我正在我的asp.net mvc 5应用程序中实现ups跟踪api。我创建了下面的方法。
public virtual Core.UPSTrackingResponse.UPSTrackingResponse TrackUPS(string trackingNumber)
{
Core.UPSTrackingRequest.UPSTrackingRequest requestModal = new Core.UPSTrackingRequest.UPSTrackingRequest();
requestModal.UPSSecurity.ServiceAccessToken.AccessLicenseNumber = UPSAccessKey;
requestModal.UPSSecurity.UsernameToken.Username = UPSUserId;
requestModal.UPSSecurity.UsernameToken.Password = UPSPassword;
requestModal.TrackRequest.InquiryNumber = trackingNumber;
requestModal.TrackRequest.Request.RequestOption = "1";
requestModal.TrackRequest.Request.TransactionReference.CustomerContext = trackingNumber + " tracking context";
string Data = new JavaScriptSerializer().Serialize(requestModal);
string response = "";
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls;
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(UPSTrackingURL); // https://wwwcie.ups.com/rest/Track
request.Method = "POST";
request.KeepAlive = false;
request.ProtocolVersion = HttpVersion.Version10;
request.ContentType = @"application/json";
request.ContentLength = Data.Length;
StreamWriter requestWriter = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII);
requestWriter.Write(Data);
requestWriter.Close();
try
{
WebResponse webResponse = request.GetResponse();
Stream webStream = webResponse.GetResponseStream();
StreamReader responseReader = new StreamReader(webStream);
response = responseReader.ReadToEnd();
Console.Out.WriteLine(response);
responseReader.Close();
Nop.Core.UPSTrackingResponse.UPSTrackingResponse ResponseModal =
new JavaScriptSerializer().Deserialize<Nop.Core.UPSTrackingResponse.UPSTrackingResponse>(response);
return ResponseModal;
}
catch (Exception ex)
{
return null;
}
}
当我在本地机器上调用它时，它工作得很好。但是当我在aws服务器上部署我的应用程序时，它总是给我以下异常。可能是什么原因，我现在卡住了。

最佳答案：
在调用webservice之前，请尝试在代码中的某个位置添加此内容：
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3
| System.Net.SecurityProtocolType.Tls
| System.Net.SecurityProtocolType.Tls11
| System.Net.SecurityProtocolType.Tls12;
