Question

背景：我设置了一个具有两个意图的简单DialogFlow。设置为api v1并将webhook设置为故障服务器。我使用glitch.com托管了一些js来收集信息（用户要求）。

切换到api的v2可以解决此问题。我发现的所有示例都使用Firebase而不是您自己的服务器来托管Java脚本，这就是为什么我被卡住了，希望有人可以指出正确的方向，以便在v2中将数据发送到Google Assistant或从Google Assistant返回数据火力地堡。

请参见下面的代码

            // init project pkgs
            const express = require('express');
            const ApiAiAssistant = require('actions-on-google').ApiAiAssistant;
            const bodyParser = require('body-parser');
            const request = require('request');
            const app = express();
            const Map = require('es6-map');


            // Pretty JSON output for logs
            const prettyjson = require('prettyjson');
            const toSentence = require('underscore.string/toSentence');

            app.use(bodyParser.json({type: 'application/json'}));
            app.use(express.static('public'));

            // http://expressjs.com/en/starter/basic-routing.html
            app.get("/", function (request, response) {
              response.sendFile(__dirname + '/views/index.html');
            });

            // Handle webhook requests
            app.post('/', function(req, res, next) {
              // Log the request headers and body to help in debugging.
              // Check the webhook requests coming from Dialogflow by clicking the Logs button the sidebar.
              logObject('Request headers: ', req.headers);
              logObject('Request body: ', req.body);

              // Instantiate a new API.AI assistant object.
              const assistant = new ApiAiAssistant({request: req, response: res});

              // Declare our action parameters
              const PRICE_ACTION = 'price'; 

              // Create functions to handle price query
              function getPrice(assistant) {
                console.log('** Handling action: ' + PRICE_ACTION);
                let requestURL = 'https://blockchain.info/q/24hrprice';
                request(requestURL, function(error, response) {
                  if(error) {
                    console.log("got an error: " + error);
                    next(error);
                  } else {        
                    let price = response.body;

                    logObject('the current bitcoin price: ' , price);
                    // Respond to the user with the current temperature.
                    assistant.tell("The current bitcoin price is " + price);
                  }
                });
              }

              // Add handler functions to the action router.
              let actionRouter = new Map();
              actionRouter.set(PRICE_ACTION, getPrice);
              actionRouter.set(STATUS_ACTION, getStatus);

              // Route requests to the proper handler functions via the action router.
              assistant.handleRequest(actionRouter);
            });


            // Handle errors
            app.use(function (err, req, res, next) {
              console.error(err.stack);
              res.status(500).send('Oppss... could not check the bitcoin price');
            })

            // Pretty print objects for logging
            function logObject(message, object, options) {
              console.log(message);
              console.log(prettyjson.render(object, options));
            }

            // Listen for requests
            let server = app.listen(process.env.PORT, function () {
              console.log('--> Our Webhook is listening on ' + JSON.stringify(server.address()));
            });

您是否有任何特定原因要使用自己的服务器？

Firebase会自动处理请求，如果您打算公开发布“行动”，则Google的奖励计划应向您的帐户提供每月200美元的Cloud信用额度，以抵消个人应计费用。
