WCF会话配置错误

我想在我的服务中启用（SessionMode=SessionMode.Required），因此启用后，使用WCF Client test测试该服务时，会出现以下错误：

无法处理该消息。这很可能是因为操作“”不正确，或者是因为消息包含无效或过期的安全上下文令牌，或者是因为绑定之间不匹配。如果服务因不活动而中止通道，则安全上下文令牌将无效。为了防止服务过早中止空闲会话，请增加服务端点的binding.HTTP GET Error上的接收超时

[ServiceBehaviorAttribute(InstanceContextMode = InstanceContextMode.PerCall)]
public class PublisherService : IPublisher
{
}

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

[ServiceBehaviorAttribute（InstanceContextMode=InstanceContextMode.PerCall）]
公共类PublisherService:IPPublisher
{
}
[ServiceContract（SessionMode=SessionMode.Required）]
公共接口IPPublisher
{
}

有谁能帮我解决这个问题。

拆下线路

从web.config文件。因为传输似乎需要HTTPS来加密凭据。

但我不需要加密凭据，只想运行服务。在web.config中添加此行
