我有两张桌子:

人:

id   name   email   phone   person_type_id

用户

id   person_id  password role_id etc...

您能否告诉我如何让 Laravel(5.8)内置的身份验证系统在验证用户身份时使用person表中的电子邮件字段?仅供参考,守卫提供者的价值必须是用户

您可以创建一个自定义用户提供程序(继承自Illuminate\Auth\EloquentUserProvider)并覆盖该retrieveByCredentials方法。

请参阅Laravel 文档 - 用户提供者合约

@Thomas 的建议帮助我解决了这个问题。如果它可以帮助任何人,这是我的代码:

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();
 }   

}

然后在 App\Providers\AuthServiceProvider.php 文件中,在启动函数中:

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

在 config/auth.php 里面

 '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)

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');
}
