To round out implementation of a simple path for users to access
HttpClient like Open or Net::HTTP, create :request_url method which
takes a single URL parameter, uses :request_opts_from_url to build
the request configuration for Rex::Proto::Http::Client, executes
a GET request with it, and disconnects the client unless keepalive
is specified as the second parameter to :request_url.
Example usage of functionality is implemented in http_pdf_authors.
To address the complexity which comes with the flexibility offered
by Rex::Proto::Http::Client and its Msf mixin descendant, a simple
process needs to be implemented for issuing a request using only
the URL string in order to provide ease of access to users who may
not have the time to study how these clients work in detail.
Implement :request_opts_from_url in Msf's HttpClient mixin such as
to extract the options required for :send_request_* from a URL
string passed into the method. This approach reduces HTTP requests
in the mixin to `send_request_raw(request_opts_from_url(url))` when
`url` is just a string.
Implement this approach in the http_pdf_authors gather module to
further reduce infrastructure complexity around the simple need to
acquire PDF files via HTTP/S.
Testing:
Local to this module only, and in Pry of course. Seems to work...
Replace Net::HTTP usage with proper Rex::Proto::Http::Client via
the Msf module mixin. Generate the request opts from the same URI
parsed URL string, execute a one shot GET request, disconencting
after reciept of results. Depending on the response code, either
pass back an empty StringIO or if its 200, a StringIO(res.body).
