尝试使用 CSOM 连接到 SharePoint 时出错

Question

我目前正在尝试通过 C# 连接到我的 Microsoft SharePoint 网站。我正在使用 microsoft.sharepoint.client.online.csom .0.4919.1000 库，我没有成功...... 你能帮我吗？

我制作了一个小型控制台应用程序来测试，这是我测试的代码。

static async void CheckConnection()
{
    var passTask = GetUserPasswordAsync();
    string userID = <username>;

    using (ClientContext ctx = new ClientContext("https://<company_sharepoint>.sharepoint.com/sites/<my_site>"))
    {
        await passTask;
        if (passTask.Result is null)
            return;
        SharePointOnlineCredentials credentials = new SharePointOnlineCredentials(userID, passTask.Result);
        ctx.Credentials = credentials;
        Web myWeb = ctx.Web;
        ctx.Load(myWeb, w => w.Title);
        ctx.ExecuteQuery();
        await Console.Out.WriteLineAsync(myWeb.Title);
    }
}

但是每当我运行这行代码时

ctx.ExecuteQuery();

它抛出错误

Microsoft.SharePoint.Client.IdcrlException: 'Identity Client Runtime Library (IDCRL) did not get a response from the Login server.'

我不知道到底发生了什么，也不知道我是否使用了正确的库或方法...... 有人可以帮助我吗？

可以参考以下代码

using Microsoft.SharePoint.Client;
using System;

class Program
{
    static void Main(string[] args)
    {
        string siteUrl = "https://your-sharepoint-site-url.sharepoint.com/sites/yoursite";
        string username = "[email protected]";
        string password = "your_password";

        using (ClientContext ctx = new ClientContext(siteUrl))
        {
            // Online credentials
            ctx.Credentials = new SharePointOnlineCredentials(username, ConvertToSecureString(password));

            // Load the web
            Web web = ctx.Web;
            ctx.Load(web);
            ctx.ExecuteQuery();

            // Print some information about the web
            Console.WriteLine($"Title: {web.Title}");
            Console.WriteLine($"Description: {web.Description}");
            Console.WriteLine($"Url: {web.Url}");
        }
    }

    // Convert string to SecureString
    private static System.Security.SecureString ConvertToSecureString(string password)
    {
        if (password == null)
            throw new ArgumentNullException(nameof(password));

        var securePassword = new System.Security.SecureString();
        foreach (char c in password)
            securePassword.AppendChar(c);

        return securePassword;
    }
}
