WCF入门教程（VS2008 + IIS）

最近一个项目需要使用WCF，参考了很多网上资料和MSDN，总结如下：

1：建立一个IIS作为HOST的WCF工程

     选择NEW Project,然后选择C#，然后选择WEB，然后选择WCF Service Application

    VS2008将自动帮你生成一个示例项目，只需要在它基础上修改就可以。

2：修改WEB.CONFIG文件

    如果你想在不同的机器访问WCF服务，需要设置身份验证，最简单是设置为None。如下：

   <system.serviceModel>
   
  <services>
   <service behaviorConfiguration="WCFService.WCFServiceBehavior" name="WCFService.WCFService">
    <endpoint address="http://localhost:9000/wcfservice" binding="wsHttpBinding" bindingConfiguration="WCFBindConfig"  contract="WCFService.IWCFService">
     <identity>
      <dns value="localhost"/>
     </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
   </service>
  </services>
   
  <behaviors>
   <serviceBehaviors>
    <behavior name="WCFService.WCFServiceBehavior">
     <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
     <serviceMetadata httpGetEnabled="true"/>
     <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
     <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
   </serviceBehaviors>
  </behaviors>
    <!--
    using System.IdentityModel
    -->
    <bindings>
      <wsHttpBinding>
        <binding name ="WCFBindConfig">
          <security mode ="None">
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
   
 </system.serviceModel>

3:然后客户端也相应的设置为None就可以访问，这里需要特别注意的就是：

    <bindings>
      <wsHttpBinding>
        <binding name ="WCFBindConfig">
          <security mode ="None">
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>

和上面的一行

      <endpoint address="http://localhost:9000/wcfservice" binding="wsHttpBinding" bindingConfiguration="WCFBindConfig"  contract="WCFService.IWCFService">

4：如果想使用用户名密码验证，WEB.CONFIG配置如下：

 

 <system.serviceModel>
   
  <services>
   <service behaviorConfiguration="WCFService.WCFServiceBehavior" name="WCFService.WCFService">
    <endpoint address="http://localhost:9000/wcfservice" binding="wsHttpBinding" bindingConfiguration="WCFBindConfig"  contract="WCFService.IWCFService">
     <identity>
      <dns value="localhost"/>
     </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
   </service>
  </services>
   
  <behaviors>
   <serviceBehaviors>
    <behavior name="WCFService.WCFServiceBehavior">
     <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
     <serviceMetadata httpGetEnabled="true"/>
     <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
     <serviceDebug includeExceptionDetailInFaults="false"/>
          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode ="Custom"  customUserNamePasswordValidatorType="WCFService.WCFService+MyUserNamePasswordValidator,WCFService"/>
          </serviceCredentials>
    </behavior>
   </serviceBehaviors>
  </behaviors>
    <!--
    using System.IdentityModel
    -->
    <bindings>
      <wsHttpBinding>
        <binding name ="WCFBindConfig">
          <security mode ="Message">
            <message clientCredentialType ="Windows" establishSecurityContext ="false"/>
          </security>
        </binding>
      </wsHttpBinding>
    </bindings>
   
 </system.serviceModel>

  需要注意的如下：

<serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode ="Custom"  customUserNamePasswordValidatorType="WCFService.WCFService+MyUserNamePasswordValidator,WCFService"/>
          </serviceCredentials>

MyUserNamePasswordValidator是自己定义的一个验证类，必须从UserNamePasswordValidator继承。

WCFService是你的程序集名称，也就是工程名。

 WCFService.WCFService是你的namespace.
