WCF maxReceivedMessageSize不能设置超过4215

我想在WCF客户端的App.config中设置maxReceivedMessageSize。

如果maxReceivedMessageSize等于或小于4215则可以正常工作。虽然将其设置为4216或高于它的任何值,但默认值为65536。

我的客户代码

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IConexaApiServic" maxReceivedMessageSize="4216" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://svsr02.conexa.local/HelloService/ConexaApiService.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IConexaApiServic"
                contract="ConexaApiService.IConexaApiService" name="BasicHttpBinding_IConexaApiService" />
        </client> 
    </system.serviceModel>
</configuration>

相关服务器代码

<basicHttpBinding>
        <binding name="BasicHttpEndpoint_MPSAPIServic" maxReceivedMessageSize="2000000">
          <security mode="TransportWithMessageCredential" />
        </binding>
        <binding name="BasicHttpEndpoint_HelloService" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxReceivedMessageSize="2000000">

  </binding>
   </basicHttpBinding>

 <service name="IIS_test123.HelloService">
        <endpoint address="ConexaApi" binding="basicHttpBinding" bindingConfiguration="BasicHttpEndpoint_HelloService" contract="IIS_test123.IHelloService"></endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8733/API/ConexaApiService" />
          </baseAddresses>
        </host>
      </service>
    </services>

知道如何解决这个问题吗?

这可以解释。如果你看看你的例外:

  • System.ServiceModel.CommunicationException是从客户端抛出的异常。它具有来自客户端的maxReceivedMessageSize。一切都很好。
  • FaultException:此异常是一个SOAP错误,它将异常从服务传播到客户端应用程序。 (http://www.codeproject.com/Articles/799258/WCF-Exception-FaultException-FaultContract)。所以这个例外实际上来自服务方面! maxReceivedMessageSize是默认值,与服务器配置中的maxReceivedMessageSize不对应。 您在客户端中连接的地址是服务地址,未配置maxReceivedMessageSize,而不是使用maxReceivedMessageSize =&#34; 2000000&#34;配置的端点地址ConexaApi。那&#39;为什么你得到默认的65536。

如果您认为如果增加例外情况不会引发异常,那么4215必须是您邮件的大小。
