我有一个自托管的WCF服务,并在调用它时收到以下异常:
The message with To ‘net.tcp://localhost:53724/Test1’ cannot be
processed at the receiver, due to an AddressFilter mismatch at the
EndpointDispatcher. Check that the sender and receiver’s
EndpointAddresses agree.
有效的解决方案是在服务接口的实现类之前添加[ServiceBehavior(AddressFilterMode = AddressFilterMode.Prefix)].但事实并非如此!所以,我试图找到错误的来源,以便删除它.
我发现了
当我添加ServiceBehavior属性并且调用成功时 – 以下内容:OperationContext.Current.EndpointDispatcher.EndpointAddress
返回:net.tcp:// localhost / Test1 – 注意没有端口.这实际上是我为ServiceHost.Open方法提供的.但添加端口是因为我指定了ListenUriMode.Unique.
那么:如何使用AddressFilterMode.Exact修复错误?
代码重现:
[ServiceContract]
public interface IWCF1
{
[OperationContract]
bool SendMessage(string message);
}
[ServiceBehavior(AddressFilterMode = AddressFilterMode.Prefix)]
public class WCF1 : IWCF1
{
public bool SendMessage(string message)
{
Debug.WriteLine("Message: " + message);
Debug.WriteLine(OperationContext.Current.EndpointDispatcher.EndpointAddress, "EndpointAddress");//Does not include the port!
return true;
}
}
public void test()
{
Uri uri2 = Service(typeof(WCF1), typeof(IWCF1), "Test1");
IWCF1 iwcf1 = CreateChannel(uri2.ToString());
new Task(() => iwcf1.SendMessage("abc")).Start();
}
public Uri Service(Type class1, Type interface1, string uri)
{
string serviceUri = "net.tcp://localhost/" + uri;
ServiceHost host = new ServiceHost(class1, new Uri(serviceUri));
ServiceEndpoint ep = host.AddServiceEndpoint(interface1, new NetTcpBinding(SecurityMode.None), serviceUri);
ep.ListenUriMode = ListenUriMode.Unique;
host.Open();
return host.ChannelDispatchers[0].Listener.Uri;
}
public static IWCF1 CreateChannel(string address)
{
EndpointAddress ep = new EndpointAddress(address);
ChannelFactory<IWCF1> channelFactory = new ChannelFactory<IWCF1>(new NetTcpBinding(SecurityMode.None), ep);
return channelFactory.CreateChannel();
}
最佳答案 我怀疑AddressFilterMode.Exact错误的来源涉及逻辑端点和物理服务地址之间的差异.
EndpointAddress是服务的逻辑地址,它是SOAP消息发送到的地址. ListenUri是服务的物理地址.它具有端口和地址信息,服务端点实际上侦听当前计算机上的消息.调度程序使用逻辑端点地址而不是物理服务位置进行匹配和过滤,因此精确匹配找不到服务的原因.
物理地址与逻辑地址不同:
net.tcp://localhost:53724/Test1 != net.tcp://localhost/Test1
一些选项需要考虑:
继续使用AddressFilterMode.Prefix
尝试指定HostNameComparisonMode
提前指定端口
