我创建了这个passportAuth.js
身份验证文件:
module.exports = function(passport, FacebookStrategy, config, mongoose, fbgraph){
passport.serializeUser(function(user,done){ //make the user reference available threw multiple pages
done(null,user.id);
});
passport.deserializeUser(function(id,done){
userModel.findById(id, function(err, user){
done(err, user);
})
})
passport.use(new FacebookStrategy({
clientID: config.fb.appID,
clientSecret: config.fb.appSecret,
callbackURL: config.fb.callbackURL,
profileFields: ['id', 'displayName', 'photos', 'birthday', 'events', 'profileUrl', 'emails', 'likes']
}, function(accessToken, refershToken, profile, done){
var fb = new fbgraph.Facebook(accessToken, 'v2.2');
fb.me(function(err, me) {
console.log(me);
});
fb.my.events(function(err, events) {
console.log(events);
});
fb.my.friends(function(err, result){
console.log(result);
});
}))
}
直到这里一切正常,我能够用我想要的数据创建fb
var。当我尝试将此fb对象传输到routes.js
文件中的快速路由器时,问题就开始了。我想将存储在此对象中的数据呈现到welcome.html
页面中,但我无法弄清楚如何将此var传递给routes文件并将其传递给render函数。
这是我的路线文件的样子:
module.exports = function(express, app, passport){
var router = express.Router();
router.get('/', function(req,res,next){
res.render('index', {title: "welcome to aDating"});
})
function securePages(req, res, next){
if(req.isAuthenticated()){
next();
} else {
res.redirect('/');
}
}
router.get('/auth/facebook', passport.authenticate('facebook', { scope: [ 'email', 'user_friends', 'public_profile', 'user_events' ] }));
router.get('/auth/facebook/callback', passport.authenticate('facebook', {
successRedirect:'/welcome', //if authentication is successful, navigate to this path
failureRedirect:'/' //else, navigate here
}))
router.get('/welcome', securePages, function(req, res, next){
res.render('welcome', {title:'Welcome to aDating', user:req.user, ----PASS fb HERE--});
})
}
有什么帮助吗?
答案 0 :(得分:1)
尝试passReqToCallback: true
,向req对象添加内容,并在以后的中间件中使用
小心!在请求/响应周期结束后,这将清除!所以例如如果您在req.tmpPassport
的请求中设置/oauth/start
,并且重定向到Facebook并返回/oauth/end
,则req.tmpPassport
将再次未定义。如果您需要跟踪重定向内容,请改用req.session
。
passport.use(new FacebookStrategy({
passReqToCallback: true,
clientID: config.fb.appID,
clientSecret: config.fb.appSecret,
callbackURL: config.fb.callbackURL,
profileFields: ['id', 'displayName', 'photos', 'birthday', 'events', 'profileUrl', 'emails', 'likes']
}, function(req, accessToken, refershToken, profile, done){
req.tmpPassport = {};
var fb = new fbgraph.Facebook(accessToken, 'v2.2');
fb.me(function(err, me) {
req.tmpPassport.me = me;
});
fb.my.events(function(err, events) {
req.tmpPassport.events = events;
});
fb.my.friends(function(err, result){
req.tmpPassport.results = results;
});
}))
