PHP

使用 Laravel 构建内容管理框架（六）

完成Entrust的配置

安装zizaco/entrust Package

zizaco/entrust是Laravel下基于角色的权限管理方案。

1.修改文件composer.json

"require": {
    "php": ">=5.5.9",
    "laravel/framework": "5.1.*",
    "gregwar/captcha": "1.*",
    "zizaco/entrust": "dev-laravel-5"
},

2.在终端运行命令

1
2
3
4
5
composer install
// or
composer update

3.在文件config/app.php的providers数组和aliase数组分别添加

1
2
3
4
5
// providers
Zizaco\Entrust\EntrustServiceProvider::class
// aliase
'Entrust' => Zizaco\Entrust\EntrustFacade::class,

4.在文件app/Http/Kernel.php的$routeMiddleware添加

1
2
3
'role' => Zizaco\Entrust\Middleware\EntrustRole::class,
'permission' => Zizaco\Entrust\Middleware\EntrustPermission::class,
'ability' => Zizaco\Entrust\Middleware\EntrustAbility::class,

5.Entrust会根据文件config/auth.php的model来选择用户模型，如下：

1
'model' => App\Models\User::class

执行以下命令生成配置文件config/entrust.php

1
php artisan vendor:publish

修改配置文件entrust.php如下:

1
2
'role'=>'App\Models\Role'
'permission'=>'App\Models\Permission'

6.生成数据库迁移文件并执行

1
2
php artisan entrust:migration
php artisan migrate

7.生成自动加载

1
composer dump-autoload

管理模型

为了使用Entrust，我们需要新建两个模型，在终端运行以下命令：

1
2
3
4
5
// 角色模型
php artisan make:model Models/Role
// 权限模型
php artisan make:model Models/Permission

Role.php

<?php
namespace App\Models;
use Zizaco\Entrust\EntrustRole;
class Role extends EntrustRole
{
    protected $guarded = [];
}

Permission.php

<?php
namespace App\Models;
use Zizaco\Entrust\EntrustPermission;
class Permission extends EntrustPermission
{
    protected $guarded = [];
}

为了配合Entrust的使用，需要修改User.php的代码

<?php
namespace App\Models;
use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Auth\Passwords\CanResetPassword;
use Illuminate\Foundation\Auth\Access\Authorizable;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;
use Zizaco\Entrust\Traits\EntrustUserTrait;
class User extends Model implements AuthenticatableContract,
    AuthorizableContract,
    CanResetPasswordContract
{
    use Authenticatable, Authorizable, CanResetPassword, EntrustUserTrait{
        Authorizable::can insteadof  EntrustUserTrait;
        EntrustUserTrait::can as hasPermission;
    }
    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ['name', 'email', 'password'];
    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = ['password', 'remember_token'];
}

完成上述所有操作之后，Entrust的配置就完成了。
