c# - ASP.NET 核心 2.0 : Authorization failed for user: (null)

Question

我正在构建一个应用程序，其中 Web API 和 IdentityServer4 位于同一个 .Net Core 2.0 项目中。此 API 由 Aurelia SPA 网络应用程序使用。 IdentityServer4 设置为使用 JWT 和 ImplicitFlow。一切正常(客户端应用程序被重定向到登录、获取 token 、将其发送回 header 等)直到用户需要在 API Controller 中获得授权，然后它就无法授权用户，因为它是空的。

存在许多类似的问题，但我尝试了所有建议的解决方案，但没有一个对我有用。我已经在这个问题上花了 2 天时间，开始失去希望和耐心。我可能遗漏了一些明显的东西，但就是找不到。我在这里发布我的配置 - 它们有什么问题？将不胜感激。

我的 Startup 类(我省略了一些额外的东西，比如日志记录、本地化等):

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddDbContext<ApplicationDbContext>(options =>
            options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

        services.AddIdentity<ApplicationUser, IdentityRole>()
            .AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

        services.AddCors(options =>
        {
            options.AddPolicy("default", policy =>
            {
                policy.WithOrigins(Config.APP1_URL)
                    .AllowAnyHeader()
                    .AllowAnyMethod();
            });
        });

        services.AddMvc();

        services.Configure<IdentityOptions>(options =>
        {
            // Password settings
            options.Password.RequireDigit = false;
            options.Password.RequiredLength = 8;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireUppercase = false;
            options.Password.RequireLowercase = false;
            options.Password.RequiredUniqueChars = 4;

            // Lockout settings
            options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
            options.Lockout.MaxFailedAccessAttempts = 10;
            options.Lockout.AllowedForNewUsers = true;

            // User settings
            options.User.RequireUniqueEmail = true;
        });

        services.AddIdentityServer()
            .AddDeveloperSigningCredential()
            .AddInMemoryPersistedGrants()
            .AddInMemoryIdentityResources(Config.GetIdentityResources())
            .AddInMemoryApiResources(Config.GetApiResources())
            .AddInMemoryClients(Config.GetClients())
            .AddAspNetIdentity<ApplicationUser>();

        services.AddAuthentication(IdentityServerAuthenticationDefaults.AuthenticationScheme)
            .AddIdentityServerAuthentication(options =>
            {
                options.Authority = Config.HOST_URL + "/";
                options.RequireHttpsMetadata = false;
                options.ApiName = "api1";
            });
    }

    public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
            app.UseBrowserLink();
            app.UseDatabaseErrorPage();
        }
        else
        {
            app.UseExceptionHandler("/Home/Error");
        }

        app.UseStaticFiles();

        app.UseIdentityServer();

        app.UseAuthentication();

        app.UseCors("default");

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

这是我的配置类:

public class Config
{
    public static string HOST_URL = "http://dev.example.com:5000";
    public static string APP1_URL = "http://dev.example.com:9000";

    public static IEnumerable<IdentityResource> GetIdentityResources()
    {
        return new List<IdentityResource>
        {
            new IdentityResources.OpenId(),
            new IdentityResources.Profile()
        };
    }

    public static IEnumerable<ApiResource> GetApiResources()
    {
        return new List<ApiResource>
        {
            new ApiResource("api1", "My API")
        };
    }

    public static IEnumerable<Client> GetClients()
    {
        return new List<Client>
        {
            new Client
            {
                ClientId = "reporter",
                ClientName = "ReporterApp Client",
                AccessTokenType = AccessTokenType.Jwt,
                AllowedGrantTypes = GrantTypes.Implicit,
                RequireConsent = false,
                AllowAccessTokensViaBrowser = true,
                RedirectUris =
                {
                    $"{APP1_URL}/signin-oidc"
                },
                PostLogoutRedirectUris = {
                    $"{APP1_URL}/signout-oidc"
                },
                AllowedCorsOrigins = {
                    APP1_URL
                },

                AllowedScopes =
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    "api1"
                }
            }
        };
    }
}

Aurelia 应用程序从 IdentityServer 获取 token :

{
    "alg": "RS256",
    "kid": "52155e28d23ddbab6154ce0c34511c9a",
    "typ": "JWT"
},
{
    "nbf": 1521195164,
    "exp": 1521198764,
    "iss": "http://dev.example.com:5000",
    "aud": ["http://dev.example.com:5000/resources", "api1"],
    "client_id": "reporter",
    "sub": "767381df-446a-4c34-af27-7bdf9e4563f3",
    "auth_time": 1521195163,
    "idp": "local",
    "scope": ["openid", "profile", "api1"],
    "amr": ["pwd"]
}

Answer 1

首先，交换您的订单 UseAuthencation 而不是写一些东西。

app.UseAuthentication();
app.UseIdentityServer();

其次更改 cookie 方案。 Identityserver4 有自己的，所以你的用户是空的，因为它没有读取 cookie。

services.AddAuthentication(IdentityServerConstants.DefaultCookieAuthenticationScheme)
                .AddIdentityServerAuthentication(options =>
                {
                    // base-address of your identityserver
                    options.Authority = Configuration.GetSection("Settings").GetValue<string>("Authority");
                    // name of the API resource
                    options.ApiName = "testapi";
                    options.RequireHttpsMetadata = false;
                }); 

想法三:

我必须将类型添加到 api 调用中，以便它读取不记名 token 。

[HttpPost("changefiscal")]
[Authorize(AuthenticationSchemes = "Bearer")]
public async Task<ActionResult> ChangeFiscal([FromBody] long fiscalId)
  {
   // STuff here
   }
