How To Get HTTP Status Codes From QWebEngineView?

tshoats

Hello, sorry if i posted twice, just found out theres a QWebEngine forum section. I've been looking through the docs to find a way to return the http status codes from a QWebEngineView after loading a page, and making a request. I understand that QWebEngineView does not interact with QNetWorkAccessManager which would make this a breeze to accomplish. So is there any other way to get the HTTP status code from a request using QWebEngineView?? I tried multiple ways including RequestInterceptor. Below is a snippet of my attempt using RequestInterceptor, but its not giving me actual HTTP Status codes, just constant values, which is what I dont want..

//your code here   
        /*************requestinterceptor.h**************/
#ifndef REQUESTINTERCEPTOR_H
#define REQUESTINTERCEPTOR_H

#include <QWebEngineUrlRequestInterceptor>
#include <QWebEngineUrlRequestInfo>
#include <QDebug>
#include <QUrl>

class RequestInterceptor : public QWebEngineUrlRequestInterceptor
{
public:
  explicit RequestInterceptor(QObject * parent = Q_NULLPTR);
  virtual void interceptRequest(QWebEngineUrlRequestInfo & info) Q_DECL_OVERRIDE;
};
#endif // REQUESTINTERCEPTOR_H

/*************requestinterceptor.cpp***************/

#include "requestinterceptor.h"

RequestInterceptor::RequestInterceptor(QObject * parent)
  :QWebEngineUrlRequestInterceptor(parent){}

void RequestInterceptor::interceptRequest(QWebEngineUrlRequestInfo & info)
{
  QString rsrct = "";
  switch(info.resourceType()){
      case 0:rsrct="ResourceTypeMainFrame = 0, --> top level page";break;
      case 1:rsrct="ResourceTypeSubFrame, --> frame or iframe";break;
      case 2:rsrct="ResourceTypeStylesheet, --> a CSS stylesheet";break;
      case 3:rsrct="ResourceTypeScript, --> an external script";break;
      case 4:rsrct="ResourceTypeImage, --> an image (jpg/gif/png/etc)";break;
      case 5:rsrct="ResourceTypeFontResource, --> a font";break;
      case 6:rsrct="ResourceTypeSubResource, --> an other subresource.";break;
      case 7:rsrct="ResourceTypeObject, --> an object (or embed) tag for a plugin,";break;
      case 8:rsrct="ResourceTypeMedia, --> a media resource.";break;
      case 9:rsrct="ResourceTypeWorker, --> the main resource of a dedicated worker.";break;
      case 10:rsrct="ResourceTypeSharedWorker, --> the main resource of a shared worker.";break;
      case 11:rsrct="ResourceTypePrefetch, --> an explicitly requested prefetch";break;
      case 12:rsrct="ResourceTypeFavicon, --> a favicon";break;
      case 13:rsrct="ResourceTypeXhr, --> a XMLHttpRequest";break;
      case 14:rsrct="ResourceTypePing, --> a ping request for <a ping>";break;
      case 15:rsrct="ResourceTypeServiceWorker, --> the main resource of a service worker.";break;
      case 16:rsrct="ResourceTypeUnknown";break;

      default : rsrct="Unknown type";break;
  }

qDebug()<<"\t"<<Q_FUNC_INFO<<":\n\t\t" << "WebUrlRequestInterceptor::interceptRequest    " <<info.requestMethod()
       <<"\r\n  "<<info.requestUrl()<<"   "<<rsrct      <<"\r\n";

}

/*************mainwindow.cpp***************/
  const QUrl url("http://google.com");
  view = new WebView();
  view = new QWebEngineView();
  interceptor = new RequestInterceptor(view);
  profile = new QWebEngineProfile(view);
  profile->setRequestInterceptor(interceptor);
  page = new QWebEnginePage(profile,view);
  view->setPage(page);

I have the same issue. Did you find a solution for this?

Does the (rather terse) answer at https://stackoverflow.com/a/53516333/489865 help you?
Otherwise you might have to resort to https://forum.qt.io/topic/80372/qml-webengineview-does-not-return-http-page-errors/2# ?
