Question

public function validateCredentials(UserContract $user, array $credentials)
    {
        $plain = $credentials['password'];

        return $this->hasher->check($plain, $user->getAuthPassword());
    }

如何覆盖类validateCredentials中的方法EloquentUserProvider？谢谢！

Answer 1

在Laravel 5.4中，您无需在 config / app.php 中注册 CustomUserProvider 。

首先，在 Providers 目录中创建 CustomUserProvider.php 文件：

<?php

namespace App\Providers;

use Illuminate\Auth\EloquentUserProvider as UserProvider;
use Illuminate\Contracts\Auth\Authenticatable as UserContract;


class CustomUserProvider extends UserProvider {

    public function validateCredentials(UserContract $user, array $credentials)
    {
        $plain = $credentials['password'];

        return $this->hasher->check($plain, $user->getAuthPassword());
    }

}

在此之后，更改 AuthServiceProvider.php 文件中的boot()方法：

public function boot()
{
    $this->registerPolicies();

    \Illuminate\Support\Facades\Auth::provider('customuserprovider', function($app, array $config) {
        return new CustomUserProvider($app['hash'], $config['model']);
    });
}

现在，您可以通过将驱动程序名称添加到 config / auth.php 文件来使用提供程序：

'providers' => [
    'users' => [
        'driver' => 'customuserprovider',
        'model' => App\User::class,
        'table' => 'users',
    ],
],

您可以创建自己的UserProvider，然后可以覆盖原始UserProvider中的功能。

首先创建CustomUserProvider：

use Illuminate\Contracts\Auth\UserProvider;
use Illuminate\Contracts\Auth\Authenticatable as UserContract;

class CustomUserProvider extends UserProvider {

  public function validateCredentials(UserContract $user, array $credentials)
  {
    $plain = $credentials['password'];

    return $this->hasher->check($plain, $user->getAuthPassword());
  }

}

然后在config / app.php

中注册新的CustomUserProvider

'providers' => array(
   ... On the bottom, must be down to override the default UserProvider
   'Your\Namespace\CustomUserProvider'
),
