从职位描述属性中获取员工 ID .NET 8

Question

我正在尝试从 Azure EntraId 获取员工 ID 字段。有关此处显示的问题的更多详细信息：

在此屏幕截图中，您可以看到我尝试使用 MS Graph 客户端获取的

employee id

字段，但每次尝试时我都得到 null：

这是我用于通过图形客户端获取数据的代码：

private static GraphServiceClient GetGraphClient(string clientId, string tenantId, string clientSecret)
{
    // Set up the client credential authentication provider
    var confidentialClientApplication = ConfidentialClientApplicationBuilder.Create(clientId)
            .WithClientSecret(clientSecret)
            .WithAuthority(new Uri($"https://login.microsoftonline.com/{tenantId}"))
            .Build();

    var authProvider = new ClientSecretCredential(tenantId, clientId, clientSecret);

    // Create and return the GraphServiceClient with the authentication provider
    return new GraphServiceClient(authProvider);
}

这是获取员工的代码：

var result = await graphClient.Users
                        .GetAsync((requestConfiguration) =>
                            {
                               requestConfiguration.QueryParameters.Filter = $"displayname eq '{User.Mail}'";
                               requestConfiguration.QueryParameters.Select = ["employeeId", "EmployeeID", "EMP_ID"];
                            });

我正在从索赔中获取所有其他基本详细信息。

请帮我也拿

employee id

。

Answer 1

最初注册单租户 Microsoft Entra ID 应用程序，添加并授予应用程序类型

User.Read.All

API 权限：

我创建了一个测试用户作为

testUser1

并配置了

employeeId

和

mail

。

在 Portal 中，确保属性中的

Employee ID

不应该为 null，并且应该存在，如下所示：

使用下面修改后的代码，要获取特定用户的

employee_ID

：

using Microsoft.Graph;
using Azure.Identity; // For ClientSecretCredential
using System;
using System.Threading.Tasks;

public class GraphClientExample
{
    private static GraphServiceClient GetGraphClient(string clientId, string tenantId, string clientSecret)
    {
        // Use ClientSecretCredential for authentication
        var clientSecretCredential = new ClientSecretCredential(tenantId, clientId, clientSecret);

        // Return the GraphServiceClient using ClientSecretCredential
        return new GraphServiceClient(clientSecretCredential);
    }

    public static async Task FetchEmployee(string clientId, string tenantId, string clientSecret, string userMail)
    {
        if (string.IsNullOrEmpty(userMail))
        {
            Console.WriteLine("User mail is null or empty.");
            return;
        }

        // Initialize Graph client
        var graphClient = GetGraphClient(clientId, tenantId, clientSecret);

        try
        {
            // Fetch the user details
            var result = await graphClient.Users
                .GetAsync((requestConfiguration) =>
                {
                    // Apply filter and select query
                    requestConfiguration.QueryParameters.Filter = $"mail eq '{userMail}'";
                    requestConfiguration.QueryParameters.Select = new[] { "id", "displayName", "mail", "employeeId" };
                });

            // Check if any users are found
            if (result?.Value != null && result.Value.Count > 0)
            {
                foreach (var user in result.Value)
                {
                    Console.WriteLine($"User Found: {user.DisplayName}, ID:{user.Id}, Email: {user.Mail}, Employee ID: { user.EmployeeId}");
                }
            }
            else
            {
                Console.WriteLine("No matching user found.");
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine($"An error occurred: {ex.Message}");
        }
    }

    public static async Task Main(string[] args)
    {
        // Replace these with your app registration details
        string clientId = "<YOUR CLIENT ID";
        string tenantId = "YOUR TENANAT ID";
        string clientSecret = "YOUR CLIENT SECRET";
        string userMail = "<YOUR TEST USER EMAIL SEARCH>"; // Email to search

        await FetchEmployee(clientId, tenantId, clientSecret, userMail);
    }
}
