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

我对这个框架还很陌生，它对我来说太神奇了。
我甚至找不到它在route和controller中调用reset（）函数的位置。
但我知道在浏览了一整天的谷歌之后，在controller面前打过电话。
问题是，
我一直在测试用passwordbroker中的默认值覆盖函数reset和函数validatePasswordWithDefaults
我是通过扩展passwordbroker来实现的，但似乎我必须将illuminate\auth\passwords\passwordbroker中的所有函数完全迁移到
app\services\passwordbroker否则我将遇到错误：

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

我的示例代码如下：
自定义PasswordServiceProviders，用于绑定PasswordBroker以照亮PasswordBroker：

<?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;
        }
    }
    ?>

最佳答案

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，并提供一种从控制器重写它的方法。
我必须重写电子邮件发送，因为我需要使用mandrill的api，所以我必须在邮件发送的瞬间发送额外的邮件头。我就是这么做的：
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），但我必须对注册顺序和稍后检索令牌服务的方式做一些细微的修改。此外，您还必须指定passwordbroker的位置（在我的示例中是在\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'];
}

}
创建类\app\services\passwordbroker，在那里您可以重写emailresetlink（），这一步没有什么秘密。
从config\app.php（app\providers\passwordresetserviceprovider）在providers数组中注册新的提供程序。注释掉默认值（illumed\auth\passwords\passwordresetserviceprovider）
