In general, the params hash (method 'params') is always available to
your controller actions. You literally wrote how your params hash
looks like (your incoming request parameters), so it's just plain Ruby
code to retrieve the contents of the hash:
params[:message] returns the hash {'body' => 'this is the reply'}
so params[:message]['body'] would give you the string 'this is the
reply'
Beside checking a Rails book, I found that most useful is a good grasp
of Ruby itself (the 'pickaxe' book is a good start). You can learn
Rails pretty much on the go, but good Ruby skills are really valuable
to move on quickly.
