Making a Dynamic Service Portal File Download Widget

[jmiskey]

We currently have a few Catalog Items on our Service Portal where users need to download a file that we have uploaded to ServiceNow.  So, we have create custom Service Portal Widgets.  They are pretty basic, here is all there is to them:

Body HTML template section:

<div>

<a href="/sys_attachment.do?sys_id=...">Link text to display</a>

</div>

Client Controller section:

function ($scope,$location) {
  $scope.download = function(path){
  $location.path(path);
  };
}

So, the sys_id and "text to display" are hard-coded right inside our widget.  And then in our Catalog Item, we use a "Label with Macro" variable, filling out the Widget box with the name of our widget.

This works great, but we currently have a separate widget for each file.  I have a whole bunch more files to add for a bunch more Catalog Items that I need to create, and instead of creating a bunch more widgets, I would like to create one dynamic file download widget, where I can just feed in the sys_id of the attached file and the text I would like to display.  I am just unsure how to update the widget, and how to feed in the values (attributes, maybe?).

I imagine this is probably a pretty easy request for an experienced widget creator, but I am pretty new to the widget world, and just getting my feet wet here.
