Asp.Net MVC 6身份3 MongoDB外部登录(Facebook)

Question

我正在运行ASP.NET MVC 6的RC1,并希望使用MongoDB身份提供程序.

我已经实现了Grant Megrabyan 的提供程序,它正在很好地注册新用户并允许他们登录但我得到错误:

InvalidOperationException:没有配置身份验证处理程序来处理该方案:Microsoft.AspNet.Identity.External Microsoft.AspNet.Http.Authentication.Internal.DefaultAuthenticationManager.d__13.MoveNext()

我之前使用EntityFramework进行了外部登录,所以我假设我的第三方auth配置可能是正确的.

当用户点击登录Facebook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);
    }

此时没有异常抛出,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抛出异常:

Facebook制作的回调网址似乎没有意义.当然应该返回我的ExternalLoginCallback操作？

这是关于我的想法？!

如果有人能看到我出错的地方那么我就是一个非常快乐的人.

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>()
            .AddMongoStores<ApplicationDbContext, ApplicationUser, IdentityRole>()
            .AddDefaultTokenProviders();

        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 =>
        {
            options.AppId = "removed";
            options.AppSecret = "removed";
        });

        app.UseIdentity();

        app.UseMvcWithDefaultRoute();
    }

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

Answer 1

打电话UseFacebookAuthentication之后UseIdentity,但之前UseMvc;

app.UseIdentity();

app.UseFacebookAuthentication(options =>
{
    options.AppId = "removed";
    options.AppSecret = "removed";
});

app.UseMvcWithDefaultRoute();
