Question

我正在使用Jovo Node.js框架为Amazon Alexa和Google Assistant平台编写语音优先应用程序。我向外部API发出了嵌套的http请求（第一个调用是获取所需的资源ID，作为第二个API调用的参数）。数据返回后，我想向应用程序的用户发送响应。但是，在测试过程中我什么也没收到。

我尝试从相同的.then（）内部发送响应，从API中获取数据并制定响应，还尝试了简单地在一个对象中返回该响应并链接另一个.then （）处理该诺言，然后尝试发送响应。这些选项都不起作用。

我在请求处理程序中将console.log记录为“ this”，然后在.then（）内部处理第一个API调用，然后在.then（）内部处理第二个API调用（以确保上下文相同））和相同的“ this”。

console.logging从API接收的数据也可以，所以我知道我正在从API得到响应。我只是在向用户发送回复时遇到麻烦。

下面是我的代码：

meetup.GetMeetupGroup(city).then((details) => {
    const id = details.next_event.id;
    console.log(id); // This works

    meetup.GetMeetupEvent(city, id).then((event) => {
        let response = {};
        response.speech = `<speak>The next learn to code meetup is ${event.name}.
                    It will be held on <say-as interpret-as="date">${event.local_date}</say-as>
                    at ${event.local_time} at ${event.venue.name}, which is located at
                    <say-as interpret-as="address">${event.venue.address_1}</say-as>. ${event.plain_text_description}. 
                    Would you like to <say-as interpret-as="characters">RSVP</say-as>?</speak>`;

        response.reprompt = `<speak>The next ${city} meetup will be on 
                    <say-as interpret-as="date">${event.local_date}</say-as>
                    at ${event.local_time} at ${event.venue.name},
                    <say-as interpret-as="address">${event.venue.address_1}</say-as>.
                    Do you want to go?</speak>`;
        console.log(response); // This works
        return response;

    }).then((res) => {
        console.log(res); // This works
        this.ask(res.speech, res.reprompt); // Here is where I'm attempting to send a response
    });
}).catch((error) => {
    console.log('Meetup API Error');
    console.log(error);
    this.tell('Sorry, your request could not be completed at this time.');
});

从这个承诺中得到回应的正确方法是什么？
