.NET 8.0 控制台应用程序使用 PnP Core SDK 连接到 SharePoint Online，我的操作正确吗？

Question

我想创建一个使用 PnP 核心 SDK 连接到 SharePoint 在线租户的 .net 8.0 控制台应用程序。现在我没有找到任何示例代码，所以我开发了这个控制台应用程序：-

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using PnP.Core.Auth;
using PnP.Core.Model.SharePoint;
using PnP.Core.Services;
using PnP.Core.Services.Builder.Configuration;
using System;
using System.Security.Cryptography.X509Certificates;

namespace ConsoleApp4
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            var tenantId = "**c";
            var clientId = "7***9";
            var certificatePath = @"c:\CERT\SPDashBoard.pfx";
            var certificatePassword = "******";

            // Initialize a new service collection
            var serviceCollection = new ServiceCollection();

            // Load the certificate
            var certificate = new X509Certificate2(certificatePath, certificatePassword, X509KeyStorageFlags.Exportable);

            // Configure logging
            //serviceCollection.AddLogging(builder =>
            //{
            //    builder.AddConsole();
            //});

            // Add and configure PnP Core SDK
            serviceCollection.AddPnPCore(options =>
            {
                options.PnPContext.GraphFirst = false; // Set true if you prefer to use Graph over CSOM when possible
               // options.HttpRequests.UserAgent = "ISV|Contoso|ProductX";
                options.Sites.Add("SiteToWorkWith", new PnPCoreSiteOptions
                {
                    SiteUrl = "https://seagullssms.sharepoint.com/sites/Seagulls-PPM",
                    AuthenticationProvider = new X509CertificateAuthenticationProvider(clientId, tenantId, certificate)
                });
            });

            // Build the service provider
            var serviceProvider = serviceCollection.BuildServiceProvider();

            // Use the service provider to get the IPnPContextFactory instance
            var pnpContextFactory = serviceProvider.GetRequiredService<IPnPContextFactory>();

            // Now you can use the IPnPContextFactory to get a PnPContext and perform operations
            var context = await pnpContextFactory.CreateAsync("SiteToWorkWith");

            // Example operation: Print the title of the SharePoint site
            // Explicitly load the Title property of the Web
             await context.Web.LoadAsync(w => w.Title);

            Console.WriteLine($"Site title: {context.Web.Title}");

            // Ensure to dispose the context
            context.Dispose();
        }
    }
}

我使用自签名证书在 Active Directory 中创建了应用程序注册，并将证书安装在托管服务器内。似乎上述方法有效，我能够获得网页标题..但我不确定我的方法是否有效或可以改进？

.NET 8.0 控制台应用程序使用 PnP Core SDK 在线连接到 SharePoint，我的操作是否正确？

是的，您走在正确的道路上。您还可以向代码添加错误处理，以处理身份验证过程中或从 SharePoint 检索数据时可能发生的任何异常。

或者，您还可以使用以下示例代码，利用 Microsoft Graph API 调用在线访问 SharePoint：

创建 Azure AD 应用程序并添加所需的 API 权限：

这里我尝试列出SharePoint网站名称

using Microsoft.Identity.Client;
using Newtonsoft.Json.Linq;
using System.Net.Http.Headers;


namespace ConsoleApp1
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // Set the values for your application
            string clientId = "ClientID";
            string clientSecret = "ClientSecret";
            string tenantId = "TenantID";
            string[] scopes = new string[] { "https://graph.microsoft.com/.default" };

            try
            {
                
                IConfidentialClientApplication app = ConfidentialClientApplicationBuilder
                    .Create(clientId)
                    .WithClientSecret(clientSecret)
                    .WithAuthority(new Uri($"https://login.microsoftonline.com/{tenantId}"))
                    .Build();

                // Acquire an access token for the client
                AuthenticationResult result = await app.AcquireTokenForClient(scopes)
                    .ExecuteAsync();

                string accessToken = result.AccessToken;

                using (var httpClient = new HttpClient())
                {
                    httpClient.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", accessToken);

                    var response = await httpClient.GetAsync("https://graph.microsoft.com/v1.0/sites?search=*");

                    if (response.IsSuccessStatusCode)
                    {
                        string content = await response.Content.ReadAsStringAsync();

                        // Deserialize the JSON response
                        JObject json = JObject.Parse(content);

                        // Extract the value of the "name" property for each site
                        foreach (var site in json["value"])
                        {
                            Console.WriteLine(site["name"]);
                        }
                    }
                    else
                    {
                        Console.WriteLine($"Failed to call Microsoft Graph API: {response.ReasonPhrase}");
                    }
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"An error occurred: {ex.Message}");
            }
        }
    }
}
