我正在运行ASP.NET MVC 6的RC1版本，并希望使用MongoDB身份验证提供程序。
我已经实现了Grant Megrabyan的提供程序，它很好地注册了新用户并允许他们登录，但我遇到了以下错误：
InvalidOperationException：未配置身份验证处理程序以处理方案：Microsoft.AspNet.Identity.External Microsoft.AspNet.Http.Authentication.Internal.DefaultAuthenticationManager.d__13.MoveNext（）
我之前已经使用EntityFramework使外部登录正常工作，因此我认为我的第三方身份验证配置可能是正确的。
当用户点击“使用Facebook登录”时，他们将被重定向到以下操作：
// POST: /Account/ExternalLogin
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public IActionResult ExternalLogin(string provider, string returnUrl = null)
{
// Request a redirect to the external login provider.
var redirectUrl = Url.Action("ExternalLoginCallback", "Account", new { ReturnUrl = returnUrl });
var properties = _signInManager.ConfigureExternalAuthenticationProperties(provider, redirectUrl);
return new ChallengeResult(provider, properties);
}
在这一点上没有抛出任何异常，但是当Facebook从ChallengeResponse返回时，它会发送一个GET到: http://localhost:51265/signin-facebook?code=[facebook user token]。
此时，ASP.NET会抛出异常：
Facebook生成的回调URL似乎没有意义。它应该返回到我的ExternalLoginCallback操作，是吗？
在这里，我已经没有更多的想法了？！
如果有人看出了我的错误，那我会非常高兴。
我的startup.cs：
public class Startup
{
public Startup(IHostingEnvironment env)
{
// Set up configuration sources.
var builder = new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true);
if (env.IsDevelopment())
{
// For more details on using the user secret store see http://go.microsoft.com/fwlink/?LinkID=532709
builder.AddUserSecrets();
}
builder.AddEnvironmentVariables();
Configuration = builder.Build();
}
public IConfigurationRoot Configuration { get; set; }
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.AddSingleton<ApplicationDbContext>();
// Add framework services.
services.AddIdentity<ApplicationUser, IdentityRole>()

services.AddMvc();
// Add application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
loggerFactory.AddConsole(Configuration.GetSection("Logging"));
loggerFactory.AddDebug();
if (env.IsDevelopment())

app.UseBrowserLink();
app.UseDeveloperExceptionPage();
app.UseDatabaseErrorPage();
}
else
{
app.UseExceptionHandler("/Home/Error");
}
app.UseIISPlatformHandler(options => options.AuthenticationDescriptions.Clear());
app.UseStaticFiles();
app.UseFacebookAuthentication(options =>

});
app.UseIdentity();

}
// Entry point for the application.
public static void Main(string[] args) => WebApplication.Run<Startup>(args);
