express在router中使用express对象

Question

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

app.use();    // 想在这里调用express对象

router.get('/aa', function (req, res, next) {
    res.send('aaaaa');
});

请问一下 我应该怎么在路由中访问app对象？

Answer 1

express#req.app

Answer 2

也可以把app作为参数传到 router的函数里

module.exports = function(app){
    var router = express.Router();
    router.get('/aa', function (req, res, next) {
    res.send('aaaaa');
});
}
