在測試Laravel應用程序時，一個加載門是如何定義的？

Question

我正在爲Laravel應用程序編寫測試。在我的AuthServiceProvider->boot()中，我根據數據庫中的權限表定義了許多用戶能力$gate->define()。

基本上這樣的：

foreach ($this->getPermissions() as $permission) { 
      $gate->define($permission->name, function ($user) use ($permission) { 
       return $user->hasPermission($permission->name); 
      }); 
     } 

在我的測試，我動態創建的權限，但AuthServiceProvider已經啓動了，這意味着我無法驗證與@can，Gate等用戶權限

有沒有適當的方法來處理這個問題？

Answer 1

你可以做這樣的事情裏面AuthServiceProvider

首先導入必要的軟件包

use Illuminate\Auth\Access\Gate; 
use Illuminate\Contracts\Auth\Access\Gate as GateContract; 
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider; 

，然後添加此boot()方法

public function boot(GateContract $gate) 
{ 
    parent::registerPolicies($gate); 

    $gate->define('update-post', function ($user, $post, $isModerator) { 
     // check if user id equals post user id or whatever 
     if ($user->id === $post->user->id) { 
      return true; 
     } 

     // you can define multiple ifs 
     if ($user->id === $category->user_id) { 
      return true; 
     } 

     if ($isModerator) { 
      return true; 
     } 

     return false; 
    }); 

    // you can also define multiple gates 
    $gate->define('update-sub', function($user, $subreddit) { 
     if($user->id === $subreddit->user->id) { 
      return true; 
     } 

     return false; 
    }); 

然後在你的控制器，你可以做些什麼像這樣

if (Gate::denies('update-post', [$post, $isModerator])) { 
    // do something 
} 

Answer 2

public function boot(GateContract $gate) 
{ 
    parent::registerPolicies($gate); 

    $gate->before(function($user, $ability) use ($gate){ 
     return $user->hasPermission($ability); 
    }); 
} 

我還沒有廣泛地測試過這個，但它似乎從我的快速測試工作。

Answer 3

我知道我對這場比賽有點晚了，但仍然 - 我自己也有同樣的問題，因此這個問題沒有一個全面的答案，這裏是我對同一問題的解決方案（在Laravel 5.3）：

我在我的app\Providers\AuthServiceProvider得到這個：

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

    if (!app()->runningInConsole()) { 
     $this->definePermissions($gate); 
    } 
} 

/** 
* @param Gate $gate 
*/ 
private function definePermissions(Gate $gate) 
{ 
    $permissions = Permission::with('roles')->get(); 

    foreach($permissions as $permission) { 
     $gate->define($permission->key, function($user) use ($permission) { 
      return $user->hasRole($permission->roles); 
     }); 
    } 
} 

這需要正常的應用程序流的照顧時不檢測和禁用過早政策登記時測試。

在我tests/TestCase.php文件我已經定義了以下方法（注意：Gate點Illuminate\Contracts\Auth\Access\Gate）：

/** 
* Logs a user in with specified permission(s). 
* 
* @param $permissions 
* @return mixed|null 
*/ 
public function loginWithPermission($permissions) 
{ 
    $user = $this->userWithPermissions($permissions); 

    $this->definePermissions(); 

    $this->actingAs($user); 

    return $user; 
} 

/** 
* Create user with permissions. 
* 
* @param $permissions 
* @param null $user 
* @return mixed|null 
*/ 
private function userWithPermissions($permissions, $user = null) 
{ 
    if(is_string($permissions)) { 
     $permission = factory(Permission::class)->create(['key'=>$permissions, 'label'=>ucwords(str_replace('_', ' ', $permissions))]); 

     if (!$user) { 
      $role = factory(Role::class)->create(['key'=>'role', 'label'=>'Site Role']); 

      $user = factory(User::class)->create(); 
      $user->assignRole($role); 
     } else { 
      $role = $user->roles->first(); 
     } 

     $role->givePermissionTo($permission); 
    } else { 
     foreach($permissions as $permission) { 
      $user = $this->userWithPermissions($permission, $user); 
     } 
    } 

    return $user; 
} 

/** 
* Registers defined permissions. 
*/ 
private function definePermissions() 
{ 
    $gate = $this->app->make(Gate::class); 
    $permissions = Permission::with('roles')->get(); 

    foreach($permissions as $permission) { 
     $gate->define($permission->key, function($user) use ($permission) { 
      return $user->hasRole($permission->roles); 
     }); 
    } 
} 

這使我在以多種方式測試使用此。考慮我的tests/integration/PermissionsTest.php文件中的用例：

/** @test */ 
public function resource_is_only_visible_for_those_with_view_permission() 
{ 
    $this->loginWithPermission('view_users'); 
    $this->visit(route('dashboard'))->seeLink('Users', route('users.index')); 
    $this->visit(route('users.index'))->assertResponseOk(); 

    $this->actingAs(factory(User::class)->create()); 
    $this->visit(route('dashboard'))->dontSeeLink('Users', route('users.index')); 
    $this->get(route('users.index'))->assertResponseStatus(403); 
} 

/** @test */ 
public function resource_action_is_only_visible_for_those_with_relevant_permissions() 
{ 
    $this->loginWithPermission(['view_users', 'edit_users']); 
    $this->visit(route('users.index'))->seeLink('Edit', route('users.edit', User::first()->id)); 

    $this->loginWithPermission('view_users'); 
    $this->visit(route('users.index'))->dontSeeLink('Edit', route('users.edit', User::first()->id)); 
} 

這在我所有的測試中都能正常工作。我希望它有幫助。
