WCF 错误 - (413) 请求实体太大

Question

我有 2 个 WCF 服务一起工作。一种是类库，另一种是Web服务。

到目前为止它运行良好。但如果我尝试发送大量数据，它会抛出 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"

行为配置=“webBehaviour”/>

对于网络服务客户端-

<?xml version="1.0"?>
<configuration>
  <!-- 
      Note: As an alternative to hand editing this file you can use the 
      web admin tool to configure settings for your application. Use
      the Website->Asp.Net Configuration option in Visual Studio.
      A full list of settings and comments can be found in 
      machine.config.comments usually located in 
      \Windows\Microsoft.Net\Framework\vx.x\Config 
  -->
  <configSections>

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

---------------------- --> 部分允许配置 ASP.NET 用于识别传入用户的安全身份验证模式。--> 部分允许配置如果/当在请求执行期间发生未处理的错误时要执行的操作。具体来说，它使开发人员能够配置要显示的 html 错误页面来代替错误堆栈跟踪。

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
         <error statusCode="403" redirect="NoAccess.htm" />
         <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>
    -->

      </service>
    </services>
    <behaviors>
      <serviceBehaviors>

          <!-- 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

您遇到了 WCF 对消息大小的默认限制。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>
