Question

我有一个wcf服务，这是我的服务配置：

<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
<diagnostics>
  <messageLogging logEntireMessage="true" logMalformedMessages="true" logMessagesAtServiceLevel="true" logMessagesAtTransportLevel="true" />
</diagnostics>
<services>
  <service name="CDU.Services.cdu" behaviorConfiguration="ICDUService">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_CDU" contract="CDU.Services.Icdu" name="BasicHttpBinding_CDU">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost/CDU.Services/cdu.svc" />
      </baseAddresses>
    </host>
  </service>
</services>
<behaviors>
  <serviceBehaviors>
    <behavior name="ICDUService">
      <serviceMetadata httpGetEnabled="true" />
      <dataContractSerializer maxItemsInObjectGraph="2147483646" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding_CDU" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" 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>

当交换的数据是字符串时，我的服务与wcf测试客户端相处得很好。此搜索我想要检索一个对象，我得到了这个错误：图像2

   An error occurred while receiving the HTTP response to http://localhost/CDU.Services/cdu.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.

我在数据合同中添加了用户类型，但这并没有解决它：

    [DataContract]
public class CompositeType
{
    private bool boolValue = true;
    private string stringValue = "Hello ";
    private User userValue = new User();

    /// <summary>
    /// Gets or sets a value indicating whether [bool value].
    /// </summary>
    /// <value>
    ///   <c>true</c> if [bool value]; otherwise, <c>false</c>.
    /// </value>
    [DataMember]
    public bool BoolValue
    {
        get { return boolValue; }
        set { boolValue = value; }
    }

    /// <summary>
    /// Gets or sets the string value.
    /// </summary>
    /// <value>
    /// The string value.
    /// </value>
    [DataMember]
    public string StringValue
    {
        get { return stringValue; }
        set { stringValue = value; }
    }

    [DataMember]
    public User UserValue
    {
        get { return userValue; }
        set { userValue = value; }
    }
}

任何想法好吗？
