[英]Passport authentication callback hangs
After hours trying to solve this by myself I reach to SO community looking for some light. 经过几个小时试图自己解决这个问题,我到了SO社区寻找一些亮点。
I'm using passport for user authentication. 我正在使用护照进行用户身份验证。 It's already initialized in my main express.js file as per the docs:
它已根据文档在我的主要express.js文件中初始化:
app.use(passport.initialize());
I got a index.js file which handles facebook-passport
in this manner: Index.js 我有一个index.js文件以这种方式处理
facebook-passport
:Index.js
'use strict';
import express from 'express';
import passport from 'passport';
import auth from '../auth.service';
let router = express.Router();
//this function is defined in the auth.service import but copied it here in case it's needed (the `signToken` is also defined in the service)
function setTokenCookie(req, res) {
if (!req.user) return res.json(404, { message: 'Something went wrong, please try again.'});
var token = signToken(req.user._id, req.user.role);
res.cookie('token', JSON.stringify(token));
res.redirect('/');
}
router
.get('/', passport.authenticate('facebook', {
scope: ['email', 'user_about_me'],
failureRedirect: '/login'
}))
.get('/callback', passport.authenticate('facebook', {
successRedirect: '/',
failureRedirect: '/login'
}), setTokenCookie);
module.exports = router;
And the passport.js that's being imported in the index.js in this manner: 以这种方式在index.js中导入的passport.js:
passport.js passport.js
import passport from 'passport';
import {
Strategy as FacebookStrategy
}
from 'passport-facebook';
exports.setup = function(User, config) {
passport.use(new FacebookStrategy({
clientID: config.facebook.clientID,
clientSecret: config.facebook.clientSecret,
callbackURL: config.facebook.callbackURL
},
function(accessToken, refreshToken, profile, done) {
User.findOne({
'facebook.id': profile.id
}, (findErr, user) => {
if (findErr) {
return done(findErr);
}
if (!user) {
let userToSave = new User({
name: profile.displayName,
email: profile.emails[0].value,
role: 'user',
username: profile.username,
provider: 'facebook',
facebook: profile._json
});
userToSave.save((saveErr) => {
if (saveErr) done(saveErr);
return done(null, user);
});
} else {
return done(null, user);
}
});
}
));
};
This is what currently happens: 这是目前发生的事情:
Where things get weird: 事情变得奇怪:
done(null,user)
does nothing. done(null,user)
不执行任何操作。 The app hangs on the callback and client keeps waiting for response. What I've tried: 我尝试过的:
passport.js
in a process.tick (found some people use it but didn't resolve the issue) passport.js
的整个设置功能(发现有些人使用它但没有解决问题) User.findOne({...}).exec().then(user => {...})
User.findOne({...}).exec().then(user => {...})
使用带有promise的Mongoose User.findOne({...}).exec().then(user => {...})
If you need additional information please don't hesitate to ask. 如果您需要其他信息,请不要犹豫。 Any help is really appreciated.
任何帮助都非常感谢。
Thanks! 谢谢!
I see a few possible missing pieces glancing at my code. 我看到一些可能丢失的部分看了我的代码。 Are you using the
passport.session()
middleware? 你使用的是
passport.session()
中间件吗? Also the serializeUser
and deserializeUser
functions? serializeUser
和deserializeUser
函数也是?
passport.serializeUser(function(user, done) {
//place user's id in cookie
done(null, user.id);
});
passport.deserializeUser(function(id, done) {
//retrieve user from database by id
User.findById(id, function(err, user) {
done(err, user);
});
});
If you're a noob to passport/express like me, this may help: 如果你是像我这样的护照/快递菜鸟,这可能会有所帮助:
check if you invoke done() in your passport logic: 检查你是否在护照逻辑中调用done():
passport.use(new twitchStrategy({
clientID: config.twitchID,
clientSecret: config.twitchSecret,
/*to be updated*/
callbackURL: config.callbackURL,
scope: "user_read"
},
function(accessToken, refreshToken, profile, done) {
console.log(profile);
***return done();***
}
));
