CakePHP JWT Authenticate plugin

, _(*1)

Plugin containing AuthComponent's authenticate class for authenticating using JSON Web Tokens. You can read about JSON Web Token specification in detail here., _(*2)

Installation

composer require admad/cakephp-jwt-auth

Usage

Load the plugin using Cake's console:, _(*3)

./bin/cake plugin load ADmad/JwtAuth

Configuration:

Setup AuthComponent:, _(*4)

    // In your controller, for e.g. src/Api/AppController.php
    public function initialize(): void
    {
        parent::initialize();

        $this->loadComponent('Auth', [
            'storage' => 'Memory',
            'authenticate' => [
                'ADmad/JwtAuth.Jwt' => [
                    'userModel' => 'Users',
                    'fields' => [
                        'username' => 'id'
                    ],

                    'parameter' => 'token',

                    // Boolean indicating whether the "sub" claim of JWT payload
                    // should be used to query the Users model and get user info.
                    // If set to `false` JWT's payload is directly returned.
                    'queryDatasource' => true,
                ]
            ],

            'unauthorizedRedirect' => false,
            'checkAuthIn' => 'Controller.initialize',

            // If you don't have a login action in your application, set
            // 'loginAction' to empty string to prevent getting a MissingRouteException.
            'loginAction' => '',
        ]);
    }

Working

The authentication class checks for the token in two locations:, _(*5)

HTTP_AUTHORIZATION environment variable:, _(*6)

It first checks if token is passed using Authorization request header. The value should be of form Bearer <token>. The Authorization header name and token prefix Bearer can be customized using options header and prefix respectively., _(*7)
The query string variable specified using parameter config:, _(*8)

Next it checks if the token is present in query string. The default variable name is token and can be customzied by using the parameter config shown above., _(*9)

Known Issue

Some servers don't populate $_SERVER['HTTP_AUTHORIZATION'] when Authorization header is set. So it's up to you to ensure that either $_SERVER['HTTP_AUTHORIZATION'] or $_ENV['HTTP_AUTHORIZATION'] is set., _(*10)

For e.g. for apache you could use the following:, _(*11)

RewriteEngine On RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule .* - [e=HTTP_AUTHORIZATION:%1], _(*12)

or, _(*13)

SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1, _(*14)

Token Generation

You can use \Firebase\JWT\JWT::encode() of the firebase/php-jwt lib, which this plugin depends on, to generate tokens., _(*15)

The payload must have the "sub" (subject) claim whose value is used to query the Users model and find record matching the "id" field., _(*16)

Ideally you should also specify the token expiry time using exp claim., _(*17)

You can set the queryDatasource option to false to directly return the token's payload as user info without querying datasource for matching user record., _(*18)
