我们有一种情况,我们一直在使用基于WCF的普通Windows服务,我们在同一地址上托管了许多监听器,端口只有地址上的附加后缀,例如:
http://localhost:9000/<listener1_name>/
http://localhost:9000/<listener2_name>/
http://localhost:9000/<listener3_name>/
http://localhost:9000/<listener4_name>/
然而,现在我们希望通过使用服务结构转移到asuze,我们喜欢一步一步地采取它。 其中一个步骤是将此Windows服务移动到Service Fabric环境中......
我没有做到的就像您可能意识到的那样,设置一些无状态服务来侦听同一个端口,但后缀不同。
我认为PathSuffix
中的EndPoint
属性可以解决问题,但我只启动并运行其中一个服务。其他人明确表示该港口已被占用。
希望这可行:
<Resources>
<Endpoints>
<Endpoint Name="WcfService1Endpoint" Protocol="tcp" Port="9000" PathSuffix="Service1ListenerName" /
<Endpoints>
</Resources>
然后在下一个:
<Resources>
<Endpoints>
<Endpoint Name="WcfService2Endpoint" Protocol="tcp" Port="9000" PathSuffix="Service2ListenerName" />
<Endpoints>
</Resources>
Etc等......
有没有其他方法可以解决我的情况,或者我现在需要改变整个结构吗?
希望有人解决这个问题!
谢谢!

好的,这就是我这样做的方式:
我构建了一个基类
public class StatelessServiceBase : StatelessService
{
.
.
.
protected ICommunicationListener CreateListener(StatelessServiceContext context, object service, string interfaceName, AuthenticationInspector inspector = null)
{
Uri baseUri = new Uri($"{Util.GetBaseServerAddress()}{service.GetType().Name}");
ServiceHost serviceHost = new ServiceHost(service.GetType(), baseUri);
this.AddServiceEndpoint(serviceHost, service, interfaceName, inspector);
return new ServiceHostCommunicationListener(serviceHost, baseUri.AbsoluteUri);
}
private void AddServiceEndpoint(ServiceHost serviceHost, object service, string interfaceName, AuthenticationInspector inspector)
{
var binding = new WSHttpBinding(SecurityMode.None);
binding.SendTimeout = new TimeSpan(0, 10, 0);
binding.ReceiveTimeout = new TimeSpan(0, 10, 0);
binding.MaxBufferPoolSize = 2147483647;
binding.MaxReceivedMessageSize = 2147483647;
binding.ReaderQuotas = new System.Xml.XmlDictionaryReaderQuotas
{
MaxDepth = 2147483647,
MaxStringContentLength = 2147483647,
MaxArrayLength = 2147483647,
MaxBytesPerRead = 2147483647,
MaxNameTableCharCount = 2147483647
};
if (inspector == null)
{
serviceHost.AddServiceEndpoint(service.GetType().GetInterface(interfaceName), binding, string.Empty);
}
else
{
serviceHost.AddServiceEndpoint(service.GetType().GetInterface(interfaceName), binding, string.Empty).Behaviors.Add(inspector);
}
}
}
然后我从无状态服务类调用CreateListener:
internal class MyStatelessService : StatelessServiceBase
{
public MyStatelessService(StatelessServiceContext context)
: base(context)
{
}
protected override IEnumerable<ServiceInstanceListener> CreateServiceInstanceListeners()
{
yield return new ServiceInstanceListener(context =>
this.CreateListener(context, new MyService(), "IMyService", new AuthenticationInspector()));
}
}
Settings.xml看起来像这样:
<?xml version="1.0" encoding="utf-8" ?>
<Settings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.microsoft.com/2011/01/fabric">
<Section Name="Configuration">
<Parameter Name="BaseServerAddress" Value="http://localhost:9000/"/>
</Section>
</Settings>
与读者功能一起:
public class Util
{
internal static string GetBaseServerAddress()
{
var configurationPackage = FabricRuntime.GetActivationContext().GetConfigurationPackageObject("Config");
var baseServerAddress =
configurationPackage.Settings.Sections["Configuration"].Parameters["BaseServerAddress"];
return baseServerAddress.Value;
}
}
在服务结构中添加多项服务......工作就像一个魅力! :)
