每当我尝试将ActivateSessionRequest发送到opcua服务器时，都会引发错误，指出“ BadSessionNotActivated ”。下面是ActivateSessionRequest的消息格式：
var ActivateSessionRequest v_activateSessionReq := {
requestHeader := session_reqHeader,

Client-Server Communication 如图所示，ActivateSessionRequest通过将SessionId和AuthenticationToken发送到服务器而成功完成。 ActivateSessionRequest的头包含AuthenticationToken。但是，如何向服务器提供SessionId？是因为我没有在ActivateSessionRequest中提供SessionId导致服务器抛出错误还是由于其他错误？有人可以指导我吗？
任何反馈都非常感谢。预先谢谢你
