Php Laravel身份验证-不同表中的电子邮件

我有两张桌子：

人员：

id   name   email   phone   person_type_id

使用者

您能告诉我如何使Laravel（5.8）的内置身份验证系统在对用户进行身份验证时使用persons表中的email字段吗？仅供参考，guard provider的值必须是users

您可以创建自定义用户提供程序（从

Lightning\Auth\EloquentUserProvider

继承）并覆盖

retrieveByCredentials

方法

托马斯的建议帮助我解决了这个问题。如果它对任何人都有帮助，以下是我的代码：

我创建了CustomUserProvider.php

<?php

namespace App\Providers;
use Illuminate\Support\Str;
use Illuminate\Auth\EloquentUserProvider;
use Illuminate\Contracts\Hashing\Hasher as HasherContract;

class CustomUserProvider extends EloquentUserProvider { 

private $method_to_email_model;

public function __construct(HasherContract $hasher, $model, $method_to_email_model)
{

    parent::__construct($hasher, $model);

    $this->method_to_email_model = $method_to_email_model;
}

public function retrieveByCredentials(array $credentials)
{

    if (empty($credentials) ||
       (count($credentials) === 1 &&
        array_key_exists('password', $credentials))) {
        return;
    }

    $query = $this->createModel()->newQuery();

    foreach ($credentials as $key => $value) 
    {
        if (Str::contains($key, 'password')) {
            continue;
        }

        if (is_array($value) || $value instanceof Arrayable) {

            $query->with([$this->method_to_email_model => function($q) use($key, $value){
                $q->whereIn($key, $value);
            }]);

        } else {


            $query->with([$this->method_to_email_model => function($q) use($key, $value){
                $q->where($key, $value);
            }]);
        }
    }

    return $query->first();
 }   

}

在config/auth.php内部

 'providers' => [ 
    'users' => [
        'driver'                => 'custom_user_provider',
        'model'                 => App\User::class,
        'method_to_email_model' => 'person',
    ],
  ],

最后在App\User.php（用户模型）中

您可以在auth-config文件中更改默认用户模型，但我仍然认为它不起作用，因为它要求电子邮件和密码在同一个模型中。唯一的另一种方法是创建自定义保护以覆盖Larvels默认值

Auth::provider('custom_user_provider', function ($app, array $config) {
    return new CustomUserProvider($app['hash'], $config['model'], $config['method_to_email_model']);
});

 'providers' => [ 
    'users' => [
        'driver'                => 'custom_user_provider',
        'model'                 => App\User::class,
        'method_to_email_model' => 'person',
    ],
  ],

protected $appends = [
    'email', 'first_name', 'last_name'
 ];

public function person()
{
    return $this->belongsTo(Person::class, 'person_id', 'id');
}

public function getEmailAttribute()
{
    return $this->person->getAttribute('email');
}

public function getFirstNameAttribute()
{
    return $this->person->getAttribute('first_name');
}

public function getLastNameAttribute()
{
    return $this->person->getAttribute('last_name');
}
