我需要在REST、Json、WCF web服务中使用请求头。我创建我的IDispatchMessageInspector
public class HeaderInspector : IDispatchMessageInspector
{
public object AfterReceiveRequest(ref System.ServiceModel.Channels.Message request, System.ServiceModel.IClientChannel channel, System.ServiceModel.InstanceContext instanceContext)
{
int ind = request.Headers.FindHeader("xxxxx", "");
return null;
}
public void BeforeSendReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
{
}
}
然后是将检查器连接到端点的端点行为:
public class HeaderInspectorBehavior : IEndpointBehavior
{
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
}
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
}
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
HeaderInspector headerinsp = new HeaderInspector();
endpointDispatcher.DispatchRuntime.MessageInspectors.Add(new HeaderInspector());
}
public void Validate(ServiceEndpoint endpoint)
{
}
}
最后是一个行为扩展元素:
public class MyExtension : BehaviorExtensionElement
{
public override Type BehaviorType
{
get { return typeof(HeaderInspectorBehavior); }
}
protected override object CreateBehavior()
{
return new HeaderInspectorBehavior();
}
}
那些类位于同一文件/命名空间PDM.WebService中我的配置是:
<behaviors>
<endpointBehaviors>
<behavior name="RestBehavior">
<HeaderInspectorBehavior/>
<webHttp helpEnabled="true" defaultOutgoingResponseFormat="Json" faultExceptionEnabled="true" automaticFormatSelectionEnabled="false" />
</behavior>
</endpointBehaviors>
</behaviors>
<extensions>
<behaviorExtensions>
<add name="HeaderInspectorBehavior" type="PDM.WebService.MyExtension, PDM.WebService, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
</behaviorExtensions>
</extensions>
一切都编译得很好,在执行时我可以捕捉到方法"public override Type BehaviorType"的执行,但在那之后,没有其他代码方法被激发(我发送了请求,得到了响应,服务响应良好)。我在每个方法中都设置了调试点,其他方法都不执行!(尤其是ApplyDispatchBehavior)。有人能指出我遗漏了什么吗?
Refer CreateBehavior()不会针对类似问题调用。
确保您的服务元素的名称与mynamespace.myservicename
相对应
即使您没有正确的服务名称,该服务也会提供正确的响应;但是CCD_ 2只有在您具有服务元素的正确名称时才会被调用。
示例
<service
name="WcfServiceApp001.Service1"
behaviorConfiguration="InternalPayrollBehavior">
<endpoint address="" binding="basicHttpBinding"
behaviorConfiguration="EndpointBehavior"
contract="WcfServiceApp001.IService1"
/>
</service>
