HTTP GetRequest workflow

Inizia esaminando i due workflow descritti intorno a BH.Engine.HTTP.Compute.GetRequest(url), GetRequest e HTTPAdapter. Confronta gli approcci proposti Adapter/Pull, adattatore implicito ed Execute, incluso l’entry point proposto BH.Adapter.HTTP.PullRequest(url) e le implicazioni per la UI. Il lavoro sarebbe completato solo dopo aver concordato un workflow e una terminologia, prima di poter definire l’ambito dell’implementazione.

Have been playing with the OpenStreetMap_Toolkit leveraging the HTTP_Toolkit 😍 😍 😍

Did lead to some thoughts around potentially consolidating the http requests to more clearly align with other areas of the BHoM. A few notes for comment - @epignatelli @alelom picking up from our chat earlier. Low priority and great to enable these experiments as some thinking needed I think to create a satisfactorily slick, consistent and clear work flow.

There are currently two implementations of HTTP requests -

1. following the Adapter/Pull work flow
   Feeding a GetRequest into a Pull with also a HTTPAdapter
2. A simpler workflow mirroring the expression of a single http request string. Through
   BH.Engine.HTTP.Compute.GetRequest(url) which directly returns the string response

The 2. above is neat - but needs to move out of Engine Compute as is externally interfacing.

The challenge we have is that a traditionally formatted http request contains the domain (i.e. source or adapter in BHoM terms) actually embedded in line with the request itself.
Our standard adapter Pull and Push workflows have naturally separated these concepts out.

Useful to align terminology and concepts where we can - but also be intuitive and respect conventions of the software/platforms we are adapting to.

The main comment I discussed with @epignatelli was to ensure clarity that a link (or adapter) with the outside world to BHoM is still being made. Even if not a standard Adapter -> Pull

So few options:

a)
This has redundant information for http as described above.

b)
Could separate out domain and rest of request arguments for the http string - but I think this is unintuitive if already familiar with performing http requests. Others opinions here are welcome - but feels we are forcing too hard into BHoM format!?

c)
Could allow not specifying adapter - where is implicit from the request?

d)
Could then enable implicit casting of correctly such that work flow might allow

e)
An option that might make sense is to achieve very close to the original BH.Engine.HTTP.Compute.GetRequest(url) , respecting the current exception of http, but migrating it to an Adapter NameSpace such that we could have something like BH.Adpater.HTTP.PullRequest(url).

This would not currently reflect into UI - so considerations needed there.

f)
Another final option would be that we do this as an extension of the Execute...

With this option I think we come close to some of the ideas we had before, where we considered implementing Executes with the actual Adapter not needing to be explicitly defined as additional input - being implicit in the Method you were executing.
This came up originally from discussions about executing external Python scripts etc.
Wonder if this might be a way forward?

Sorry for long notes - wanted to capture thoughts and discussions.
Perhaps one to pick up over a call?
