laravel5.2 session usage

Question

Excuse me, how to store, get the value and clear the session in laravel5.2.
I followed the documentation, but after storing it in controller A, I could not get the value in controller B.

Answer 1

// 存值
$request->session->put(key,value);

// 取值
$request->session->get(key);

// 清空
$request->session->flush()

Answer 2

The laravel file is really too rough. The session is probably a trap for many people. If it is not a normal return control layer function, you need to call session()->save()

Answer 3

There are two main points to pay attention to when using session add, delete, modify and check:
First, the session.php configuration is correct;
Second, the add, delete, modify, and check functions are not written incorrectly.
