我有一个如图所示的Firebase Firestore
zaaidata字段是一个对象。我想在通过webhook发送到Dialogflow中我的聊天机器人的响应中使用tot和van的值。
我设法查询了文档,但无法检索特定值。我已经试过了:
doc.data [“ zaaidata”] [“ van”]
doc.data(“ zaaidata”)(“ van”)
doc.data.get(“ zaaidata”)[“ van”]
这是我的index.js
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
var db = admin.firestore();
exports.webhook = functions.https.onRequest((req, res) => {
let parameters = req.body.result.parameters;
var groentenRef = db.collection('groenten').doc(parameters.groente);
var query = groentenRef.get()
.then(doc => {
if (!doc.exists) {
response = "No such document!";
} else {
response = "Je kan zaaien tussen " + doc.data["zaaidata"]["van"] + " en " + doc.data["zaaidata"]["tot"];
}
res.setHeader('Content-Type', 'application/json');
res.send(JSON.stringify({ "speech": response, "displayText": response}));
})
.catch(err => {
console.log('Error getting documents', err);
});
});
有人可以帮我吗?谢谢!
最佳答案
你尝试过这个吗
response = "Je kan zaaien tussen " + doc.data().zaaidata.van + " en " + doc.data().zaaidata.tot;
