_uri.path = '/posts'               # => "/posts"
req = Net::HTTP::Post.new(_uri)    # => #<Net::HTTP::Post POST>
req.body = '{"title": "foo","body": "bar","userId": 1}'
req.content_length = req.body.size # => 42
req.content_type = 'application/json'
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end # => #<Net::HTTPCreated 201 Created readbody=true>
