C#的Web请求WebClient之https根据验证过程，远程证书无效

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
        using (WebClient client = new WebClient())
        {
            string url = "https://api.example.com/data";
            string response = client.DownloadString(url);
            Console.WriteLine(response);
        }

以前一直使用第三方或是webrequest 之类 新的来了 就使用一下 结果还https的请求 根据验证过程，远程证书无效

特此记录一句

ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;
