WCF错误：远程服务器返回错误：（413）请求实体太大

Question

I created a WCF service to upload the 1MB file data into Windows Server. This web service is working fine with small file (950 KB) data but it has an issue with larger file size.

I tried several ways to fix it in WCF web.config but still stuck in above error. I need helps to setup on WCF configuration to resolve my issue.

Here are my web.config as following:

<system.serviceModel>
    <services>
      <service name="WCFService.UploadService">
        <endpoint address="REST" behaviorConfiguration="WCFServiceBehavior" binding="webHttpBinding" bindingConfiguration="WCFServiceBinding" contract="WCFService.IUploadService" />
      </service>
    </services>
    <bindings>
      <webHttpBinding>
        <binding name="WCFServiceBinding" maxReceivedMessageSize="1073741824" maxBufferSize="20971520" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" transferMode="Streamed">
          <security mode="Transport" />
        </binding>
      </webHttpBinding>
    </bindings>
    <behaviors>
      <endpointBehaviors>
        <behavior name="WCFServiceBehavior">
          <webHttp helpEnabled="true" automaticFormatSelectionEnabled="true" />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" minFreeMemoryPercentageToActivateService="0" />
  </system.serviceModel>

Kindly correct above WCF web.config

Please refer to the below configuration, it supports both Http and Https. You can cut it as needed. Besides, I use the ProtocolMapping feature to simplify my configuration.

<system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" name="httpbinding">
          <security mode="None">
          </security>
          <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147473647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>
        </binding>
        <binding name="httpsbinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
          <security mode="Transport">
            <transport clientCredentialType="None"></transport>
          </security>
          <readerQuotas maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="2147473647" maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/>
        </binding>
      </webHttpBinding>
    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior>
          <webHttp />
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <protocolMapping>
      <!--http and https are all supported.-->
      <add binding="webHttpBinding" scheme="http" bindingConfiguration="httpbinding"/>
      <add binding="webHttpBinding" scheme="https" bindingConfiguration="httpsbinding"/>
    </protocolMapping>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
