中间件在nodejs中不起作用

Question

我有这段代码：

exports.get_transducer_edit = (req, res) => {
    if(req.isAuthenticated()){
        Transducer.findById(req.params.id, (err, foundTransducer) => {
            if(err){
                res.redirect('/en/dashboard');
            } else {
                res.render('dashboard/transducer_edit-dashboard', {transducer: foundTransducer});
            }
        });
    }else{
        req.flash('error','You need to log in to do that');
        res.redirect('/dashboard/login');
    }
};

它运行没有问题，但是当我在middleware / index.js中创建一个中间件时：

var middlewareObj = {};

middlewareObj.isLoggedIn = function(req, res, next){
    if(req.isAuthenticated() ) {
        return next();
    }
    res.redirect('/dashboard/login');
};

module.exports = middlewareObj;

我在这段代码中调用了它：

const middleware = require('../middleware');
const Transducer = require('../models/productTransducers');



exports.get_transducer_edit =  middleware.isLoggedIn, (req, res) => {
        Transducer.findById(req.params.id, (err, foundTransducer) => {
            if(err){
                res.redirect('/en/dashboard');
            } else {
                res.render('dashboard/transducer_edit-dashboard', {transducer: foundTransducer});
            }
        });
    
};

我做错了什么？请帮忙......

抱歉，我刚刚解决了。

我在我的路线中打电话给中间件：

router.get（'/ en / dashboard / products / transducers /：id / edit'，middleware.isLoggedIn，transducer_controller.get_transducer_edit）;

我试图在我的控制器中调用它，如：

exports.get_transducer_edit = middleware.isLoggedIn，（req，res）=＆gt; { ...

错！

再次感谢。
