WCF通信错误-Java 学习之路

我们几天来一直遇到WCF通信错误，我无法弄清楚导致错误的原因 . 我原本以为这是一个SSL证书问题，但事实并非如此 . 我还确保只需在Web浏览器上输入URL即可访问 endpoints ，并且可以查看 endpoints . 我还确保默认请求大小不会导致问题 . 我确定请求的默认值小于30MB .

还有什么能阻止这种堆栈跟踪错误？

客户端堆栈跟踪：

由于通信失败，WCFDirector提取失败 . 由于表格没有正确加载，因此必须关闭 . ---> OSI.Framework.FrameworkException：由于通信失败，WCFDirector提取失败 . ---> System.ServiceModel.CommunicationException：底层连接已关闭：服务器已关闭预期保持活动状态的连接 . ---> System.Net.WebException：底层连接已关闭：服务器已关闭预期保持活动状态的连接 . ---> System.IO.IOException：无法从传输连接读取数据：远程主机强制关闭现有连接 . ---> System.Net.Sockets.SocketException：远程主机在System的System.Net.Sockets.Socket.Receive（Byte []缓冲区，Int32偏移量，Int32大小，SocketFlags socketFlags）强制关闭现有连接 . Net.Sockets.NetworkStream.Read（Byte []缓冲区，Int32偏移量，Int32大小）---内部异常堆栈跟踪结束---在System.Net.Sockets.NetworkStream.Read（Byte []缓冲区，Int32偏移量，在系统上的System.Net.FixedSizeReader.ReadPacket（Byte []缓冲区，Int32偏移量，Int32计数）处的System32.Net.Security._SslStream.StartFrameHeader（Byte []缓冲区，Int32偏移量，Int32计数，AsyncProtocolRequest asyncRequest）处的Int32大小）系统中的System.Net.Security._SslStream.ProcessRead（Byte []缓冲区，Int32偏移量，Int32计数，AsyncProtocolRequest asyncRequest）的.Net.Security._SslStream.StartReading（Byte []缓冲区，Int32偏移量，Int32计数，AsyncProtocolRequest asyncRequest） System.Net.PooledStream.Read（Byte []缓冲区，Int32偏移量的.Net.TlsStream.Read（Byte []缓冲区，Int32偏移量，Int32大小） System.Net.Connection.SyncRead上的，Int32大小）（HttpWebRequest请求，布尔userRetrievedStream，布尔探测器读取）---内部异常堆栈跟踪的结束---在System.ServiceModel.Channels的System.Net.HttpWebRequest.GetResponse（）处.HttpChannelFactory`1.HttpRequestChannel.HttpChannelRequest.WaitForReply（TimeSpan timeout）---内部异常堆栈跟踪结束---

服务器堆栈跟踪：

System.ServiceModel.Channels.HttpChannelUtilities.ProcessGetResponseWebException（WebException webException，HttpWebRequest请求，HttpAbortReason abortReason），位于System.ServiceModel.Channels.RequestChannel的System.ServiceModel.Channels.HttpChannelFactory`1.HttpRequestChannel.HttpChannelRequest.WaitForReply（TimeSpan timeout） .

尝试关闭KeepAlive . 就像是：

var client = new MyWcfClient();
var customBinding = new CustomBinding(client.Endpoint.Binding);
var transportElement = customBinding.Elements.Find<HttpTransportBindingElement>();

transportElement.KeepAliveEnabled = false;

client.Endpoint.Binding = customBinding;

仅配置Rest API和SOAP的版本

<services>
  <service name="SecureTransportDemo.Service.GreetingService">
    <endpoint address="Soap"
              binding="customBinding" 
              bindingConfiguration="soap-secure-nokeepalive"
              contract="SecureTransportDemo.Service.IGreetingService"
              name="soap-nokeepalive"/>
    <endpoint address="Rest"
              binding="customBinding"
              bindingConfiguration="rest-secure-nokeepalive"
              behaviorConfiguration="web"
              contract="SecureTransportDemo.Service.IGreetingService"
              name="rest-nokeepalive"/>
  </service>
</services>
<bindings>
  <customBinding>
    <binding name="soap-secure-nokeepalive">
      <textMessageEncoding />
      <httpsTransport allowCookies="false" 
                      keepAliveEnabled="false"/>
    </binding>
    <binding name="rest-secure-nokeepalive">
      <webMessageEncoding />
      <httpsTransport manualAddressing="true" 
                      allowCookies="false" 
                      keepAliveEnabled="false"/>
    </binding>
  </customBinding>
</bindings>
<behaviors>
  <endpointBehaviors>
    <behavior name="web">
      <webHttp automaticFormatSelectionEnabled="true"
               faultExceptionEnabled="true"
               helpEnabled="true"/>
    </behavior>
  </endpointBehaviors>
</behaviors>
