I need to get title of webpage

jsulm

@Armin If you used Qt Online INstaller then you already have the Qt Maintenance Tool - see in Qt installation directory.

My maintance tool problem solved.
but i dont know how i must get title of a html page.

jsulm

@Armin You mean you want to extract title from:

<head>
	<title>General and Desktop | Qt Forum</title>

right?
Then you can just sent a GET request using http://doc.qt.io/qt-5/qnetworkaccessmanager.html and then parse the response (you can use a regular expression to extract the title from <title>...</title>).
From the link above:

QNetworkRequest request;
request.setUrl(QUrl("http://qt-project.org"));
request.setRawHeader("User-Agent", "MyOwnBrowser 1.0");

QNetworkReply *reply = manager->get(request);
connect(reply, SIGNAL(readyRead()), this, SLOT(slotReadyRead()));
connect(reply, SIGNAL(error(QNetworkReply::NetworkError)),
        this, SLOT(slotError(QNetworkReply::NetworkError)));
connect(reply, SIGNAL(sslErrors(QList<QSslError>)),
        this, SLOT(slotSslErrors(QList<QSslError>)));

@jsulm Thanks
But i want to get title and i don't need to set. i need get and no set

jsulm

@Armin Where did I say anything about set?

Armin

@jsulm Thanks
In this line if i am not mistaken you set the title
request.setRawHeader("User-Agent", "MyOwnBrowser 1.0");
But i want to store the title in a QString

jsulm

@Armin No this line does not set any titles, why do you think so? Did you read the documentation? You can remove this line. It is not needed for your use-case.

Armin

@jsulm Thanks

now , all i want is to get url in title ( <title> ... </title> ) and put it on QString.

jsulm

@Armin You can use a regular expression after you got the response from the server to extract the title.

Armin

@jsulm Thanks
If that file isn't html , and be mp4 or pdf
So what do i do ?

jsulm

@Armin Sorry, but you asked how to get the title of a web page, right?
What do you want to do with mp4 or pdf?

Armin

@jsulm Thanks
Right , i asked about webpage
How can i name of download file?
Thanks

jsulm

@Armin The name of the file you're downloading is already in the URL, isn't it? Usually you know it in advance.
Like: http://download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run
File name is: qt-unified-linux-x64-online.run
Or do you want to know which files you can download from a web site? Then look for for something like:

<a href="http://download.qt.io/official_releases/online_installers/qt-unified-linux-x64-online.run">Qt Online Installer for Linux (64-bit)</a>

Armin
