node.js - 无法设置简单的 Node.js 服务器

问题描述

我对 Node.js 和整个后端非常陌生。我正在尝试设置简单的 node.js 服务器来创建授权（管理员，用户）我猜没什么特别的。当我尝试使用 localhost:5000 在浏览器中输入我的服务器时，我收到此错误。

localhost/:1 GET http://localhost:5000/ 404 (Not Found)

使用 http://localhost:5000/auth/login 或任何其他路由时也是如此。奇怪的是，与此同时，我总是server started on port 5000在 VSC 终端中收到消息。

还有几次我设法 REG 在 VSC 终端中收到消息。

router.get('/registration', async () => {
    console.log('REG')
})

但是在浏览器控制台中我遇到了同样的错误Failed to load resource: the server responded with a status of 404 (Not Found)

请在下面找到我的代码。
服务器.js

const express = require('express');
const mongoose = require('mongoose');
const authRouter = require('./authRouter')//yes
const PORT = process.env.PORT || 5000;
const connectionString = 'mongodb+srv://Ivan:aldaron1@cluster0.fivve.mongodb.net/usersBD?retryWrites=true&w=majority'//yes
const app = express();
app.use(express.json());
app.use(authRouter);
const start = async () => {
    try {
        await mongoose.connect(connectionString)
        app.listen(PORT, () => console.log(`server started on port ${PORT}`))
    } catch (error) {
        console.log(error)
    }
}

start()

authController.js

class authController {
    async registration(req, res) {
        try {
            res.json("server works")
            console.log(" 123 ")
        } catch (e) { }
    }
    async login(req, res) {
        try {
            res.json("server works")
            console.log(" 123 ")
        } catch (e) { }
    }
    async getUsers(req, res) {
        try {
            res.json("server works")
            console.log(" 123 ")
        } catch (e) { }
    }

}

module.exports = new authController();

authRouter.js

const Router = require('express')
const router = new Router()
//const controller = require('./authController')


router.get('/registration', async () => {
    console.log('REG')
})
router.get('/login', async () => {
    console.log('REG')
})
//router.post('/login',)
//router.get('/users', controller.getUsers)

module.exports = router

包.json

任何人为什么会这样？
