通过带有 AzureAd 的 Asp.Net Core 2.2 访问“employeeId”或“jobTitle”声明

Question

我正在尝试扩展我从 AzureAd 收到的声明。我知道还有更多可用的，但我不知道从哪里开始。文档到处都是。

我基本上有一个 ASP .Net Core 2.2 Web 应用程序配置如下：

            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(AzureADDefaults.AuthenticationScheme)
                .AddAzureAD(options => Configuration.Bind("AzureAd", options));

            services.AddMvc(options =>
            {
                var policy = new AuthorizationPolicyBuilder()
                    .RequireAuthenticatedUser()
                    .Build();
                options.Filters.Add(new AuthorizeFilter(policy));
            })
            .SetCompatibilityVersion(CompatibilityVersion.Version_2_2);

当尝试通过下面的代码访问声明时，我没有得到标准声明，而 AzureAd 和 Graph 中加载了更多声明。

            var claimsIdentity = User.Identity as ClaimsIdentity;
            ClaimsDetected = claimsIdentity?.Claims.ToList();   

我已经使用各种选项调整了清单文件，但似乎没有任何效果。我在 Google 上搜索了我的 *ss，但所有文档都已过期，并且不一致或已过时。

有没有人可以使用示例或教程，或者谁能告诉我如何使用我在图中找到的特定类型来丰富我的声明集？

谢谢

要从 Azure AD 访问 jobTitle 到 Claims，您需要获取访问令牌才能通过 Graph API 获取 jobTitle。

详细步骤。

1. 获取accesstoken需要在Azure中提供ClientSecretApp registrations
2. App Registrations->Your application->Settings->Keys->ClientSecret or any string for Key Description->Expires for your own scenario->复制生成的ClientSecret

3. 启动.cs

   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(AzureADDefaults.AuthenticationScheme)
           .AddAzureAD(options => Configuration.Bind("AzureAd", options));
       services.Configure<OpenIdConnectOptions>(AzureADDefaults.OpenIdScheme, options =>
       {
           options.ResponseType = "id_token code";
           options.ClientSecret = "ClientSecret in Azure";
           options.Events = new OpenIdConnectEvents
           {
               OnAuthorizationCodeReceived = async context => {
                   // Acquire a Token for the Graph API and cache it using ADAL. In the TodoListController, we'll use the cache to acquire a token for the Todo List API
                   string userObjectId = (context.Principal.FindFirst("http://schemas.microsoft.com/identity/claims/objectidentifier"))?.Value;
                   var authContext = new AuthenticationContext(context.Options.Authority);
                   var credential = new ClientCredential(context.Options.ClientId, context.Options.ClientSecret);
   
                   var authResult = await authContext.AcquireTokenByAuthorizationCodeAsync(context.TokenEndpointRequest.Code,
                       new Uri(context.TokenEndpointRequest.RedirectUri, UriKind.RelativeOrAbsolute), credential, "https://graph.microsoft.com");
   
                   // Notify the OIDC middleware that we already took care of code redemption.
                   context.HandleCodeRedemption(authResult.AccessToken, context.ProtocolMessage.IdToken);
                   HttpClient client = new HttpClient();
                   HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get, "https://graph.microsoft.com/v1.0/me");
                   request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
                   HttpResponseMessage response = await client.SendAsync(request);
                   var result = await response.Content.ReadAsStringAsync();
                   // Parse your Result to an Array
                   var jArray = JObject.Parse(result);
                   // Index the Array and select your jobTitle
                   var obj = jArray["jobTitle"].Value<string>();
                   var identity = context.Principal.Identity as ClaimsIdentity;
                   identity.AddClaim(new Claim("jobTitle", obj));
                   await Task.Yield();
               },
           };
       });
       services.AddMvc(options =>
       {
           var policy = new AuthorizationPolicyBuilder()
               .RequireAuthenticatedUser()
               .Build();
           options.Filters.Add(new AuthorizeFilter(policy));
       })
       .SetCompatibilityVersion(CompatibilityVersion.Version_2_2);
   }
