没有调用nodejs护照回调

Question

我对 JS 和 NodeJs/Express 都很陌生。我正在编写一个概念验证 MVP node/express 应用程序，它使用护照进行身份验证（通过社交登录）。

我已经编写了服务器并安装了所有必需的包和到目前为止的一切（除了身份验证位工作）。

注意：我已经在各个社交媒体公司的端设置了我的凭据，所以这不是问题。

这是我的代码片段：

app.js

const express = require('express');
const expressLayouts = require('express-ejs-layouts');
compression = require('compression'),
shouldCompress = (req, res) => {
    if (req.headers['x-no-compression']) {
      // don't compress responses if this request header is present
      return false;
    }
    // fallback to standard compression
    return compression.filter(req, res);
  };

const app = express();

// EJS
app.use(expressLayouts);
app.set('view engine', 'ejs');

// Parsing related
app.use(express.urlencoded( { extended: false })); //Parse URL-encoded bodies
app.use(express.json()); //Used to parse JSON bodies

app.use(compression({
    filter:shouldCompress,
    threshold: 3
}));

app.use(express.static('public'));
app.disable('x-powered-by');

// Initialize Passport and restore authentication state, if any, from the session.
var passport = require('passport');
app.use(require('express-session')({ secret: 'keyboard cat', resave: false, saveUninitialized: false }));
app.use(passport.initialize());
app.use(passport.session())

// Routes
app.use('/', require('./routes/index'));
app.use('/member', require('./routes/users'));


const PORT = process.env.PORT || 5000;

app.listen(PORT, console.log(`Server started on port: ${PORT}`));

routes/users.js

const express = require('express');
const router = express.Router();

/* GET authentication funcs */
let authentication = require('../controllers/auth.js');

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

module.exports = router;

controllers/auth.js

require('dotenv').config();
const model = require("../models");

const passport = require('passport');

const LocalStrategy = require('passport-local').Strategy;
const FacebookStrategy = require('passport-facebook').Strategy;

passport.serializeUser(function(user, done) {
    done(null, user)
});


passport.deserializeUser(function(email, done) {
    done(null, email)
})


function validateLead(req, done) {
    mail = req.body.lead_email;
    console.log('validateLead() called!');

    models.Lead.findOne({
        where: {
            email: email
        }
    }).then(/* some logic */).catch();
        } else {
            // email already taken ..
            return done(null, false, {
                message: 'This email address is already subscribed'
            });
        }
    }).catch((err) => {
        console.log('An error occurred!', err);
    });
}

exports.subscribe = function(req, res, next) {
    switch (req.body.source) {
        case 'facebook':
            passport.use(new FacebookStrategy({
                    clientID: process.env.FACEBOOK_APP_ID,
                    clientSecret: process.env.FACEBOOK_APP_SECRET,
                    callbackURL: process.env.FACEBOOK_CALLBACK_URL
                },
                function(accessToken, refreshToken, fbProfile, done) {
                    console.log('FB callback!');
                    profile = {
                        'email': fbProfile.email,
                        'firstName': '',
                        'LastName': '',
                        'leadSource': '',
                        'tags': [],
                    };
                    return validateLead(req, done, profile);
                }
            ));
            break;
        default:
            console.log('Unknown');
      }
}

views/test.eps

<a href='#'><i id='facebook' class='foobar'></i></a>

（简体）views/layout.eps

   $(document).ready(function(){
      $('i.foobar').click(function(e){
        $.ajax({
          method: "POST",
          url: "/member/subscribe",
          data: {
            "source": $(this).attr('id')
          },
          dataType: "json",
          timeout: 5000 // 5000ms
        }).done(function(data) {
          // is called if request is successful
          console.log(data.fridge);
        }).fail(function(jqXHR, status) {
          // is called if request fails or timeout is reached
          alert('Request could not complete: ' + status);
        });
      });
    });

我已将 console.log() 消息放入 controllers/auth.js 中，我可以看到正在到达 FB 代码分支。但是，当 validateLead() 中的日志消息和 FB 回调函数未到达时。

这是什么原因，我该如何解决？

Answer 1

我能看到几件事：

据我所知，您没有配置 passportjs。您需要有一个配置文件，对您来说就是 controllers/auth.js。要配置通行证，您需要运行 require('./controllers/auth')(passport); in app.js.

为了使 passport 能够摄取该配置，您需要将它们导出为接受 passport 的函数，例如module.exports = passport => {passport.use('facebook')}

您的配置文件（在 exports.subscribe 中）不是 passport 可以理解的格式。按照有关如何创建该配置文件的文档进行操作。

Passport 为您提供身份验证 中间件，我很确定您不能像 controllers/auth.js 那样为它们创建 "wrappers"。要访问护照的身份验证功能，您可以在 routes/users.js 中使用 passport.authenticate('facebook', callback())(req, res, next)。

Passport 只提供中间件来序列化和反序列化用户。

您的反序列化尚未设置。您需要调用数据库以从会话存储中获取用户。
