次のapp.jsコードがあります
app.configure(function(){
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.enable('jsonp callback');
app.set('view engine', 'jade');
app.set('view options', {layout : false});
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser());
app.use(express.session({
secret : 'abcdefg'
}));
app.use(app.router);
app.use(express.static(__dirname + '/public'));
app.use(function(req, res, next){
res.locals.user = req.session.user;
next();
})
});
.jadeビューで次のコードが機能するようにしようとしています
- if(session.user)
div#logoutsection.pull-right
a#logout-btn.btn.btn-info.pull-right.top-bar-form-button(href='logout/') Logout
p#loginprompt.pull-right.login-prompt #{session.user.username} logged In
- else
ul.pull-right
li
a#signup-btn.btn.pull-right.top-bar-form-button(href='#signup-modal', data-toggle="modal") Sign Up
そのため、サインインしていない場合はサインアップするオプションを提供し、サインインしている場合は「ログイン済み」であることを伝えます。app.configure使用する前と同じように、コードの最後に関数を追加しましたが、それが正しい方法dynamicHelpers()であると言われcookieParser()ましたが、ユーザーがログインしているかどうかを確認し、ユーザー名を提供できるようにするには、これをどのようにコーディングしますか?上にしようとしていますか？
どんな助けでも感謝します。
ありがとう！
