從Google地圖中的街道地址獲取區域名稱

Question

我正在開發一個網站，在該網站中繪製區域的統計數據並在Google地圖上顯示。

如果您在Google地圖中搜索「Harlem New York，NY USA」或「University Heights Bronx，NY USA」，它會遮擋整個區域。我將展示這一領域，並將找出一種方法來顯示帶有統計數據的標記。

但是，考慮到用戶將輸入地址，例如「500W133rdSt，紐約，紐約州10027，美國」，是否有可能使用一些GoogleMap API或其他東西來檢索區域名稱（Harlem），從提到的街道地址？

Answer 1

您可以使用Google Maps Geocoding API （爲了使用它，你需要一個Gecoding API key）

對於你的榜樣「500瓦第133街，紐約，NY 10027，USA」你可以調用API在以下方法： https://maps.googleapis.com/maps/api/geocode/json?address=500%20W%20133rd%20St,%20New%20York,%20NY%2010027,%20USA

如果提供正確的密鑰，你應該得到以下JSON：

{ 
    "results" : [ 
     { 
     "address_components" : [ 
      { 
       "long_name" : "500", 
       "short_name" : "500", 
       "types" : [ "street_number" ] 
      }, 
      { 
       "long_name" : "West 133rd Street", 
       "short_name" : "W 133rd St", 
       "types" : [ "route" ] 
      }, 
      { 
       "long_name" : "Upper Manhattan",

       "types" : [ "neighborhood", "political" ] 
      }, 
      {

      }, 
      { 
       "long_name" : "New York County", 
       "short_name" : "New York County", 
       "types" : [ "administrative_area_level_2", "political" ] 
      }, 
      { 
       "long_name" : "New York", 
       "short_name" : "NY",

      { 
       "long_name" : "7302", 
       "short_name" : "7302", 
       "types" : [ "postal_code_suffix" ] 
      } 
     ], 
     "formatted_address" : "500 W 133rd St, New York, NY 10027, Stany Zjednoczone", 
     "geometry" : { 
      "bounds" : { 
       "northeast" : { 
        "lat" : 40.8176249, 
        "lng" : -73.9532346 
       }, 
       "southwest" : { 
        "lat" : 40.8176127, 
        "lng" : -73.9532442 
       } 
      }, 
      "location" : { 
       "lat" : 40.8176127, 
       "lng" : -73.9532442 
      }, 
      "location_type" : "RANGE_INTERPOLATED", 
      "viewport" : { 
       "northeast" : { 
        "lat" : 40.81896778029149, 
        "lng" : -73.9518904197085 
       }, 
       "southwest" : { 
        "lat" : 40.81626981970849, 
        "lng" : -73.95458838029151 
       } 
      } 
     }, 
     "place_id" : "Eic1MDAgVyAxMzNyZCBTdCwgTmV3IFlvcmssIE5ZIDEwMDI3LCBVU0E", 
     "types" : [ "street_address" ] 
     } 
    ], 
    "status" : "OK" 
} 

，您可以篩選出neighborhood ，sublocality_level_1或postal_code類型，並獲取相關的long_name來搜索多邊形。
