MVC [Authorize] 属性适用于除主页之外的每个页面

Question

我在 .Net Core 2.1 Web 应用程序中使用 cookie 身份验证，我似乎无法让 authorize 属性在默认主页（webapp url）上工作。该属性适用于所有其他页面。

当我转到 https://appurl/home 时，它会重定向到登录，但导航到 https://appurl 根本不需要身份验证。这是我的启动路由：

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

这是我的家庭控制器：

[Authorize]
public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }

    [ResponseCache(Duration = 0, Location = ResponseCacheLocation.None, NoStore = true)]
    public IActionResult Error()
    {
        return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
    }
}

所有其他标有 [Authorize] 的控制器都像这样重定向到按预期登录，我只是不知道如何在默认应用程序 url 上指定授权。

任何帮助将不胜感激。

更新：我想我已经解决了我的问题，基本上默认情况下需要 auth 并允许匿名访问我的登录 razor 页面（我同时使用 mvc 和 razor 页面）。我仍然很好奇它是否可以通过其他方式完成，但这是我的 startup.cs：

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

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {
        /*
        services.Configure<CookiePolicyOptions>(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });
        */

        services.AddMvc(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new AuthorizeFilter(policy));
            })
            .AddRazorPagesOptions(options =>
            {
                options.Conventions.AllowAnonymousToPage("/Account/Login");
            })
            .SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

        services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
            .AddCookie(options =>
            {
                options.LoginPath = "/Account/Login";
                options.LogoutPath = "/Account/Logout";
            });

        // Add DB contexts here.
        services.Configure<Database.DatabaseConfig>(Configuration.GetSection("ConnectionStrings"));

        services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
    }

    // 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();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
            app.UseHsts();
        }

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

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

你好像忘了在services.AddAuthentication (...);下面添加services.AddAuthorization ();

如果你这样做，可能你就不需要这个了：

services.AddMvc(options =>
{
    var policy = new AuthorizationPolicyBuilder()
        .RequireAuthenticatedUser()
        .Build();
    options.Filters.Add(new AuthorizeFilter(policy));
})
.AddRazorPagesOptions(options =>
{
    options.Conventions.AllowAnonymousToPage("/Account/Login");
})
.SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

您可以为此进行更改：

services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
