[Qt-interest] Discover IP address and Turn Into QUrl

[Robert Escott]

I'm not quite sure what you're doing inside the QUrl constructor but have you tried

Request.setUrl(QUrl(QString("http://%1/something.cgi").arg(ip)));

This is assuming that ip is already in dotted IP format.

Qt Interest,

     I have been trying to get my IP address (on embedded Qt with ARM) rather than set it statically.  So far I have successfully been able to get the IP and turn it into a char* where I can printf( "%s",ip); and have it return the IP address as a dotted decimal (192.168.1.20). However, I am trying to use the IP in an HTTP query to invoke a cgi script.  This works perfectly when I set the IP address statically. Here is an example assuming ip is a (char *) with the IP already set:

 

QNetworkAccessManager *manager = new QNetworkManager(this);

QNetworkRequest request;

Request.setUrl(QUrl(("http://%s/something.cgi", ip)));

QNetwork Reply *reply = manager->get(request);

 

Testing with printf's and such showed that this should work, I end up getting http://192.168.1.20/something.cgi but it does not start the script.  Am I missing something obvious?
