HTTParty Google在原点和目的地之间映射方向。

Question

class GoogleMap
  include HTTParty
  base_uri 'http://maps.googleapis.com'

  attr_accessor :origin, :destination

   def initialize(service, page)
    @options = { query: {origin: origin, destination: destination} }
  end

  def directions
    self.class.get("/maps/api/directions/json", @options)
  end
end

irb(main):001:0> g = GoogleMap.new("montreal", "toronto")
=> #<GoogleMap:0x007fcaeeb88538 @options={:query=>{:origin=>nil, :destination=>nil}}>
irb(main):002:0> g.directions
=> #<HTTParty::Response:0x7fcaeeb60b00 parsed_response={"error_message"=>"Invalid request. Missing the 'origin' parameter.", "routes"=>[]...

irb(main):001:0> g = GoogleMap.new("montreal", "toronto")
=> #<GoogleMap:0x007fcaeeb88538 @options={:query=>{:origin=>montreal, :destination=>toronto}}

g.Directions我得到http://maps.googleapis.com/maps/api/directions/json?origin=montreal&destination=toronto&sensor=false的输出
