服务的响应无法处理压缩响应，所以是的，您必须放置中间件才能继续进行解压缩。
首先，您需要将BFM WSDL作为服务导入而不是作为Web服务，因此：
然后，我创建了两个类，一个是调用BFM（“ BFM_v410Service ”）的类，另一个是中间件（“ BFMInspector ”）。
让我们从BFMInspector开始：
// The inspector class has to implement both IClientMessageInspector and IEndpointBehavior interfaces
public class BFMInspector : IClientMessageInspector, IEndpointBehavior
{
// This is the method to action after receiving a response from Sabre
public void AfterReceiveReply(ref Message reply, object correlationState)
{
try
{
// Get compressed response from reply and load that into a byte array.
XmlDictionaryReader bodyReader = reply.GetReaderAtBodyContents();
bodyReader.ReadStartElement("CompressedResponse");
byte[] bodyByteArray = bodyReader.ReadContentAsBase64();
// Create some helper variables
StringBuilder uncompressed = new StringBuilder();
String xmlString = "";
XmlDocument xmlPayload = new XmlDocument();
// Load the byte array into memory
using (MemoryStream memoryStream = new MemoryStream(bodyByteArray))
{
// Unzip the Stream
using (GZipStream gZipStream = new GZipStream(memoryStream, CompressionMode.Decompress))
{
byte[] buffer = new byte[1024];
int readBytes;
// Unzips character by character
while ((readBytes = gZipStream.Read(buffer, 0, buffer.Length)) != 0)
{
for (int i = 0; i < readBytes; i++)
// Append all characters to build the response
uncompressed.Append((char)buffer[i]);
}
}
xmlString = uncompressed.ToString();
xmlString = xmlString.Replace("<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"no\"?>", "");
}
// Convert the string into an XML
xmlPayload.LoadXml(xmlString);
// Create a new Message, which is what will substitute what was returned by Sabre
Message tempMessage = Message.CreateMessage(reply.Version, null, xmlPayload.ChildNodes[0]);
tempMessage.Headers.CopyHeadersFrom(reply.Headers);
tempMessage.Properties.CopyProperties(reply.Properties);
MessageBuffer bufferOfFault = tempMessage.CreateBufferedCopy(Int32.MaxValue);
// Replace the reply with the new Message
reply = bufferOfFault.CreateMessage();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
public object BeforeSendRequest(ref Message request, IClientChannel channel)
{
// Nothing is done here, so we simply return null
return null;
}
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
// Nothing done
}
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
// Add "this" as an endpoint to be inspected
clientRuntime.MessageInspectors.Add(this);
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
// Nothing done
}
public void Validate(ServiceEndpoint endpoint)
{
// Nothing done
}
}
现在，BFM_v410服务：
// BFM calling class
public class BFM_v410Service
{
// The constructor and CreateRequest simeply create a complete request
private BargainFinderMaxRQRequest service;
private OTA_AirLowFareSearchRQ request;
public OTA_AirLowFareSearchRS response;
private string endpoint;
public BFM_v410Service(string token, string pcc, string convId, string endpoint)
{
CreateRequest(pcc, true);
this.endpoint = endpoint;
service = new BargainFinderMaxRQRequest()
{
MessageHeader = new BargainFinderMaxRQ_3_4_0_Srvc.MessageHeader()
{
From = new From()
{
PartyId = new PartyId[]
{
new PartyId()
{
Value = pcc
}
}
},
To = new To()
{
PartyId = new PartyId[]
{
new PartyId()
{
Value = endpoint
}
}
},
ConversationId = convId,
CPAId = pcc,
Service = new Service()
{
Value = "BargainFinderMaxRQ"
},
Action = "BargainFinderMaxRQ",
MessageData = new MessageData()
{
Timestamp = DateTime.UtcNow.ToString("yyyy-MM-ddTHH:mm:ssK")
}
},
OTA_AirLowFareSearchRQ = request,
Security = new Security()
{
BinarySecurityToken = token
}
};
}
private void CreateRequest(string pcc, bool compressed)
{
request = new OTA_AirLowFareSearchRQ()
{
Version = "3.4.0",
POS = new SourceType[]
{
new SourceType()
{
PseudoCityCode = pcc,
RequestorID = new UniqueID_Type()
{
ID = "1",
Type = "1",
CompanyName = new CompanyNameType()
{
Code = "TN",
Value = "TN"
}
}
}
},
OriginDestinationInformation = new OTA_AirLowFareSearchRQOriginDestinationInformation[]
{
new OTA_AirLowFareSearchRQOriginDestinationInformation()
{
RPH = "1",
Item = "2018-09-21T11:00:00",
ItemElementName = ItemChoiceType.DepartureDateTime,
OriginLocation = new OriginDestinationInformationTypeOriginLocation()
{
LocationCode = "MVD"
},
DestinationLocation = new OriginDestinationInformationTypeDestinationLocation()
{
LocationCode = "KRK"
}
},
new OTA_AirLowFareSearchRQOriginDestinationInformation()
{
RPH = "2",
Item = "2018-09-28T11:00:00",
ItemElementName = ItemChoiceType.DepartureDateTime,
OriginLocation = new OriginDestinationInformationTypeOriginLocation()
{
LocationCode = "KRK"
},
DestinationLocation = new OriginDestinationInformationTypeDestinationLocation()
{
LocationCode = "MVD"
}
}
},
TravelerInfoSummary = new TravelerInfoSummaryType()
{
AirTravelerAvail = new TravelerInformationType[]
{
new TravelerInformationType()
{
PassengerTypeQuantity = new PassengerTypeQuantityType[]
{
new PassengerTypeQuantityType()
{
Code = "ADT",
Quantity = "1"
}
}
}
}
},
TPA_Extensions = new OTA_AirLowFareSearchRQTPA_Extensions()
{
IntelliSellTransaction = new TransactionType()
{
RequestType = new TransactionTypeRequestType()
{
Name = "50ITINS"
},
CompressResponse = new TransactionTypeCompressResponse()
{
Value = compressed
}
}
}
};
}
public void Execute()
{
try
{
// Instanciate the Inspector
BFMInspector inspector = new BFMInspector();
// Select the URL you'll be sending the request. I've passed this as a parameter in the constructor
EndpointAddress url = new EndpointAddress(new Uri(endpoint));
// Create a binding, with a couple of characteristics, because of the size of the response
Binding binding = new BasicHttpsBinding()
{
MaxReceivedMessageSize = Int32.MaxValue,
MaxBufferSize = Int32.MaxValue
};
// Create the executable the BargainFinderMaxPortTypeClient variable, which will allow me to call the service
BargainFinderMaxPortTypeClient execute = new BargainFinderMaxPortTypeClient(binding, url);
// Add the middleware. Here's where ApplyClientBehavior is called behind the scene and adds itself
execute.Endpoint.EndpointBehaviors.Add(inspector);
// Call BFM and successfully get the response as an OTA_AirLowFareSearchRS object
response = execute.BargainFinderMaxRQ(ref service.MessageHeader, ref service.Security, request);
Console.WriteLine(response);
}
catch(Exception ex)
{
Console.WriteLine(ex.Message);
}
}
}
然后，只需从控制台应用程序中调用它：
static void Main(string[] args)
{
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12;
string token = @"Shared/IDL:IceSess\/SessMgr:1\.0.IDL/Common/!ICESMS\/RESA!ICESMSLB\/RES.LB!-3146624380791354996!413892!0!1!E2E-1";
string pcc = "XXXX";
string convId = "HERE GOES YOUR CONVERSATION ID";
string endpoint = "https://webservices.havail.sabre.com";
BFM_v410Service bfm340 = new BFM_v410Service(token, pcc, convId, endpoint);
bfm410.Execute();
}
希望这有帮助！
