在.net 4.5中创建Saber SOAP会话失败

Question

我正在构建一个POC（windows项目）并试图调用saber会话创建请求。我有用于生成WSDL的sts url，并且可以在Visual studio 2015中使用链接http://webservices.sabre.com/wsdl/sabreXML1.0.00/usg/SessionCreateRQ.wsdl使用.net 4.5生成代理类。现在我有Sabre超出了我公司的用户ID和密码，我尝试将它们放在请求中，如在“Consuming Sabre soap services using .net”后的建议中，但没有运气，因为在新的CRT url调用服务时，代理类对象发生错误（https://sws-crt-as.cert.havail.sabre.com）Sabre。异常：“System.ServiceModel.Security.SecurityNegotiationException：无法为权限为'sws-crt-as.cert.havail.sabre.com'的SSL/TLS建立安全通道。” - > System.Net.WebException：请求被中止：无法创建SSL/TLS安全通道。“这里有任何内部异常（具有与外部异常相同的文本），它将异常的InternalSTatus属性指示为“RequestFatal”。在app.config的内容在这里给出的参考以及

请帮我点的错误（可能在web.config中/代码）

代码来创建会话：

public SabreSessionInfo sabreCreateSession(string user, string pass, string pseudo, string org, bool doGetAirVendors) 
{ 
    SabreSessionInfo inf = new SabreSessionInfo(); 

    try 
    { 
     string userName = user; 
     string password = pass; 

     string PCC = pseudo; 

     string domain = "LA"; 

     DateTime dt = DateTime.UtcNow; 
     string tstamp = dt.ToString("s").Replace("-","").Replace(":","") + "Z"; 

     SessionCreate.MessageHeader msgHeader = new SessionCreate.MessageHeader(); 

     msgHeader.ConversationId = tstamp; 

     SessionCreate.From from = new SessionCreate.From(); 
     SessionCreate.PartyId fromPartyId = new SessionCreate.PartyId(); 
     SessionCreate.PartyId[] fromPartyIdArr = new SessionCreate.PartyId[1]; 
     fromPartyId.Value = "99999"; 
     fromPartyIdArr[0] = fromPartyId; 
     from.PartyId = fromPartyIdArr; 
     msgHeader.From = from; 

     SessionCreate.To to = new SessionCreate.To(); 
     SessionCreate.PartyId toPartyId = new SessionCreate.PartyId(); 
     SessionCreate.PartyId[] toPartyIdArr = new SessionCreate.PartyId[1]; 
     toPartyId.Value = "123123"; 
     toPartyIdArr[0] = toPartyId; 
     to.PartyId = toPartyIdArr; 
     msgHeader.To = to; 

     //Add the value for eb:CPAId, which is the IPCC. 
     //Add the value for the action code of this Web service, SessionCreateRQ. 

     msgHeader.CPAId = "AnyCPA"; 
     msgHeader.Action = "SessionCreateRQ";// Web method name 
     SessionCreate.Service service = new SessionCreate.Service(); 
     service.Value = "Session"; 
     msgHeader.Service = service; 

     SessionCreate.MessageData msgData = new SessionCreate.MessageData(); 
     msgData.MessageId = "mid:" + tstamp + "@clientofsabre.com"; 
     msgData.Timestamp = tstamp; 
     msgHeader.MessageData = msgData; 

     SessionCreate.Security security = new SessionCreate.Security(); 
     SessionCreate.SecurityUsernameToken securityUserToken = new SessionCreate.SecurityUsernameToken(); 
     securityUserToken.Username = userName; 
     securityUserToken.Password = password; 
     securityUserToken.Organization = org; 
     securityUserToken.Domain = domain; 
     security.UsernameToken = securityUserToken; 

     SessionCreate.SessionCreateRQ req = new SessionCreate.SessionCreateRQ(); 
     SessionCreate.SessionCreateRQPOS pos = new SessionCreate.SessionCreateRQPOS(); 
     SessionCreate.SessionCreateRQPOSSource source = new SessionCreate.SessionCreateRQPOSSource(); 
     source.PseudoCityCode = PCC; 
     pos.Source = source; 
     req.POS = pos; 

     SessionCreate.SessionCreatePortTypeClient clientObj = new SessionCreate.SessionCreatePortTypeClient("SessionCreatePortType"); 
     Task<SessionCreate.SessionCreateRQResponse> resp = clientObj.SessionCreateRQAsync(msgHeader, security, req); 
     resp.Wait(); 

     inf.conversationID = msgHeader.ConversationId; 
     inf.sabreToken = security.BinarySecurityToken; 
    } 
    catch (Exception ex) 
    { 
     System.Diagnostics.Debug.WriteLine(ex.ToString()); 
    } 
    return inf; 
}

问题是URL只接受TLS 1.2，默认情况下可能不启用。

在类中，你执行实例化对象SessionCreate，添加以下行： System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;

这应该解决这个问题。
