我即将将应用程序移植到silverlight。到目前为止,我的客户端应用程序使用 netTcpBinding 与服务器通信。但是 Silverlight 不支持这一点,我发现他们建议改用自定义绑定。

我想知道我是否需要以关于安全性的特殊方式配置绑定。当客户端和服务器在同一台机器上运行但在不同机器上运行时,我的分布式应用程序运行良好。在这种情况下,我收到以下错误:

由于 EndpointDispatcher 的 ContractFilter 不匹配,接收方无法处理带有操作“ http://schemas.xmlsoap.org/ws/2005/02/rm/CreateSequence ”的消息。这可能是由于合同不匹配(发送方和接收方之间的操作不匹配)或发送方和接收方之间的绑定/安全不匹配。检查发送方和接收方是否具有相同的合同和相同的绑定(包括安全要求,例如消息、传输、无)。

我已经检查了合同和绑定(当切换到自定义绑定时会出现问题,而 netTcpBinding 可以正常工作)。该端口也在防火墙处启用。根据错误消息,我认为 WCF 可能假设了一些在客户端和服务器中不匹配的安全默认值。

服务器配置文件如下:

<?xml version="1.0"?>
<configuration>
  <system.serviceModel>
    <services>
      <service behaviorConfiguration="MetaEnabledBehavior" name="MyService">
        <host>
          <baseAddresses>
            <add baseAddress="http://MyIP:Port#/MyService"/>
          </baseAddresses>
        </host>

        <endpoint address="custom"
                  binding="customBinding"
                  contract="MyService"
                  bindingConfiguration="binaryHttpBinding"                   
                  />
      </service>
    </services>
    <bindings>

      <customBinding>
        <binding name="binaryHttpBinding">
          <binaryMessageEncoding />          
          <reliableSession ordered="true" inactivityTimeout="01:00:00"/>
          <httpTransport />
        </binding>
      </customBinding>

    </bindings>
    <behaviors>
      <serviceBehaviors>
        <behavior name="MetaEnabledBehavior">
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v2.0.50727"/>
  </startup>
</configuration>

客户端配置是这样的:


<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.serviceModel>
    <bindings>

      <customBinding>
        <binding name="default_binding">

          <reliableSession ordered ="true" inactivityTimeout="01:00:00"/>
          <binaryMessageEncoding maxReadPoolSize="64" 
                                 maxWritePoolSize="16"
                                 maxSessionSize="2048">
            <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384"
                maxBytesPerRead="4096" maxNameTableCharCount="16384" />          

          </binaryMessageEncoding>
          <httpTransport manualAddressing="false" maxBufferPoolSize="524288"
              maxReceivedMessageSize="65536" allowCookies="false" authenticationScheme="Anonymous"
              bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard"
              keepAliveEnabled="true" maxBufferSize="65536" proxyAuthenticationScheme="Anonymous"
              realm="" transferMode="Buffered" unsafeConnectionNtlmAuthentication="false"
              useDefaultWebProxy="true" />
        </binding>
      </customBinding>

    </bindings>
    <client>

      <endpoint address="http://MyIP:Port#/MyService/custom"
                binding ="customBinding"
                contract="MyService"
                bindingConfiguration = "default_binding"
                name="default_binding" />

    </client>
  </system.serviceModel>
</configuration>
