wcf - 基本 HTTP 绑定(bind)未正确配置

Question

我已经使用 wsHTTPBinding 配置了 WCF 服务，但即便如此我还是得到了错误

Contract requires Session, but Binding 'BasicHttpBinding' doesn't support it or isn't configured properly to support it.

这是服务契约(Contract)定义

<ServiceContract(SessionMode:=SessionMode.Required)>
Public Interface IPrivateService

这是服务实现定义

<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerSession)>
Public Class PrivateService
    Implements IPrivateService

这是配置设置

<services>
    <service behaviorConfiguration="behaviorAction" name="Viking.Service.PrivateService">
            <endpoint address="RequiredService" binding="wsHttpBinding" bindingConfiguration="bindingAction" contract="Viking.Service.IPrivateService">
              <identity>
                <dns value="localhost"/>
              </identity>
            </endpoint>
            <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
          </service>
</services>
<bindings>
          <wsHttpBinding>
            <binding name="bindingAction" transactionFlow="false" sendTimeout="00:30:00" receiveTimeout="00:30:00">
              <reliableSession enabled="true"/>
            </binding>
          </wsHttpBinding>
</bindings>

非常感谢有关此问题的任何建议。

如果您使用的是 wcf 4.0，请打开 web.config/app.config 并在 <system.serviceModel> 中添加以下标签标签。

  <protocolMapping>
  <add scheme="http" binding="wsHttpBinding"/>
</protocolMapping>
