c++ - How can i get content of web-page

Question

i'm trying to get web-page data in string that than i could parse it. I didn't found any methods in qwebview, qurl and another. Could you help me? Linux, C++, Qt.

EDIT:

Thanks for help. Code is working, but some pages after downloading have broken charset. I tried something like this to repair it:

QNetworkRequest *request = new QNetworkRequest(QUrl("http://ru.wiktionary.org/wiki/bovo"));

request->setRawHeader( "User-Agent", "Mozilla/5.0 (X11; U; Linux i686 (x86_64); "
                       "en-US; rv:1.9.0.1) Gecko/2008070206 Firefox/3.0.1" );
request->setRawHeader( "Accept-Charset", "win1251,utf-8;q=0.7,*;q=0.7" );
request->setRawHeader( "charset", "utf-8" );
request->setRawHeader( "Connection", "keep-alive" );

manager->get(*request);

Any results =(.

Have you looked at QNetworkAccessManager? Here's a rough and ready sample illustrating usage:

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!

}

In your in your handler for the finished signal you will be passed a QNetworkReply object, which you can read the response from as it inherits from QIODevice. A simple way to do this is just call readAll to get a QByteArray. You can construct a QString from that QByteArray and do whatever you want to do with it.
