如何修復快速路由

Question

router.post('/login', (req, res, next) => {

  User.findOne({ "email": req.body.email }, (err, user) => {
    if (err) throw err;

    if (!user){
        res.json({
            success: false,
            message: 'Authenticated failed, User not found'
        });
    } else if (user) {

        var validPassword = user.comparePassword(req.body.password);
        if (!validPassword) {
            res.json({
                success: false,
                message: 'Authentication failed. Wrong Password'
            });
    } else {
        var token = jwt.sign({
            user: user
            }, config.secret, {
                expiresIn: '7d'
            });

            res.json({
                success: true,
                message: "enjoy your token",
                token: token
            });
        }
    }

});

錯誤：

events.js:180 拋出錯誤； // 未處理的“錯誤”事件 ^ 錯誤 [ERR_UNHANDLED_ERROR]：未處理的錯誤。 (Incorrect arguments) at Function.emit (events.js:178:17) at C:\Users\farid\Desktop\Ecomerce\server\node_modules\mongoose\lib\model.js:4640:13 at C:\Users\ farid\Desktop\Ecomerce\server\node_modules\mongoose\lib\query.js:4345:12 at process.nextTick (C:\Users\farid\Desktop\Ecomerce\server\node_modules\mongoose\lib\query.js:2841 :28) 在 process._tickCallback (internal/process/next_tick.js:61:11)

我不知道我錯過了什么，有人可以突出代碼中的錯誤嗎？

Answer 1

在您的代碼中使用 try catch 塊，希望這會對您有所幫助。
