How to make a HTTP request in QTJambi

[divanshu]

How I can make a HTTP request in QT jambi.

QUrl qURL = new QUrl(url);
		System.out.println(qURL.encodedHost());
		QHttpRequestHeader header = new QHttpRequestHeader("GET", "/index.html");
 
		header.setValue("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows 98)");
		header.setValue("Pragma", "no-cache");
 
		header.setValue("Host","miniorb.in" );
 
		QObject qObject = new QObject();
 
		QHttp qHttp = new QHttp();
		qHttp.setHost("minirob.in");
		//qHttp.currentRequest();
		qHttp.request(header);
 
 
 
 
 
		QByteArray xyz = qHttp.readAll();

QUrl qURL = new QUrl(url);
		System.out.println(qURL.encodedHost());
		QHttpRequestHeader header = new QHttpRequestHeader("GET", "/index.html");

		header.setValue("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows 98)");
		header.setValue("Pragma", "no-cache");

		header.setValue("Host","miniorb.in" );

		QObject qObject = new QObject();

		QHttp qHttp = new QHttp();
		qHttp.setHost("minirob.in");
		//qHttp.currentRequest();
		qHttp.request(header);
		




		QByteArray xyz = qHttp.readAll();

I tried to connect with the page in this way. but when I am trying to read it, it is giving me blank output. help me how i can fix it.


Thanks In advance !!!

You must connect void QHttp::requestFinished ( int id, bool error ) or QHttp::done ( bool error ) to some of your slots and then use readAll().
