How do you pass additional parameters to the request interceptor before or after functions?

One option is that the default value of "this" inside the "before" function is the interceptor object itself. It looks like "const" also has scope inside the "before" function. Does that sound useful? Example: https://codepen.io/noash/pen/ZELpXBG?editors=1000
 

If not, it would be easier to have a simplified repro case to diagnose. I'd like to see how you are currently using bind.

@RobertScheitlin__GISP - I'm not sure I understand. Are you asking for how to send two or more parameters to the before/after functions?

Noah,

   The issue I am having is that the scope of the inteceptor before or after functions have no access to vars or any scope outside the function. So I have tried .bind(this) and every other trick I am aware of. So I am wondering if you can pass an additional parameter or bind to the outside scope of the function.

Ok, I think I understand better now. I don't know an answer off the top of my hand, but I will look into it.
