Question

result = Geocoder.search("white house, Washington DC")

如何引用以下属性？

我试过r.first.data["address_components"]，但是我不能引用过去这个，比如我想拉[type="premise"]["long_name"]，等等。如果我想要县，我可以使用 r.first.country 并且有效，但是 r.first.premise 无效。

  @data=
   {"address_components"=>
     [{"long_name"=>"The White House",
       "short_name"=>"The White House",
       "types"=>["premise"]},
      {"long_name"=>"1600", "short_name"=>"1600", "types"=>["street_number"]},

Answer 1

Geocoder::Result::Googleclass 的文档在这里：http://www.rubydoc.info/github/alexreisner/geocoder/master/Geocoder/Result/Google It has lots of useful methods, including address_components_of_type。

看来你要的是这个：

res1 = result.first
premises = res1.address_components_of_type(:premise)
puts premises[0]['long_name']

Answer 2

我在我的代码中添加了以下内容，现在运行良好。

module Geocoder::Result
  class Google < Base

    def premise
       if premise = address_components_of_type(:premise).first
         premise['long_name']
       end
    end

    def premise_code
       if premise = address_components_of_type(:premise).first
         premise['short_name']
       end
    end

    def subpremise
       if subpremise = address_components_of_type(:subpremise).first
         subpremise['long_name']
       end
    end
    def subpremise_code
       if subpremise = address_components_of_type(:subpremise).first
         subpremise['short_name']
       end
    end
  end
end

Answer 3

tl;dr：我认为有一套很好的 docs for Geocoder::Results::Google 可以提供您想要的所有答案。

鉴于上面的结果，这应该有效：

r = result.first
r.types
# => ["premise"]
r.country
# => "United States"
r.country_code
# => "US"
r.formatted_address
# => "The White House, 1600 Pennsylvania Ave NW, Washington, DC 20500, USA"
