Password reset in Laravel 5.5 by email or mobile

问题:

By default Laravel 5.5's password reset system works on email, but I need to add support for a mobile number (verify by OTP and generate a token and redirect to password reset page). I am doing all this part and I have created a mobile column on password_resets table.

But the problem is \Illuminate\Auth\Passwords\DatabaseTokenRepository && \Illuminate\Auth\Passwords\TokenRepositoryInterface ON exist method and it doesn't seem configurable.

public function exists(CanResetPasswordContract $user, $token)
{
    $record = (array) $this->getTable()->where(
        'email', $user->getEmailForPasswordReset()
    )->first();

    return $record &&
           ! $this->tokenExpired($record['created_at']) &&
             $this->hasher->check($token, $record['token']);
}

I need to override that method. There's so much inheritance going on. What classes do I need to extend and how to override that method.

If you want to override behaviour of \Illuminate\Auth\Passwords\DatabaseTokenRepository methods, you will have to override every method that references "email" column. Create these files:

/App/Auth/DatabaseTokenRepository.php

<?php

namespace App\Auth;

use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;
use Illuminate\Auth\Passwords\DatabaseTokenRepository as DatabaseTokenRepositoryBase;

class DatabaseTokenRepository extends DatabaseTokenRepositoryBase
{

    public function create(CanResetPasswordContract $user)
    {
        $email = $user->getEmailForPasswordReset();
        $mobile = $user->getMobileForPasswordReset();
        $this->deleteExisting($user);
        $token = $this->createNewToken();
        $this->getTable()->insert($this->getPayload($email, $mobile, $token));
        return $token;
    }

    protected function deleteExisting(CanResetPasswordContract $user)
    {
        return $this->getTable()
            ->where('email', $user->getEmailForPasswordReset())
            ->orWhere("mobile", $user->getMobileForPasswordReset())
            ->delete();
    }

    protected function getPayload($email, $mobile, $token)
    {
        return ['email' => $email, 'mobile' => $mobile, 'token' => $this->hasher->make($token), 'created_at' => new Carbon];
    }

    public function exists(CanResetPasswordContract $user, $token)
    {
        $record = (array) $this->getTable()
            ->where('email', $user->getEmailForPasswordReset())
            ->orWhere("mobile", $user->getMobileForPasswordReset())
            ->first();
        return $record &&
               ! $this->tokenExpired($record['created_at']) &&
                 $this->hasher->check($token, $record['token']);
    }
}

Now you will need to use this custom token repository instead of the default one. So you have to override another class.

/App/Auth/PasswordBrokerManager.php

<?php
namespace App\Auth;

use Illuminate\Support\Str;
use Illuminate\Auth\Passwords\PasswordBrokerManager as PasswordBrokerManagerBase;

class PasswordBrokerManager extends PasswordBrokerManagerBase
{

    protected function createTokenRepository(array $config)
    {
        $key = $this->app['config']['app.key'];
        if (Str::startsWith($key, 'base64:')) {
            $key = base64_decode(substr($key, 7));
        }
        $connection = $config['connection'] ?? null;
        return new DatabaseTokenRepository(
            $this->app['db']->connection($connection),
            $this->app['hash'],
            $config['table'],
            $key,
            $config['expire']
        );
    }
}

Now you have created a custom broker to use your custom repository. You need a new service provider to make use of it.

/App/Providers/PasswordResetServiceProvider.php

<?php
namespace App\Providers;

use App\Auth\PasswordBrokerManager;
use Illuminate\Auth\Passwords\PasswordResetServiceProvider as PasswordResetServiceProviderBase;

class PasswordResetServiceProvider extends PasswordResetServiceProviderBase
{
    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();
        });
    }
}

Then just replace default password reset service provider with the custom one in your application config.
