Route/index.js
This is the router.
Const express = require ('express'); const router = express.Router (); / / simulate the home page message list data var comments= {"comments": [{name: "AAA", message: "what editor do you use? WebStorem or VSCODE ", datetime:" 2021-1-1 "}, {name:" BBB ", message:" what a beautiful day? Fishing or Code ", datetime:" 2021-1-1 "}, {name:" Moshow ", message:" zhengkai.blog.csdn.net ", datetime:" 2021-1-1 "}, {name:" DDD ", message:" the difference between and ", datetime:" 2021-1-1 "}, {name:" EEE ", message:" Wang Shouyi thirteen incense or iPhone thirteen incense " Datetime: "2021-1-1"}]} / * by zhengkai.blog.csdn.net-static route hosting * / router.get ('/', function (req, res, next) {res.render ('index', comments) }); router.get ('/ post', function (req, res, next) {res.render ('post', comments);}); router.get (' / say', function (req, res, next) {console.log (req.query) console.log (req.url) const comment=req.query; comment.datetime='2021-10-01; comments.comments.unshift (comment) / / Redirect to the home page without the url suffix localhost res.redirect ('/'); / / render the home page directly with the url suffix localhost/say?xxxx=xxx / / res.render ('index', comments);}); module.exports = router
App.js
Here as total control.
/ / load module const http=require ('http'); const fs=require (' fs'); const url=require ('url'); const template=require (' art-template'); const path = require ('path'); const express = require (' express'); const router = express.Router (); const app = express (); / / view engine setupapp.set ('views', path.join (_ _ dirname,' views'); app.set ('view engine',' html')) App.engine ('html',require (' express-art-template')); app.use ('/ public',express.static (path.join (_ _ dirname, 'public'); const indexRouter = require ('. / routes/index'); app.use ('/', indexRouter) / / create a listening object app.listen (80dint function () {console.log ('zhengkai.blog.csdn.net project started successfully).
