护照 - 发送后无法设置 headers

Question

我正在制作一个登录模块，但每当我输入错误的电子邮件和密码（经过哈希处理，因此我需要将明文转换为哈希）时，它仍然会通过并在我的节点模块上显示此错误：

Error: Can't set headers after they are sent.
at validateHeader (_http_outgoing.js:491:11)

我的护照代码是：

const bcrypt = require('bcrypt')
const localStrategy = require('passport-local').Strategy;
const mongoose = require('mongoose');

const User = require('../models/usrschema')

module.exports = function(passport){
  passport.use(
    new localStrategy({ usernameField: 'email'}, ( email, password, done) =>  {
      User.findOne({email: email})
      .then(user => {
        if(!user){
          return done(null, false, {});
        }

        bcrypt.compare(password, user.password, (err, isMatch) => {
          if(err) throw err;
          if(isMatch){
            return done(null, user);
          } else {
            return done(null, false);
          }
        });

      })
      .catch(err => console.log(err))
    })
  );
  //fsdfdsfds
  passport.serializeUser ((user, done) => {
    done(null, user.id)
  });

  passport.deserializeUser ((id, done) => {
    User.findById(id, (err, user) => {
      done(err, user)
    })
  })

}

抱歉，我很忙.. 在我的登录路由器文件中，

pgroutr.post('/', (req, res, next) => {
  const emailog = req.body.email;
  var obj = {emaill: emailog}
  passport.authenticate('local', {
    // successRedirect: res.render('profile', obj), <- replace this with
       successRedirect: '/profile', //<----- this
    failureRedirect: '/'
  })(req, res, next);

})
