WCF 最大消息大小错误

Question

我已经为 IStudent 实现了 WCF 服务，其中很少有人会超出传入消息的最大消息大小配额 (65536)。我已经实现了 wsHttpBinding，我也尝试在绑定选项卡下增加消息端，但仍然出现错误，还绑定 maxBufferSize=""... 如果它假设是，则无法识别

最初我在 WCF 测试客户端工具上测试我的服务

App.config

<service name="App.WebServices.Manager.EBSMiddlewareServicesManager" behaviorConfiguration="EBSMiddlewareBehaviorDefault">
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:30432/"/>
      </baseAddresses>
    </host>
    <endpoint name="StudentServices" address="StudentServices" binding="wsHttpBinding" contract="App.WebServices.ServiceContract.IStudentServices"/>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
  </service>
</services>

....

<bindings>
  <wsHttpBinding>
    <binding name="DefaultTransportSecurity" sendTimeout="00:10:00" allowCookies="true" maxReceivedMessageSize="2147483647" maxBufferSize="" maxBufferPoolSize="2147483647">
      <security mode="Transport">
        <transport clientCredentialType="None"/>
      </security>
      <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" />
    </binding>
  </wsHttpBinding>
</bindings>

错误

The maximum message size quota for incoming messages (65536) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.

Answer 1

绑定的MaxReceivedMessageSize 属性是下面错误中超出的值。您需要覆盖该值。您可能还想测试已应用于 readerQuotas 的值。

<wsHttpBinding>
    <binding 
         name="myBinding" 
         maxReceivedMessageSize="2147483647"
     </binding>
</wsHttpBinding>

Answer 2

我找到了原因，我更新的 app.config 是用于服务器端的，我正在使用 WCF 测试客户端工具来测试我的服务，所以我也需要增加工具端的大小

添加服务，请注意在服务树的末尾有一个“配置文件”节点：右键单击它并选择“使用 SvcConfigEditor 编辑”，获取服务端的确切配置编辑器 - 只需转到绑定设置并更改 MaxReceivedMessageSize 并保存更改。
