* Ensure that a user is logged in before proceeding to next route middleware.
|
|
*
|
|
* This middleware ensures that a user is logged in. If a request is received
|
|
* that is unauthenticated, the request will be redirected to a login page (by
|
|
* default to `/login`).
|
|
*
|
|
* Additionally, `returnTo` will be be set in the session to the URL of the
|
|
* current request. After authentication, this value can be used to redirect
|
|
* the user to the page that was originally requested.
|
|
*
|
|
* Options:
|
|
* - `redirectTo` URL to redirect to for login, defaults to _/login_
|
|
* - `setReturnTo` set redirectTo in session, defaults to _true_
|
|
*
|
|
* Examples:
|
|
*
|
|
* app.get('/profile',
|
|
* ensureLoggedIn(),
|
|
* function(req, res) { ... });
|
|
*
|
|
* app.get('/profile',
|
|
* ensureLoggedIn('/signin'),
|
|
* function(req, res) { ... });
|
|
*
|
|
* app.get('/profile',
|
|
* ensureLoggedIn({ redirectTo: '/session/new', setReturnTo: false }),
|
|
* function(req, res) { ... });
|
|
*
|
|
* @param {Object} options
|
|
* @return {Function}
