这是我的 server.ts 文件：

import express, { Request, Response } from 'express';
import path from 'path';
import mustache from 'mustache-express';
import dotenv from 'dotenv';
import mainRoutes from './routes/index';

dotenv.config();

const server = express();
server.set('view engine', 'mustache');
server.set('views', path.join(__dirname, 'views'));
server.engine('mustache', mustache());

server.use(express.static(path.join(__dirname, '../public')));
server.use(express.urlencoded({extended: true}));
server.use(mainRoutes);
server.use((req: Request, res: Response)=>{
    res.status(404).render('pages/404')
});
server.listen(process.env.PORT);

我的路线：

import { Router } from "express";
import * as HomeController from '../controllers/homeController'
import * as UserController from '../controllers/userController'
import * as SearchController from '../controllers/searchController'

const router = Router()
router.get('/', HomeController.home)
router.get('/cadastro', HomeController.register)
router.get('/usuarios', UserController.users)
router.post('/novousuario', UserController.newUser)
router.get('/usuario/:id/editar', UserController.editUser)
router.get('/usuario/:id/excluir', UserController.deleteUser)
router.post('/novousuarioeditado/:id', UserController.newEditUser)
router.get('/search', SearchController.search)

export default router

浏览器显示错误503，路由似乎有问题，在CRUD应用中注册时，它应该请求POST路由并立即将其重定向给用户，但它只是给出了一个错误在应用程序中

记住一切都在本地运行，没有明显的错误

  • 欢迎来到 Stack Overflow。 Please don't post screenshots of text。它们无法被屏幕阅读器等自适应技术的用户搜索或复制，甚至无法使用。相反，将代码作为文本直接粘贴到您的问题中。如果选择它并单击{} 按钮或 Ctrl+K 代码块将缩进四个空格，这将导致其呈现为代码。
  • 您在上面共享的代码均不相关。这是数据库连接错误；您的数据库不会在 Heroku 的本地主机上。你在哪里配置？你用的是 Knex 还是什么的？
  • 我真的看到问题是这样的，我要配置我的环境变量，代码中使用的.env，并且我已经在本地创建了数据库，意图是如何上传它到heroku？

标签： node.js typescript express heroku econnrefused


【解决方案1】：

端口 5432 提示您的程序正在尝试连接到本地主机上的 postgreSQL。这可能是它在您自己的机器上开发时的工作方式。

但是，在 Heroku 上，您的 postgreSQL 服务器与您的 web dyno 不在同一台机器上，因此无法连接到 localhost:5432。 econnrefused 错误来自操作系统，它表示您尝试连接的端口上没有任何运行。

Heroku，当您 provision a postgreSQL database instance 时，会为您提供一个名为 DATABASE_URL 的环境变量，该变量可用于您的应用程序。您应该使用它来连接到您的数据库。

【讨论】：

  • 我得到了这个 DATABASE_URL，我在云中使用了这个数据库中的信息，我连接到 dbeaver 客户端，建立连接，创建表和列，当进入应用程序时，当他需要时访问创建用户的路线，他给出了一个错误，我知道还没有完全连接，记住我的应用程序是一个 CRUD，用 nodejs(express)，打字稿，我用 sequelize，我用 dotenv，来创建环境变量，在heroku里面我也创建了这些变量，把云银行提供给我的信息放上去，会缺少什么？
