使用tcpTrace监听wcf消息

下面是服务端的配置文件。服务端终结点地址是http://localhost:3721/calculatorservice，逻辑地址和物理地址统一，物理地址就是监听地址。

<configuration>  <system.serviceModel>    <behaviors>      <serviceBehaviors>        <behavior name="metadataBehavior">          <serviceMetadata httpGetEnabled="true"                            httpGetUrl="http://localhost:3721/calculatorservice/metadata" />        </behavior>      </serviceBehaviors>    </behaviors>    <services>      <service name="Artech.WcfServices.Service.CalculatorService"               behaviorConfiguration="metadataBehavior" >        <endpoint address="http://localhost:3721/calculatorservice"                  binding="wsHttpBinding"                   contract="Artech.WcfServices.Service.Interface.ICalculator" />      </service>    </services>  </system.serviceModel></configuration>

下面给出客户端的配置文件。通过clientViaBehavior这个终结点行为指定终结点的物理地址，而通过endpoint的address节点指定的地址是逻辑地址。

<configuration>  <system.serviceModel>    <behaviors>      <endpointBehaviors>        <behavior name="clientViaBehavior">          <clientVia viaUri="http://127.0.0.1:3722/calculatorservice"/>        </behavior>        </endpointBehaviors>    </behaviors>    <client>      <endpoint address="http://127.0.0.1:3721/calculatorservice" binding="wsHttpBinding"        contract="Artech.WcfServices.Service.Interface.ICalculator"        name="calculatorservice"                 behaviorConfiguration ="clientViaBehavior"/>    </client>  </system.serviceModel></configuration>

下面配置tcpTrace的监听地址和转发地址。tcpTrace就是一个消息的中介，客户端本来要将消息发送给3721，现在先将消息发送给3722，再转发给3721。

启动服务，执行服务调用，tcpTrace可以截获服务的请求和回复消息。
