How to see the http requests sent by the application (mac)?

Question

JavaScript

There is a QT application, which is a QWebView with small goodies. I need to see what requests this QWebView sends (an html + js application is loaded in it that sends ajax requests).
For windows, I always used the fiddler program, on a poppy its port does not work - it does not read requests from this application. The rest of the applications either did not start at all, or did not say anything intelligible.
Who knows a good app for mac os? Or even better, to see the console of this webkit.. There are no application sources.
