它是一个故事模式技巧，从麻线上讲故事[不读它 （（（（Alexa希望在8秒内得到后端处理的响应，因此在接收和发送消息后，我们将在7秒左右留下。记住在设计技能时保持响应时间短而快。如果你的技能变为流行的，您可能需要考虑如何从非常大的数据库表访问数据，在调用外部服务，缓存数据和许多其他事情时应对超时.Lambda本身的架构可以很好地扩展。向下滚动并在基本设置中增加超时至7秒。
需要为Lambda提供可能被调用的所有代码和库。我们上传了一个zip文件，其中包含我们技能使用的node_modules（alexa-sdk和xml2js）。如果你想创建一个非常简单的Alexa技能，你可以使用蓝图和alexa-skill-kit-sdk-factskill。这将创建一个带有alexa-sdk预加载的Lambda函数。如果你创建自己的zip文件包，那么要小心拉链的根目录而不是自定义文件夹。）））））
