composer require lcobucci/jwt 3.3.3
composer require laravel/passport ~4.0
php artisan migrate
php artisan passport:install
运行完这个命令后，添加 Laravel\Passport\HasApiTokens trait 到 App\User 模型，该 trait 将会为模型类提供一些辅助函数用于检查认证用户的 token 和 scope：
<?php
namespace App;
use Laravel\Passport\HasApiTokens;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use HasApiTokens, Notifiable;
}
