需要禁用RestSharp的SSL证书验证

using System;
using System.Net;
using RestSharp;

namespace RestSharpExample
{
    class Program
    {
        static void Main(string[] args)
        {
            // 创建自定义的证书验证委托
            ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

            // 创建RestClient对象
            var client = new RestClient("https://example.com");

            // 创建RestRequest对象
            var request = new RestRequest("/api/resource", Method.GET);

            // 发送请求
            var response = client.Execute(request);

            // 处理响应
            Console.WriteLine(response.Content);
        }
    }
}
