在 Blazor wasm 中自动将身份 Cookie 附加到 HTTP 客户端

Question

我正在开发一个 blazor 应用程序，其中我使用我的 API 项目作为身份

提供者。 一切正常，但问题是访问令牌

我的 API 发布的 API 未经过验证。 事实证明，API 期待一个

饼干头。 我仔细查看了 blazor 托管应用程序并发现

cookie 与每个请求一起发送，但它是同源的。

我的 Blazor WASM 项目不会在请求中自动附加此 cookie

标头，只是访问令牌。

有没有办法让 Http 处理程序在每个请求上附加这个 cookie？

或者让 API 验证访问令牌而不是身份 cookie。

这是我在 API 项目中的启动类

       public static void AddIdentityServer(IServiceCollection services,IConfiguration configuration)
        {
            services.AddIdentityServer(options =>
            {
                options.UserInteraction.LoginUrl = "/Identity/Account/Login";
                options.UserInteraction.LogoutUrl = "/Identity/Account/Logout";
            }).AddProfileService<LocalProfileService>()
             .AddApiAuthorization<ApplicationUser, ApplicationDbContext>(option =>
             {
                 option.Clients.Add(new Client
                 {
                     ClientId = "blazor",
                     AllowedGrantTypes = GrantTypes.Code,
                     RequirePkce = true,
                     RequireClientSecret = false,
                     AllowedCorsOrigins = { "https://localhost:5001" },
                     AllowedScopes = { "openid", "profile", "email","id" },
                     RedirectUris = { "https://localhost:5001/authentication/login-callback" },
                     PostLogoutRedirectUris = { "https://localhost:5001/" },
                     Enabled = true,
                     RequireConsent = false,  
                 });
                 option.IdentityResources.AddEmail();
                 option.IdentityResources["openid"].UserClaims.Add("name");
                 option.ApiResources.Single().UserClaims.Add("name");
                 option.IdentityResources["openid"].UserClaims.Add("role");
                 option.ApiResources.Single().UserClaims.Add("role");

                 option.IdentityResources.Add(new IdentityResource("id",new string[] {"id" }));
                 option.ApiResources.Single().UserClaims.Add("id");
                 

             });

            services.AddAuthentication()
                .AddGoogle("Google", options =>
                {
                    options.ClientId = configuration["ExternalLoginApiKey:GoogleClientId"];
                    options.ClientSecret = configuration["ExternalLoginApiKey:GoogleClientSecret"];
                })
                .AddFacebook("Facebook", options =>
                {
                    options.AppId = configuration["ExternalLoginApiKey:FacebookAppId"];
                    options.AppSecret = configuration["ExternalLoginApiKey:FacebookAppSecret"];
                })
               .AddIdentityServerJwt();

          
        }

Blazor 项目中的程序类

        public static async Task Main(string[] args)
        {
            var builder = WebAssemblyHostBuilder.CreateDefault(args);
            builder.RootComponents.Add<App>("app");

            builder.Services.AddOidcAuthentication(options =>
            {
                builder.Configuration.Bind("oidc", options.ProviderOptions);
                options.UserOptions.RoleClaim = "role";
            }).AddAccountClaimsPrincipalFactory<CustomUserFactory>();

            builder.Services.AddHttpClient<IAuthorizedRestService, AuthorizedRestService>(
               client => client.BaseAddress = new Uri("https://localhost:5002/api/mart/v1/"))
                 .AddHttpMessageHandler(sp => sp.GetRequiredService<AuthorizationMessageHandler>()
            .ConfigureHandler(authorizedUrls: new[] { "https://localhost:5002" }));


            builder.Services.AddHttpClient("noauth", option => option.BaseAddress = new 
              Uri("https://localhost:5002/api/mart/v1/"));

            builder.Services.AddScoped<IRestService, RestService>();

            await builder.Build().RunAsync();
        }

Answer 1

我找到了解决方案。

碰巧 IdentityServer4 已经为 API 提供了一个 JWT 处理程序，可以兼作授权服务器

 .AddIdentityServerJwt();

所以我所做的是配置它

      services.Configure<JwtBearerOptions> 
       (IdentityServerJwtConstants.IdentityServerJwtBearerScheme,
                options =>
                {
                    options.Authority = "https://localhost:5002";
                    options.Audience = "mart";
                    options.SaveToken = true;
                });

然后指定要使用的身份验证方案

    [Authorize(AuthenticationSchemes = IdentityServerJwtConstants.IdentityServerJwtBearerScheme)]

也可以在启动类中全局添加

 var authorizationPolicy = new AuthorizationPolicyBuilder(IdentityServerJwtConstants.IdentityServerJwtBearerScheme)
                .RequireAuthenticatedUser().Build();
                options.Filters.Add(new AuthorizeFilter(authorizationPolicy));
