Yii2 share session between 2 apps

问题

Currently, my application have the following structure:

frontend
backend (user authenticated)
client (user authenticated)

What I'm trying to do is to pass a flash message from the client to the frontend.

In the client app I simple set the flash:

Yii::$app->session->setFlash('successMessage', 'My success message!');

And in the frontend:

Yii::$app->session->getFlash('successMessage');

But the above obviously is not working.

I've already tried to set equal session id in the config/main.php of both apps, but there seems to be no different:

'components' => [
    'session' => [
        'name' => '_mySharedSessionId',
        'savePath' => __DIR__ . '/../runtime',  
    ],
    ...
]

Any ideas where I'm wrong?

UPDATE The problem maybe came from that I have set 4 different vhosts for each app: local-frontend, local-backend, local-client. If I revert it to the default, all seems to work fine. So my question now is: Is there an universal way to share a session between the above vhosts so that when the site is uploaded for production it will work also there (probably the urls on production will be something like www.mysite.com, www.client.mysite.com, www.admin.mysite.com)?

Add below code in your controller file

Yii::$app->session->setFlash('delete', "Member Deleted Successfully.......");

And add below code in your view or index file

<?php if (Yii::$app->session->hasFlash('delete')): ?>
   <div class="alert alert-danger alert-dismissable">
      <button aria-hidden="true" data-dismiss="alert" class="close" type="button">×</button>
      <h4><i class="icon fa fa-check"></i>Deleted!</h4>
      <?= Yii::$app->session->getFlash('delete') ?>
   </div>
<?php endif; ?>

The issue is in your php configuration and not specific to Yii2. You should explicitly set session.cookie_domain parameter in php.ini:

session.cookie_domain = ".example.com"

Alternatively, you can do that in php using ini_set (for example, in your web/index.php):

ini_set('session.cookie_domain', '.example.com' );

By default, that variable restricts cookies to current domain, but setting it to .example.com (notice the dot prefix) will allow to use the same cookie for example.com, www.example.com, foo.example.com, bar.example.com, but not example.org.

Specifically for your local installation, change vhosts to frontend.local, backend.local, and client.local, and set cookie_domain to .local.

If you want to share the session from one application to another without hindering the domain configuration of the app, then you should try memcache!
