我有 2 个 WCF 服务一起工作。一个是类库，另一个是 web 服务。

直到现在它工作正常。但是，如果我尝试发送大量数据，则会引发 413 错误...

An exception was thrown: The remote server returned an error: (413) Request Entity Too Large.

下面是 web.config 文件-

对于类库-

    <add key="SMTP" value ="dummy"/>
    <add key="BookingEmailFrom" value ="dummy"/>
    <add key="BookingEmailToWBD" value ="dummy"/>

  </appSettings>
  <connectionStrings/>
  <system.web>
    <compilation debug="true" targetFramework="4.0"/>
    <!--
        The <authentication> section enables configuration 
        of the security authentication mode used by 
        ASP.NET to identify an incoming user. 
    -->
    <authentication mode="Windows"/>
    <!--
        The <customErrors> section enables configuration 
        of what to do if/when an unhandled error occurs 
        during the execution of a request. Specifically, 
        it enables developers to configure html error pages 
        to be displayed in place of a error stack trace.

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
         <error statusCode="403" redirect="NoAccess.htm" />
         <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>
    -->
    <pages controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID"/>
  </system.web>
  <!-- 
      The system.webServer section is required for running ASP.NET AJAX under Internet
      Information Services 7.0.  It is not necessary for previous version of IIS.
  -->
  <system.serviceModel>
    <services>
      <service name="JSONWebService.Service1" behaviorConfiguration="JSONWebService.Service1Behavior">
        <endpoint address="../Service1.svc" binding="webHttpBinding" contract="JSONWebService.IService1"

behaviorConfiguration="webBehaviour"/>

对于 Web 服务客户端 -

<?xml version="1.0"?>
<configuration>
  <!--

      web admin tool to configure settings for your application. Use

      machine.config.comments usually located in

  <configSections>

  </configSections>
  <appSettings>
    <add key="ConnectionString" value="Server=dummy;uid=sa;pwd=dummy;database=dummy"/>

      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior" >
          <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before

    </bindings>


  </system.serviceModel>



</configuration>

任何帮助将非常感激。

谢谢

您遇到消息大小的 WCF 默认限制。要提高限制，请使用 web.config 文件（服务器端）中的 maxReceivedMessageSize 属性。 

<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding maxReceivedMessageSize="10000000">
    </basicHttpBinding>
  </bindings>
</system.serviceModel>

这可能真的很晚了，但对于其他也被卡住的人来说。

最初的问题由 BilalAlam 描述的内容（增加 maxRecievedMessageSize）解决，但您的问题是绑定需要通过端点中的bindingConfiguration和绑定中的名称绑定到端点。

例子

<bindings>
  <webHttpBinding>
    <binding maxReceivedMessageSize="2147483647" name="NAMETOTIEENDPOINT">
      <readerQuotas maxStringContentLength="2000000"/>
    </binding>
  </webHttpBinding>
</bindings>
<services>
  <service>
    <endpoint address="basic" bindingConfiguration="NAMETOTIEENDPOINT" binding="webHttpBinding" contract="JSONWebService.IService1"  />
  </service>
</services>
