如何以编程方式更新SharePoint Web部件中的内容？

using System;
using System.Security;
using Microsoft.SharePoint.Client;

namespace UpdateWebPartContent
{
    class Program
    {
        static void Main(string[] args)
        {
            string siteUrl = "https://your-domain.sharepoint.com/sites/your-site";
            string username = "your-username";
            string password = "your-password";

            using (ClientContext context = new ClientContext(siteUrl))
            {
                SecureString securePassword = new SecureString();
                foreach (char c in password)
                {
                    securePassword.AppendChar(c);
                }

                context.Credentials = new SharePointOnlineCredentials(username, securePassword);

                // Update web part content here
            }
        }
    }
}

const siteUrl = "https://your-domain.sharepoint.com/sites/your-site";
const username = "your-username";
const password = "your-password";

const headers = {
    "Accept": "application/json;odata=verbose",
    "Content-Type": "application/json;odata=verbose",
};

const auth = {
    username,
    password,
};

const axios = require("axios");

(async () => {
    try {
        // Update web part content here
    } catch (error) {
        console.error(error);
    }
})();
