I am trying to access a web URL through Script Editor Section. After the URL is fetched I want to pass the username and password through it. I am not able to work out how to do it.
If this doesn't work, you can either have a look at QVSource, which offers some more connectors, or try creating a batch script (which you can execute also from your QV script) using e.g. cURL that connects to your site, fetches the data and stores it to a flat file. Then let QV read this file.
