wcf Request Entity Too Large 错误

今天试着使用wcf上传文件，大小为2.4MB就报错了，报Request Entity Too Large错误。

修改配置文件，增加bindings设置，修改binding 的maxReceivedMessageSize设置，如下所示

<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<!-- 为避免泄漏元数据信息，请在部署前将以下值设置为 false -->
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<!-- 要接收故障异常详细信息以进行调试，请将以下值设置为 true。在部署前设置为 false 以避免泄漏异常信息 -->
<serviceDebug includeExceptionDetailInFaults="false"/>
</behavior>
</serviceBehaviors>
</behaviors>
<bindings>
<basicHttpBinding>
<binding closeTimeout="00:10:00" receiveTimeout="00:20:00" sendTimeout="00:20:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
</basicHttpBinding>
</bindings>
<protocolMapping>
<add binding="basicHttpBinding" scheme="http" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
</system.serviceModel>
