没有任何问题，如果你还有疑问，需要远程协助，请购买企业版
通过查看其他issues我知道用RpcContext.GetContext().GetAttachment("payload")来获取payload
看到作者在网关ServicesController中用RpcContext.GetContext().SetAttachment("payload", payload);来传递payload
我调试了作者的Surging.Services.Client，当中也有RpcContext.GetContext().SetAttachment("xid",124);这样在接口中中可以接收到xid
但是我通过网关访问接口，接口中RpcContext.GetContext().GetAttachment("payload")一直是空的，调试中，网关的payload是有值的，在接口里面获取却是null
请问是我使用的问题么，是否需要在接口上配置什么？
目前一直通过继承RequestData来获取payload
