Ruby on rails rails上的错误uri google目录api

我正在尝试向rails上的google directions api发送请求，我尝试了一些事情，这就是我现在所拥有的-

 url = URI.parse(requested_url)
 full_path = (url.query.blank?) ? url.path : "#{url.path}?#{url.query}"
 the_request = Net::HTTP::Get.new(full_path)
 the_response = Net::HTTP.start(url.host, url.port) { |http| http.request(the_request) }
 raise "Response was not 200, response was #{the_response.code}" if the_response.code !=   "200"
 return the_response.body

但它是一个坏的URI（不是URI？）：“ת㪠בבבב”和destination=“יש㪡םם”和sensor=false

如果将其粘贴到浏览器上，则返回ok
