从Firestore检索数据以在DialogFlow中显示
从Firestore检索数据以在DialogFlow中显示
提问于 2018-06-12 18:08:26
我正在尝试从firestore获取数据并将其显示在DialogFlow响应中。当我在DialogFlow中触发"buyerBusiness“intent时，函数web fulfillment成功，但检索到的数据没有显示为响应。当我安慰他们时，它会记录在日志中。下面是为此编写的处理程序函数。
function buyerBusiness(agent) {
console.log("buyer name is " + params.BuyerEntity);
var abc = new Set();
var results = [];
admin.firestore().collection('SuppBuyAssoc').where('Advertiser', '==', params.BuyerEntity).limit(5).get().then(snapshot => {
snapshot.forEach(doc => {
abc.add(doc.data().Agency);
});
var x = Array.from(abc);
var y;
for (var j = 0; j < x.length; j++) {
y = results.push(x[j]);
}
blueBird.all(results).then(function () {
console.log('results are: ' + results);
agent.add(results);
}).catch(eror => {
console.log("Errrrr");
console.log(eror);
})
console.log("results are:"+ results);
}).catch(reason => {
// res.send(reason)
console.log(reason);
})
// agent.add(`Testing this stuff`);
}以下是云函数的日志：

为了让Dialogflow fulfillment库跟踪您的异步请求，您需要返回从调用firestore获得的承诺。
尝试在admin.firestore().collection调用前添加return：
function buyerBusiness(agent) {
console.log("buyer name is " + params.BuyerEntity);
var abc = new Set();
var results = [];
return admin.firestore().collection(/* rest of code */页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
