Laravel5.5でPassportを使ったAuth認証を実装する方法

composer require laravel/passport

Laravel\Passport\PassportServiceProvider::class,

php artisan migrate

php artisan passport:install

<?php
namespace App;

{
 public function boot()
 {
  $this->registerPolicies();
  Passport::routes();
 }
}

Passport::routes(function(RouteRegistrar $router) {
 $router->forAccessTokens();
},['prefix' => 'api/oauth']);

 'web' => [
  'driver' => 'session',
  'provider' => 'users',

function respond($status, $respond)
{
 return response()->json(['status' => $status, is_string($respond) ? 'message' : 'data' => $respond]);
}
function succeed($respond = 'Request success!')
{
 return respond(true, $respond);
}
function failed($respond = 'Request failed!')
{
 return respond(false, $respond);
}
