如何将Botframework网络聊天对话维持一个小时以上?

我浏览了有关botframework-webchat的文档，但找不到关于如何正确处理1个小时以上的对话的任何文档.如果网页在后台长时间闲置，则很可能发生这种情况.

I have looked through the documentation for botframework-webchat and have not been able to find any documentation on how conversations over 1 hour should be handled properly. This situation is most likely to occur if a web page is left idle in the background for an extended period of time.

只要网络聊天在网页上保持活动状态，便会保持直线连接.页面刷新后会发生此问题.

The directline connection is maintained as long as the webchat remains active on a web page. The problem occurs after a page refresh.

最初的短期解决方案是将相关对话信息存储在会话存储中，例如令牌.问题在于，会话的令牌每15分钟刷新一次.必须检索刷新的令牌，以便在刷新页面时保持对话.

The initial short term solution is to store the relevant conversation information in session storage, such as a token. The problem is that the token for the conversation is refreshed every 15 minutes. The refreshed token must be retrieved in order to maintain the conversation upon a page refresh.

我确信存在变通的解决办法，该事件可使用事件回调从Directline客户端对象中检索刷新的令牌.

I am sure a hacky work around exists for retrieving the refreshed token from the directline client object using an event callback.

理想情况下，我正在寻找一种干净的框架设计方法来处理这种情况.

尽管可行的解决方案总比没有解决方案好.

Though a working solution is better than no solution.
