URL restituisce 504 errore quando chiamato da HTTP

Question

ho questo codice, per attivare alcune chiamate asincrone http:

private CompleteRoutingResponseWrapper sendRoutingRequestString(int numOfTries, String routingRequestUrl) { 
    routingRequestUrl = urlUtils.getHttpUrl(routingRequestUrl); 

    CompleteRoutingResponseWrapper answer = new CompleteRoutingResponseWrapper(); 
    CloseableHttpClient client = HttpClientBuilder.create().build(); 
    CloseableHttpResponse response = null; 
    try { 

     Stopwatch stopWatch = Stopwatch.createStarted(); 
     response = client.execute(new HttpGet(routingRequestUrl)); 
     stopWatch.stop(); 

     int statusCode = response.getStatusLine().getStatusCode(); 
     if (statusCode != 200) { 
      answer = retryOrHandleError(numOfTries, routingRequestUrl, answer, response, statusCode); 
     } else { 
      String bodyAsString = EntityUtils.toString(response.getEntity()); 
      answer.completeRoutingResponse = handleSuccess(bodyAsString); 
      answer.latency = stopWatch.elapsed(TimeUnit.MILLISECONDS); 
      handleErrorInBody(routingRequestUrl, answer, bodyAsString); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
     System.out.println(e.getMessage()); 
    } 
    handleNullResponse(answer); 
    return answer; 
} 

e

@Override 
    public E2EResult sendBaselineRoutingRequestsInParallel(E2EResult e2EResult, List<String> routingRequestsList) { 
     List<Callable<Void>> callables = new ArrayList<>(); 
     for (int i = 0; i < routingRequestsList.size(); i++) { 
      final int position = i; 
      callables.add(() -> { 

//calls sendRoutingRequestString() 

       synchronized (e2EResult) { 
        e2EResult.addResponse(relativePosition, requestPosition, routingResponse); 
       } 
       return null; 
      }); 
     } 
     ExecutorService executorService = Executors.newFixedThreadPool(10); 
     try { 
      executorService.invokeAll(callables); 
      executorService.shutdown(); 
      executorService.awaitTermination(1, TimeUnit.MINUTES); 
     } catch (InterruptedException e) { 
      e.printStackTrace(); 
      throw new RuntimeException(e); 
     } 
     return e2EResult; 
    } 

Quando il codice chiama questo URL si ritorna sempre 504.

tuttavia quando ho messo via il browser Chrome non ho mai ottenere 504.

Ho pensato che potrebbe essere un problema di stress. Ma anche quando chiamo solo pochi URL nel mio codice ottengo 504 solo per questo URL specifico.

Cosa può essere? un bug in maglia per un lungo URL?

Answer 1

Sembra che ti aspetti una risposta JSON. In alcuni casi ho notato che l'analisi JSON potrebbe avere problemi in particolare con il contenitore di jersey incorporato, ad esempio eseguendolo come parte di un test JUnit.

Quando si esegue l'URL direttamente contro il browser, non si analizza il JSON poiché si sta visualizzando il risultato in JSON dal browser. I browser sono molto resistenti alla gestione di JSON.

Controllare e assicurarsi che il codice responsabile della creazione dell'oggetto JSON sia corretto.

Answer 2

504 Timeout gateway - Indica che il servizio di bilanciamento del carico ha chiuso una connessione perché una richiesta non è stata completata entro il periodo di timeout di inattività.

Causa: l'applicazione impiega più tempo a rispondere rispetto al timeout di inattività configurato.

Monitorare HTTPCode_ELB_5XX e Latency CloudWatch metrics. Se c'è un aumento di queste metriche, potrebbe essere dovuto al fatto che l'applicazione non risponde entro il periodo di timeout di inattività. Per i dettagli sulle richieste che stanno scadendo, abilitare i registri di accesso sul bilanciamento del carico e rivedere i codici di risposta 504 nei registri generati da Elastic Load Balancing. Se necessario, è possibile aumentare la capacità di back-end o aumentare il timeout di inattività configurato in modo che possano essere completate lunghe operazioni (come il caricamento di un file di grandi dimensioni).

Per configurare le impostazioni di timeout di inattività per un pool di applicazioni

Interfaccia utente -> Per utilizzare l'interfaccia utente

1.Open Gestione IIS. Per informazioni sull'apertura di Gestione IIS, vedere Aprire il gestore di IIS (IIS 7).

2. Nel riquadro Connessioni, espandere il nodo del server e fare clic su Pool di applicazioni .

3. Nella pagina Pool di applicazioni, selezionare il pool di applicazioni di cui si desidera specificare le impostazioni di timeout di inattività, quindi fare clic su Impostazioni avanzate nel riquadro Azioni.

4. Nella casella Idle Timeout (minuti), digitare un numero di minuti, quindi fare clic su OK.

riga di comando

Per configurare il valore di timeout di inattività per un pool di applicazioni, utilizzare la seguente sintassi: appcmd set config /section:applicationPools /[name=' string '].processModel.idleTimeout: timeSpan

dove stringa è il nome del pool di applicazioni che si desidera per configurare. La variabile timeSpan è il periodo di tempo in cui il processo di lavoro oi processi nel pool di applicazioni sono considerati inattivi . Il formato per timeSpan è d.hh: mm: ss dove d è il numero di giorni facoltativo e hh: mm: ss è il numero di ore, minuti e secondi in cui arrestare il processo di lavoro. Ad esempio, per impostare il valore di timeout di inattività per 30 minuti per un pool di applicazioni denominato Marketing, digitare quanto segue al prompt dei comandi, quindi premere INVIO:

appcmd set config /section:applicationPools /[name=' Marketing '].processModel.idleTimeout:0.00:30:00

La procedura in questo argomento influisce sugli elementi di configurazione seguenti:

attributo idleTimeout dell'elemento <processModel> sotto <add> sotto <applicationPools>

Utilizzare i seguenti WMI classi, i metodi o le proprietà per eseguire questa procedura:

ApplicationPool.ProcessModel.IdleTimeout proprietà
