Laravel 5.5 MDN Fetch API设置会话变量不起作用

Question

I'm using Laravel 5.5

I am trying to set session variable on GET fetch('/ajax-get-save-session') request.

Route::get('/ajax-get-save-session', function() { session(['my_key', 'Saved Session']) });

And when I try to access the session variable my_key in different route.

Route::get('/access-session', function() { return session('my_key'); });

NULL value is returned.

This routes are registered on Laravel web.php and I'm using MDN fetch API

Anyone?

Answer 1

If i understand your problem. You are looking for this. Try this:-

Use Session; //if your are using laravel 5.2 then add in top in routes. php or laravel 5.2 > greater versions in web.php 
// now put data in session
Route::get('/ajax-get-save-session', function() {
 Session::put('my_key','Saved Session');
});
//Access the session
Route::get('/access-session', function() { echo Session::get('my_key') });

Hope it helps!

It's totally my mistake. I never thought fetch() API is the one causing my problem. It says the description

By default, fetch won't send or receive any cookies from the server, resulting in unauthenticated requests if the site relies on maintaining a user session (to send cookies, the credentials init option must be set).

By doing :

fetch(url, { credentials : 'include' }).then(response => response.json())

SOLVED MY PROBLEM!
