express与express-art-template两者相结合使用方法

var express = require('express');

var app = express();

var comments = [
    {
        name:'姓名',
        message:'你好呀',
        dateTime:'2018-12-12'
    }
]

app.set('views','./common/');

app.engine('html', require('express-art-template'));

app.set('view options', {
    debug: process.env.NODE_ENV !== 'production'
});


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


app.get('/',function(req,res){
    //express会到默认的views目录下去找该文件
    //修改默认views目录，app.set('views','./common/')
    res.render('index.html', {
        comments:comments
    })
});

app.get('/post',function(req,res){
    res.render('post.html');
});

app.get('/ping',function(req,res){
    var common = req.query;
    common.dateTime = '2018-12-12';
    comments.unshift(common);
    res.redirect('/');
})

app.listen(3000,function(){
    console.log('running...');
})
