如何使用 vala(gtk) 从某个站点（例如 www.google.com）获取 html 代码？我正在使用 Val(a)IDE 进行编程。
如果有人需要，这是我的代码：
public class Main
{
public static int main (string[] args)
{
Gtk.init (ref args);
Gtk.Window window = new Gtk.Window (Gtk.WindowType.TOPLEVEL);
window.title = "First test app";
window.set_default_size (320, 420);
window.position = Gtk.WindowPosition.CENTER;
window.destroy.connect(Gtk.main_quit);
var buttonBack = new Gtk.Button.with_label ("<");
var buttonForward = new Gtk.Button.with_label (">");
var buttonRefresh = new Gtk.Button.with_label ("Refresh");
var buttonStop = new Gtk.Button.with_label ("Stop");
buttonBack.set_size_request (20, 40);
buttonForward.set_size_request (20, 40);
buttonRefresh.set_size_request (20, 40);
buttonStop.set_size_request (20, 40);
//window.add (buttonBack);
var label1 = new Gtk.Label ("There will be something! :)");
label1.set_size_request (320,380);
//window.add (label1);
var hbox1 = new Gtk.HBox (true, 0);
var vbox1 = new Gtk.VBox (false, 0);
//var html = new Gtk.Widget();
//var empty = new Gtk.Label ("");
//empty.set_size_request(300, 10);
hbox1.add (buttonBack);
hbox1.add (buttonForward);
hbox1.add (buttonRefresh);
hbox1.add (buttonStop);
//hbox1.add (empty);
vbox1.add (hbox1);
vbox1.add (label1);
window.add (vbox1);
window.show_all ();
Gtk.main ();
return 0;
}
}
