掌握Laravel认证：解决Auth::user()为null的常见问题

// app/Models/Person.php

namespace App\Models;

use Illuminate\Contracts\Auth\Authenticatable; // 确保导入
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Notifications\Notifiable; // 可选，如果需要通知功能

// 继承 Illuminate\Foundation\Auth\User
// 或者手动实现 Authenticatable 接口
class Person extends Model implements Authenticatable
{
    use HasFactory, Notifiable; // 或其他需要的 traits

    protected $table = 'people'; // 如果表名不是 'users'

    /**
     * The attributes that are mass assignable.
     *
     * @var array<int, string>
     */
    protected $fillable = [
        'email',
        'password',
        // ... 其他字段
    ];

    /**
     * The attributes that should be hidden for serialization.
     *
     * @var array<int, string>
     */
    protected $hidden = [
        'password',
        'remember_token',
    ];

    // 实现 Authenticatable 接口所需的方法
    public function getAuthIdentifierName()
    {
        return 'id'; // 认证字段的名称，通常是 'id'
    }

    public function getAuthIdentifier()
    {
        return $this->getKey(); // 获取认证字段的值
    }

    public function getAuthPassword()
    {
        return $this->password; // 获取用户密码
    }

    public function getRememberToken()
    {
        return $this->remember_token; // 获取记住我令牌
    }

    public function setRememberToken($value)
    {
        $this->remember_token = $value; // 设置记住我令牌
    }

    public function getRememberTokenName()
    {
        return 'remember_token'; // 记住我令牌字段的名称
    }
}
