Question

从我的Silverlight 4项目中，我调用了一个WCF服务，该服务可以通过包装器服务访问。这只是一个WCF服务应用程序，其中包含对我的其他WCF的服务引用。我得到以下例外：

“传入邮件的最大邮件大小限额（65536）已经过超标。要增加配额，请使用MaxReceivedMessageSize 适当的绑定元素上的属性。“。

调试时我看到：

ProtocolException未被用户代码处理 - 远程服务器返回了意外的回复：（400）错误请求。

在Silverlight中，即使服务发送不同的错误代码，也可能会报告404响应代码。

我正在使用Silverlight 4＆amp; .NET 4.0。

我可以更改maxBufferSize＆amp; WCF测试客户端中的maxReceivedMessageSize为524288，以查看我的预期结果。

如何更改这些值以便实际使用它们而不是WCF默认设置？

Wrapper Service web.config：

<?xml version="1.0"?>

      <basicHttpBinding>

          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://internal:51505/SvcApp/MySvc_MyService.svc"
          binding="basicHttpBinding"
          bindingConfiguration="BasicHttpBinding_IMyService"
          contract="WCFServiceRef.IMyService"
          name="BasicHttpBinding_IMyService" />
    </client>

Web项目web.config：

<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding name="BasicHttpsBinding_IMyWrapperService" maxBufferSize="524288"
       maxReceivedMessageSize="524288">

      </binding>

         maxBytesPerRead="524288" maxNameTableCharCount="524288" />
        <security mode="None">
          <transport clientCredentialType="None" proxyCredentialType="None"
           realm="" />
          <message clientCredentialType="UserName" algorithmSuite="Default" />
        </security>
      </binding>
    </basicHttpBinding>
  </bindings>
  <client>
    <endpoint address="http://internal/mysvc/MyWrapperService.svc"
              binding="basicHttpBinding"
              bindingConfiguration="BasicHttpBinding_IMyWrapperService"
              contract="WrapperServiceServiceRef.IMyWrapperService"
              name="BasicHttpBinding_IMyWrapperService" />
  </client>
</system.serviceModel>

我已经看到了为serviceBehavior命名并添加maxItemsInObjectGraph的建议。

我尝试添加“LargeEndpointBehavior”，但这似乎没有做任何事情。

<client>
  <endpoint address="http://internal:51505/SvcApp/MySvc_MyService.svc"
      binding="basicHttpBinding"
      bindingConfiguration="BasicHttpBinding_IMyService"
      contract="WCFServiceRef.IMyService"
      name="BasicHttpBinding_IMyService"
      behaviorConfiguration="LargeEndpointBehavior" />
</client>

<behaviors>
  <serviceBehaviors>
    <behavior name="LargeEndpointBehavior">
      <serviceMetadata httpGetEnabled="true"/>
      <serviceDebug includeExceptionDetailInFaults="true"/>
      <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
    </behavior>
  </serviceBehaviors>
</behaviors>

我只需要修复我的服务包装器web.config吗？

我通过包装器调用的服务，我的Silverlight项目中的ServiceReferences.ClientConfig＆amp;托管我的xap文件的Web应用程序的所有值都已超出。

有什么建议吗？

如何更改maxBufferSize＆amp; WCF Wrapper服务中的maxReceivedMessageSize？
