尝试远程连接时远程证书无效答案

【问题标题】：The remote certificate is invalid when trying to remotely connect尝试远程连接时远程证书无效

【问题描述】：

我有一个我编写的 asp.net 4.0 脚本，它基本上用于从安全站点获取 RSS 提要（我们使用 SSO 解决方案）。该脚本将正确的凭据发布到表单并收集所有 cookie，然后使用这些 cookie 再次发出请求。我遇到的问题是，当我从服务器请求它时，我收到错误"The remote certificate is invalid according to the validation procedure."

在与我们的一位处理证书的人交谈后，他说这与我们购买的证书类型有关。基本上他告诉我，他无能为力。

我的问题是如何阻止此错误出现并让我的脚本正常工作？

            CookieContainer cookieJar = new CookieContainer();

            HttpWebRequest wr = (HttpWebRequest)HttpWebRequest.Create("OURADDRESS");
            wr.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 3.5.30729;)";
            wr.Method = "POST";
            wr.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            wr.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
            wr.KeepAlive = true;
            wr.Headers.Add("Keep-Alive: 300");
            wr.AllowAutoRedirect = false;

            wr.ContentType = "application/x-www-form-urlencoded";

            wr.CookieContainer = cookieJar;

            StreamWriter sw = new StreamWriter(wr.GetRequestStream());
            sw.Write("USER=" + UserName + "&PASSWORD=" + Password);
            sw.Close();

            HttpWebResponse response = (HttpWebResponse)wr.GetResponse();

            foreach (Cookie cookie in response.Cookies)
            {
                cookieJar.Add(new Cookie(cookie.Name.Trim(), cookie.Value.Trim(), cookie.Path, cookie.Domain));
            }

            HttpWebRequest request2 = (HttpWebRequest)HttpWebRequest.Create(RssFeedLink);
            request2.UserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 3.5.30729;)";
            request2.Method = "GET";
            request2.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
            request2.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
            request2.KeepAlive = true;
            request2.Headers.Add("Keep-Alive: 300");
            request2.CookieContainer = cookieJar;

            request2.ContentType = "text/html";

            HttpWebResponse response2 = (HttpWebResponse)request2.GetResponse();
            StreamReader reader2 = new StreamReader(response2.GetResponseStream());

我在 SO 的其他地方遇到了这个问题 ("The remote certificate is invalid according to the validation procedure." using Gmail SMTP server)。但是，该解决方案也适用于此：

            ServicePointManager.ServerCertificateValidationCallback = (s, certificate, chain, errs) => true;
