Solved Load a Web source code into a String or QString to parse

[Josz]

Hello, (please any help will be wellcomed)
I can display a web with the next commands

QWebView *view = new QWebView(nullptr);
view->load(QUrl("https://www.elmundo.es/espana.html"));
view->show();

But how can I get the source code into a string to analyze and parse?

Thanks in advance

@josz Hi,

Using QNetworkAccessManager:

QNetworkAccessManager *manager = new QNetworkAccessManager(this);
connect(manager, &QNetworkAccessManager::finished,
        this, &MyClass::replyFinished);

manager->get(QNetworkRequest(QUrl("http://qt-project.org")));

MyClass::replyFinished(QNetworkReply *reply){
    if(QNetworkReply::NoError == reply.error())
        QString html = reply.readAll();
    else //Error
}

@josz It seems (see this post) you can also get the html code using QWebFrame::toHtml()

QString html = view ->page()->currentFrame()->toHtml();

Hi @gojir4 thank you , I used the next code, but didn't work and I don't know why
source : https://stackoverflow.com/questions/1053099/how-can-i-get-content-of-web-page

class MyClass : public QObject
{
Q_OBJECT

public:
    MyClass();
    void fetch(); 

public slots:
    void replyFinished(QNetworkReply*);

private:
    QNetworkAccessManager* m_manager;
};


MyClass::MyClass()
{
    m_manager = new QNetworkAccessManager(this);

    connect(m_manager, SIGNAL(finished(QNetworkReply*)),
         this, SLOT(replyFinished(QNetworkReply*)));

}

void MyClass::fetch()
{
    m_manager->get(QNetworkRequest(QUrl("http://stackoverflow.com")));
}

void MyClass::replyFinished(QNetworkReply* pReply)
{

    QByteArray data=pReply->readAll();
    QString str(data);

    //process str any way you like!
   qDebug() << data;
}

Agghhh. I had the QApplication a(argc, argv); and return a.exec(); commented. So, it was not an event loop.

Sorry (and thank you very much).

It worked.
