從json獲取經緯度

Question

請告訴我，我現在如何才能獲得緯度& lon？ -

#<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

假設你分配給這樣的變量您HTTParty迴應：

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}} 

然後你就可以抓住解析響應（我喜歡它冷漠的訪問），像這樣：

r = r.parsed_response.with_indifferent_access 

然後你就可以這樣做：

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