WCF (413) Request Entity Too Large 需要配置上传文件大小

Error消息：

　　System.Net.WebException: The remote server returned an error: (413) Request Entity Too Large.

解决办法

　　修改请求端的配置文件，单位是KB，在<system.web></system.web>：

<httpRuntime executionTimeout="600" maxRequestLength="20480" />

maxRequestLength=20480表示最大上传文件的大小限制在20M以内。

<system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="BasicHttpBinding_IDEMOFrontendService" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true" messageEncoding="Text">

          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
            <message clientCredentialType="UserName" algorithmSuite="Default" />
          </security>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint address="http://localhost/DEMOFrontend/DEMOFrontendService.svc" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IDEMOFrontendService" contract="DEMOFrontendServiceReference.IDEMOFrontendService" name="BasicHttpBinding_IDEMOFrontendService" />
    </client>
  </system.serviceModel>

　　修改WCF配置文件，在<system.serviceModel></system.serviceModel>：

<bindings>
      <basicHttpBinding>
        <binding name="DemoHttpBinding_CheckAccess" closeTimeout="00:50:00" openTimeout="00:50:00" receiveTimeout="00:50:00" sendTimeout="00:50:00"
          maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" >
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <security mode="None">
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
            <message clientCredentialType="UserName" algorithmSuite="Default"/>
          </security>
        </binding>
      </basicHttpBinding>
      <basicHttpsBinding>
        <binding name="DEMOHttpsBinding_GetwayService" closeTimeout="00:50:00" openTimeout="00:50:00" receiveTimeout="00:50:00" sendTimeout="00:50:00"
                    maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" >
          <readerQuotas maxDepth="32" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
            <message clientCredentialType="UserName" algorithmSuite="Default"/>
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>

    <protocolMapping>
        <add binding ="basicHttpsBinding" scheme="https" bindingConfiguration="DEMOHttpsBinding_GetwayService" />
        <add binding ="basicHttpBinding" scheme="http" bindingConfiguration="DemoHttpBinding_CheckAccess"/>
    </protocolMapping>
