从json获取经度和纬度

Question

请告诉我，我怎么能得到lat＆amp;我的rails-app现在呢？ -

#<HTTParty::Response:0x7fbda4055780 parsed_response={"ip"=>"74.125.232.229", "city"=>{"id"=>5375480, "lat"=>37.38605, "lon"=>-122.08385, "name_ru"=>"Маунтин-Вью", "name_en"=>"Mountain View", "name_de"=>"Mountain View", "name_fr"=>"Mountain View", "name_it"=>"Mountain View", "name_es"=>"Mountain View", "name_pt"=>"Mountain View", "okato"=>"", "vk"=>0, "population"=>74066}}

Answer 1

假设您将HTTParty响应分配给这样的变量：

r = #<HTTParty::Response:0x7fbda4055780 parsed_response={"ip"=>"74.125.232.229", "city"=>{"id"=>5375480, "lat"=>37.38605, "lon"=>-122.08385, "name_ru"=>"Маунтин-Вью", "name_en"=>"Mountain View", "name_de"=>"Mountain View", "name_fr"=>"Mountain View", "name_it"=>"Mountain View", "name_es"=>"Mountain View", "name_pt"=>"Mountain View", "okato"=>"", "vk"=>0, "population"=>74066}}

然后你可以获取解析后的响应（我喜欢让它具有无差别的访问权限），如下所示：

r = r.parsed_response.with_indifferent_access

然后你可以这样做：

lat = r[:city][:lat]
lon = r[:city][:lon]
