WCF错误 - 最大邮件大小配额传入消息（65536）已超过

Question

我的设置：在IIS快递

WCF服务托管

• ASP.NET客户端控制台应用程序托管
• 运行Visual Studio.NET 2012在管理模式

我想从WCF服务返回2个List对象。当我仅返回1个List对象时，我的设置WORKS FINE。但是，当我返回2列表对象时，出现错误：

传入消息的最大消息大小配额（65536）已被超出。要增加配额，请在适当的绑定元素上使用MaxReceivedMessageSize属性。

我知道这个问题已经在这个网站和其他网站上被询问了很多次。我已经尝试几乎所有发布在互联网上的配置文件的各种组合，但仍然没有为我工作。

那将是因为你没有它结合使用服务器上指定。我们来看看您的服务器配置：

根据<bindings>您正在创建<basicHttpBinding>的绑定配置，并且您将其命名为name="basicHttpBinding"。另外，您的端点名称为<endpoint name="basicHttpBinding" ...>，其绑定为binding="basicHttpBinding"。 但是，它不是指您的绑定配置，而是指绑定类型。所以，它实际上使用basicHttpBinding的默认设置。

要解决这个问题，首先要以不同的方式命名您的端点和绑定配置。例如，<endpoint name="basicEndpoint" ... >和<binding name="myBasicBinding" ... >。然后，您需要使用此属性将您的绑定配置分配给您的端点：bindingConfiguration="myBasicBinding"。

这里的客户端配置：

<system.web> 
    <httpRuntime maxRequestLength="32768"/> 
</system.web> 

<system.serviceModel> 
    <client> 
     <endpoint name="basicEndpoint" 
      address="http://localhost:9502/HCDataService" 
      binding="basicHttpBinding" 
      bindingConfiguration="myBasicBinding" 
      contract="HC.APP.Common.ServiceContract.IHCServiceContract" 
      behaviorConfiguration="ServiceBehaviour"> 
     </endpoint> 
    </client> 

    <bindings> 
     <basicHttpBinding> 
      <binding name="myBasicBinding" maxBufferSize="2147483647" maxBufferPoolSize="524288" maxReceivedMessageSize="2147483647"> 
       <readerQuotas maxDepth="128" maxStringContentLength="2147483647" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
      </binding> 
     </basicHttpBinding> 
    </bindings> 

    <behaviors> 
     <endpointBehaviors> 
      <behavior name="ServiceBehaviour"> 
       <dataContractSerializer maxItemsInObjectGraph="2147483647"/> 
      </behavior> 
     </endpointBehaviors> 
    </behaviors>  
</system.serviceModel> 

这里的服务器配置：

<system.serviceModel> 
    <services> 
     <service name="HC.APP.Server.Service.HCDataService" behaviorConfiguration="ServiceBehaviour"> 
      <host> 
       <baseAddresses> 
        <add baseAddress="http://localhost:9502/HCDataService"/> 
       </baseAddresses> 
      </host> 

      <endpoint name="basicEndpoint" 
       address="http://localhost:9502/HCDataService" 
       binding="basicHttpBinding" 
       bindingConfiguration="myBasicBinding" 
       contract="HC.APP.Common.ServiceContract.IHCServiceContract"> 
      </endpoint> 
     </service> 
    </services> 

    <bindings> 
     <basicHttpBinding> 
      <binding name="myBasicBinding" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" closeTimeout="01:50:00" openTimeout="01:50:00" sendTimeout="01:50:00" receiveTimeout="01:50:00" > 
       <readerQuotas maxDepth="128" maxStringContentLength="8388608" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> 
      </binding> 
     </basicHttpBinding> 
    </bindings> 

    <behaviors> 
     <serviceBehaviors> 
      <behavior name="ServiceBehaviour"> 
       <serviceDebug includeExceptionDetailInFaults="true" /> 
       <serviceMetadata httpGetEnabled="true" /> 
       <dataContractSerializer ignoreExtensionDataObject="false" maxItemsInObjectGraph="2147483646" /> 
      </behavior> 
     </serviceBehaviors> 
    </behaviors> 
</system.serviceModel> 

不要忘记update service reference您的客户端上，以得到正确的配置。
