WCF服務接受GZip消息

Question

我可能錯過了明顯的，但我怎麼能使它，以便我的WCF服務上的一個方法，PutMessage，可以接受GZip'd和正常請求？現在，我從我的服務看到此錯誤：

Cannot process the message because the content type 'application/gzip' was not the expected type 'text/xml; charset=utf-8'. 

我已經嘗試添加自定義與binaryMessageCoding/compressionFormat =「壓縮」和httpTransport結合。這是否需要配置多個綁定和多個端點？還是多個綁定和一個端點？一個端點和一個綁定？

我無法更改發送代碼，因爲它是我無權訪問的第三方。

這是到目前爲止我的web.config：

<system.serviceModel> 
    <behaviors> 
     <serviceBehaviors> 
     <behavior name="UserNameAuthenticationBehaviour"> 
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> 
      <serviceDebug includeExceptionDetailInFaults="true" /> 
      <serviceCredentials> 
      <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="API.Star.XXXUsernamePasswordValidator, API" /> 
      </serviceCredentials> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    <bindings> 
     <basicHttpBinding> 
     <binding name="API.Star.starTransport"> 
      <security mode="TransportWithMessageCredential"> 
      <transport clientCredentialType="Basic" /> 
      <message clientCredentialType="UserName" /> 
      </security> 
     </binding> 
     </basicHttpBinding> 
     <customBinding> 
     <binding name="API.Star.starTransportGzip"> 
      <binaryMessageEncoding compressionFormat="GZip" /> 
      <httpTransport /> 
     </binding> 
     </customBinding> 
    </bindings> 
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> 
    <services> 
     <service name="API.Star.StarWebService" behaviorConfiguration="UserNameAuthenticationBehaviour"> 
     <endpoint name="StarWebServiceEndpoint" address="" binding="basicHttpBinding" bindingConfiguration="API.Star.starTransport" contract="API.Star.operations" bindingNamespace="http://www.starstandards.org/webservices/2005/10/transport" /> 
     <endpoint name="StarWebServiceEndpointGzip" address="" binding="customBinding" bindingConfiguration="API.Star.starTransportGzip" contract="API.Star.operations" bindingNamespace="http://www.starstandards.org/webservices/2005/10/transport" /> 
     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     </service> 
    </services> 
    </system.serviceModel>

當你在IIS託管服務，您不需要做任何特殊的.NET 4+。您只需在IIS上啓用HTTP壓縮。

查看What's New in WCF 4中關於Http Decompression的部分，瞭解關於如何使用enable HTTP compression in IIS 7的一些鏈接。

在WCF 4.5中，您也可以獲得對二進制編碼器的壓縮支持。檢查部分Compression and the Binary Encoder
