### 安裝擴展庫
composer require lindelius/php-jwt
### 添加中間件 就叫 Jwt.php 吧 代碼大致如下
~~~
<?php
declare(strict_types=1);
namespace App\Middleware;
use Hyperf\HttpServer\Contract\RequestInterface;
use Hyperf\HttpServer\Contract\ResponseInterface as HttpResponse;
use Hyperf\Utils\Context;
use Lindelius\JWT\StandardJWT;
use Psr\Container\ContainerInterface;
use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\MiddlewareInterface;
use Psr\Http\Server\RequestHandlerInterface;
class Jwt implements MiddlewareInterface
{
/**
* @var ContainerInterface
*/
protected $container;
protected $response;
protected $request;
public function __construct(ContainerInterface $container, HttpResponse $response, RequestInterface $request)
{
$this->container = $container;
$this->response = $response;
$this->request = $request;
}
public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface
{
$headers = $request->getHeaders();
if (empty($headers['token'])) {
return $this->response->json(
[
'code' => 0,
'data' => [
'error' => 'token不能為空',
],
]
)->withStatus(401);
}
// 驗證token
$token = $headers['token'][0];
$jwt = new StandardJWT();
try {
$decodedJwt = $jwt::decode($token);
$payload = $decodedJwt->getPayload();
$userId = $payload['sub'];
$request = $request->withAttribute('userid', $userId);
// 添加屬性
Context::set(ServerRequestInterface::class, $request);
// 設置屬性
} catch (\Exception $exception) {
return $this->response->json(
[
'code' => $exception->getCode(),
'data' => [
'error' => $exception->getMessage()
],
]
)->withStatus(401);
}
return $handler->handle($request);
}
}
~~~
### 控制器中注入jwt中間件
~~~
<?php
namespace App\Controller;
use Hyperf\HttpServer\Annotation\AutoController;
use Hyperf\HttpServer\Annotation\Middleware;
use Lindelius\JWT\StandardJWT;
use App\Middleware\Jwt;
/**
* @AutoController()
* @Middleware(Jwt::class)
*/
class Home extends AbstractController
{
protected $userid;
public function index()
{
$arr = $this->request->getAttributes();
// 獲取屬性
return $arr['userid'];
}
}
~~~
