目前，重置密码的逻辑是用户必须提供有效/注册的电子邮件才能接收密码恢复电子邮件。
在我的情况下，由于安全问题，我不想验证电子邮件是否已注册，我想在后端进行检查，并告诉用户“如果他已提供注册的电子邮件，他应该很快得到恢复电子邮件“。
我在vendor\laravel\framework\src\Illuminate\Auth\Passwords\PasswordBroker.php sendResetLink()方法中编写的实现此目的的方法是：
/**
* Send a password reset link to a user.
*
* @param array $credentials
* @return string
*/
public function sendResetLink(array $credentials)
{
// First we will check to see if we found a user at the given credentials and
// if we did not we will redirect back to this current URI with a piece of
// "flash" data in the session to indicate to the developers the errors.
$user = $this->getUser($credentials);
if (is_null($user)) {
return static::INVALID_USER;
}
// Once we have the reset token, we are ready to send the message out to this
// user with a link to reset their password. We will then redirect back to
// the current URI having nothing set in the session to indicate errors.
$user->sendPasswordResetNotification(
$this->tokens->create($user)
);
return static::RESET_LINK_SENT;
}
对此：
/**
* Send a password reset link to a user.
*
* @param array $credentials
* @return string
*/
public function sendResetLink(array $credentials)
{
// First we will check to see if we found a user at the given credentials and
// if we did not we will redirect back to this current URI with a piece of
// "flash" data in the session to indicate to the developers the errors.
$user = $this->getUser($credentials);
// if (is_null($user)) {
// return static::INVALID_USER;
// }
// Once we have the reset token, we are ready to send the message out to this
// user with a link to reset their password. We will then redirect back to
// the current URI having nothing set in the session to indicate errors.
if(!is_null($user)) {
$user->sendPasswordResetNotification(
$this->tokens->create($user)
);
}
return static::RESET_LINK_SENT;
}
这个硬编码选项不是最佳解决方案，因为它会在更新后消失。所以我想知道如何在App文件夹中的项目范围内扩展或实现此更改以始终保留此更改？
附：我已经尝试过这里提到的解决方案：Laravel 5.3 Password Broker Customization但它没有工作..目录树也不同，我无法理解在哪里放新的PasswordBroker.php文件。
提前致谢！
这里最简单的解决方案是将您的自定义代码放在app\Http\Controllers\Auth\ForgotPasswordController中 - 这是控制器拉入SendsPasswordResetEmails特性。
您的方法会覆盖该特征提供的方法，因此将调用该方法而不是特征中的方法。您可以使用代码覆盖整个sendResetLinkEmail方法，无论成功与否，始终都会返回相同的响应。
public function sendResetLinkEmail(Request $request)
{
$this->validateEmail($request);
// We will send the password reset link to this user. Once we have attempted
// to send the link, we will examine the response then see the message we
// need to show to the user. Finally, we'll send out a proper response.
$response = $this->broker()->sendResetLink(
$request->only('email')
);
return back()->with('status', "If you've provided registered e-mail, you should get recovery e-mail shortly.");
}
以下是您需要遵循的步骤。
创建一个新的自定义PasswordResetsServiceProvider。我有一个名为Extensions的文件夹（命名空间），我将放置此文件：
<?php
namespace App\Extensions\Passwords;
use Illuminate\Auth\Passwords\PasswordResetServiceProvider as BasePasswordResetServiceProvider;
class PasswordResetServiceProvider extends BasePasswordResetServiceProvider
{
/**
* Indicates if loading of the provider is deferred.
*
* @var bool
*/
protected $defer = true;
/**
* Register the service provider.
*
* @return void
*/
public function register()
{
$this->registerPasswordBroker();
}
/**
* Register the password broker instance.
*
* @return void
*/
protected function registerPasswordBroker()
{
$this->app->singleton('auth.password', function ($app) {
return new PasswordBrokerManager($app);
});
$this->app->bind('auth.password.broker', function ($app) {
return $app->make('auth.password')->broker();
});
}
}
如您所见，此提供程序扩展了基本密码重置提供程序。唯一改变的是我们从PasswordBrokerManager方法返回自定义registerPasswordBroker。让我们在同一个命名空间中创建一个自定义Broker管理器：
<?php
namespace App\Extensions\Passwords;
use Illuminate\Auth\Passwords\PasswordBrokerManager as BasePasswordBrokerManager;
class PasswordBrokerManager extends BasePasswordBrokerManager
{
/**
* Resolve the given broker.
*
* @param string $name
* @return \Illuminate\Contracts\Auth\PasswordBroker
*
* @throws \InvalidArgumentException
*/
protected function resolve($name)
{
$config = $this->getConfig($name);
if (is_null($config)) {
throw new InvalidArgumentException(
"Password resetter [{$name}] is not defined."
);
}
// 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 PasswordBroker(
$this->createTokenRepository($config),
$this->app['auth']->createUserProvider($config['provider'] ?? null)
);
}
}
同样，这个PasswordBrokerManager从laravel扩展了基本管理器。这里唯一的区别是新的resolve方法，它从同一名称空间返回一个新的和自定义的PasswordBroker。所以最后一个文件我们将在同一名称空间中创建自定义PasswordBroker：
<?php
namespace App\Extensions\Passwords;
use Illuminate\Auth\Passwords\PasswordBroker as BasePasswordBroker;
class PasswordBroker extends BasePasswordBroker
{
/**
* Send a password reset link to a user.
*
* @param array $credentials
* @return string
*/
public function sendResetLink(array $credentials)
{
// First we will check to see if we found a user at the given credentials and
// if we did not we will redirect back to this current URI with a piece of
// "flash" data in the session to indicate to the developers the errors.
$user = $this->getUser($credentials);
// if (is_null($user)) {
// return static::INVALID_USER;
// }
// Once we have the reset token, we are ready to send the message out to this
// user with a link to reset their password. We will then redirect back to
// the current URI having nothing set in the session to indicate errors.
if(!is_null($user)) {
$user->sendPasswordResetNotification(
$this->tokens->create($user)
);
}
return static::RESET_LINK_SENT;
}
}
正如您所看到的，我们从Laravel扩展了默认的PasswordBroker类，并且只覆盖了我们需要覆盖的方法。
最后一步是简单地用我们的Laravel Default PasswordReset代理替换它。在config/app.php文件中，更改注册提供程序的行：
'providers' => [
...
// Illuminate\Auth\Passwords\PasswordResetServiceProvider::class,
App\Extensions\Passwords\PasswordResetServiceProvider::class,
...
]
这就是注册自定义密码代理所需的全部内容。希望有所帮助。
