创建用户时 Passport-local 超时（Node、Express、Postgres、Knex）

Question

我有一个 Node/Express API 向 Vue 前端提供数据，现在正在添加 Passport 以进行身份验证和授权。我有一个成功添加用户的 createUser 函数，但是这样做时该函数挂起。我敢肯定这只是我错过的一件愚蠢的事情，比如没有打电话给 next()（尽管我这样做了），我很感激有头脑更清醒的人看看。

//authRoutes.js

const router = require('express').Router();
const { createUser } = require('../controllers/authController');

router.route('/auth/register').post(createUser);

module.exports = router;

//authController.js

'use strict';

const authHelpers = require('../auth/_helpers');
const passport = require('../auth/local');

const handleResponse = (res, code, statusMsg) => {
    res.status(code).json({ status: statusMsg });
};

const createUser = (req, res, next) => {
    // passes correct user and pass
    console.log(req.body);
    return authHelpers
        .createUser(req, res, next)
        .then(() => {
            passport.authenticate('local', (err, user, info) => {
                if (err) {
                    handleResponse(res, 500, 'error');
                    console.log(info);
                }
                if (user) {
                    handleResponse(res, 200, 'success');
                    console.log(info);
                }
            })(req, res, next);
        })
        .catch(next);
};

module.exports = {
    createUser,
};

//auth/_helpers.js

const bcrypt = require('bcryptjs');
const knex = require('../db/connection');

const comparePass = (userPassword, databasePassword) =>
    bcrypt.compareSync(userPassword, databasePassword);

const createUser = req => {
    const salt = bcrypt.genSaltSync();
    const hash = bcrypt.hashSync(req.body.password, salt);
    return knex('users')
        .insert({
            email: req.body.email,
            password: hash,
        })
        .returning('*');
};

module.exports = {
    comparePass,
    createUser,
};

根据@cantuket 的建议，记录 createUser 正在 returning 生成用户对象，该对象正确插入到数据库中：

//console.log('res: ', 结果)

{ id: 30,
    email: 'boooya@dubay.com',
    password:
     'a$WNX.9ur7PlS9ZZvZlJk9Tu9j3lWMjaTlUQ1v7i84dqgHscDupIowW',
    admin: false,
    created_at: 2019-03-01T18:22:53.120Z,
    updated_at: 2019-03-01T18:22:53.120Z,
    last_login: null } 
    ```

EDIT 2:
Thanks to [@cantuket][1] for reminding me to get dirty with console logs, I figured it out by switching 'user' with the returned value (here response), and returning nexts. See below for the fix that worked:

不是答案：

我要做的第一件事是检查 createUser() -> knex().insert() 返回了什么...

 .then(result => {
     console.log('createUser:', result)
        passport.authenticate('local', (err, user, info) => {
            if (err) {
                handleResponse(res, 500, 'error');
                console.log(info);
            }
            if (user) {
                handleResponse(res, 200, 'success');
                console.log(info);
            }
        })(req, res, next);
    })
    .catch(err=> {
       console.log('err createUser:', err)
       next();
    });

我可以看到您正在验证护照而不是注册用户。确保在您的主要条目文件中使用护照，app.js 像这样。

    const passport = require('passport')

    app.use(passport.initialize())
app.use(passport.session())
passport.use(User.createStrategy()) 
passport.serializeUser((user, done)=>done(null, user.id)); 
passport.deserializeUser((id, done)=>User.findById(id, (err, user)=>done(err,  user)))
                         
app.use((req, res, next)=>{
    res.locals.currentUser = req.user;
    res.locals.title = 'Conforti';
    res.locals.success = req.session.success || '';
    delete req.session.success;
    res.locals.error = req.session.error || ''; 
    delete req.session.error;
    res.locals.csrfToken= req.csrfToken(); 
    req.session.cookie.expires = new Date(Date.now() + 3600000)
    req.session.cookie.maxAge = 3600000
    next();
    });

在您的控制器中，您应该导入用户模型并像这样对其进行身份验证：

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

这是登录后函数：

postLogin: async (req, res, next)=>{   
   const {username, password} = req.body;
   const {user, error} = await User.authenticate()(username, password);
   if(!user && error) return next(error);
   req.login(user, (err)=>{
     if(err) return next(err);
     req.session.success = `Welcome back, ${user.username}`;
     const redirectUrl = req.session.redirectTo || '/';
     delete req.session.redirectTo;
     res.redirect(redirectUrl);
    
   });
  },

这可能不是完整的代码，但它可能会帮助您发现错误。

您还可以在 npmjs.com
