddControllersWithViews();
            services.AddRazorPages();
            
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseDatabaseErrorPage();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }
            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
                endpoints.MapRazorPages();
            });
        }
    }

我一整天都在努力解决这个问题，所以任何建议都将不胜感激
