Question

我正在尝试将gzip压缩消息编码器从MS WCF samples包中删除到现有的WCF / WSDL应用程序（使用basicHttpBinding），但我遇到了应用配置问题。

我将GZipEncoder项目从示例添加到我的解决方案（包含GZipMessageEncoderFactory，GZipMessageEncodingBindingElement和GZipMessageEncodingBindingElementImporter），然后将扩展名添加到Web.config的serviceModel/extensions中（完整的最终web.config位于我的底部）问题）：

<bindingElementExtensions>
  <add name="gzipMessageEncoding" type="Microsoft.Samples.GZipEncoder.GZipMessageEncodingElement, GZipEncoder, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
</bindingElementExtensions>

..将gzipMessageEncoding添加到bindings/basicHttpBinding/binding部分：

<gzipMessageEncoding innerMessageEncoding="textMessageEncoding" />

解析器无法识别

gzipMessageEncoding，因此我将basicHttpBinding替换为serviceModel/bindings中的自定义：

<customBinding>
  <binding name="customBinding" closeTimeout="00:15:00" openTimeout="00:15:00" receiveTimeout="00:15:00" sendTimeout="00:15:00">
    <gzipMessageEncoding innerMessageEncoding="textMessageEncoding"/>
    <httpTransport hostNameComparisonMode="StrongWildcard" manualAddressing="False" maxReceivedMessageSize="2147483647" 
     authenticationScheme="Anonymous" bypassProxyOnLocal="False" realm="" useDefaultWebProxy="True" transferMode="Buffered"/>
  </binding>
</customBinding>

和serviceModel：

<protocolMapping>
  <add scheme="http" binding="customBinding" />
</protocolMapping>

然后在我的端点中命名为customBinding：

<service behaviorConfiguration="KiProjectsSyncServiceBehavior" name="KiProjectsSyncService">
  <endpoint address="" binding="customBinding" bindingConfiguration="KiProjectsSyncService" contract="IKiProjectsSyncService"/>

但是当我浏览服务时出现错误：

system.serviceModel / bindings / customBinding上的绑定没有有一个名为'KiProjectsSyncService'的配置绑定。这是个 bindingConfiguration的值无效。

我只想将gzip附加到basicHttp或其他一些简单的文本绑定。样本似乎是这样做的，但我看不出我偏离它的例子。理解这个配置会很棒，因为这个功能将来需要适应各种环境，我决定反对REST的原因之一就是这种架构的灵活性。

仅供参考：我希望双向压缩，我相信在IIS中打开压缩只会压缩下载。我的应用程序是两个IIS服务器ASP应用程序相互通信。我通过接口传输DataContract和MessageContract类型（后者用于在两个方向上传输文件，尽管实际上它们是在我使用BasicHttp时被缓冲的）。它运作良好 - 只是努力增加压缩。我还更改了客户端web.config（bindingElementExtensions，endPoint bindingConfig和binding，policyImporters和customBinding），但是在尝试浏览我的.svc服务时遇到这些问题，而不涉及客户端。

Answer 1

我错误的是endpoint bindingConfiguration必须设置为与绑定相同的值（在我的情况下，customBinding），即：

<services>
  <service behaviorConfiguration="KiProjectsSyncServiceBehavior" name="KiProjectsSyncService">
    <endpoint address="" binding="customBinding" bindingConfiguration="customBinding" contract="Kimetrica.Sync.IKiProjectsSyncService"/>
  </service>
</services>

我想象 bindingConfiguration设置可用于将新的自定义插入到WCF框架中。然后在客户端web.config中我必须添加以下内容：

  <system.serviceModel>
    <extensions>
      <bindingElementExtensions>
        <add name="gzipMessageEncoding" type="Kimetrica.Sync.GZipEncoder.GZipMessageEncodingElement, GZipEncoder, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
      </bindingElementExtensions>
    </extensions>
    <bindings>
      <customBinding>
        <binding name="customBinding" closeTimeout="00:15:00" openTimeout="00:15:00"
          receiveTimeout="00:15:00" sendTimeout="00:15:00">
          <gzipMessageEncoding innerMessageEncoding="textMessageEncoding" />
          <httpTransport manualAddressing="false" authenticationScheme="Anonymous"
            bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
            proxyAuthenticationScheme="Anonymous" realm="" useDefaultWebProxy="true" maxReceivedMessageSize="2147483647" transferMode="Buffered" />
        </binding>
      </customBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost:1062/WcfTestWebSite/KiProjectsSyncService.svc"
                binding="customBinding" bindingConfiguration="customBinding"
                contract="KiProjectsSyncServiceReference.IKiProjectsSyncService" name="KiProjectsSyncService" />
      <metadata>
        <policyImporters>
          <extension type="Microsoft.Samples.GZipEncoder.GZipMessageEncodingBindingElementImporter, GZipEncoder, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null"/>
        </policyImporters>
      </metadata>
    </client>
  </system.serviceModel>

这成功地添加了gzip压缩，并将包含FileStreams的DataContracts和MessageContracts（包括超过默认的64kb限制），IIS ASP应用程序发送到IIS ASP应用程序。

如何将gzip MessageEncoding bindingElementExtension添加到现有的WCF / WSDL应用程序？
