运行 heroku --tail logs 时，我收到以下错误响应：

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

通过浏览器查看它显示错误 503，路由似乎有问题，在 CRUD 应用程序中注册时，它应该请求 POST 路由并立即将其重定向给用户，但它只是在应用程序中给出错误

记住一切都在本地工作，没有明显的错误

端口 5432 提示您的程序正在尝试连接到本地主机上的 postgreSQL。这可能就是它在您自己的机器上进行开发的方式。

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，当您配置 postgreSQL 数据库实例时，会为您提供一个名为的环境变量，该变量DATABASE_URL可用于您的应用程序。您应该使用它来连接到您的数据库。
