Answer 1

异常很简单：
{"Unable to connect to the remote server"}{"A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 202.40.243.120:443"}

Answer 2

   sendUrl=https://smsgw.saasconnect.com/obh/SendSMSLegacyBC就是这个地址！

Answer 3

完全没有人来帮忙解决一下吗？？
我修改了代码如下，还是不行   string SenSMSUrl = sendUrl;
            byte[] bytes = Encoding.UTF8.GetBytes(SendSMSOnBehalfReq.InnerXml.ToString());            HttpWebRequest request;
            ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback(CheckValidationResult);
            request = WebRequest.Create(SenSMSUrl) as HttpWebRequest;
            request.ProtocolVersion = HttpVersion.Version10;            request.Method = "POST";
            request.ContentLength = bytes.Length;
            //request.ContentType = "application/x-www-form-urlencoded";
            request.Timeout = 50000;
            request.KeepAlive = true;
            request.ContentType = "text/xml";
            request.ServicePoint.Expect100Continue = false;            Stream requestStream;
            try
            {
                requestStream = request.GetRequestStream();
                requestStream.Write(bytes, 0, bytes.Length);
                requestStream.Close();
            }
            catch (Exception)
            {                throw;
            }            // using (Stream requestStream = request.GetRequestStream())
            //  {            //  }
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();            if (response.StatusCode != HttpStatusCode.OK)
            {
                string message = String.Format("POST failed. Received HTTP {0}", response.StatusCode);
                throw new ApplicationException(message);
            } private static bool CheckValidationResult(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
        {
            return true;
        }

Answer 4

ServicePointManager.CheckCertificateRevocationList = false;

Answer 5

另外，你这个是不是应该用 GET 呀

Answer 6

换成   request.Method = "GET";  ServicePointManager.CheckCertificateRevocationList = false;之后报错
{"Cannot send a content-body with this verb-type."}还是不行呀

Answer 7

对了、干嘛要用“GET”方法呢？

Answer 8

没有，我以为你是第一次登录。没看到你往Request有写流，那还用POST吧。
