如标题所示，是否可以在没有 DB 的情况下进行身份验证(而是使用 User Provider)？
我看过关于如何在没有密码的情况下进行身份验证的帖子，但是是否可以在没有DB的情况下进行身份验证？
这是我一直在努力实现的...
- 要求用户提交 PIN
- 将 PIN 与 .env 中的值进行比较
- 如果 PIN 正确，则对用户进行身份验证
introducing a user provider. 似乎可以在没有传统 RDBMS 的情况下进行身份验证
但是，该文档似乎没有描述用户提供者应该是什么样子。
这是我的代码片段(好吧，我只是模仿了文档)...
class AuthServiceProvider extends ServiceProvider {
public function boot()
{
$this->registerPolicies();
Auth::provider('myUser', function ($app, array $config) {
// Return an instance of Illuminate\Contracts\Auth\UserProvider...
return new MyUserProvider($app->make('myUser'));
});
}
}
在auth.php...
'providers' => [
'users' => [
'driver' => 'myUser',
],
],
现在，我不知道如何继续。
所以，我想知道...
用户提供者应该是什么样子如果可以首先使用
env()对用户进行身份验证
任何建议将不胜感激。
最佳答案
创建您自己的 Guard 忽略 UserProvider 接口(interface)。我在我的项目中采用了它并且运行良好。
PinGuard.php
<?php
declare(strict_types=1);
namespace App\Auth\Guards;
use App\User;
use Illuminate\Auth\AuthenticationException;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Http\Request;
/**
* Class PinGuard
*/
class PinGuard implements Guard
{
/**
* @var null|Authenticatable|User
*/
protected $user;
/**
* @var Request
*/
protected $request;
/**
* OpenAPIGuard constructor.
*
* @param Request $request
*/
public function __construct(Request $request)
{
$this->request = $request;
}
/**
* Check whether user is logged in.
*
* @return bool
*/
public function check(): bool
{
return (bool)$this->user();
}
/**
* Check whether user is not logged in.
*
* @return bool
*/
public function guest(): bool
{
return !$this->check();
}
/**
* Return user id or null.
*
* @return null|int
*/
public function id(): ?int
{
$user = $this->user();
return $user->id ?? null;
}
/**
* Manually set user as logged in.
*
* @param null|\App\User|\Illuminate\Contracts\Auth\Authenticatable $user
* @return $this
*/
public function setUser(?Authenticatable $user): self
{
$this->user = $user;
return $this;
}
/**
* @param array $credentials
* @return bool
*/
public function validate(array $credentials = []): bool
{
throw new \BadMethodCallException('Unexpected method call');
}
/**
* Return user or throw AuthenticationException.
*
* @throws AuthenticationException
* @return \App\User
*/
public function authenticate(): User
{
$user = $this->user();
if ($user instanceof User) {
return $user;
}
throw new AuthenticationException();
}
/**
* Return cached user or newly authenticate user.
*
* @return null|\App\User|\Illuminate\Contracts\Auth\Authenticatable
*/
public function user(): ?User
{
return $this->user ?: $this->signInWithPin();
}
/**
* Sign in using requested PIN.
*
* @return null|User
*/
protected function signInWithPin(): ?User
{
// Implement your logic here
// Return User on success, or return null on failure
}
/**
* Logout user.
*/
public function logout(): void
{
if ($this->user) {
$this->setUser(null);
}
}
}
NoRememberTokenAuthenticatable.php
用户应该混合这个特征。
<?php
declare(strict_types=1);
namespace App\Auth;
use Illuminate\Database\Eloquent\Model;
/**
* Trait NoRememberTokenAuthenticatable
*
* @mixin Model
*/
trait NoRememberTokenAuthenticatable
{
/**
* Get the name of the unique identifier for the user.
*
* @return string
*/
public function getAuthIdentifierName()
{
return 'id';
}
/**
* Get the unique identifier for the user.
*
* @return mixed
*/
public function getAuthIdentifier()
{
return $this->id;
}
/**
* Get the password for the user.
*
* @return string
* @codeCoverageIgnore
*/
public function getAuthPassword()
{
throw new \BadMethodCallException('Unexpected method call');
}
/**
* Get the token value for the "remember me" session.
*
* @return string
* @codeCoverageIgnore
*/
public function getRememberToken()
{
throw new \BadMethodCallException('Unexpected method call');
}
/**
* Set the token value for the "remember me" session.
*
* @param string $value
* @codeCoverageIgnore
*/
public function setRememberToken($value)
{
throw new \BadMethodCallException('Unexpected method call');
}
/**
* Get the column name for the "remember me" token.
*
* @return string
* @codeCoverageIgnore
*/
public function getRememberTokenName()
{
throw new \BadMethodCallException('Unexpected method call');
}
}
AuthServiceProvider.php
<?php
declare(strict_types=1);
namespace App\Providers;
use App\Auth\Guards\PinGuard;
use Illuminate\Container\Container;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;
use Illuminate\Support\Facades\Auth;
class AuthServiceProvider extends ServiceProvider
{
/**
* The policy mappings for the application.
*
* @var array
*/
protected $policies = [];
/**
* Register any authentication / authorization services.
*/
public function boot()
{
Auth::extend('pin', function (Container $app) {
return new PinGuard($app['request']);
});
$this->registerPolicies();
}
}
config/auth.php
你应该注释掉其中的大部分。
