Question

const express = require('express');

let router = express.Router();


router.get('/add-product',(req, res, next)=>{
    res.send('<form action="/try" method="POST"><input type="text" name="title"><button type="submit">Sub,it</button> </form>');

});

package.json “依赖项”：{

"body-parser": "^1.19.0",

"express": "^4.17.1",

"funding": "^1.0.9"

它显示错误“无法解析的函数或方法get（）” 我什至安装了express和body-parser

Answer 1

您应该使用express而不是express.Router()

let router = express();

Answer 2

如果示例无法帮助您，请指定您的应用启动文件

const express = require('express');
const bodyParser = require('body-parser');

const app = express();

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.use(express.static('public'));

const routerProducts = express.Router()

// middleware that is specific to this router
routerProducts.use(function timeLog (req, res, next) {
  console.log('Time: ', Date.now())
  next()
})

// define the add-product route
routerProducts.post('/add-product', function (req, res) {
  res.send('products create')
})

// define the get-product route
routerProducts.get('/get-product', function (req, res) {
  res.send('products get')
})
app.use('/products', routerProducts )
app.listen(3000, () => console.log('server started'));

致电GET：http://127.0.0.1:3000/products/get-product

app.get在Express Node JS中不起作用
