路由

router.post('/login', require('../app/controller/admin/login').login);

控制器

let BaseController = require('../BaseController');

class Login extends BaseController {
    // 登陆
    login() {
        console.log(this.req); // undefiend
    }
}

// here here here here here here
module.exports = new Login(req, res, next);

基类

class BaseController {

    constructor(req, res, next) {

        console.log('-------------', req);

        this.req  = req;
        this.res  = res;
        this.next = next;
        this.data = req.body || req.query; // 获取所有数据
    }
}
module.exports = BaseController();

请问下大家 路由的req 等参数怎样传入控制器里，在导入模块的时候 new Login(req, res, next)???

谢谢大家
