var express =require(‘express‘);
var router =express.Router();

router.post(‘/‘,function(req,res,next){
var msg = req.body.msg;
    if(msg){

});

module.exports = router;

var loginmsg = require(‘./routes/loginmsg‘);

//模板引擎设置
app.set(‘views‘, path.join(__dirname, ‘views‘));
app.set(‘view engine‘, ‘jade‘);
app.use(express.static(‘public‘));

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

//设置路由
app.use(‘/‘,login);
app.use(‘/loginmsg‘,loginmsg);

app.listen(3000);
console.log("启动端口:3000");
