Ruby client doesn't correctly retrieve requests with a body

[jnormington]

Here is a very basic reproducible rspec

RSpec.describe 'Mockserver retrieve requests' do
  it 'returns requests' do
    `curl -XPOST localhost:2000/message -d 'Hello this is a message'`

    msc = MockServer::MockServerClient.new('localhost', 2000)
    req = MockServer::Model::Request.new(method: :POST, path: '/message')

    #It will error on the below line    

    puts msc.retrieve(req)
   end
end

The error that comes out from retrieving the request from mockserver is

Hashie::CoercionError: Cannot coerce property :body from String to MockServer::Model::Body: undefined method `each_pair' for "Hello this is a message":String

It appears that the coercian isn't possible because the mockserver isn't sending the body type along to the request.

There is a PR which fixes the ruby client https://github.com/jamesdbloom/mockserver/pull/238 but my gut feeling tells me it ideally should returned from the overridden toString method in all the classes extending Body like StringBody below

Closing as this issue will be fixed once the ruby client is re-written, that will happen once support for generating clients from Open API 3.0 becomes available https://github.com/swagger-api/swagger-codegen. Closing this issue as related to #182.
