How to send JWT token to jQuery in Laravel

Question

When user presses the login button, I redirect to usercontroller.php and obtain jwt token from API.

$result = $this->obtainAccessToken($request->email, $request->password);

then I put the JWT token and user info to session.

Session::put('user', $result);

then redirect user to home page.

return redirect(route('home'));

Everything is ok.

I can access that token and user info in view (blade) pages using

Session::get('user');

But sometimes I need to request jQuery ajax to server. But I dont have token info in my js files. How can I send that token info which is stored in session to js files?

Also I tried to store that info in Cookie like;

Cookie::queue('user', $result, 10);

But I couldn't access in jQuery using;

$.Cookie('user');

it returns undefined.

UPDATE

I found a way something like this;

<meta name="token" content="{{ Session::get('user')->token }} />

and access using jQuery

$('meta[name=token]').attr('content);

but is it safe method?

I don't know what a JWT token is. If it must not be publicly displayed, then there is no safe way to pass it to any AJAX call. Otherwise it's good :) — user8555937

A jwt token is a common json web token which is send with a request. There exists a package called "jwt-auth". — Niklas

Yes, it is. It's the common way you would also choose if you do a ajax-request on your api.

The only thing that could happen is, that the api returns an error code 219 (session expired), when the token is false.
