在 laravel 中仅使用用户名（id）进行身份验证

Question

我正在创建一个 Laravel 项目，我想在其中添加仅基于用户名或 ID 的身份验证。关键是您可以将客户端连接到具有特定 ID 的设备。

目标：我进入页面，输入我持有的产品的 ID，然后设备登录产品帐户。

我尝试删除 make:auth 文件中的所有密码字段，现在我可以在没有密码的情况下注册，但是当我尝试登录我创建的帐户时，它只会停留在页面上。它不需要超级安全。

有人知道我需要更改什么文件/功能才能正常工作吗？

尝试@Option 提供的解决方案后，我收到以下错误：

Class Illuminate\Foundation\Auth\User contains 3 abstract method and
must therefore be declared abstract or implement the remaining methods
(Illuminate\Contracts\Auth\Authenticatable::getAuthPassword)

这是发生错误的文件：

    namespace Illuminate\Foundation\Auth;

    use Illuminate\Auth\Authenticatable;
    use Illuminate\Database\Eloquent\Model;
    use Illuminate\Auth\Passwords\CanResetPassword;
    use Illuminate\Foundation\Auth\Access\Authorizable;
    use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;
    use Illuminate\Contracts\Auth\Access\Authorizable as AuthorizableContract;
    use Illuminate\Contracts\Auth\CanResetPassword as CanResetPasswordContract;

    class User extends Model implements
        AuthenticatableContract,
        AuthorizableContract,
        CanResetPasswordContract
    {
        use Authenticatable, Authorizable;
    }

在您的登录控制器中试试这个。您需要覆盖 auth:make 凭据功能以根据需要进行自定义。

    namespace App\Http\Controllers\Auth;

    use Illuminate\Http\Request;
    use App\Http\Controllers\Controller;
    use Illuminate\Foundation\Auth\AuthenticatesUsers;

    class LoginController extends Controller
    {
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    protected function validateLogin(Request $request)
    {
        $this->validate($request, [
            $this->username() => 'required|string',
        ]);
    }

    protected function credentials(Request $request)
    {
        return array_merge($request->only($this->username()));
    }

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }
    }

我建议你通过隐藏输入字段来更改密码输入文本字段

<input type='hidden' name='password' value='0'>

然后编辑用户表的迁移，使用 bcrypt() 使密码自动输入 0

$table->string('password')->default(bcrypt(0));
