私の WCF サーバーは次のように動作します。たとえば、Subscribe() などのサービス メソッドを呼び出して、サーバーにサブスクライブします。MessageReceived(string message) などのコールバック チャネルで結果を返します。
現在の問題は、両方ではなく、1 つのサービス エンドポイントからのみコールバック メッセージを取得していることです。実際、デバッグするだけで、私の 2 番目のサービスがリクエストを受け取っていないことがわかります。誰が問題が何であるか知っていますか?これが私のコードです(serviceAddresses文字列に2つのnet.tcpアドレスがあることに注意してください):
private void StartAggregatorHost(List<string> serviceAddresses)
{
// Create a new service host for the routing service (note that RoutingService is a pre-defined Microsoft service model type which routes SOAP messages).
aggregatorHost = new ServiceHost(typeof(RoutingService));
// Set up the router address. A logger client will now connect to this address to get logged messages.
string fqdn = System.Net.Dns.GetHostEntry("localhost").HostName;
string routerAddress = string.Format("net.tcp://{0}:2099/LogAggregator", fqdn);
// Set up our router binding.
NetTcpBinding routerBinding = new NetTcpBinding(SecurityMode.None, true);
routerBinding.SendTimeout = new TimeSpan(0, 1, 0);
routerBinding.ReceiveTimeout = new TimeSpan(25, 0, 0);
routerBinding.MaxReceivedMessageSize = int.MaxValue;
routerBinding.MaxConnections = int.MaxValue;
routerBinding.ListenBacklog = int.MaxValue;
routerBinding.ReliableSession.Enabled = true;
routerBinding.ReliableSession.Ordered = true;
routerBinding.ReliableSession.InactivityTimeout = new TimeSpan(15, 0, 0, 0);
// Define the type of router in use. For duplex sessions like in our case, we want to use the IDuplexSessionRouter.
Type contractType = typeof(IDuplexSessionRouter);
// Add the endpoint that the router will use to recieve and relay messages. Note the use of System.ServiceModel.Routing.IDuplexSessionRouter.
aggregatorHost.AddServiceEndpoint(contractType, routerBinding, routerAddress);
// Create the endpoint list that contains the service endpoints we want to route to.
List<ServiceEndpoint> endpointList = new List<ServiceEndpoint>();
foreach (string serverAddress in serviceAddresses)
{
// Set up our server binding(s) for each server.
NetTcpBinding serverBinding = new NetTcpBinding(SecurityMode.None, true);
serverBinding.SendTimeout = new TimeSpan(0, 1, 0);
serverBinding.ReceiveTimeout = new TimeSpan(25, 0, 0);
serverBinding.MaxReceivedMessageSize = int.MaxValue;
serverBinding.MaxConnections = 1;
serverBinding.ListenBacklog = int.MaxValue;
serverBinding.ReliableSession.Enabled = true;
serverBinding.ReliableSession.Ordered = true;
serverBinding.ReliableSession.InactivityTimeout = new TimeSpan(15, 0, 0, 0);
// Create the server endpoint the router will route messages to and from.
ContractDescription contract = ContractDescription.GetContract(contractType);
ServiceEndpoint server = new ServiceEndpoint(contract, serverBinding, new EndpointAddress(serverAddress));
// Add the server to the list of endpoints.
endpointList.Add(server);
}
// Create a new routing configuration object.
RoutingConfiguration routingConfiguration = new RoutingConfiguration();
// Add a MatchAll filter to the Router's filter table. Map it to the endpoint list defined earlier. When a message matches this filter, it will be sent to the endpoint contained in the list.
routingConfiguration.FilterTable.Add(new MatchAllMessageFilter(), endpointList);
// Attach the behavior to the service host.
aggregatorHost.Description.Behaviors.Add(new RoutingBehavior(routingConfiguration));
// Open the service host.
aggregatorHost.Open();
m_eventLog.WriteEntry(string.Format("Log aggregator service hosted at {0}.", routerAddress), EventLogEntryType.Information);
}
だからもう一度...これが私が欲しいものです:
CLIENT ---REQ---> ROUTER ---REQ---> SVC1
---REQ---> SVC2
CLIENT <---CALLBACK1--- ROUTER <---CALLBACK1--- SVC1
<---CALLBACK2--- <---CALLBACK2--- SVC2
これは私が得ているものです(ルーターに2番目のサービスを追加しましたが、サービスメソッドを呼び出すことすらないようです):
CLIENT ---REQ---> ROUTER ---REQ---> SVC1
CLIENT <---CALLBACK--- ROUTER <---CALLBACK--- SVC1
