WCF错误 - 已超出传入邮件的最大邮件大小限额(65536)

Question

我的设置:

• IIS客户端托管的ASP.NET客户端
• 控制台应用程序中托管的WCF服务
• 在管理员模式下运行Visual Studio.NET 2012

我试图从WCF服务返回2个List对象.当我只返回1个List对象时,我的设置工作很精细.但是当我返回2个List对象时,我收到错误:

已超出传入邮件的最大邮件大小限额(65536).要增加配额,请在相应的绑定元素上使用MaxReceivedMessageSize属性.

我知道这个问题在本网站和其他网站上也被多次询问过.我已尝试使用CONFIG FILE的各种组合在互联网上发布的几乎所有内容,但这对我来说仍然没有成功.

那是因为你没有在服务器上指定使用哪种绑定.我们来看看你的服务器配置:

在<bindings>您创建一个绑定配置<basicHttpBinding>,并且您命名它name="basicHttpBinding".此外,您的端点名称是<endpoint name="basicHttpBinding" ...>,其绑定是binding="basicHttpBinding".但是,它不是指您的绑定配置,而是指绑定类型.所以,它实际上是使用默认设置basicHttpBinding.

要解决此问题,首先要以不同方式命名端点和绑定配置.例如,<endpoint name="basicEndpoint" ... >和<binding name="myBasicBinding" ... >.然后,您需要使用以下属性将绑定配置分配给端点:bindingConfiguration="myBasicBinding".

这是客户端配置:

<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>

这是服务器配置:

<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在客户端上获取正确的配置.
