Question

我在之前正在运行的应用程序中使用RC更新了ASP.NET 5框架beta-8软件包。在我运行后，在启动过程中发生了下一个错误：

InvalidOperationException：没有配置身份验证处理程序来处理该方案：自动 Microsoft.AspNet.Http.Authentication.Internal.DefaultAuthenticationManager.d__12.MoveNext（）

var defaultPolicy =
    new AuthorizationPolicyBuilder()
    .RequireAuthenticatedUser()
    .Build();

services.AddMvc(setup =>
{
    setup.Filters.Add(new AuthorizeFilter(defaultPolicy)); // Error occurs here
});

如果有人有类似的问题，我会感谢您对可能出错的想法或解决方案。此异常的解释也很受欢迎。

Answer 1

希望这会对其他人有所帮助，因为我花了很多时间来处理这个错误，即使我设置了AutomaticChallenge = true。

如果您将app.UseIdentity();放在app.UseMvc(routes => ...)之后，则会出现同样的错误。现在我知道答案很明显了。这是因为所有这些中间件都按照您添加它的顺序发生。

这会导致＆＃34; 没有配置身份验证处理程序＆＃34;错误：

    public void Configure(...)
    {
        app.UseMvc(routes => { routes.MapRoute(...) }; );

        app.UseIdentity();
    }

这不会导致错误：

    public void Configure(...)
    {
        app.UseIdentity();

        app.UseMvc(routes => { routes.MapRoute(...); });
    }

Answer 2

尝试在Cookie选项中设置options.AutomaticChallenge = true;，它应该有效。

options.AutomaticAuthentication分为options.AutomaticAuthenticate和options.AutomaticChallenge。如果最后一个留给false，则抛出异常，因为没有身份验证中间件处理授权过滤器应用的质询。

Answer 3

将其放在Configure方法上。

        app.UseIdentity();

Answer 4

通过确保cookie方案在引用的任何地方始终被命名，我解决了这个问题。 e.g：

public void ConfigureServices(IServiceCollection services)
{
    // if using IdentityServer4
    var builder = services.AddIdentityServer(options =>
    {
        options.AuthenticationOptions.AuthenticationScheme = Constants.DefaultCookieAuthenticationScheme;
        ...
    })

    services.AddIdentity<MyUser, IdentityRole>(options =>
    {
        options.Cookies.ApplicationCookie.AuthenticationScheme = Constants.DefaultCookieAuthenticationScheme;
        ...
    }
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    ...
    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationScheme = Constants.DefaultCookieAuthenticationScheme,
        AutomaticAuthenticate = false,
        AutomaticChallenge = true
    });
}

与身份验证中间件交互时。 e.g：

await HttpContext.Authentication.SignInAsync(Constants.DefaultCookieAuthenticationScheme, cp);

Answer 5

如果您使用app.UseIdentity();和其他一些登录中间件，例如UseFacebookAuthentication，请确保app.UseFacebookAuthentication()在app.UseIdentity();之后。

Answer 6

另一种可能性是在配置

中缺少以下设置

app.UseCookieAuthentication();

Answer 7

虽然很有可能将我们的大部分配置设置放在startup.cs文件中，但似乎首选的方法是设置app.UseCookieAuthentication() - sans选项 - startup.cs文件，然后放置所有＆＃39;选项＆＃39;和单独文件中的其他细节。

类似于我们在处理Global.asax文件如何指向Asp.Net vBefore中App_Start文件夹文件的方式。

尝试在startup.cs中配置EF / Sql时，我遇到了类似的痛苦，并且移动了所有选项＆＃39;在startup.cs之外，事情变得更好。

另外：请注意Fredy Wenger对您的问题的评论，该评论指出了重命名＆＃39;从v -8beta到v -RC1-final的许多名称空间。
