错误：Route.post需要回调函数，但得到了[object Object]

问题描述

我正在尝试在Web应用程序中实现密码重置功能，但标题中始终出现错误。我的代码：

main.js：

const router = express.Router();
const AsyncNewPassword = require('./controller/asyncnewpassword');
const ResetPassWord = require ('./controller/resetpassword');
const ValidPasswordToken = require ('./controller/validpasswordtoken');
...
router.post('/req-reset-password',function (req,res) { ResetPassWord });
router.post('/new-password',res) { AsyncNewPassword });
router.post('/valid-password-token',res) { ValidPasswordToken });

asyncnewpassword.js：

module.exports.NewPassword = async function NewPassword(req,res) {
    passwordResetToken.findOne({ resettoken: req.body.resettoken },function (err,userToken,next) {
      if (!userToken) {
        return res
          .status(409)
          .json({ message: 'Token has expired' });
      }

      User.findOne({
        _id: userToken._userId
      },userEmail,next) {
        if (!userEmail) {
          return res
            .status(409)
            .json({ message: 'User does not exist' });
        }
        return bcrypt.hash(req.body.newPassword,10,(err,hash) => {
          if (err) {
            return res
              .status(400)
              .json({ message: 'Error hashing password' });
          }
          userEmail.password = hash;
          userEmail.save(function (err) {
            if (err) {
              return res
                .status(400)
                .json({ message: 'Password can not reset.' });
            } else {
              userToken.remove();
              return res
                .status(201)
                .json({ message: 'Password reset successfully' });
            }

          });
        });
      });

    })
}

resetpassword.js：

module.exports.ResetPassword = async function ResetPassword(req,res) {
    if (!req.body.email) {
    return res
    .status(500)
    .json({ message: 'Email is required' });
    }
    const user = await User.findOne({
    email:req.body.email
    });
    if (!user) {
    return res
    .status(409)
    .json({ message: 'Email does not exist' });
    }
    var resettoken = new passwordResetToken({ _userId: user._id,resettoken: crypto.randomBytes(16).toString('hex') });
    resettoken.save(function (err) {
    if (err) { return res.status(500).send({ msg: err.message }); }
    passwordResetToken.find({ _userId: user._id,resettoken: { $ne: resettoken.resettoken } }).remove().exec();
    res.status(200).json({ message: 'Reset Password successfully.' });
    var transporter = nodemailer.createTransport({
      service: 'Gmail',port: 465,auth: {
        user: 'user',pass: 'password'
      }
    });
    var mailOptions = {
    to: user.email,from: '[e-mail]',subject: 'Node.js Password Reset',text: 'You are receiving this because you (or someone else) have requested the reset of the password for your account.\n\n' +
    'Please click on the following link,or paste this into your browser to complete the process:\n\n' +
    'http://localhost:4200/response-reset-password/' + resettoken.resettoken + '\n\n' +
    'If you did not request this,please ignore this email and your password will remain unchanged.\n'
    }
    transporter.sendMail(mailOptions,info) => {
    })
    })
    }

validpasswordtoken.js：

module.exports.ValidPasswordToken = async function ValidPasswordToken(req,res) {
    if (!req.body.resettoken) {
    return res
    .status(500)
    .json({ message: 'Token is required' });
    }
    const user = await passwordResetToken.findOne({
    resettoken: req.body.resettoken
    });
    if (!user) {
    return res
    .status(409)
    .json({ message: 'Invalid URL' });
    }
    User.findOneAndUpdate({ _id: user._userId }).then(() => {
    res.status(200).json({ message: 'Token verified successfully.' });
    }).catch((err) => {
    return res.status(500).send({ msg: err.message });
    });
};

我的堆栈跟踪：

最初，该代码在路由器的第二个参数中没有函数包装，但是我添加了它，从那时起，访问它时将找不到URL ...

解决方法

您可以尝试：

router.post('/req-reset-password',ResetPassWord);

这应调用方法ResetPassword。
请注意：用resetPassword改正骆驼肠衣。

编辑：

也许您的导入有问题。
试试

module.exports = async function ResetPassword(req,res) {
... 

或者用大括号导入

const { ResetPassWord } = require ('./controller/resetpassword');

编辑2：

由于使用的是nodejs，因此可以使用es6。

在Dependend模块中：

exports.resetPassword = async (req,res) => {
... 

在路由器文件中：

import { restPassword } from './controller/resetpassword';

应该工作，我一直都在使用它。
