})
//导入前台路由和后台路由
let adminRouter=require('./routers/admin')
let homeRouter=require('./routers/home');
// 使用前台路由
// 参数1：匹配路由规则
// 参数2：请求路由规则
app.use('/',homeRouter)
app.use('/admin',adminRouter)
module.exports = router;1.1.2 Common module configurations for app.js entry files

let ejs=require('ejs')//需要下载
let path=require('path')//nodejs底层自带模块
app.set('views','./views');

app.use('/public',express.static(__dirname+'/public'))
app.use('/upload',express.static(__dirname+'/upload'))
app.use('/images',express.static(__dirname+'/images'))
//导入前台路由和后台路由
let adminRouter=require('./routers/admin')
let homeRouter=require('./routers/home');

app.use('/admin',adminRouter)
//监听服务器
let port=3000
app.listen(port,function(){
console.log('node服务器已经启动，端口是：'+port);
