How to retrieve or authorize a User object from a Laravel Bearer API token

UserFromBearerToken.php

<?php
use \League\OAuth2\Server\ResourceServer;
use \Laravel\Passport\TokenRepository;
use \Laravel\Passport\Guards\TokenGuard;
use \Laravel\Passport\ClientRepository;
use \Illuminate\Support\Facades\Auth;
use \Illuminate\Http\Request;

function getUser($bearerToken) {
  $tokenguard = new TokenGuard(
    App::make(ResourceServer::class), 
    Auth::createUserProvider('users'), 
    App::make(TokenRepository::class), 
    App::make(ClientRepository::class), 
    App::make('encrypter')
  );
  $request = Request::create('/');
  $request->headers->set('Authorization', 'Bearer ' . $bearerToken);
  return $tokenguard->user($request);
}

function authorizeUser($bearerToken) {
  $request = request();
  $request->headers->set('Authorization', 'Bearer ' . $bearerToken);
  Auth::setRequest($request);

  return Auth::user();
}

$token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsImp0aSI6IjI0NTU0MWVjNDE0NDk5YWRkO.......';

// to get the user associated with a bearer token:
$user = getUser($token);

// to log in a user given a bearer token:
// (you should have an already working Laravel Passport setup with Bearer token auth for this,
//  and please only use this in 'weird' scenarios where the default setup doesn't work and you 
//  have obtained the Bearer token through some other, external means)
authorizeUser($token);

There's no documentation whatsoever on how to get the User object from a Bearer token, or how to authorize a user given a Bearer token. It took me half a day to put this together, so I thought I'd share the result to save someone else the trouble.

It helped me! Thanks a lot!!!

Here's another approach instead of creating a request. https://vrajroham.me/find-user-from-accesstoken/

TypeError: Argument 2 passed to Laravel\Passport\Guards\TokenGuard::__construct() must be an instance of Laravel\Passport\PassportUserProvider

TypeError: Argument 2 passed to Laravel\Passport\Guards\TokenGuard::__construct() must be an instance of Laravel\Passport\PassportUserProvider

The fix for this, at least in Laravel 7 is to change the TokenGuard parameters to this:

      $tokenguard = new TokenGuard(
        App::make(ResourceServer::class), 
        new PassportUserProvider(Auth::createUserProvider('users'), 'users'), 
        App::make(TokenRepository::class), 
        App::make(ClientRepository::class), 
        App::make('encrypter')
      );

One thing to note is that 'users' being passed in the new PassportUserProvider line should be whatever you have set in config/auth.php as the provider in the Authentication Guards section

time saved
