如何使用EF 6为WCF数据服务(odata)设置配置文件

Question

我有一个数据服务启动并运行,但我收到此错误:

远程服务器返回错误:(413)请求实体太大.

我已经尝试过许多方法来解决这个问题而没有运气.我已将网站上的uploadReadAheadSize和IIS中的数据服务设置为最大设置.我还为配置文件尝试了许多不同的设置.

这是客户端的当前app.config:

  <system.serviceModel>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_ILogging" />
    <binding name="WCFHttpBinding"
             maxReceivedMessageSize="2147483647"
             maxBufferSize="2147483647"
             maxBufferPoolSize="2147483647">
      <readerQuotas maxArrayLength="2147483647"
                    maxDepth="2147483647"
                    maxBytesPerRead="2147483647"
                    maxNameTableCharCount="2147483647"
                    maxStringContentLength="2147483647"/>
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding name="WCFWebBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
    </binding>
  </webHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost/PSIDataService/PSIWcfDataService.svc"
            binding="webHttpBinding" bindingConfiguration="WCFWebBinding"
            name="WCFWebBinding" contract="*"/>
</client>

我尝试了两种绑定,WCFWebBinding和WCFHttpBinding.

这是web服务web.config.

  <system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="">
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <basicHttpBinding>
    <binding name="WCFHttpBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" messageEncoding="Text">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding name="WCFWebBinding" maxBufferPoolSize="2147483647" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647"/>
    </binding>
  </webHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost/PSIDataService/PSIWcfDataService.svc"
      binding="basicHttpBinding"
      bindingConfiguration="WCFHttpBinding"
      name="WCFHttpBinding"
      contract="*"/>

</client>

再次,我尝试了两种绑定.我不知道还能做些什么.任何帮助都会很棒.

我找到了解决这个问题的方法.web.config必须添加一个服务命​​名服务,并将合同设置为"System.Data.Services.IRequestHandler"

<system.serviceModel>
<services>
  <service name="PSIDataService.PSIWcfDataService">
    <endpoint bindingConfiguration="msgSize" 
              address="" 
              binding="webHttpBinding" 
              contract="System.Data.Services.IRequestHandler"/>
  </service>
</services>

我的系统抱怨服务名称和合同(属性是无效警告).我的服务的命名空间是PSIDataService,类名是PSIWcfDataService,所以我忽略了投诉.合同名称具有相同的警告.我知道界面存在,所以我也忽略了这个警告.

还需要webHttpBinding.

  <bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_ILogging" />
  </basicHttpBinding>
  <webHttpBinding>
    <binding name="msgSize" maxReceivedMessageSize="2147483647" maxBufferSize="2147483647"/>
  </webHttpBinding>
</bindings>

我从Malvin Ly得到了这个修复的想法(malvinly.com/2011/05/09/wcf-data-services-and-maxreceivedmessagesize)所以感谢Malvin!我不喜欢警告,但这解决了我的问题.
