将额外数据传递给 finder auth

Question

我来自Auth 的查找器具有我需要访问$this->request 的条件，但我无法访问UsersTable。

AppController::初始化

$this->loadComponent('Auth', [
        'authenticate' => [
            'Form' => [
                'finder' => 'auth',
            ]
        ]
    ]);

用户表

public function findAuth(Query $query, array $options)
{
    $query
        ->select([
            'Users.id',
            'Users.name',
            'Users.username',
            'Users.password',
        ])
        ->where(['Users.is_active' => true]); // If I had access to extra data passed I would use here.

    return $query;
}

我需要将额外数据从AppController 传递到finder auth，因为我无法访问UsersTable 上的$this->request->data。

更新

人们在 cmets 上说这是一个糟糕的设计，所以我将准确解释我需要什么。

我有一个表users，但每个用户都属于一个gym。 username(email) 仅对特定的gym 是唯一的，因此我可以从gym_id 1 获得一个example@domain.com，从gym_id 2 获得另一个example@domain.com。 在登录页面我有gym_slug 告诉auth finder 我提供的用户gym 属于哪个username。

Answer 1

据我所知，没有办法通过将其传递到 3.1 中的配置来做到这一点。这可能是一个好主意，在 cakephp git hub 上作为功能请求提交。

有一些方法可以通过创建一个新的身份验证对象来扩展基本身份验证，然后覆盖 _findUser 和 _query。像这样的：

class GymFormAuthenticate extends BaseAuthenticate
{

 /**
  * Checks the fields to ensure they are supplied.
  *
  * @param \Cake\Network\Request $request The request that contains login information.
  * @param array $fields The fields to be checked.
  * @return bool False if the fields have not been supplied. True if they exist.
  */
 protected function _checkFields(Request $request, array $fields)
 {
     foreach ([$fields['username'], $fields['password'], $fields['gym']] as $field) {
         $value = $request->data($field);
         if (empty($value) || !is_string($value)) {
             return false;
         }
     }
     return true;
 }

 /**
  * Authenticates the identity contained in a request. Will use the `config.userModel`, and `config.fields`
  * to find POST data that is used to find a matching record in the `config.userModel`. Will return false if
  * there is no post data, either username or password is missing, or if the scope conditions have not been met.
  *
  * @param \Cake\Network\Request $request The request that contains login information.
  * @param \Cake\Network\Response $response Unused response object.
  * @return mixed False on login failure.  An array of User data on success.
  */
 public function authenticate(Request $request, Response $response)
 {
     $fields = $this->_config['fields'];
     if (!$this->_checkFields($request, $fields)) {
         return false;
     }
     return $this->_findUser(
         $request->data[$fields['username']],
         $request->data[$fields['password']],
         $request->data[$fields['gym']],
     );
 }

/**
  * Find a user record using the username,password,gym provided.
  *
  * Input passwords will be hashed even when a user doesn't exist. This
  * helps mitigate timing attacks that are attempting to find valid usernames.
  *
  * @param string $username The username/identifier.
  * @param string|null $password The password, if not provided password checking is skipped
  *   and result of find is returned.
  * @return bool|array Either false on failure, or an array of user data.
  */
 protected function _findUser($username, $password = null, $gym = null)
 {
     $result = $this->_query($username, $gym)->first();

     if (empty($result)) {
         return false;
     }

     if ($password !== null) {
         $hasher = $this->passwordHasher();
         $hashedPassword = $result->get($this->_config['fields']['password']);
         if (!$hasher->check($password, $hashedPassword)) {
             return false;
         }

         $this->_needsPasswordRehash = $hasher->needsRehash($hashedPassword);
         $result->unsetProperty($this->_config['fields']['password']);
     }

     return $result->toArray();
 }

/**
  * Get query object for fetching user from database.
  *
  * @param string $username The username/identifier.
  * @return \Cake\ORM\Query
  */
 protected function _query($username, $gym)
 {
     $config = $this->_config;
     $table = TableRegistryget($config['userModel']);

     $options = [
         'conditions' => [$table->aliasField($config['fields']['username']) => $username, 'gym' => $gym]
     ];

     if (!empty($config['scope'])) {
         $options['conditions'] = array_merge($options['conditions'], $config['scope']);
     }
     if (!empty($config['contain'])) {
         $options['contain'] = $config['contain'];
     }

     $query = $table->find($config['finder'], $options);

     return $query;
 }
 }

Answer 2

我知道这是一个老问题，但我想我会将我正在使用的查找器发布在我们基于 Cakephp 3 构建的 SaaS 应用程序之一中。它是否遵循 DRY 等可能不遵循。要说一切都可以通过 X 或 Y 方式完成......你总是不得不改变规则。在这种情况下，取决于 URL（xdomain.com 或 ydomain.com），我们的应用程序会确定客户是谁并更改布局等。此外，基于用户的用户与电子邮件和 site_id 非常相似

public function findAuth(\Cake\ORM\Query $query, array $options) {
    $query
            ->select([
                'Users.id',
                'Users.email',
                'Users.password',
                'Users.site_id',
                'Users.firstname',
                'Users.lastname'])
            ->where([
                'Users.active' => 1,
                'Users.site_id'=> \Cake\Core\Configure::read('site_id')
            ]);

    return $query;
}
