我一直致力于将单体 ASP Core MVC 应用程序迁移到使用服务架构设计。 MVC 前端网站使用 HttpClient 从 ASP Core Web API 加载必要的数据。一小部分前端 MVC 应用程序还需要使用 IdentityServer4(与后端 API 集成)进行身份验证。这一切都很好，直到我将 Authorize 属性放在 Web API 的 Controller 或方法上。我知道我需要以某种方式将用户授权从前端传递到后端才能使其正常工作，但我不确定如何进行。我尝试获取 access_token:User.FindFirst("access_token") 但它返回 null。然后我尝试了这个方法，我能够得到 token :

var client = new HttpClient("url.com");
var token = HttpContext.Authentication.GetTokenAsync("access_token")?.Result;
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", token);

此方法获取 token 但仍未通过后端 API 进行身份验证。我对这个 OpenId/IdentityServer 概念还很陌生，如有任何帮助，我将不胜感激!

下面是 MVC Client Startup 类的相关代码:

    private void ConfigureAuthentication(IApplicationBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationScheme = "Cookies",
            AutomaticAuthenticate = true,
            ExpireTimeSpan = TimeSpan.FromMinutes(60)
        });
        JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();
        app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
        {
            AuthenticationScheme = "oidc",
            SignInScheme = "Cookies",

            Authority = "https://localhost:44348/",
            RequireHttpsMetadata = false,

            ClientId = "clientid",
            ClientSecret = "secret",

            ResponseType = "code id_token",
            Scope = { "openid", "profile" },
            GetClaimsFromUserInfoEndpoint = true,
            AutomaticChallenge = true, // Required to 302 redirect to login
            SaveTokens = true,

            TokenValidationParameters = new Microsoft.IdentityModel.Tokens.TokenValidationParameters
            {
                NameClaimType = "Name",
                RoleClaimType = "Role",
                SaveSigninToken = true
            },


        });
    }

和 API 的 StartUp 类:

        // Add authentication
        services.AddIdentity<ExtranetUser, IdentityRole>(options =>
        {
            // Password settings
            options.Password.RequireDigit = true;
            options.Password.RequiredLength = 8;
            options.Password.RequireNonAlphanumeric = true;
            options.Password.RequireUppercase = true;
            options.Password.RequireLowercase = true;

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

            // User settings
            options.User.RequireUniqueEmail = true;
        })
            .AddDefaultTokenProviders();
        services.AddScoped<IUserStore<ExtranetUser>, ExtranetUserStore>();
        services.AddScoped<IRoleStore<IdentityRole>, ExtranetRoleStore>();
        services.AddSingleton<IAuthorizationHandler, AllRolesRequirement.Handler>();
        services.AddSingleton<IAuthorizationHandler, OneRoleRequirement.Handler>();
        services.AddSingleton<IAuthorizationHandler, EditQuestionAuthorizationHandler>();
        services.AddSingleton<IAuthorizationHandler, EditExamAuthorizationHandler>();
        services.AddAuthorization(options =>
        {
            /* ... etc .... */
        });
        var serviceProvider = services.BuildServiceProvider();
        var serviceSettings = serviceProvider.GetService<IOptions<ServiceSettings>>().Value;
        services.AddIdentityServer() // Configures OAuth/IdentityServer framework
            .AddInMemoryIdentityResources(IdentityServerConfig.GetIdentityResources())
            .AddInMemoryClients(IdentityServerConfig.GetClients(serviceSettings))
            .AddAspNetIdentity<ExtranetUser>()
            .AddTemporarySigningCredential(); // ToDo: Add permanent SigningCredential for IdentityServer

最佳答案

添加了 nuget package here以及以下修复代码:

app.UseIdentityServerAuthentication(new IdentityServerAuthenticationOptions
{
   Authority = "https://localhost:44348/",
   ApiName = "api"
});

这允许 API 托管 IdentityServer4 并将其自身用作身份验证。然后在 MvcClient 中，不记名 token 可以传递给 API。
