wcf - 在服务和客户端之间共享 WCF 设置

Question

WCF 服务和客户端是否可以共享关于绑定(bind)等的相同设置(来自相同的配置文件)，无论在什么情况下？换句话说，我是否可以编写一个绑定(bind)部分并放入任何内容并确保它对服务和客户都有好处？

我会更好地解释。我有一个这样的配置文件:

<services>
  <service name="TestClass1">
    <endpoint binding="basicHttpBinding" address="http://dev00:4322/host1/TestApplication1" contract="myApp.Interface.ITestApplication"/>
    <endpoint binding="netTcpBinding" bindingConfiguration="Binding1" address="net.tcp://dev00:4321/host1/TestApplication1" contract="myApp.Interface.ITestApplication"/>
    <endpoint binding="netNamedPipeBinding" address="net.pipe://localhost/host1/TestApplication1" contract="myApp.Interface.ITestApplication"/>
  </service>

  <service name="ManagementClass1">
    <endpoint binding="netNamedPipeBinding" address="net.pipe://localhost/host1/ManagementApplication1" contract="myApp.Interface.IManagementApplication"/>
    <endpoint binding="netTcpBinding" bindingConfiguration="Binding1" address="net.tcp://dev00:4321/host1/ManagementApplication1" contract="myApp.Interface.IManagementApplication"/>
  </service>
</services>

<client>
  <endpoint name="clientTestClass1Tcp"
      address="net.tcp://dev00:4321/host1/TestApplication1"
      binding="netTcpBinding" 
      bindingConfiguration="Binding1" 
      contract="myApp.Interface.ITestApplication"/>

  <endpoint name="clientManagementClass1Tcp"
      address="net.tcp://dev00:4321/host1/ManagementApplication1"
      binding="netTcpBinding" 
      bindingConfiguration="Binding1" 
      contract="myApp.Interface.IManagementApplication"/>
</client>

<bindings>
  <netTcpBinding>
    <binding name="Binding1" 
         closeTimeout="00:00:10"
         openTimeout="00:00:10" 
         receiveTimeout="00:01:00" 
         sendTimeout="00:01:00"
         transactionFlow="false" 
         transferMode="Buffered" 
         transactionProtocol="OleTransactions"
         hostNameComparisonMode="StrongWildcard" 
         listenBacklog="10"
         maxBufferPoolSize="524288" 
         maxBufferSize="65536" 
         maxConnections="30"
         maxReceivedMessageSize="65536">
      <security mode="None">
        <transport clientCredentialType="None" />
      </security>
    </binding>
  </netTcpBinding>
</bindings>

并非一切都在我的控制之下。我可以确定在服务和客户端之间共享绑定(bind)(和其他部分..)，无论编写什么，在服务和客户端中都运行良好吗？

是的，您可以 - 在某种程度上:

• 将您的绑定(bind)、行为、扩展信息放入单独的配置文件中
• 从应用程序的客户端和服务器部分引用它们

即把你的绑定(bind)放在 bindings.config :

<?xml version="1.0" encoding="utf-8"?>
<bindings>
  <basicHttpBinding>
    <binding name="Default" useDefaultWebProxy="false">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" 
                   proxyCredentialType="None" realm="" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>

然后从您服务的 app.config 或 web.config 中引用该文件:

<system.serviceModel>
    <bindings configSource="bindings.config" />
</system.serviceModel>

Visual Studio 会提示“configSource”——但相信我，它是有效的。这是用于验证的 Visual Studio XML 架构中的一个缺陷 - 但该功能有效。这实际上适用于您的 web.config/app.config 中的任何配置部分(但不适用于配置部分组)。

您可以对 <system.serviceModel> 的任何“小节”执行此操作配置组 - 客户端、服务器、行为、扩展，应有尽有。
