Google地理編碼-如何使用REST API從經緯度獲取參考或ID

Question

我已經為此努力了好幾天...我正在使用Node.js對Google Maps REST API進行http調用，我需要遍歷數據庫中位置的記錄，並使用lat，lng-找到給定分辨率的Google位置ID或參考-例如說“國家”或“ administrative_level_1” ...

我發現這兩個剩余呼叫最接近我需要的呼叫：

https://maps.googleapis.com/maps/api/geocode/json?
latlng=47.333333,13.333333
&sensor=false
&key=YOUR_API_KEY
&result_type=administrative_area_level_1 

此調用接受lat，lng和所需的分辨率，並返回准確的結果，但沒有id或引用...這是結果json：

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "Salzburg",
               "short_name" : "Sbg.",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "Austria",
               "short_name" : "AT",
               "types" : [ "country", "political" ]
            }
         ],
         "formatted_address" : "Salzburg, Austria",
         "geometry" : {
            "bounds" : {
               "northeast" : {
                  "lat" : 48.04121,
                  "lng" : 13.9965099
               },
               "southwest" : {
                  "lat" : 46.94347,
                  "lng" : 12.07669
               }
            },
            "location" : {
               "lat" : 47.80949,
               "lng" : 13.05501
            },
            "location_type" : "APPROXIMATE",
            "viewport" : {
               "northeast" : {
                  "lat" : 48.04121,
                  "lng" : 13.9965099
               },
               "southwest" : {
                  "lat" : 46.94347,
                  "lng" : 12.07669
               }
            }
         },
         "types" : [ "administrative_area_level_1", "political" ]
      }
   ],
   "status" : "OK"
}

到目前為止，我唯一的其他選擇是使用自動完成的REST API，如下所示：

https://maps.googleapis.com/maps/api/place/autocomplete/xml?
key=YOUR_API_KEY
&location=47.333333,13.333333
&sensor=false
&language=en
&types=(regions)
&input=Austria

這個問題在於，由於它是用於自動完成功能，因此需要傳遞“ input”參數，而不僅僅是lat，lng，這對我來說更好。 最好是因為我要處理的位置使用多種語言，並且為每條記錄指定其語言將是一場噩夢。

這是上一個調用的結果json：我需要對預測對象進行迭代，並以我正在尋找的分辨率找到了這些對象...

原始數據來自我們使用的地理名稱數據庫。 我們將在應用程序的所有部分中切換使用google maps API，因此我只需要使用lat，lng和resolution將它們轉換為google location ID ...名稱是我無法控制的，因為它們是給定的。 並以多種語言...

如果您能指出一個能夠做到這一點的REST API調用或對此事的一系列HTTP調用，我將不勝感激。

欣賞它。 半開

根據Google網站上的API選擇器 ，我建議使用以下API：

將地理位置的緯度/經度坐標轉換為地址（反向地理編碼）。
Google Places API （網絡服務）
