Passport.js twitter 身份验证导致 500 错误，req.session 未定义答案

【问题标题】：Passport.js twitter authentication causing 500 error, req.session is undefinedPassport.js twitter 身份验证导致 500 错误，req.session 未定义

【问题描述】：

我正在尝试使用 passport-twitter 在 Node 应用程序中设置会话，以便我可以保留用户数据，但据我所知，我无法打开会话支持。此外，我确保回调函数与 Twitter Developers 上的应用程序条目匹配。程序抛出的500错误是：

500 Error: OAuthStrategy requires session support. Did you forget app.use(express.session(...))?**
    at Strategy.OAuthStrategy.authenticate (/Users/xxxxxxxx/web/Node/on/node_modules/passport-twitter/node_modules/passport-oauth1/lib/strategy.js:120:41)
    at Strategy.authenticate (/Users/xxxxxxxx/web/Node/on/node_modules/passport-twitter/lib/strategy.js:85:40)
    ....

当我在第 120 行检查 strategy.js 时，它说：

if (!req.session) { return this.error(new Error('OAuthStrategy requires session support. Did you forget app.use(express.session(...))?')); }

所以，显然 req.session 是未定义的。但是，我认为我已经完成了使会话支持正常工作所需的一切。这是我的大部分主服务器 js 文件：

var express = require('express'),
app = express();

var http = require('http'),
https = require('https');

var mongodb = require('mongodb'),
mongoose = require('mongoose');

var passport = require('passport'),
TwitterStrategy = require('passport-twitter').Strategy,
imon = require('./imon'),
routes = require('./routes')(app),
user = require('./models/user'),
group = require('./models/group'),
song = require('./models/song'),
album = require('./models/album'),
activity_item = require('./models/activity_item');

app.set('env', 'development');

console.log("app.get('env') =", app.get('env'));
console.log(app.get('env') === 'development');

// development only
if (app.get('env') === 'development') {
    app.set('views', __dirname + '/views');
    app.use(express.logger('dev'));
    app.use(express.bodyParser());
    app.use(express.methodOverride());
    app.use(express.cookieParser('secret'));
    app.use(express.cookieSession());
    app.use(passport.initialize());
    app.use(passport.session());
    app.use(app.router);
    app.use(express.errorHandler());
}

// production only
if (app.get('env') === 'production') {
  // TODO
}


// all environments


mongoose.connect('mongodb://localhost/test');
var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function callback () {
  console.log('Connected to DB');
});


passport.use(new TwitterStrategy({
    consumerKey: "0GOReNaXWXCTpf7OQgrg",
    consumerSecret: "0wA8yUBrXz3ivpTHcuBbKp3vGN2ODnOF7iFM9DB48Y",

  },
    function(token, tokenSecret, profile, done) {
        console.log("THis gets called?");
        function sanitizeImgURL(string){
            return string.replace("_normal", "");
        }

        console.log("profile: ", profile);
        process.nextTick(function(){
            User.find({account: {id: profile.id}}, function(err, user) {
                if(err){
                    return done(err);
                }
                if(!user){
                    return done(null, false, { message: 'Incorrect password.' });
                }
                else if(user){
                    done(null, user);
            }
            var newUser = new User(
                {account:
                    {provider: profile.provider,
                    id: profile.id},
                username: profile.username,
                displayName: profile.displayName,
                email: profile.email,
                image: sanitizeImgURL(profile._json.profile_image_url)
            });
            return done(null, newUser);
        });
    });
    }
));

passport.serializeUser(function(user, done) {
    console.log("SERIALIZE: ", user);
  done(null, user);
});

passport.deserializeUser(function(obj, done) {
    console.log("DESERIALIZE: ", obj);
  done(null, obj);
});


/**

// Redirect the user to Twitter for authentication.  When complete, Twitter
// will redirect the user back to the application at

app.get('/auth/twitter', passport.authenticate('twitter'));

// Twitter will redirect the user to this URL after approval.  Finish the
// authentication process by attempting to obtain an access token.  If
// access was granted, the user will be logged in.  Otherwise,
// authentication has failed.
app.get('/auth/twitter/callback',
  passport.authenticate('twitter', { successRedirect: '/static/index.html',
                                     failureRedirect: '/static/login.html' }));

...一些路线...

app.listen(8888);

【解决方案1】：

我想通了；这是两件事：

1.)connect-redis 中断了会话，仍然不知道为什么，但是在我之后删除它解决了我的问题...

2.)... 移动了我的 require routes 行，该行将 app 对象作为我的 app.use 语句之后的参数。现在说得通了，我在将我的 app 对象传递给我的 routes 之前，我使用了诸如，我不知道，SESSIONS 之类的东西来配置它。
