这个错误与我在这里问的类似,但这次是 NodeJs 客户端。
我正在尝试查找到某个位置的路线。一旦在我的 webhook 上触发了意图,我就会使用 GoogleMapAPI 计算方向。但在它完成并发送响应之前,我在操作控制台上收到了错误消息。
我检查了总响应时间,它不到 2 秒,Google 的超时时间不到 5 秒。
我哪里错了???
将 express.js 与 Action-on-Google 节点客户端一起使用
'use strict';
const express = require('express');
const bodyParser = require('body-parser');
const intentHandler = require('./intent_handler')
const app = express();
app.use(bodyParser.json());
const ApiAiAssistant = require('actions-on-google').ApiAiAssistant;
// Create functions to handle requests here
....
....
const DIRECTION_INTENT = 'action_direction';
function MyAssistant(req, res) {
const assistant = new ApiAiAssistant({request: req, response: res});
assistant.handleRequest(responseHandler(assistant));
}
function responseHandler (assistant) {
// intent contains the name of the intent you defined in the Actions area of API.AI
let intent = assistant.getIntent();
switch (intent) {
case WELCOME_INTENT:
...
break;
case WELCOME_FALLBACK_PERMISSION_INTENT:
...
break;
case DIRECTION_INTENT:
console.log(">>>>>>>DIRECTION_INTENT<<<<<<<");
intentHandler.directionIntent(assistant);
break;
}
}
app.post('/', function (req, res) {
MyAssistant(req, res);
});
app.listen(8080, function () {
console.log('app listening on port 8080!')
});
处理程序代码
'use strict';
const speech = require("./speech_template");
const direction = require("./directionModule");
const intent_handler = {
'welcomeIntent': function (assistant) {
.....
},
'welcomeFallbackPermissionIntent': function (assistant) {
.....
},
'directionIntent':function (assistant) {
console.log('direction intent');
direction.getDirectionWithSavedAddress(function (response) {
assistant.ask(response);
});
}
};
module.exports = intent_handler;
方向提取 --- 错误在完成之前出现在操作控制台上
'use strict';
const striptags = require('striptags');
const speech = require("./speech_template");
let googleMapsClient = require('@google/maps').createClient({
key: global.GOOGLE_DIRECTION_KEY
});
const directionModule = {
'getDirectionWithSavedAddress': function (eventCallback) {
let myAdd = <From Saved Data>;
if (myAdd === undefined) {
console.log("error......");
}
let destination = <From Saved Data>;
this.getDirectionWithAddress(myAdd, destination, function (dir) {
....
if(SUCCESS){
eventCallback(`<speak> ${steps} </speak>`);
}else{
eventCallback(`<speak> ${speech.ERROR_DIRECTIONS} </speak>`);
}
});
},
'getDirectionWithAddress': function (add1, add2, eventCallback) {
let dir = {};
googleMapsClient.directions({
origin: add1,
destination: add2,
mode: "driving",
departure_time: "now"
}, function (err, response) {
if (!err) {
console.log(response.json.routes[0]);
....
....
....
} else {
console.log(`Error --> ${err.toString()}`);
....
}
eventCallback(dir);
});
}
};
module.exports = directionModule;
更新 我正在通过 WebStorm 在本地运行代码,并使用 ngrok 通过端口转发公开 webhook。

这看起来像在我的回调完成之前,我的 webhook 正在向 Google Actions 发送空响应。
为什么会发生这种情况以及如何解决????
