Node.js中利用中间件处理错误案例

error.js

const express = require('express');
let app = express();

app.get("/index", (req, res) =>{
    res.send("index")
})

app.get("/login", (req, res) =>{
    res.send("login")
})

// set middleware to handle error
app.use((req, res) =>{
    res.status(404).send("<h1>404 Not Found</h1>")
})

app.listen(3000, ()=>{
    console.log("Port 3000 is listening...")
})
