Question

我有一个asp.net 4.0脚本，我写的基本上是从安全站点获取RSS源（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."

在与我们处理证书的人谈话后，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运行？

            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，解决方案也适用于此：

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

尝试远程连接时，远程证书无效
