接收HTTP响应错误时发生错误

我在使用WCF客户端进行测试时遇到了我的wcf服务问题。当我调试时，我发现数据从函数中返回，但在响应期间出错。有人能帮我弄清楚我错过了什么吗？接收HTTP响应错误时发生错误

这是我的服务配置文件：

public List<PO> GetAllPOs() 
{ 
    var data = new List<PO>(); 
    try 
    { 
     var manager = new EntityReaderManager<PO>(ConfigurationManager.AppSettings("FilemakerDB"]); 
     data = manager.GetEntityList(); 
    } 
    catch (Exception ex) 
    { 
     ILogger logger = new Logger(typeof(FilemakerDataService)); 
     logger.Error(ex.Message); 

    } 

    return data; 
}

下面是配置文件：

<system.serviceModel>  
    <diagnostics> 
     <messageLogging logEntireMessage="true" logKnownPii="true" logMalformedMessages="true" 
     logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" 
     maxSizeOfMessageToLog="2147483647" /> 
     <endToEndTracing propagateActivity="true" activityTracing="false" 
     messageFlowTracing="true" /> 
    </diagnostics>

    <wsHttpBinding>

     openTimeout="10:10:00" receiveTimeout="10:10:00" sendTimeout="10:10:00" 
     maxBufferPoolSize="655360" maxReceivedMessageSize="655360"> 

     <security mode="None" />

      name="Custom.WSHTTPBinding.Configuration" contract="AerWorldwide.Service.Web.FilemakerData.IFilemakerDataService"> 
      <identity> 
      <dns value="localhost" /> 
      </identity> 
     </endpoint>

     <serviceDebug includeExceptionDetailInFaults="true" /> 
     </behavior> 
    </serviceBehaviors> 
    </behaviors>  
</system.serviceModel>

错误：

你得到的错误是什么？ – fenix2222

无法从传输连接读取数据：现有连接被远程主机强制关闭。 at System.Net.Sockets.NetworkStream.Read（Byte [] buffer，Int32 offset，Int32 size） at System.Net.PooledStream.Read（Byte [] buffer，Int32 offset，Int32 size） at System.Net。 Connection.SyncRead（HttpWebRequest请求，布尔userRetrievedStream，布尔probeRead）内部例外：现有连接被远程主机强制关闭在System.Net.Sockets.Socket.Receive（Byte []缓冲区，Int32偏移量，Int32大小，SocketFlags socketFlags） –

我还发现端点有一个名称值，我把它拿出来。尽管 –

首先启用您的服务Tracing和看看有什么异常的原因。

此外，您可能会考虑在您的服务器和客户端上增加ReaderQuotas，以便通过大容量数据时不会出现任何问题。如下图所示样品：

<wsHttpBinding> 
     <binding name="Custom.WSHTTPBinding.Configuration" closeTimeout="10:10:00" 
     openTimeout="10:10:00" receiveTimeout="10:10:00" sendTimeout="10:10:00" 
     maxBufferPoolSize="655360" maxReceivedMessageSize="655360"> 
     <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" 
       maxArrayLength="2147483647" maxBytesPerRead="2147483647" 
       maxNameTableCharCount="2147483647" /> 
     <security mode="None" /> 
     </binding> 
    </wsHttpBinding>

此外，我在你的代码要传递直接的实体框架获取的对象看。有些情况下，实体框架对象不会被反序列化，并可能导致异常。创建一个简单的POCO，然后填充提取的数据并返回POCO。
