托管WCF REST和的net.tcp在Azure上一起端点与ASP.NET

Question

我通过在Windows Azure上的ASP.NET应用程序托管我的REST服务。它的工作非常完美，但几天前我需要一个角色间通信服务，我建立了我的服务，但我在托管服务时遇到了问题。

这段代码在我的Global.asax工作在我的本地Azure的开发服务器伟大的，但它并没有在碧霞工作。

什么是正确收留他们的最好方法？

Global.asax中：

public class Global : HttpApplication 
{ 
    void Application_Start(object sender, EventArgs e) 
    { 
     StartNotificationServiceHost(); 
     RegisterRoutes(); 
    } 

    public ServiceHost ServiceHost { get; private set; } 
    private void RegisterRoutes() 
    { 
     var hostfactory = new WebServiceHostFactory(); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Companies",hostfactory, typeof(Companies))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Public", hostfactory, typeof(Public))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Users", hostfactory, typeof(Users))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Contacts", hostfactory, typeof(Contacts))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Projects", hostfactory, typeof(Projects))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Instances", hostfactory, typeof(Instances))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Activity", hostfactory, typeof(Activity))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Search", hostfactory, typeof(Search))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Tasks", hostfactory, typeof(Tasks))); 
     RouteTable.Routes.Add(new ServiceRoute("REST/Documents", hostfactory, typeof(Documents))); 
    } 
    private void StartNotificationServiceHost() 
    { 
     Trace.WriteLine("Starting Service Host", "Information"); 
     NotificationServiceHost serviceHostBase = new NotificationServiceHost(); 
     serviceHostBase.RecycleNotificationRecieved += new RecycleNotificationRecievedEventHandler(ServiceHost_RecycleNotificationRecieved); 
     serviceHostBase.CheckInstanceStatusRecieved += new CheckInstanceStatusRecievedEventHandler(serviceHostBase_CheckInstanceStatusRecieved); 
     ServiceHost = new ServiceHost(serviceHostBase); 
     this.ServiceHost.Faulted += (sender, e) => 
     { 
      Trace.TraceError("Service Host fault occured"); 
      this.ServiceHost.Abort(); 
      Thread.Sleep(500); 
      this.StartNotificationServiceHost(); 

     }; 
     NetTcpBinding binding = new NetTcpBinding(SecurityMode.None); 
     RoleInstanceEndpoint notificationServiceHostEndPoint = RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["NotificationServiceEndPoint"]; 
     this.ServiceHost.AddServiceEndpoint(
      typeof(INotifyService), 
      binding, 
      String.Format("net.tcp://{0}/NotifyService", notificationServiceHostEndPoint.IPEndpoint) 
      ); 
     try 
     { 
      this.ServiceHost.Open(); 
      Trace.TraceInformation("Service Host Opened"); 
     } 
     catch (TimeoutException timeoutException) 
     { 
      Trace.TraceError("Service Host open failure, Time Out: " + timeoutException.Message); 
     } 
     catch (CommunicationException communicationException) 
     { 
      Trace.TraceError("Service Host open failure, Communication Error: " + communicationException.Message); 
     } 
     Trace.WriteLine("Service Host Started", "Information"); 
    } 
     InstanceItem serviceHostBase_CheckInstanceStatusRecieved(object sender, int e) 
     { 
... 
     } 
     void ServiceHost_RecycleNotificationRecieved(object sender, NotificationMessage e) 
     { 
... 

     } 
}

错误：

The server encountered an error processing the request. The exception message is 'Could not connect to net.tcp://x.x.x.29:8000/NotifyService. The connection attempt lasted for a time span of 00:00:21.0918600. TCP error code 10060: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond x.x.x.29:8000.

角色实例访问已被防火墙的限制。通常，该实例仅接受来自负载平衡器的连接。如下将设置添加到服务定义文件（* .csdef），并且有必要接受连接。

 
<?xml version="1.0" encoding="utf-8" ?> 
    <ServiceDefinition name="RoleCommunication" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition"> 
: 
    <NetworkTrafficRules> 
    <OnlyAllowTrafficTo> 
     <Destinations> 
     <RoleEndpoint endpointName="YourEndPointName" roleName="YourRole" /> 
     <Destinations> 
     <WhenSource matches="AnyRole"> 
     <FromRole roleName="YourRole" /> 
     </WhenSource> 
    </OnlyAllowTrafficTo> 
    </NetworkTrafficRules> 
</ServiceDefinition > 

或者，您可以在启动任务中使用netsh命令显式添加规则连接。

前） 的netsh advfirewall防火墙添加规则名称= “YourEndPoint” DIR =行动=允许将localPort = 80协议= TCP

====

是 'InternalEndpoint' 动态端口？如果可能，您可以在.csdef和启动任务中设置固定端口。

前）

 
<InternalEndpoint name="NotificationServiceEndPoint" protocol="tcp" port="8000"/> 

和

 
netsh advfirewall firewall add rule name="NotificationServiceEndPoint" dir=in action=allow localport=8000 protocol=tcp 

====

或者，环境变量可用如下：

 
    <Endpoints> 
     <InputEndpoint name="Endpoint1" protocol="http" port="80" /> 
     <InternalEndpoint name="NotificationServiceEndPoint" protocol="tcp" /> 
    </Endpoints> 

     <Startup> 
      <Task commandLine="configfirewall.cmd" executionContext="elevated" taskType="simple"> 
       <Environment> 
        <Variable name="NotificationServiceEndPointPort" value="/RoleEnvironment/CurrentInstance/Endpoints/Endpoint[@name='NotificationServiceEndPoint']/@port" /> 
       </Environment> 
      </Task> 
     </Startup> 

，并使用环境变量在启动任务

 
netsh advfirewall firewall add rule name="ServiceEndPoint" dir=in action=allow localport=%NotificationServiceEndPointPort% protocol=tcp
