Вот мой код. Как настроить его так, чтобы он возвращал ответ для интеграции с Google Assistant? Я хотел бы использовать этот код в встроенном редакторе кода Dialogflow или развернуть его для функций firebase.
process.env.DEBUG = 'dialogflow:debug'; // enables lib debugging statements
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
const agent = new WebhookClient({ request, response });
console.log('Dialogflow Request headers: ' + JSON.stringify(request.headers));
console.log('Dialogflow Request body: ' + JSON.stringify(request.body));
function getProjects(agent){
const api = 'https://playhacker.com/wp-json/wp/v2';
const tag = agent.parameters.tag;
//let url = `${api}/posts?tags=${tag}&_embed`;
let getPosts = (tag, callback) => {
let url = `${api}/posts?tags=${tag}&_embed`;
request({url}, (err, res, body) => {
if (err) {
callback('Sorry, there was an error getting posts from our blog', err);
return;
} else {
let posts = JSON.parse(body);
if (posts.length === 0) {
callback(`It does not seem like there is any content available on this topic`);
return;
} else {
let formattedPosts = posts.map((post) => {
return {
"payload": {
"google": {
"expectUserResponse": true,
"richResponse": {
"items": [
{
"simpleResponse": {
"textToSpeech": "Here is a project we found for you"
}
},
{
"basicCard": {
"title": post.title.rendered,
"subtitle": "Project",
"formattedText": post.excerpt.rendered.replace(/<(?:.|\\n)*?>/gm, '').replace(/&[^\\s]*/, ''),
"image": {
"url": post._embedded['wp:featuredmedia'][0].media_details.sizes.listing.source_url,
"accessibilityText": "featured image"
},
"buttons": [
{
"title": "Read more",
"openUrlAction": {
"url": post.link
}
}
],
"imageDisplayOptions": "CROPPED"
}
}
]
}
}
}
};
});
formattedPosts.unshift({
type: 0,
platform: 'google',
speech: 'Sure, here are some helpful projects'
});
callback(undefined, formattedPosts);
return;
}
}
});
};
}
let intentMap = new Map();
intentMap.set('getProjects',getProjects);
agent.handleRequest(intentMap);
});
Когда я запускаю его в встроенном редакторе Dialogflow, я получаю эту ошибку:
