c# - wcf卡在实时服务器上

Question

我正在开发一个测试项目来实现 wcf 回调，当我在本地调试时我的代码可以正常工作，然后回调实际上可以正常工作，但是当我连接到实时服务器时它会简单地卡住任何方法。

我尝试了所有的Conncurency模式，我尝试设置超时但都失败了

public interface IWorkplaySupportServiceCallBack
{
    [OperationContract(IsOneWay = true)]
    void HandleData(byte[] buffer);

    [OperationContract(IsOneWay = true)]
    void SessionCreated();
}

[ServiceContract(CallbackContract = typeof(IWorkplaySupportServiceCallBack))]
public interface IWorkplaySupportService
{
    [OperationContract(IsOneWay = true)]
    void CreateSession(string sessionId);
}

[CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant, UseSynchronizationContext = false)]
public class WorkplaySupportService : IWorkplaySupportService
{
    public void CreateSession(string sessionId)
    {
        var callback = OperationContext.Current.GetCallbackChannel<IWorkplaySupportServiceCallBack>();
        callback.SessionCreated();
    }
}

这是我的配置

  <!-- WCF START-->

<bindings>
  <wsDualHttpBinding>
    <binding name="basicHttpFor2MBMessage" maxBufferPoolSize="2097152"
      maxReceivedMessageSize="2097152" messageEncoding="Mtom">
      <readerQuotas maxArrayLength="2097000" />
      <security mode="None">
        <message clientCredentialType="None" />
      </security>
    </binding>
  </wsDualHttpBinding>
</bindings>
<services>
  <service behaviorConfiguration="wsDualHttpBinding.SampleServiceBehavior"
    name="Workflowms.Web.webservices.support.WorkplaySupportService">
    <endpoint address="" binding="wsDualHttpBinding" bindingConfiguration="basicHttpFor2MBMessage"
      contract="Workflowms.Web.webservices.support.IWorkplaySupportService">
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="wsDualHttpBinding.SampleServiceBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

通过使用 Trace 事件，我弄清楚了为什么它没有响应，但我不知道如何解决这个问题，连接的客户端是我的笔记本电脑，而服务器不在同一网络上(通过 Internet 连接)，我通过 Internet 添加 wcf 引用但是当我运行它时我没有连接，在服务器跟踪事件上我得到以下异常 在 http://donald-pc/Temporary_Listen_Addresses/f9dbbcde-f968-48f1-bc48-e1e12dd13e32/6ca1305c-95e4-4248-a5f3-cbb594ea8a26 处没有端点监听可以接受消息。这通常是由不正确的地址或 SOAP 操作引起的。有关详细信息，请参阅 InnerException(如果存在)。

我设法通过更改让它正常工作

<endpoint address="" binding="wsDualHttpBinding" bindingConfiguration="basicHttpFor2MBMessage"    contract="Workflowms.Web.webservices.support.IWorkplaySupportService">    </endpoint>

到

 <endpoint address="" binding="netHttpBinding" bindingConfiguration="netHttpBinding" contract="Workflowms.Web.webservices.support.IWorkplaySupportService">

并添加

   <netHttpBinding>
    <binding name="netHttpBinding" maxBufferPoolSize="2097152"
      maxReceivedMessageSize="2097152" messageEncoding="Mtom">
      <readerQuotas maxArrayLength="2097000" />
      <security mode="None">
        <transport clientCredentialType="None"></transport>
      </security>
    </binding>
  </netHttpBinding>

现在我的回调在 Intranet 和 Internet 上都有效
