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();



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().
