1. gmail

此示例演示了如何使用“If This Then That”（http://ifttt.com）使Cozmo在Gmail帐户收到电子邮件时作出回应。以下说明将引导您在IFTTT网站上设置小程序。当调用applet触发器（发送在此示例中启动的Web服务器收到的Web请求）时，Cozmo将播放动画，说出电子邮件发件人的姓名并在他的脸上显示邮箱图像。

此IFTTT示例使用Flask Web框架并且是同步的，与其他异步的IFTTT示例不同并使用aiohttp。在此示例中，IFTTT Web请求由函数receive_ifttt_web_request接收。进入该方法的每个Web请求都会添加到Queue ifttt_queue，并且HTTP状态代码200或503会立即返回到IFTTT。该队列由worker函数检查，该函数在后台线程上运行（由run函数启动）。当worker函数在队列中找到新请求时，请求将从队列中删除并在方法then_that_action中处理。

与ifttt_sports.py示例一样，此示例演示了如何使用“If This Then That”（http://ifttt.com）使Cozmo在您指定的团队有游戏内或最终得分更新时做出响应。以下说明将引导您完成设置
在IFTTT网站上发布一个applet。当调用applet触发器（发送在此示例中启动的烧瓶服务器接收的Web请求）时，Cozmo将播放动画，在他的脸上显示图像，并说出游戏内更新。

        as the endpoint. For instance, if your public url is http://my.url.com,
        then in the IFTTT web request URL field put the following:
        http://my.url.com/iftttSports. Then, this endpoint will be called when
