QNetworkAccessManager make another request after response

Pedro Vicente

I have a QNetworkAccessManager instance

https://doc.qt.io/qt-6/qnetworkaccessmanager.html

m_network = new QNetworkAccessManager(this);
connect(m_network, &QNetworkAccessManager::finished, this, &LabelEntry::on_finished);

that requests an URL.
example : http://100.36.4.152/index.html

the response is obtained in a QLabel class and in it I extract this URL, like this

void LabelEntry::on_finished(QNetworkReply* reply)
{
  QNetworkRequest request = reply->request();
  QUrl url = request.url();
  QString path = url.path();
  QString url_path = url.url();
  QString url_main = url_path.remove(path);

  QByteArray data = reply->readAll();
  QString html = QString(data);

this prints for url_main

http://100.36.4.152

and variable 'html' has the HTML buffer

Next, I am going to extract the HTML tags from this buffer (irrelevant how to do it for this);

http://100.36.4.152/index.html

I obtained, that the HTML has an image tag in it, for example

icons/ubuntu-logo.png

so, the complete URL of this image is

http://100.36.4.152/icons/ubuntu-logo.png

Now, I need to get this image.

Question , what would be the best way to do it?
This was already obtained in a QNetworkAccessManager instance, so, one way, would be to define yet another for this request ? and where to define and call it, from the Qt frameworkt?
locally from this class (LabelEntry), or define another class for the new request ?

Gracias

Hi,

Use the same QNAM, however rather than connecting its finished signal, do it for the reply of your request so you can properly handle the two request independently.
