如何将自定义EndPointBehavior添加到服务的web.config? [英] How to add a Custom EndPointBehavior to the web.config of the service?

问题描述

我已关注这篇文章，并创建了如下的 MyMessageInspector 和 MyEndPointBehavior 类:

I have followed this article and have created MyMessageInspector and MyEndPointBehavior clases as below:

public class MyMessageInspector : IDispatchMessageInspector
{
    public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
    { 
        Console.WriteLine("Incoming request: {0}", request);
        return null;
    }

    public void BeforeSendReply(ref Message reply, object correlationState)
    {
    }
}

public class MyEndPointBehavior : IEndpointBehavior
{
    #region IEndpointBehavior Members

    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    {
        ChannelDispatcher channelDispatcher = endpointDispatcher.ChannelDispatcher;
        if (channelDispatcher != null)
        {
            foreach (EndpointDispatcher ed in channelDispatcher.Endpoints)
            {
                ed.DispatchRuntime.MessageInspectors.Add(new MyMessageInspector());
            }
        }
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }

    #endregion
}

如何将MyEndPointBehavior添加到web.config?

How to add MyEndPointBehavior to the web.config?

我添加了以下扩展名:

<extensions>
  <behaviorExtensions>
    <add name="myMessageInspector" type="MessageInspectorProject.MyEndPointBehavior, MessageInspectorProject, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
  </behaviorExtensions>
</extensions>

但是当我尝试在下面使用它时，它会抱怨:

But when I try to use it in below, it complains:

<serviceBehaviors>
    <behavior>
      <myMessageInspector/>

它的抱怨如下:

配置中的无效元素.扩展名"myMessageInspector"不是从正确的扩展名基本类型"System.ServiceModel.Configuration.BehaviorExtensionElement"派生的.

Invalid element in configuration. The extension 'myMessageInspector' does not derive from correct extension base type 'System.ServiceModel.Configuration.BehaviorExtensionElement'.

推荐答案

您还必须创建一个自定义 BehaviorExtensionElement 并将其用于web.config文件.有很多文章可以帮助您喜欢这些

You have to also create a custom BehaviorExtensionElement and use it in web.config file. There are many articles which can help you like these

无论如何以这种方式修复代码

Anyway fix your code to this way

public class MyMessageInspector : IDispatchMessageInspector
{
    public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
    {
        Console.WriteLine("Incoming request: {0}", request);
        return null;
    }

    public void BeforeSendReply(ref Message reply, object correlationState)
    {
    }
}

public class MyEndPointBehavior : IEndpointBehavior
{
    #region IEndpointBehavior Members

    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    {
        ChannelDispatcher channelDispatcher = endpointDispatcher.ChannelDispatcher;
        if (channelDispatcher != null)
        {
            foreach (EndpointDispatcher ed in channelDispatcher.Endpoints)
            {
                ed.DispatchRuntime.MessageInspectors.Add(new MyMessageInspector());
            }
        }
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }

    #endregion
}

在此处添加新的BehaviorExtensionElement

Here add new BehaviorExtensionElement

public class CustomBehaviorExtensionElement : BehaviorExtensionElement
{
    protected override object CreateBehavior()
    {
        return new MyEndPointBehavior();
    }

    public override Type BehaviorType
    {
        get
        {
            return typeof(MyEndPointBehavior);
        }
    }
}

并更新您的web.config

And update your web.config

<extensions>
  <behaviorExtensions>
    <add name="myMessageInspector" type="MessageInspectorProject.CustomBehaviorExtensionElement, MessageInspectorProject"/>
  </behaviorExtensions>
</extensions>

<behaviors>
  <endpointBehaviors>
    <behavior>
      <myMessageInspector />
    </behavior>
  </endpointBehaviors>
</behaviors>
