在 ASP.Net MVC Core 2.0 中设置登录 url

Question

由于我在身份验证相关方面不够好，我想将自定义身份验证移植到“.Net Core 2.0”，我需要帮助。那里有几个类似的问题，但我的有点不同。用户可以轻松登录和注销项目，只需要设置登录URL用户未登录时应该重定向到登录页面。

我已经检查过（this, 或其他几个页面，但它们大多已过时 - 与旧版本相关 - 或者它们不适合我的情况） 我的 Startup.cs:

// This method gets called by the runtime. Use this method to add services to the container.
    // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
    public void ConfigureServices(IServiceCollection services)
    {
        var builder = services.AddMvc(options => {
            options.ModelBinderProviders.Insert(0, new Olive.Mvc.OliveBinderProvider());
        })
        .AddJsonOptions(options =>
        {
            options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver();
        })
        .ConfigureApplicationPartManager(manager =>
        {
            var oldMetadataReferenceFeatureProvider = manager.FeatureProviders.First(f => f is MetadataReferenceFeatureProvider);
            manager.FeatureProviders.Remove(oldMetadataReferenceFeatureProvider);
            manager.FeatureProviders.Add(new ReferencesMetadataReferenceFeatureProvider());
        }); ;

        services.AddSingleton<IUserStore<User>, UserStore>();
        services.AddSingleton<IRoleStore<string>, RoleStore>();
        services.AddIdentity<User, string>();
        services.AddAuthentication(IdentityConstants.ApplicationScheme)
            .AddCookie(opt => opt.LoginPath = "/login");

        // Adds a default in-memory implementation of IDistributedCache.
        services.AddDistributedMemoryCache();

        services.AddSession();
    }

    // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
    public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseAuthentication();

        app.UseStaticFiles();

        app.UseSession();

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

如. asp.net core 2.0 has changed it to use the ConfigureApplicationCookie method. More info about migrating Identity to Core 2.0 here.
