Passport.js推特身份验证导致500错误，req.session未定义

Question

我正在尝试使用passport-twitter在Node应用程序中设置会话，这样我就可以持久化用户数据，但据我所知，我无法打开会话支持。此外，我还确保回调函数与Twitter开发人员上的应用程序条目相匹配。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)
    ....

当我检查第120行的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，很明显，req.session是未定义的。然而，我想我已经完成了让会话支持工作所需的所有工作。下面是我的主服务器js文件的大部分：

app = express();

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

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

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

                else if(user){
                    done(null, user);
            }
            var newUser = new User(

                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

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' }));

..。有些路线。

app.listen(8888);

我想通了；有两件事：

1.)connect-redis中断了会话，仍然不知道为什么，但删除它修复了我的问题后，我...

2.)...移动了我的“请求路由”行，它将app对象作为参数放在我的app.use语句之后。现在很有意义了，我把app对象传递给我的routes，然后再配置会话之类的东西。
