如何在 Laravel 5.8 中扩展或制作自定义 PasswordBroker sendResetLink() 方法？

Question

目前重置密码背后的逻辑是用户必须提供 valid/registered 电子邮件才能接收密码恢复电子邮件。

在我的例子中，出于安全考虑，我不想验证电子邮件是否已注册，我只想在后端进行检查并告诉用户 "If he has provided registered e-mail, he should get recovery e-mail shortly"。

我为实现这一目标所做的工作是在 vendor\laravel\framework\src\Illuminate\Auth\Passwords\PasswordBroker.php sendResetLink() 方法中编辑的：

 /**
     * 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好的解决方案，因为它会在更新后消失。所以我想知道如何在 [=15] 的项目范围内扩展或实施此更改=] 文件夹 以始终保留此更改？

P.S。我已经尝试过这里提到的解决方案： 但它没有用.. 目录树也不同，我无法理解在哪里放置新的 PasswordBroker.php 文件。

提前致谢！

Answer 1

以下是您需要遵循的步骤。

创建新自定义 PasswordResetsServiceProvider。我有一个名为 Extensions 的文件夹（命名空间），我将在其中放置此文件：

<?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 registerPasswordBroker 方法返回自定义 PasswordBrokerManager。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，此 PasswordBrokerManager 扩展了 laravel 的基本管理器。这里唯一的区别是新的 resolve 方法，它 returns 来自同一命名空间的新自定义 PasswordBroker。所以我们将在同一命名空间中创建一个自定义 PasswordBroker 的最后一个文件：

<?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;
    }
}

如您所见，我们从 Laravel 扩展了默认的 PasswordBroker class 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替换 Laravel 默认 PasswordReset 代理。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。希望对您有所帮助。

此处最简单的解决方案是将自定义代码放入 app\Http\Controllers\Auth\ForgotPasswordController - 这是引入 SendsPasswordResetEmails 特征的控制器。

您的方法覆盖了该特征提供的方法，因此将调用它而不是特征中的方法。您可以使用您的代码覆盖整个 sendResetLinkEmail 方法，无论是否成功，始终 return 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.");
}

Answer 3

您可以只覆盖 ForgetPasswordController class 中的 sendResetLinkFailedResponse 方法。

protected function sendResetLinkFailedResponse(Request $request, $response)
{
    return $this->sendResetLinkResponse($request, Password::RESET_LINK_SENT);
}

即使验证失败，我们也会发送成功响应。
