php - 如何在 PasswordBroker Laravel 5 中覆盖 reset 和 validatePasswordWithDefaults

Question

我真的是这个框架的新手，它对我来说太神奇了。 我什至找不到它在路由和 Controller 中调用函数 reset() 的位置。 但我知道在浏览了一整天的谷歌之后，它已经在 Controller 之前被调用了。

问题来了 我一直在测试覆盖 PasswordBroker 中的函数重置和函数 validatePasswordWithDefaults

我通过扩展 PasswordBroker 来做到这一点，但似乎我必须将 Illuminate\Auth\Passwords\PasswordBroker 中的所有功能完全迁移到我的 App\Services\PasswordBroker 否则我会遇到错误:

Target [Illuminate\Contracts\Auth\UserProvider] is not instantiable

我的示例代码在这里:

将我的 PasswordBroker 绑定(bind)到 Illuminate PasswordBroker 的自定义 PasswordServiceProvider:

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class PasswordResetServiceProvider extends ServiceProvider {

/**
 * Bootstrap the application services.
 *
 * @return void
 */
public function boot()
{
    //
}

/**
 * Register the application services.
 *
 * @return void
 */
public function register()
{
    //
    $this->app->bind(
        'Illuminate\Contracts\Auth\PasswordBroker','App\Services\PasswordBroker'
        );


}

}

Custom PasswordBroker:
<?php
    namespace App\Services;


    use Illuminate\Contracts\Auth\UserProvider;
    use Illuminate\Auth\Passwords\TokenRepositoryInterface;
    use Illuminate\Auth\Passwords\PasswordBroker as BasePasswordBroker;
    use Illuminate\Contracts\Auth\PasswordBroker as ContractPasswordBroker;

    use Closure;

    class PasswordBroker extends BasePasswordBroker
    {

        public function reset(array $credentials, Closure $callback)
        {
            dd($callback);
            $user = $this->validateReset($credentials);

            if ( ! $user instanceof CanResetPasswordContract)
            {
                return $user;
            }

            $pass = $credentials['password'];

            call_user_func($callback, $user, $pass);

            $this->tokens->delete($credentials['token']);

            return PasswordBrokerContract::PASSWORD_RESET;
        }

        protected function validatePasswordWithDefaults(array $credentials)
        {
            list($password, $confirm) = [
                $credentials['password'], $credentials['password_confirmation'],
            ];

            return $password === $confirm && mb_strlen($password) >= 4;
        }
    }
    ?>

这并不简单，在我看来，框架不应该向代码发送如此深入的电子邮件，并提供一种从 Controller 覆盖它的方法。

我不得不覆盖电子邮件发送，因为我需要使用 Mandrill 的 api，所以我必须在邮件发送的那一刻发送额外的标题。这就是我所做的:

1. 在 App\Providers\PasswordResetServiceProvider 上创建提供程序类。我复制了框架的默认提供程序 (Illuminate\Auth\Passwords\PasswordResetServiceProvider)，但我不得不对注册顺序和稍后检索 token 服务的方式进行一些细微修改。您还必须指定您的 PasswordBroker 的位置(在我的例子中是在\App\Services\PasswordBroker 上)

    use Illuminate\Support\ServiceProvider;
    use Illuminate\Auth\Passwords\DatabaseTokenRepository as DbRepository;
   
    class PasswordResetServiceProvider extends ServiceProvider {
   
   /**
    * Indicates if loading of the provider is deferred.
    *
    * @var bool
    */
   protected $defer = true;
   
   /**
    * Register the service provider.
    *
    * @return void
    */
   public function register()
   {
       $this->registerTokenRepository();
       $this->registerPasswordBroker();
   }
   
   /**
    * Register the password broker instance.
    *
    * @return void
    */
   protected function registerPasswordBroker()
   {
       return $this->app->singleton('auth.password', function($app)
       {
           // The password token repository is responsible for storing the email addresses
           // and password reset tokens. It will be used to verify the tokens are valid
           // for the given e-mail addresses. We will resolve an implementation here.
           $tokens = $app['auth.password.tokens'];
   
           $users = $app['auth']->driver()->getProvider();
   
           $view = $app['config']['auth.password.email'];
   
           // The password broker uses a token repository to validate tokens and send user
           // password e-mails, as well as validating that password reset process as an
           // aggregate service of sorts providing a convenient interface for resets.
           return new \App\Services\PasswordBroker(
               $tokens, $users, $app['mailer'], $view
           );
       });
   }
   
   /**
    * Register the token repository implementation.
    *
    * @return void
    */
   protected function registerTokenRepository()
   {
       $this->app->singleton('auth.password.tokens', function($app)
       {
           $connection = $app['db']->connection();
   
           // The database token repository is an implementation of the token repository
           // interface, and is responsible for the actual storing of auth tokens and
           // their e-mail addresses. We will inject this table and hash key to it.
           $table = $app['config']['auth.password.table'];
   
           $key = $app['config']['app.key'];
   
           $expire = $app['config']->get('auth.password.expire', 60);
   
           return new DbRepository($connection, $table, $key, $expire);
       });
   }
   
   /**
    * Get the services provided by the provider.
    *
    * @return array
    */
   public function provides()
   {
       return ['auth.password', 'auth.password.tokens'];
   }
   

   1. 创建类\App\Services\PasswordBroker，在那里你可以覆盖 emailResetLink()，这一步没有什么神秘的。

   2. 在 config\app.php (App\Providers\PasswordResetServiceProvider) 的提供者数组中注册新的提供者。注释掉默认的(Illuminate\Auth\Passwords\PasswordResetServiceProvider)
