DialogFlow应用程序不会在Heroku中部署 [英] DialogFlow app does not get deployed in Heroku
本文介绍了DialogFlow应用程序不会在Heroku中部署的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我没有使用对话框流程的经验，因此我试图按照这篇youtube教程
来制作一个机器人。现在，当我在 DialogFlow控制台上测试它时，该机器人运行良好，但它不会部署在Heroku上。每当我尝试打开应用程序应该部署到的位置时，我都会继续获取内部服务器错误（曾用于 {speech：，displayText：，source：webhook } 在我应用此之前）。它表示无法加载资源：服务器在控制台中响应状态为500（内部服务器错误）。
我尝试了文档，但我使用了Heroku而不是谷歌平台，我不知道我是否正确做事。
这是我从最新版本获得的当前版本日志：
-----> Node.js应用检测到

NPM_CONFIG_LOGLEVEL =错误
NPM_CONFIG_PRODUCTION = true

另外，我试过在localhost上部署应用程序，并且一直收到这个错误信息：

解决方案
问题在于 https://dialogflow.com/docs/getting-started/basic-fulfillment-conversation 假设您使用的是G oogle的云端功能（GCF）。 GCF使得部署node.js功能变得非常简单，无需将这些功能附加到HTTP端点所需的一些样板代码。
然而，Heroku需要明确设置这些端点。 GCF希望Heroku支持的 const express = require（'express'）
const PORT = process.env.PORT || 5000
express（）
.use（express.static（path.join（__ dirname，'public'）））
.get（'/'，（req，res ）=> exports.makeSandwich（req，res））
.listen（PORT，（）=> console.log（`Listening on $ {PORT}`））;
您还需要调整package.json以确保它包含 express 包。
I have no experience whatsoever with using dialog flow so I'm trying to follow this youtube tutorial
to make a bot. Now, the bot works well when I tested it on the DialogFlow console, but it doesn't get deployed on Heroku. Whenever I try to open the url where the app's supposed to be deployed in, I keep on getting "Internal server error" (this used to be {"speech":"","displayText":"","source":"webhook"} before I applied this). It says "Failed to load resource: the server responded with a status of 500 (Internal Server Error)" in the console.
I tried following the docs here but I used Heroku instead of Google Platform and I'm not sure if I'm doing things right.
This is the current build log I got from the latest build:

Please help me fix this error. I've posted the code here.
additionally, i've tried deploying the app on localhost and i keep getting this error:

解决方案
The problem is that the directions at https://dialogflow.com/docs/getting-started/basic-fulfillment-conversation assume you're using Google's Cloud Functions (GCF). GCF makes it simple to deploy node.js functions without some boilerplate code required to attach those functions to an HTTP endpoint.
Heroku, however, needs to have those endpoints explicitly setup. GCF expects an express-like environment, which is one that Heroku also supports. Based on the barebones Heroku example at https://github.com/heroku/node-js-getting-started/blob/master/index.js, you might need to add lines such as this (which I haven't tested) to invoke your makeSandwich function:
const express = require('express')
const PORT = process.env.PORT || 5000
express()
.use(express.static(path.join(__dirname, 'public')))
.get('/', (req, res) => exports.makeSandwich( req, res ))
.listen(PORT, () => console.log(`Listening on ${ PORT }`));
You'll also need to adjust your package.json to make sure it includes the express package.
这篇关于DialogFlow应用程序不会在Heroku中部署的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
