cakephp3 session deprecated

Question

I have update into my project the last version of cakephp core. Now I get this error:

Deprecated (16384): SessionHelper has been deprecated. Use request->session() instead. [CORE/src/View/Helper/sessionHelper.php, line 39]

The error I think is in this line:

if ($this->session->read('admin_logged_in')){

What should I use instead?

Thanks

Answer 1

if ($this->request->session->read('admin_logged_in')){

should be fine.

UPDATE

As per the comment of @raph below the correct answer is

$this->request->session()->read('admin_logged_in')

Note the () after session

Answer 2

In Cakehp 3.7, use getSession() instead.

$this->request->getSession()->read('admin_logged_in');
