c# - 状态 cookie 无效。处理远程登录时遇到错误。 ASP.NET Core MVC 外部社交登录

Question

在没有 ASP.NET Core Identity 的 ASP.NET Core2.2 MVC Web 应用程序中实现外部社交登录时。成功登录 Google、Facebook、Twitter、LinkedIn 和 Microsoft 后，我​​在重定向回应用程序时遇到以下错误。

An unhandled exception occurred while processing the request. Exception: Invalid state cookie. Unknown location

Exception: An error was encountered while handling the remote login. Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler.HandleRequestAsync()

以下是 Startup.cs 文件中的设置

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
           .AddAuthentication(options =>
           {
               options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
               options.DefaultChallengeScheme = GoogleDefaults.AuthenticationScheme;
           })
           .AddCookie(options =>
           {
               options.Cookie.IsEssential = true;
           })
           .AddGoogle(options =>
           {
               options.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
               options.ClientId = Configuration["Authentication:Google:ClientId"];
               options.ClientSecret = Configuration["Authentication:Google:ClientSecret"];
               options.CallbackPath = "/externallogincallback";             
           })
           .AddFacebook(facebookOptions =>
           {
               facebookOptions.AppId = Configuration["Authentication:Facebook:AppId"];
               facebookOptions.AppSecret = Configuration["Authentication:Facebook:AppSecret"];
               facebookOptions.CallbackPath = "/externallogincallback";                                        
           })
           .AddLinkedIn(linkedinOptions =>
           {
               linkedinOptions.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
               linkedinOptions.ClientId = Configuration["Authentication:LinkedIn:ClientId"];
               linkedinOptions.ClientSecret = Configuration["Authentication:LinkedIn:ClientSecret"];
               linkedinOptions.CallbackPath = "/externallogincallback";                    
           })
           .AddTwitter(twitterOptions =>
           {
               twitterOptions.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
               twitterOptions.ConsumerKey = Configuration["Authentication:Twitter:ConsumerKey"];
               twitterOptions.ConsumerSecret = Configuration["Authentication:Twitter:ConsumerSecret"];
               twitterOptions.CallbackPath = "/Home/externallogincallback";                    
           }).AddMicrosoftAccount(microsoftOptions =>
           {
               microsoftOptions.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
               microsoftOptions.ClientId = Configuration["Authentication:Microsoft:ClientId"];
               microsoftOptions.ClientSecret = Configuration["Authentication:Microsoft:ClientSecret"];
               microsoftOptions.CallbackPath = "/externallogincallback";
           });
       services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
   }

以下是 HomeController.cs 的详细信息(因为我没有使用 Identity，所以我需要专门定义重定向 url。)

      //Action to issue a challange to google login
        public IActionResult LogInMicrosoft(string provider)
        {
            //provider = Microsot or Google or LinkedIn or Twitter or Facebook
            provider = "Microsoft";
            //Issue a challenge to external login middleware to trigger sign in process
            //return new ChallengeResult(provider);

            var authenticationProperties = new AuthenticationProperties
            {
                RedirectUri = Url.Action("externallogincallback")
            };

            return Challenge(authenticationProperties, provider);
            //return new ChallengeResult(provider);
        }

        //Callback action to retrive signin user details
        //public IActionResult externallogincallback(string returnUrl = null, string remoteError = null)\
        public IActionResult externallogincallback()
        {
            //Here we can retrieve the claims
            // read external identity from the temporary cookie
            //var authenticateResult = HttpContext.GetOwinContext().Authentication.AuthenticateAsync("ExternalCookie");
            var result = HttpContext.AuthenticateAsync(CookieAuthenticationDefaults.AuthenticationScheme);

            if (result.Result?.Succeeded != true)
            {
                throw new Exception("External authentication error");
            }

            // retrieve claims of the external user
            var externalUser = result.Result.Principal;
            if (externalUser == null)
            {
                throw new Exception("External authentication error");
            }

            // retrieve claims of the external user
            var claims = externalUser.Claims.ToList();

            // try to determine the unique id of the external user - the most common claim type for that are the sub claim and the NameIdentifier
            // depending on the external provider, some other claim type might be used
            //var userIdClaim = claims.FirstOrDefault(x => x.Type == JwtClaimTypes.Subject);
            var userIdClaim = claims.FirstOrDefault(x => x.Type == ClaimTypes.NameIdentifier);
            if (userIdClaim == null)
            {
                throw new Exception("Unknown userid");
            }

            var externalUserId = userIdClaim.Value;
            var externalProvider = userIdClaim.Issuer;

            // use externalProvider and externalUserId to find your user, or provision a new user

            return RedirectToAction("Privacy", "Home");
        }

Answer 1

您似乎想将请求重定向到 externallogincallback登录微软账户后。如果是这样，你不应该设置 microsoftOptions.CallbackPath与 externallogincallback .使用此设置，来自 Microsoft 的所有请求都将由 OAuth 中间件处理，而不是您自己的端点 externallogincallback .

对于登录后重定向页面，您需要通过 return Challenge(authenticationProperties, provider);通过设置 authenticationProperties.authenticationProperties
请按照以下步骤操作:

更改 REDIRECT URI在 Azure 门户中使用 https://localhost:xxx/signin-microsoft

更改 Startup.cs和

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().SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

        services.AddAuthentication(options =>
            {
                options.DefaultScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                //options.DefaultChallengeScheme = GoogleDefaults.AuthenticationScheme;
            })
            .AddCookie(options =>
            {
                options.Cookie.IsEssential = true;
                //options.Cookie.SameSite = SameSiteMode.None;
            })
            .AddMicrosoftAccount(microsoftOptions =>
            {
                microsoftOptions.SignInScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                microsoftOptions.ClientId = Configuration["Authentication:Microsoft:ClientId"];
                microsoftOptions.ClientSecret = Configuration["Authentication:Microsoft:ClientSecret"];                    
            });
    }

    // 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");
            // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
            app.UseHsts();
        }

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

家庭 Controller

    }

    [Route("/[action]")]
    public async Task<IActionResult> externallogincallback()

        var request = HttpContext.Request;
        //Here we can retrieve the claims
        // read external identity from the temporary cookie
        //var authenticateResult = HttpContext.GetOwinContext().Authentication.AuthenticateAsync("ExternalCookie");
        var result = await HttpContext.AuthenticateAsync(CookieAuthenticationDefaults.AuthenticationScheme);

        if (result.Succeeded != true)
        {
            throw new Exception("External authentication error");
        }

        // retrieve claims of the external user
        var externalUser = result.Principal;
        if (externalUser == null)
        {

        }

        // retrieve claims of the external user
        var claims = externalUser.Claims.ToList();

        // try to determine the unique id of the external user - the most common claim type for that are the sub claim and the NameIdentifier

        }

        var externalUserId = userIdClaim.Value;
        var externalProvider = userIdClaim.Issuer;
