Jwt 令牌解碼 - Symfony 4

Question

我正在嘗試解決與令牌請求相關的問題。 這是我在控制器中的 newArticle 函數（添加新文章）：

public function newArticle(Request $request, EntityManagerInterface $entityManager): View
    {
        $data = json_decode($request->getContent(), true);
        $title = $data['title'];
        $content = $data['content'];
        //$published_at = $data['published_at'];
        $authorizationHeader = $request->headers->get('Authorization');
        list(,$token) = explode(' ', $authorizationHeader);
        $jwtToken = $this->JWTEncoder->decode($token);
        $user_id = $data[$jwtToken];
        $userId = $this->userRepository->findOneBy(['id' => $user_id['id']]);
        $article = new Article();
        $article->setTitle($title);
        $article->setContent($content);
        $article->setPublishedAt(new \DateTime());
        $article->setUser($userId);
        // Todo: 400 response - Invalid input
        // Todo: 404 response - Response not found
        // Incase our Post was a success we need to return a 201 HTTP CREATED response with the created object
        if(in_array('ROLE_USER', $article->getUser()->getRoles(), true)) {
            $entityManager->persist($article);
            $entityManager->flush();
            return View::create("You added an article successfully!", Response::HTTP_OK);
        } else {
            return View::create(["You are not a user! So please register to add an article!"], Response::HTTP_BAD_REQUEST);
        }
    } 

在添加令牌標頭授權之前它正在工作，現在我收到此錯誤：

"error": {
   "code": 500,
  "message": "Internal Server Error",
 "message": "Notice: Undefined offset: 1", 

有人可以給我任何建議嗎？

Answer 1

我認為你的問題是這一行：

$user_id = $data[$jwtToken];

你應該重構它，認為它應該是這樣的：

$user_id = $data['user_id'];

或者

$user_id = $jwtToken['user_id'];

根據包含每個對象/數組的數據是您應該查找的位置。 首先，錯誤是為了調用數組上的偏移量，因此修復它應該沒問題（或者從日志中獲得更清晰的錯誤消息）
