http-status-code-503 相关问题

我已经更新到 symfony 6.4，突然我无法保存任何带有新行或任何 html 代码（如）的文本区域的表单。当我写一行不换行时，表单会提交我已经更新到 symfony 6.4，突然我无法保存任何带有换行符的文本区域或任何 html 代码（如 <p>）的表单。当我写一行不换行时，表单提交成功。我收到 403 禁止错误有时，当我在不使用ajax（使用渲染和表单）的情况下提交表单时，第二次提交表单时会收到503错误，并且我必须删除缓存才能成功提交。但是，对于 403 错误，我无法做任何事情来用新行或任何 html 代码提交它。这是导致 403 的代码示例： #[Route(path: '/ajax/save/new', name: 'new_lesson_plan')] public function newLessonPlan( LessonPlanRepository $lessonPlanRepo, Request $request, SessionRepository $sessionRepo, Mailer $mailer, SendSms $sendSms, ShortenUrl $shortenUrl, Environment $twig ): Response { $new_stuff = $request->request->get('new_stuff'); $finger_exercises = $request->request->get('finger_exercises'); $previous_pieces = $request->request->get('previous_pieces'); $current_piece = $request->request->get('current_piece'); $techniques_reinforced = $request->request->get('techniques_reinforced'); $extend_to_learn = $request->request->get('extend_to_learn'); $print_out = $request->request->get('print_out'); $assignment_for_student = $request->request->get('assignment_for_student'); $modify = $request->request->get('modify'); $sess_id = $request->request->get('session_id'); $session = $sessionRepo->findOneById($sess_id); $activity_string = ""; $activity_string .= "<h3>Warm-up</h3>"; $activity_string .= "<p>" . nl2br($finger_exercises) . "</p>"; $activity_string .= "<h3>Repertoire</h3>"; $activity_string .= "<p>" . nl2br($previous_pieces) . "</p>"; $activity_string .= "<h3>Creative</h3>"; $activity_string .= "<p> Learn: " . nl2br($new_stuff) . "</p>"; $activity_string .= "<h3>Current piece: " . $current_piece . "</h3>"; $activity_string .= "<p> This piece will reinforce the following: ". $techniques_reinforced .". I intend to do " . $extend_to_learn . "</p>"; $activity_string .= "<h3>Print outs</h3>"; $activity_string .= "<p>" . $print_out . "</p>"; $activity_string .= "<h3>Assignment</h3>"; $activity_string .= "<p>" . nl2br($assignment_for_student) . "</p>"; if($modify == 'false') { $lessonPlan = new LessonPlan(); $lp = 'Lesson Plan'; } else { $lessonPlan = $lessonPlanRepo->findOneBySession($session); $lp = 'Assessed Lesson Plan'; } $lessonPlan->setAddedOn($session->getBeginAt()); $lessonPlan->setSession($session); $lessonPlan->setStudent($session->getStudent()); $lessonPlan->setAddedOn(new \Datetime()); $lessonPlan->setWork($new_stuff); $lessonPlan->setActivities($activity_string); $entityManager = $this->managerRegistry->getManager(); $entityManager->persist($lessonPlan); $entityManager->flush(); $student = $lessonPlan->getStudent(); $teacher = $session->getTeacher(); $html = $twig->render('pdf/student_lesson_plan.html.twig', [ 'session' => $session, 'lesson_plan' => $lessonPlan, ]); $uigName = explode("-", (string) $session->getUserInstrumentGrade())[0]; $urlShort = $shortenUrl...; $sendSms->quickSend...; $mailer->sendEmailWithAttachment(...); $this->addFlash( 'success', 'The lesson plan was sent successfully.' ); return new JsonResponse($sess_id); } 我已经粘贴了整个函数，因为我不知道是否有任何行导致了问题。这是表单的控制器： #[Route(path: '/new/for/{session_id}', name: 'lesson_plan_new', methods: ['GET', 'POST'])] public function new(Request $request, SessionRepository $sessionRepo, UserInstrumentGradeRepository $uigRepo, LessonPlanRepository $lessonPlanRepo, $session_id): Response { $this->denyAccessUnlessGranted('IS_AUTHENTICATED_REMEMBERED'); $session = $sessionRepo->findOneById($session_id); $lessonPlan = new LessonPlan(); $uig = $session->getUserInstrumentGrade(); $sessions = $uig->getSessions(); $lessonPlan->setAddedOn($session->getBeginAt()); $form = $this->createForm(LessonPlanType::class, $lessonPlan); $form->handleRequest($request); if ($form->isSubmitted() && $form->isValid()) { $lessonPlan->setSession($session); $lessonPlan->setStudent($session->getStudent()); $lessonPlan->setAddedOn(new \Datetime()); $entityManager = $this->managerRegistry->getManager(); $entityManager->persist($lessonPlan); $entityManager->flush(); return $this->redirectToRoute('lesson_plan_index', ['student_id' => $lessonPlan->getStudent()->getId()], Response::HTTP_SEE_OTHER); } $lessonPlanForThisSession = $lessonPlanRepo->findOneBySession($session); return $this->render('lesson_plan/new.html.twig', [ 'session' => $session, 'sessions' => $sessions, 'lessonPlanForThisSession' => $lessonPlanForThisSession, 'lesson_plan' => $lessonPlan, 'form' => $form, ]); } 碰巧 mod_security 是由我的托管公司激活的。根据 namecheap.com 上的信息，我们的共享服务器上 mod_security 规则触发的最常见错误是 403 Forbidden...有时，由于网站编码不佳，mod_security 可能会错误地确定某个请求是恶意的，虽然它实际上是合法的。当发生这种情况时，您仍然会收到 403 错误。让他们停用 mod_security 让我能够成功提交表单。我仍然不知道我在哪里做“糟糕的网站编码”，但这就是错误的原因。

对 /php_fpm_status 的许多请求和服务器无响应

服务器变得非常缓慢且无响应，我重新启动了 apache 和 nginx 几次。我查看了我的 Apache mod_status 页面，除了 100-200 个正常的请求之外，我还看到了 10-20 个对 /php_fpm_status 的请求
