mysql - 类型错误：无法读取未定义的属性“护照”

问题描述

我是护照新手并且遇到了这个问题，所以这可能是护照的一个非常基本的开发错误，我正在做的优先级是在 index.js 中：

const express = require('express');
const router = express.Router();
const bodyParser = require('body-parser');
var jsonParser = bodyParser.json()

const passport = require('passport')

// create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })

const connection = require('../../database/db.js');

router.get('/', (req, res) => {
res.render('user');
});

router.get('/login', (req, res) => {
res.render('login');
});

router.get('/home', (req, res) => {
res.send('hola');
});

router.post('/login', passport.authenticate('local.signup', {
successRedirect: '/home',
failureRedirect: '/login',
failureFlash: true
}));

module.exports = router;

而我的主文件是app.js，我在其中做passport.session，passport.json，所以这可能是错误“passport”未定义：

const express = require('express');
const morgan = require('morgan');
const path = require('path');
const app = express();
require('./lib/passport.js')

const mysql = require('mysql');
const myConnection = require('express-myconnection');
const session = require("express-session");

const passport = require('passport');

// settings
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.urlencoded({extended: false}));
app.use(express.json());
app.use(passport.initialize());
app.use(passport.session());


// middlewares
app.use(morgan('dev'));

// routes
app.use(require('./routes'));

// static files
app.use(express.static(path.join(__dirname, 'public')));

// listening the Server
app.listen(app.get('port'), () => {
console.log('Server on port', app.get('port'));
});

最后，我得到控制台的错误，但如果我无法读取错误：

解决方案

我认为，您的问题与护照会议有关。您需要在它之前使用 express session 才能正常工作。
