我正在为Alexa编写游戏，但需要用户输入。如果没有答案，则游戏应以用户分数的唯一消息结束。目前，我有Alexa提示用户这样。
this.emit(":ask", speech);
但是，如果用户选择不回答，则Alexa不会在没有任何消息的情况下结束。我检查了我是否可以在停止或取消处理程序中对此进行解释，但是该程序似乎并没有以这种方式退出。我如何不考虑输入并指定退出消息？这是我的完整代码供参考。

您应该在会话结束时查找sessiondeDrequest，因此您可以收听并相应地做出回应。应该请求。Type=='SessionEdedRequest'。就像LaunchRequest一样，它实际上并不是一个意图，我看到您已经在处理abinationRequest，因此应该很容易添加。
