Question

我正在尝试在wsHttpBinding端点公开WCF服务，它给出了以下错误消息：

合同需要Session，但是Binding 'BasicHttpBinding'不支持它或未正确配置支持它。

这是界面：

[ServiceContract(Namespace="http://server.com/orderservices/",SessionMode=SessionMode.Required)]
public interface IOrderService
{
    [OperationContract(IsInitiating=true,IsTerminating=false)]
    string GetOrderNumber();

    [OperationContract(IsInitiating = false, IsTerminating = true)]
    void CreateOrder(string orderXML);
}

这是我的web.config文件（该服务托管在IIS 7中）：

<system.serviceModel>
   <bindings>
      <wsHttpBinding>
         <binding name="longTimeoutBinding" 
             receiveTimeout="00:10:00" sendTimeout="00:10:00">
         </binding>
      </wsHttpBinding>
   </bindings>
   <services>
      <service name="eMidWare.OrderService">
         <host>
            <baseAddresses>
                <add baseAddress = "http://localhost/" />
            </baseAddresses>
         </host>
         <!-- Service Endpoints -->
         <endpoint 
            address="" 
            binding="wsHttpBinding" bindingConfiguration="longTimeoutBinding"
            contract="eMidWare.IPricingDataService">
         </endpoint>
         <endpoint 
             address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
   </services>
   <behaviors>
      <serviceBehaviors>
         <behavior>
            <serviceDebug includeExceptionDetailInFaults="True" />
         </behavior>
      </serviceBehaviors>
   </behaviors>
</system.serviceModel>

Answer 1

嗯......检查你的服务合同 - 这是一个IOrderService

[ServiceContract(Namespace="http://server.com/orderservices/",SessionMode=SessionMode.Required)]
public interface IOrderService
{
}

但在您的配置中，您正在为eMidWare.IPricingDataService

设置端点

<endpoint 
    address="" 
    binding="wsHttpBinding" bindingConfiguration="longTimeoutBinding"
    contract="eMidWare.IPricingDataService">

因此，我相信，.NET / WCF 4将启动默认端点，默认情况下为basicHttpBinding方案的http:// ....

如果您已经发布了服务界面，我可以肯定地说，但我相信您的服务界面上有类似的内容：

 [ServiceContract(SessionMode = SessionMode.Required)]

这需要会话，而BasicHttpBinding不支持会话。如果需要进行会话，则需要使用wsHttpBinding。

获取与basicHttpBinding相关的错误消息，即使我正在使用wsHttpBinding
