WCF錯誤 - 連接被遠程主機關閉

Question

我有這個很奇怪的錯誤...

我正在開發一個WCF服務，我從其他人那裏接管了。有這樣定義的類稱爲用戶：

namespace WebApi.DataContracts 
{ 
    [DataContract] 
    public class User 
    { 
     [DataMember] 
     public int Id 
     { 
      get; 
      set; 
     } 
     [DataMember] 
     public string Username 
     { 
      set; 
      get; 
     } 
    ... 
     [DataMember] 
     public DateTime Birth 
     { 
      get; 
      set; 
     } 
     [DataMember] 
     public bool Newsletter 
     { 
      get; 
      set; 
     } 

等等

我做了一個API方法，返回此對象作爲數據

namespace WebApi 
{ 
    public class SoapApi : IApi 
    { 
     public DataContracts.User UserRegister() 
     { 
      DataContracts.User u = new DataContracts.User(); 
      return u; 
    } 
} 

當我嘗試從客戶端調用這個，我得到這個錯誤：

[SocketException (0x2746): An existing connection was forcibly closed by the remote host] 
    System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) +6132200 
    System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) +134 

[IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.] 
    System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) +300 
    System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) +26 
    System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead) +265 

[WebException: The underlying connection was closed: An unexpected error occurred on a receive.] 
    System.Net.HttpWebRequest.GetResponse() +6038435 
    ClassLib.HandlerFactory.AjaxProxy.ProcessRequest(HttpContext context) in ClassLib\HandlerFactory.cs:75 
    System.Web.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +100 
    System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +75 

在我看來，這個線

System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) +6132200 

表明，試圖發送可怕的大量字節 - 爲什麼是這樣？

更新：在我的客戶的web.config結合如下：

<bindings> 
    <basicHttpBinding> 
    <binding name="BasicHttpBinding_Api" closeTimeout="00:01:00" 
     openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 
     allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 
     maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" 
     messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 
     useDefaultWebProxy="true"> 
    <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> 
    <security mode="None"> 
     <transport clientCredentialType="None" proxyCredentialType="None" 
     realm="" /> 
     <message clientCredentialType="UserName" algorithmSuite="Default" /> 
    </security> 
    </binding> 
    <binding name="ApiBinding" closeTimeout="00:01:00" 
     openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" 
     allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" 
     maxBufferSize="2147483647" maxBufferPoolSize="2147483647" maxReceivedMessageSize="2147483647" 
     messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" 
     useDefaultWebProxy="true"> 
    <readerQuotas maxDepth="2147483647" maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxNameTableCharCount="2147483647" /> 
     <security mode="None"> 
     <transport clientCredentialType="None" proxyCredentialType="None" 
      realm="" /> 
     <message clientCredentialType="UserName" algorithmSuite="Default" /> 
     </security> 
    </binding> 
    </basicHttpBinding> 
</bindings> 

服務器的web.config綁定是：

<bindings> 
    <basicHttpBinding> 
    <binding name="ApiBinding" /> 
    </basicHttpBinding> 
    <webHttpBinding> 
    <binding name="ApiBinding" /> 
    </webHttpBinding> 
</bindings>

通過你的信息提供這似乎只是服務器端，這是不可能說出什麼問題。

所以：

• 更新與客戶端詳細

的信息現在，這個錯誤告訴我，有是有約束力的錯配或安全錯誤發生 - 雖然安全性設置爲無。因此，基於提供的信息，我的預感是客戶端和服務器之間的綁定不匹配，可能安全性是針對其他服務器的。
