由于参数大小导致 WCF 服务通信异常

Question

我有一个 WCF Web 方法，它将 XElement 对象作为参数。对于我的一个 XML 文件(大小为 600KB 左右)，这工作得很好，但是，对于这个更大的 XML 文件(大约 5MB)，我立即得到一个 CommunicationException。

我已经增加了绑定(bind)的消息大小。下面是我的 web.config 的 ServiceModel 部分:

<system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="BIMIntegrationWS.metadataBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
    <behavior name="">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>        

<bindings>
  <customBinding>        
    <binding name="BIMIntegrationWS.IntegrationService.customBinding0"
      closeTimeout="00:01:00" openTimeout="00:01:00"
      receiveTimeout="00:10:00" sendTimeout="00:10:00">
      <binaryMessageEncoding>
        <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647"
                        maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
      </binaryMessageEncoding>
      <httpTransport  maxBufferPoolSize="2147483647"   maxBufferSize="2147483647"
                      maxReceivedMessageSize="2147483647" />
    </binding>
  </customBinding>
</bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
<services>      
  <service name="BIMIntegrationWS.BIMIntegrationWS" behaviorConfiguration="BIMIntegrationWS.metadataBehavior">
    <endpoint address="" binding="customBinding" bindingConfiguration="BIMIntegrationWS.IntegrationService.customBinding0"
     contract="BIMIntegrationWS.IBIMIntegrationService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
</system.serviceModel>

在客户端，我的 ClientConfig 如下所示:

<system.serviceModel>      
      <bindings>
            <customBinding>                
                  <binding name="CustomBinding_IBIMIntegrationService">
                    <binaryMessageEncoding />
                    <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />                                       
                  </binding>
            </customBinding>
      </bindings>        
    <client>          
        <endpoint address="http://localhost:1895/IntegrationService.svc"
            binding="customBinding" bindingConfiguration="CustomBinding_IBIMIntegrationService"
            contract="BIMIntegrationService.IBIMIntegrationService" name="customBindingEndpoint" />
    </client>
</system.serviceModel>

提前致谢!

尝试将以下代码段添加到服务应用程序的 web.config 中:

  <system.web>
    <httpRuntime maxRequestLength="16384" /> <!-- 16MB -->
  </system.web>

当您在 Web 服务器中托管服务时，您还必须调整 Web 服务器允许的请求大小。
