How can I open and read text file with url?

[mangekoyu]

I want read a rext file from url. I tried this code;

QFile file1("http:/website.com/dtl/version.txt");
     file1.open(QIODevice::ReadOnly | QIODevice::Text);
     QString dataString1 = file1.readAll();
     qDebug() << dataString1;

And I got this error;

QIODevice::read (QFile, "http:\\whilone.com\dtl\version.txt"): device not open
""

How Can I fix this issue? Please can someone help me?

@mangekoyu You need to download that file first to your machine.
