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

我正试图将gzip压缩消息编码器从包中放入现有的WCF/WSDL应用程序（使用

basicHttpBinding

），但应用程序配置有问题

我将GZipEncoder项目从示例添加到解决方案中（包含GZipMessageEncoderFactory、GZipMessageEncodingBindingElement和GZipMessageEncodingBindingElementImporter），然后将扩展添加到Web.config的

serviceModel/extensions

（完整的最终Web.config位于我问题的底部）：

解析器无法识别

gzimpessageencoding

，因此我在

serviceModel/bindings

中将basicHttpBinding替换为自定义绑定：

<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>

然后在我的端点中将customBinding命名为：

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

但是，当我浏览到该服务时，会出现错误：

system.serviceModel/bindings/customBinding上的绑定不可用 已配置名为“KiProjectsSyncService”的绑定。这是一个 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。这个示例似乎做到了这一点，但我看不出我在哪里偏离了它的示例。理解这个配置会很好，因为这个功能将来需要适应各种环境，我决定不使用REST的原因之一就是这个架构的灵活性

仅供参考：我想要双向压缩，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相互通信的IIS服务器ASP应用程序。我通过接口传输DataContract和MessageContract类型（后者用于双向流文件，尽管在我使用BasicHttp时它们实际上是缓冲的）。这一切都很好-只是努力增加压缩。我还修改了客户机web.config（bindingElementExtensions、endPoint bindingConfig和binding、policyImporters和customBinding），但我只是试图浏览到我的.svc服务，而不涉及客户机

我唯一的错误是，

端点

绑定配置

必须设置为与绑定相同的值（在我的情况下，

customBinding

），即：

我认为bindingConfiguration设置可以用于向WCF框架插入新的定制。然后在client 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，并将包含文件流的DataContracts和MessageContracts（包括超过默认64kb的限制）、IIS ASP应用程序发送到IIS ASP应用程序。

我想我已经修复了它（现在正在处理客户端配置）。在

端点

中，

绑定配置

必须与

绑定

相同，即

自定义绑定

。服务现在似乎出现在浏览器中，但尚未与客户端连接。当我把这个发出去的时候，我会发帖的。
