httpunit funktioniert nicht, wenn Klasse JFrame erweitert

Question

Bei dem Versuch, sich an https://www.okcupid.com/login mit der httpunit-Bibliothek anzumelden, wird der folgende Code erfolgreich ausgeführt.

Wenn ich jedoch die Klasse mit JFrame erweitern, damit ich die Benutzeroberfläche erstellen kann, schlägt die Ausführung fehl. Die POST Anforderung wird ordnungsgemäß abgeschlossen, aber die GET Anfrage schlägt fehl, wenn HtmlPage page = wc.getPage(url)

ausgeführt wird. Unter dem Code habe ich die Ausgabe für beide Szenarien.

Works, es sei denn Haupt erstreckt JFrame

public class Main /* extends JFrame */ { 
    static boolean isConnecting = false; 
    public static void main(String[] args) { 
     new Main(); 
    } 

    public Main() { 
     login(); 
    } 

    public void login() { 
     try { 
      /* POST */ 
      WebClient wc = new WebClient(); 
      URL url = new URL("https://www.okcupid.com/login"); 
      WebRequest requestSettings = new WebRequest(url, HttpMethod.POST); 
      requestSettings.setRequestBody("username=myLogin&password=myPassword&okc_api=1"); 
      Page redirectPage = wc.getPage(requestSettings);/* unique */ 
      Set<Cookie> cookies = wc.getCookieManager().getCookies(); 

      /*GET */ 
      wc = new WebClient(); 
      for (Cookie cookie : cookies) { 
       wc.getCookieManager().addCookie(cookie); 
      } 
      HtmlPage page = wc.getPage(url); 
      WebResponse response = page.getWebResponse(); 
      String content = response.getContentAsString(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
    } 
} 

Ausgabe, wenn Haupt JFrame erweitert

Answer 1

Ich habe herausgefunden, warum das passiert und wie es funktioniert, aber ich weiß immer noch nicht, wie es funktioniert, wenn man JFrame erweitert.

1. Wenn Sie htmlunit zur Bearbeitung von URL-Anfragen verwenden, entfernen Sie zuerst die JFrame-Erweiterung. Jetzt wird der Code ausgeführt, startet die Benutzeroberfläche jedoch immer noch nicht.

2. Anstatt die Erweiterung der Klasse für JFrame zu verwenden, erstellen Sie in dem Teil, in dem Sie die Erweiterung benötigen, eine neue JFrame-Instanz. Verwenden Sie dann diese Instanz von JFrame, um alle erforderlichen Eigenschaften und Aktionen zu deklarieren.
