Passport-创建用户时本地超时(Node、Express、Postgres、Knex)

Question

我有一个向Vue前端提供数据的Node/Express API，现在正在添加用于身份验证和授权的Passport。我有一个createUser函数，它成功地添加了用户，但在这样做时函数挂起。我肯定这只是我错过的一件愚蠢的事情，比如没有调用next()（尽管我已经调用了），我希望有一个头脑更清醒的人看一下。

//authrotes.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,
};

编辑1：

按照@Cantuket的建议,记录createUser返回的内容将生成user对象,该对象将正确地插入到DB中：

//console.log('res:',result)

{ id: 30,
    email: '[e-mail]',
    password:
     '$2a$10$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:

const createUser=（req,res,next）=>{return authHelpers.createUser（req,res）.then（response=>{passport.authenticate（“local”,（err,user,info）=>{if（err）{console.error（err）；console.info（info）；handleResponse(res，500，“错误”）；返回next（err）；}if（！response）{console.error（err）；console.info（info）；handleResponse(res，500，“无用户”）；返回next（err）；}if（响应）{handleResponse(res，200，'success')；next（）；}}）（req,res,next）；}）.catch（err=>{console.error（err）；console.info（info）；handleResponse（res,500,“error”）；return next（err）；}）；}；

我可以看到您正在验证passport而不是已注册的用户。确保在您的主条目文件app.js中使用passport,如下所示。

    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对其进行身份验证,如下所示：

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

这是postLogin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);
    
   });
  },     

这可能不是全部代码，但它可以帮助您发现错误。

您也可以在npmjs.com上查看passport文档

没有回答：

我要做的第一件事是检查createuser()->knex().insert()返回的内容...

 .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();
    });
