如何在Bluemix上通过node.js应用程序使用单点登录

Question

我不明白问题出在哪里。我阅读了一些教程和SSO文档。我总是有同样的问题:我的应用程序无法启动。我的应用程序和我的服务绑定得很好。

cf push

下面是错误：error

然后当我使用cf日志时：

cf logs sso-8

响应图片：Error 1/3

下面是我的代码：

//package.json

var app = express();

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

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

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

var services = JSON.parse(process.env.VCAP_SERVICES || "{}");

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

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

app.get('/logout', function(req, res){
    req.logout();
    res.redirect('/');
});

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

app.get('/', function (req, res) {
    res.send('<h1>Bluemix Service: Single Sign On</h1>' + '<p>Sign In with a Social Identity Source (SIS): Cloud directory, Facebook, Google+ or LinkedIn.</p>' + '<a href="/auth/sso/callback">Sign In with a SIS</a>');
});

var appport = process.env.VCAP_APP_PORT || 8888;
var host = (process.env.VCAP_APP_HOST || 'localhost');
var server = app.listen(appport, function () {
    var host = server.address().address
    var port = server.address().port
    console.log('Example app listening at http://%s:%s', host, port);
});

首先需要将应用程序推送到Bluemix并运行，然后才能将SSO服务绑定到它。

将应用程序推送到Bluemix并暂存然后您需要创建未绑定的SSO服务，当SSO服务完全创建和配置后，您可以将其绑定到应用程序。
