c# - 启用 UseAuthentication 无法到达 HomeController 路由

问题描述

正如标题所说，我想在 .NET Core 2.1 中实现某种授权，但是我在学习他们的教程时遇到了麻烦。我已经设置了 Startup.cs 文件

public void ConfigureServices(IServiceCollection services)
    {

        string connection = Configuration.GetConnectionString("DefaultConnection");
        if (_currentEnvironment.IsDevelopment())
            services.AddDbContext<PagesContext>(options => options.UseSqlServer(connection), ServiceLifetime.Singleton);
        else
            services.AddDbContext<PagesContext>(options => options.UseMySql(connection), ServiceLifetime.Singleton);

        services.AddIdentity<User, IdentityRole>(opts=>
        {
            opts.Password.RequireDigit = false;
            opts.Password.RequiredLength = 8;
            opts.Password.RequireLowercase = false;
            opts.Password.RequireNonAlphanumeric = false;
            opts.Password.RequireUppercase = false;
            opts.User.AllowedUserNameCharacters = null;
        }).AddEntityFrameworkStores<PagesContext>()
        .AddDefaultTokenProviders();

        services.AddSingleton<IStringLocalizerFactory, EFStringLocalizerFactory>();
        services.AddMvc();

    }


    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseStatusCodePages();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }
        var supportedCultures = new[]
        {
            new CultureInfo("en-US"),
            new CultureInfo("en-GB"),
            new CultureInfo("en"),
            new CultureInfo("ru-RU"),
            new CultureInfo("ru"),
            new CultureInfo("uk-UA"),
            new CultureInfo("ua")
        };
        app.UseRequestLocalization(new RequestLocalizationOptions
        {
            DefaultRequestCulture = new RequestCulture("ru-RU"),
            SupportedCultures = supportedCultures,
            SupportedUICultures = supportedCultures
        });
        app.UseStaticFiles();
        app.UseAuthentication();
        app.UseMvc(
            routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            }
        );

我有包含以下内容的 HomeController.cs 文件：

    [HttpGet]
    public async Task<IActionResult> Index()
    {

        var user = await _userManager.GetUserAsync(HttpContext.User);
        if (user != null)
        {
            if (await _userManager.IsInRoleAsync(user, "Admin"))
            {
                return LocalRedirectPermanent("/Admin/Index");
            }
            else if (await _userManager.IsInRoleAsync(user, "Carrier"))
            {
                return LocalRedirectPermanent("/Carrier/Index");
            }
            return LocalRedirectPermanent("/Passenger/Index");
        }
        Page indexPage = db.Page.Include(u => u.Title).Include(u => u.Description).FirstOrDefault(p => p.Tag == "main_page");
        return View();
    }

从我要检测的代码中可以看出，如果用户登录 - 显示相应的页面。如果不是 - 页面，它启用登录过程。但是，当使用身份验证时，默认路由会被忽略。如果我从 Visual Studio 启动它，它会将我导航到 /Account/AccessDenied?ReturnUrl=%2FPassenger%2FIndex ，而不是 /Home/Index。我怎样才能覆盖这个？
