README

This package allows you to add claims to Laravel Passport JWT Tokens. If you have questions or comments, please open an issue.

Installation

This package only supports Laravel 11 and 12. You can try to use older versions of this package but it's not supported.

Via Composer

composer require corbosman/laravel-passport-claims

Usage

This package sends the AccessToken class through a pipeline of classes to collect all the claims, similar to how laravel middleware works. Each class adds a claim to the token. For each claim that you want to add, you need to create a class like the example below. You can of course add multiple claims in a single class as well.

You can use an artisan command to generate a class for you. Just provide a path from the root of your app folder. The example below will create a class app/Claims/CustomClaim.php

php artisan claim:generate Claims/CustomClaim

<?php
namespace App\Claims;
use CorBosman\Passport\AccessToken;  // extends Laravel\Passport\Bridge\AccessToken

class CustomClaim
{
    public function handle(AccessToken $token, $next)
    {
        $token->addClaim('my-claim', 'my custom claim data');

        return $next($token);
    }
}

Because the Passport AccessToken is sent through the pipeline, you have access to methods on the AccessToken class. This is useful if you want to derive information from the token. For instance, look up user data based on the token user identifier. You can check the AccessToken class to see all the methods you can use.

<?php

namespace App\Claims;

use App\User;
use CorBosman\Passport\AccessToken; // extends Laravel\Passport\Bridge\AccessToken

class CustomClaim
{
    public function handle(AccessToken $token, $next)
    {
        $user = User::find($token->getUserIdentifier());

        $token->addClaim('email', $user->email);

        return $next($token);
    }
}

config

To tell this package which claims you want to add, you need to publish the config file and add a list of all your classes. To publish the config file, run the following command after installing this package.

php artisan vendor:publish --provider="CorBosman\Passport\ServiceProvider"

The config file will look like this.

<?php

return [
    /*
    |--------------------------------------------------------------------------
    | JWT Claim Classes
    |--------------------------------------------------------------------------
    |
    | Here you can add an array of classes that will each be called to add
    | claims to the passport JWT token. See the readme for the interface that
    | these classes should adhere to.
    |
    */
    'claims' => [
        App\Claims\MyCustomClaim::class,
        App\Claims\MyOtherCustomClaim::class
    ]
];

middleware

You can set a middleware on a route that checks for the existence of a specific claim. Add the middleware to your \App\Http\Kernel.php class:

    protected $routeMiddleware = [
        'claim' => \CorBosman\Passport\Http\Middleware\CheckForClaim::class,
    ];

Then assign this middleware to a route. Generally you would also add a passport middleware that checks for a valid token.

Route::middleware(['client', 'claim:my-claim'])->get('my-protected-route', function () {
    return 'protected by claim';
});

You can check if the claim matches a specific value.

Route::middleware(['client', 'claim:my-claim,foobar'])->get('my-protected-route', function () {
    return 'protected by claim with foobar as its value';
});

You can also check if the claim matches a specific value from multiple values, you just need to add the values ​​separated with |.

Route::middleware(['client', 'claim:my-claim,foo|bar'])->get('my-protected-route', function () {
    return 'protected by claim with foo or bar as its value';
});

Formatters

This package also allows you to configure custom Formatters. Formatters can be used to modify existing claims. You could even use them to add claims. A common reason to opt for a custom Formatter is to change the DateTime fields in the JWT from floats back to integers. Due to a change in a library, JWTs are now issued with float values, which breaks compatibility with virtually all other JWT libraries. If you run into that problem, all you have to do is add the following to the passport-claims.php config file:

   'formatters' => [
        \Lcobucci\JWT\Encoding\UnifyAudience::class,
        \Lcobucci\JWT\Encoding\UnixTimestampDates::class,
    ]

This swaps out the microsecond formatter with the old unix timestamp formatter. You're of course also free to add any other custom claim formatters.
