是否可以在Laravel中将数据传递给app.js？

Question

Is it possible to pass data to app.js in Laravel? I need to pass the value of Session::getId() to app.js since I create a websocket in that file. I know it is possible to get the CSRF-TOKEN like so:

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

but I need the session ID.

Thanks for any help!

Answer 1

The mentioned CSRF token works because you have a meta tag in your layout.

<meta name="csrf-token" content="{{ csrf_token() }}">

Not sure of the security implications of exposing the session id, but you could theoretically do the same.

<meta name="session-id" content="{{ session()->getId() }}">

$('meta[name="session-id"]').attr('content');

Answer 2

You can get it from cookie. The cookie name of session id in Laravel it is laravel_session.

    function getCookie(name) {

        var matches = document.cookie.match(new RegExp(
          "(?:^|; )" + name.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g, '\\$1') + "=([^;]*)"
))
return matches ? decodeURIComponent(matches[1]) : undefined
 }
var session_id = getCookie('laravel_session');
