我正在制作一个可以根据位置搜索餐厅的机器人。谁能帮我为什么这不出现在FB Messenger中？
restaurants(result.getMemory('location').raw)
.then(res=>{
message.addReply(res);
message.reply();
});
}
对餐厅函数的调用返回了YELP API调用（一组餐厅）的结果，但是当我将其添加为对消息的答复时，FB Messenger中没有任何反应。
这是message.js的完整代码：
const recastai = require('recastai');
const restaurants = require('./restaurants');
// This function is the core of the bot behaviour
const replyMessage = (message) => {
// Instantiate Recast.AI SDK, just for request service
const request = new recastai.request(process.env.REQUEST_TOKEN,
process.env.LANGUAGE);
// Get text from message received
const text = message.content;
console.log('I receive: ', text);
// Get senderId to catch unique conversation_token
const senderId = message.senderId;
// Call Recast.AI SDK, through /converse route
request.converseText(text, { conversationToken: senderId })
.then(result => {
//Recast takes text analyses that, returns a result object, generates replies adds messages to reply stack and then sends the replies
//Call Yelp API with when the intent is Location. When Yelp returns result we add it to the result.replies array.
//Then we add everything in result.replies to the messaging queue that sends the responses to FB
if (result.action) {
console.log('The conversation action is: ', result.action.slug);
}
// If there is not any message return by Recast.AI for this current conversation
if (!result.replies.length) {
message.addReply({ type: 'text', content: 'I don\'t have the reply to this yet :)' });
} else {
// Add each reply received from API to replies stack
result.replies.forEach(replyContent => message.addReply({ type: 'text', content: replyContent }));
}
// Send all replies
message.reply()
//send initial reply generated by Recast first
.then(() => {
//call restaurant function that returns a list of results from API
//if the action is location and done
if(result.action && result.action.slug === 'location' && result.action.done){
restaurants(result.getMemory('location').raw)
.then(res=>{
console.log(res);
message.addReply(res);
message.reply();
});
}
})
.catch(err => {
console.error('Error while sending message to channel', err);
});
})
.catch(err => {
console.error('Error while sending message to Recast.AI', err);
});
};
module.exports = replyMessage;
这是我的restaurant.js代码，该代码已导入到机器人行为的message.js文件中：
const rp = require('request-promise');
// Load configuration
require('./config');
const restaurants = (location) => {
return Promise.all([
yelpCall(location)
]).then(result => {
//result contains the return value from Yelp call
return result;
});
};
const yelpCall = (location) => {
const auth = {
method: 'POST',
url: 'https://api.yelp.com/oauth2/token?grant_type=client_credentials&client_id='+ process.env.YELP_APP_ID +'&client_secret='+process.env.APP_SECRET
};
return rp(auth)
.then(result => {
const tokens = JSON.parse(result);
return tokens;
})
.then(result=>{
const options = {
url: 'https://api.yelp.com/v3/businesses/search?location=' + location + "&term=thai",
headers: {Authorization: "Bearer " + result.access_token}
};
return rp(options).then(findings =>{
return findings;
});
});
};
module.exports = restaurants;
最佳答案
一些想法：
然后可以使用message.reply，因此可以在两个地方使用return message.reply()。
然后可以使用request.converseText()，因此return request.converseText(...)。
然后可以使用restaurants，因此return restaurants(...)。
在message.js中，在两个地方将message.addReply()传递为{type:..., content:...}形式的对象，但最终只是res。那是对的吗？
在restaurants.js中，似乎不需要Promise.all()。它将导致其结果包装在数组中。 module.exports = location => yelpCall(location);似乎更合适。
