Auth Bearer Tokens

The Auth implements a native bearer token implementation (JWT).

Generating a Token

When working with authentication via bearer tokens, the getBearerToken method can be used to obtain a bearer token (JWT) for the current user. It expires after 1 hour by default.

$token = Auth::getBearerToken();

You may also pass a user to this method to get a token for a specified user.

$token = Auth::getBearerToken($user);

When using the Session component, the token variable is available on this object.

{{ session.key}}

Verifying a Token

When verifying a token, use the checkBearerToken method that will return a valid user who is associated token, or false if the token is invalid or that user is no longer found.

$user = Auth::checkBearerToken($token);

The loginUsingBearerToken method is used to verify a supplied token and authenticate the user. The method returns the user if the verification was successful.

if ($jwtToken = Request::bearerToken()) {
    Auth::loginUsingBearerToken($jwtToken);
}

Note: Further configuration for this functionality can be found in the rainlab.user::config.bearer_token configuration value.

Working with APIs

When building API endpoints using CMS pages it can be useful to use a page for handling the authentication logic. The following is a simple example that includes various API endpoints.

title = "User API Page"
url = "/api/user/:action"

[resetPassword]
[account]
[session]
checkToken = 1
==
{% if this.param.action == 'signin' %}
    {% do response(
        ajaxHandler('onSignin').withVars({
            token: session.token()
        })
    ) %}
{% endif %}

{% if this.param.action == 'register' %}
    {% do response(ajaxHandler('onRegister')) %}
{% endif %}

{% if this.param.action == 'logout' %}
    {% do response(ajaxHandler('onLogout')) %}
{% endif %}

{% if this.param.action == 'refresh' %}
    {% do response({ data: {
        token: session.token()
    }}) %}
{% endif %}

An API layout to verify the user can be used for other API endpoints.

description = "Auth API Layout"
is_priority = 1

[session]
checkToken = 1
==
{% if session.user %}
    {% page %}
{% else %}
    {% do abort(403, 'Access Denied') %}
{% endif %}
