3 WCF一些基础铺垫

1首先上一张wcf通讯图

a.Proxy代理部分底层调用的是 xxxxClient=> ChannelFactory=>IInpuChannel/IOutChannel...

b.Transaction、Encoding、Security、transport这些则被封装在了协议栈里面 如BasicHttpBinding协议栈 

 

2.很重要的一个知识点，当创建一个binding节点要使其有效，我们要在endPoint节点中添加一个bindingConfiguration的属性，将属性值设置成我们定义的binding节点的名字。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
  </startup>
  <system.serviceModel>
    <!--以下  新加入的bindings节点-->
    <bindings>
      <netTcpBinding>
        <binding name="MyBinding">
          <security mode="None"></security><!--不要安全-->
        </binding>
      </netTcpBinding>
    </bindings>
    <!--以上  新加入的bindings节点-->
    
    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service name="WcfService.HomeService">
        <host>
          <baseAddresses>
            <!--<add baseAddress="http://localhost:8733/Design_Time_Addresses/WcfService/HomeService/" />-->
            <add baseAddress="http://localhost:8733/Design_Time_Addresses/WcfService/HomeService" />
          </baseAddresses>
        </host>
        <!--在endPoint这个节点的最后加入了属性 MyBinding-->
        <endpoint address="" binding="netTcpBinding" contract="WcfService.IHomeService" bindingConfiguration="MyBinding">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />

      </service>
    </services>
  </system.serviceModel>
</configuration>
