google-cloud-functions - 错误:WebhookClient.handleRequest 处没有请求意图的处理程序
问题描述
调用云函数的默认意图会出错
Error: No handler for requested intent
at WebhookClient.handleRequest (/user_code/node_modules/dialogflow-fulfillment/src/dialogflow-fulfillment.js:287:29)
at exports.dialogflowFirebaseFulfillment.functions.https.onRequest (/user_code/index.js:73:11)

正如我在诊断信息日志中的 webresponse 所示。
{
"responseId": "86043a10-8bc2-4ee7-8e8b-1e997289ad7c",
"queryResult": {
"queryText": "hi",
"action": "input.welcome",
"parameters": {},
"allRequiredParamsPresent": true,
"fulfillmentText": "Hi. Am Uma. Kindly let me know your experience facing an issue.",
"fulfillmentMessages": [
{
"text": {
"text": [
"Hi. Am Uma and welcome to support. Kindly let me know your experience facing an issue."
]
}
}
],
"outputContexts": [
{

"lifespanCount": 2
}
],
"intent": {
"name": "projects/handymanticketagent/agent/intents/c58f706f-6cb6-499d-9ce2-459e8054ddc1",
"displayName": "Default Welcome Intent"
},
"intentDetectionConfidence": 1,
"diagnosticInfo": {

},
"languageCode": "en"
},
"webhookStatus": {
"code": 4,
"message": "Webhook call failed. Error: Request timeout."
}
}
根据此处的堆栈溢出答案,添加了一个映射到函数的意图,但仍然出现错误并且可以进一步发展。云功能控制台在哪里以及如何说我的请求缺少处理程序?
更新:正如@prisoner 所说,包括我的云功能代码。
'use strict';
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const { WebhookClient } = require('dialogflow-fulfillment');
process.env.DEBUG = 'dialogflow:*'; // enables lib debugging statements
admin.initializeApp(functions.config().firebase);
const db = admin.firestore();
exports.dialogflowFirebaseFulfillment = functions.https.onRequest((request, response) => {
console.log(request.body.queryResult.fulfillmentText);
console.log(request);
console.log(response);
const agent = new WebhookClient({ request, response });
console.log(agent);
function writeToDb(agent) {
// Get parameter from Dialogflow with the string to add to the database
const databaseEntry = agent.parameters.databaseEntry;
console.log(databaseEntry);
// Get the database collection 'dialogflow' and document 'agent' and store
// the document {entry: "<value of database entry>"} in the 'agent' document
const dialogflowAgentRef = db.collection('dialogflow').doc('agent');
console.log(dialogflowAgentRef);
return db.runTransaction(t => {
t.set(dialogflowAgentRef, { entry: databaseEntry });
console.log(Promise.resolve('Write complete'));
return Promise.resolve('Write complete');
}).then(doc => {
agent.add('Wrote "${databaseEntry}" to the Firestore database.');
return null;
}).catch(err => {
if (err) {
console.log(err.stack);
}
console.log('Error writing to Firestore: ${err}');
agent.add('Failed to write "${databaseEntry}" to the Firestore database.');
});
}
function readFromDb(agent) {
console.log(agent);
// Get the database collection 'dialogflow' and document 'agent'
const dialogflowAgentDoc = db.collection('dialogflow').doc('agent');
console.log(dialogflowAgentDoc);
// Get the value of 'entry' in the document and send it to the user
return dialogflowAgentDoc.get()
.then(doc => {
if (!doc.exists) {
agent.add('No data found in the database!');
} else {
agent.add(doc.data().entry);
}
return Promise.resolve('Read complete');
}).catch(() => {
agent.add('Error reading entry from the Firestore database.');
agent.add('Please add a entry to the database first by saying, "Write <your phrase> to the database"');
});
}
function defaultwelcomeintent_function(agent) {
console.log(agent);
}
// Map from Dialogflow intent names to functions to be run when the intent is matched
let intentMap = new Map();
intentMap.set('defaultwelcomeintent-followup', defaultwelcomeintent_function);
intentMap.set('ReadFromFirestore', readFromDb);
intentMap.set('WriteToFirestore', writeToDb);
console.log(intentMap);
agent.handleRequest(intentMap);
});
解决方案
诊断信息表明该履行的意图的显示名称是“默认欢迎意图”:
"intent": {
"name": "projects/handymanticketagent/agent/intents/c58f706f-6cb6-499d-9ce2-459e8054ddc1",
"displayName": "Default Welcome Intent"
},
所以你需要像这样为它创建一个映射:
intentMap.set('Default Welcome Intent', defaultwelcomeintent_function);
defaultwelcomeintent_function
您在云函数中定义的处理程序在哪里。
