前提

通常、laravel/passportをinstallして各種設定をしたら、以下のようなrouteが生成される。

# php artisan route:list
|        | POST      | oauth/authorize                         |                 | Laravel\Passport\Http\Controllers\ApproveAuthorizationController@approve  | Barryvdh\Cors\HandleCors::class,web,auth |
|        | GET|HEAD  | oauth/authorize                         |                 | Laravel\Passport\Http\Controllers\AuthorizationController@authorize       | Barryvdh\Cors\HandleCors::class,web,auth |
|        | DELETE    | oauth/authorize                         |                 | Laravel\Passport\Http\Controllers\DenyAuthorizationController@deny        | Barryvdh\Cors\HandleCors::class,web,auth |
|        | POST      | oauth/clients                           |                 | Laravel\Passport\Http\Controllers\ClientController@store                  | Barryvdh\Cors\HandleCors::class,web,auth |
|        | GET|HEAD  | oauth/clients                           |                 | Laravel\Passport\Http\Controllers\ClientController@forUser                | Barryvdh\Cors\HandleCors::class,web,auth |
|        | DELETE    | oauth/clients/{client_id}               |                 | Laravel\Passport\Http\Controllers\ClientController@destroy                | Barryvdh\Cors\HandleCors::class,web,auth |
|        | PUT       | oauth/clients/{client_id}               |                 | Laravel\Passport\Http\Controllers\ClientController@update                 | Barryvdh\Cors\HandleCors::class,web,auth |
|        | GET|HEAD  | oauth/personal-access-tokens            |                 | Laravel\Passport\Http\Controllers\PersonalAccessTokenController@forUser   | Barryvdh\Cors\HandleCors::class,web,auth |
|        | POST      | oauth/personal-access-tokens            |                 | Laravel\Passport\Http\Controllers\PersonalAccessTokenController@store     | Barryvdh\Cors\HandleCors::class,web,auth |
|        | DELETE    | oauth/personal-access-tokens/{token_id} |                 | Laravel\Passport\Http\Controllers\PersonalAccessTokenController@destroy   | Barryvdh\Cors\HandleCors::class,web,auth |
|        | GET|HEAD  | oauth/scopes                            |                 | Laravel\Passport\Http\Controllers\ScopeController@all                     | Barryvdh\Cors\HandleCors::class,web,auth |
|        | POST      | oauth/token                             |                 | Laravel\Passport\Http\Controllers\AccessTokenController@issueToken        | Barryvdh\Cors\HandleCors::class,throttle |
|        | POST      | oauth/token/refresh                     |                 | Laravel\Passport\Http\Controllers\TransientTokenController@refresh        | Barryvdh\Cors\HandleCors::class,web,auth |
|        | GET|HEAD  | oauth/tokens                            |                 | Laravel\Passport\Http\Controllers\AuthorizedAccessTokenController@forUser | Barryvdh\Cors\HandleCors::class,web,auth |
|        | DELETE    | oauth/tokens/{token_id}                 |                 | Laravel\Passport\Http\Controllers\AuthorizedAccessTokenController@destroy | Barryvdh\Cors\HandleCors::class,web,auth |

oauth/ というrouteがいくつか生成されている。
laravelでは通常、apiは api/ というrouteになるため、こちらのrouteに関してもapi/ にしたい。

手順

app_name/app/Providers/AuthServiceProvider.php の boot() を変更する。

デフォルトは以下のようになっている。

<?php

namespace App\Providers;

use Laravel\Passport\Passport;
use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
    ];

    /**
     * Register any authentication / authorization services.
     *
     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        Passport::routes();
    }
}

このファイルの

    public function boot()
    {
        $this->registerPolicies();

        Passport::routes();
    }

を

    public function boot()
    {
        $this->registerPolicies();
        $callback = null;
        $options = [
            'prefix' => 'api/oauth',
            'namespace' => '\Laravel\Passport\Http\Controllers',
        ];
        Passport::routes($callback, $options);
    }

にする。

これで、routeのprefixが oauth/ から　api/oauth に変更された。

php artisan route:list で確認するとこんな感じ。

# php artisan route:list
