wcf - 合约需要 Session，但 Binding ‘WSHttpBinding’ 不支持它或未正确配置以支持它

Question

我已指定需要 session 的服务契约(Contract)。

[ServiceContract(SessionMode = SessionMode.Required)] 
public interface ITicketSales
{
}

服务装饰成这样:

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Single)]
public class TicketSalesService : ITicketSales
{
}

这是我的 App.config 文件:

<system.serviceModel>    
<services>     
  <service name="InternetRailwayTicketSales.TicketSalesImplementations.TicketSalesService" behaviorConfiguration="defaultBehavior">

    <host>
      <baseAddresses>
        <add baseAddress = "https://localhost/TicketSales/"></add>
      </baseAddresses>
    </host>

    <endpoint address="MainService" binding="wsHttpBinding" bindingConfiguration="wsSecureConfiguration"
      contract="InternetRailwayTicketSales.TicketSalesInterface.ITicketSales" />
    <endpoint address="mex" binding="mexHttpsBinding"
      contract="IMetadataExchange"/>
  </service>
</services>

<bindings>
  <wsHttpBinding>
    <binding name="wsSecureConfiguration">
      <security mode="Transport">
        <transport clientCredentialType="None"></transport>
      </security>
    </binding>
  </wsHttpBinding>
</bindings>

<behaviors>
  <serviceBehaviors>
    <behavior name="defaultBehavior">
      <serviceThrottling maxConcurrentInstances="5000" maxConcurrentSessions="5000"/>
      <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="True" />
    </behavior>
  </serviceBehaviors>
</behaviors>

当我按 F5 时，我收到错误消息“契约(Contract)需要 session ，但绑定(bind)‘WSHttpBinding’不支持它或未正确配置以支持它。”

我真的需要支持 SSL 并需要 session 的 channel 。

您可以通过启用消息安全来支持 session :

<binding name="wsHttpSecureSession">
<security>
<message establishSecurityContext="true"/>
</security>
</binding>

如果您需要传输安全，您可能需要指定客户端凭证类型
