WCF maxReceivedMessageSize未从配置中读取

Question

我有一个WCF服务的以下服务器端app.config:

  <system.serviceModel>
    <bindings>
      <wsHttpBinding>
        <binding name="default" maxReceivedMessageSize="5000000">
          <readerQuotas maxStringContentLength="5000000" maxArrayLength="5000000" />
        </binding>
      </wsHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="Core.TOAService.Service1Behavior"
        name="Core.TOAService.TOAService">
        <endpoint address="" binding="wsHttpBinding" contract="Core.TOAService.ITOAService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8732/Design_Time_Addresses/Core.TOAService/TOAService/" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="Core.TOAService.Service1Behavior">
          <!-- To avoid disclosing metadata information, 
          set the value below to false and remove the metadata endpoint above before deployment -->
          <serviceMetadata httpGetEnabled="True"/>
          <!-- To receive exception details in faults for debugging purposes, 
          set the value below to true.  Set to false before deployment 
          to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

当我尝试将此服务传递给一个较大的文件(仅约250KB)时,我在svclog文件中记录了一个异常:

已超出传入邮件的最大邮件大小限额(65536).要增加配额,请在相应的绑定元素上使用MaxReceivedMessageSize属性.

正如您从配置顶部的绑定部分所看到的,我已经尝试将maxReceivedMessageSize设置为5000000,但服务仍然认为它设置为默认值65536.任何想法是什么错误或哪个是"合适的"绑定元素？

还有更多设置:-)在<binding>标签上尝试"maxBufferPoolSize"和"maxBufferSize" .

但最大的问题是:您的端点没有引用该绑定配置!

<endpoint address="" 
          binding="wsHttpBinding" contract="Core.TOAService.ITOAService">

你需要添加一个引用,以便它变得有用 - 只是称它为"默认"不起作用.....

<endpoint address="" 
          binding="wsHttpBinding" 
          bindingConfiguration="default"
          contract="Core.TOAService.ITOAService">

你已经领先于你的时代;-)在WCF 4(使用.NET 4.0 - 2009年晚些时候的某个时间),你将能够定义"默认绑定配置"而无需明确命名和引用它们 - 但是现在,您需要在端点及其绑定和您拥有的任何绑定(或行为)配置之间创建链接!

如果您在使用WCF测试客户端时仍然收到此错误消息,那是因为客户端具有单独的MaxBufferSize设置.

要纠正此问题:

1. 右键单击树底部的" 配置文件"节点
2. 选择使用SvcConfigEditor编辑

将显示可编辑设置列表,包括MaxBufferSize.

注意: 默认情况下,自动生成的代理客户端还将MaxBufferSize设置为65536.
