Bluemix上的Node.JS - 附加SSO失败

Question

我正在使用IBM Bluemix平台，并试图在超级基本节点JS应用程序的顶部添加SSO登录页面作为安全性。我本指南来过这里以下：https://www.ng.bluemix.net/docs/services/SingleSignOn/index-gentopic2.html#task_configuringapp

但是，我得到的是一个错误：“不能GET /”

这是我的app.js代码：

var express = require('express'); 
var passport = require('passport'); 
var cookieParser = require('cookie-parser'); 
var session = require('express-session'); 
var cfenv = require('cfenv'); 

//create a new express server 
var app = express(); 

// SSO 

app.use(cookieParser()); 
app.use(session({resave: 'true', saveUninitialized: 'true' , secret: 'keyboard cat'})); 
app.use(passport.initialize()); 
app.use(passport.session()); 

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

passport.deserializeUser(function(obj, done) { 
    done(null, obj); 
});   

// VCAP_SERVICES contains all the credentials of services bound to 
// this application. For details of its content, please refer to 
// the document or sample of each service. 
var services = JSON.parse(process.env.VCAP_SERVICES || "{}"); 
var ssoConfig = services.SingleSignOn[0]; 
var client_id = ssoConfig.credentials.clientId; 
var client_secret = ssoConfig.credentials.secret; 
var authorization_url = ssoConfig.credentials.authorizationEndpointUrl; 
var token_url = ssoConfig.credentials.tokenEndpointUrl; 
var issuer_id = ssoConfig.credentials.issuerIdentifier; 
var callback_url = 'https://sso-test-6.mybluemix.net/auth/sso/callback';   

var OpenIDConnectStrategy = require('passport-idaas-openidconnect').IDaaSOIDCStrategy; 
var Strategy = new OpenIDConnectStrategy({ 
       authorizationURL : authorization_url, 
       tokenURL : token_url, 
       clientID : client_id, 
       scope: 'openid', 
       response_type: 'code', 
       clientSecret : client_secret, 
       callbackURL : callback_url, 
       skipUserProfile: true, 
       issuer: issuer_id}, 
    function(iss, sub, profile, accessToken, refreshToken, params, done) { 
       process.nextTick(function() { 
     profile.accessToken = accessToken; 
     profile.refreshToken = refreshToken; 
     done(null, profile); 
      }) 
}); 

passport.use(Strategy); 
app.get('/login', passport.authenticate('openidconnect', {})); 

function ensureAuthenticated(req, res, next) { 
    if(!req.isAuthenticated()) { 
       req.session.originalUrl = req.originalUrl; 
     res.redirect('/login'); 
    } else { 
     return next(); 
    } 
} 

app.get('/auth/sso/callback',function(req,res,next) {    
    var redirect_url = req.session.originalUrl;     
    passport.authenticate('openidconnect', { 
      successRedirect: redirect_url,         
      failureRedirect: '/failure',       
})(req,res,next); 
}); 

app.get('/failure', function(req, res) { 
    res.send('login failed'); }); 

//get the app environment from Cloud Foundry 
var appEnv = cfenv.getAppEnv(); 

// start server on the specified port and binding host 
app.listen(appEnv.port, function() { 

    // print a message when the server starts listening 
    console.log("server starting on " + appEnv.url); 
}); 

我感觉就像我在做一件非常愚蠢的事情？但我无法弄清楚 -

您需要定义路由'/'，然后重定向用户登录。

例如：

app.get('/', function(req, res) { 
     res.send('Single Sign On <a href="/login">Login</a>\n'); 
    }); 

你可以看到在下面的链接一个很好的例子：
