我正在为Alexa编写游戏，但用户输入是必需的。如果没有答案，则游戏应该以用户得分的唯一消息结束。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不会收到任何消息。我检查了我是否可以在Stop或Cancel处理程序中解释这个问题，但程序似乎没有退出。如何解释无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SessionEndedRequest，以便您可以监听并相应地做出响应。它应该是request.type =='SessionEndedRequest'。就像LaunchRequest一样，它实际上并不是一个意图，我看到你已经在处理LaunchRequest，所以应该很容易添加。
