仅限 Google Geocode API 美国结果

Question

我正在使用 Google 提供的用于邮政编码查找的简单 URL。

http://maps.googleapis.com/maps/api/geocode/json?address=90210&sensor=true

此 URL 将返回全世界的结果，但我如何将这些结果限制在美国？我查了一下，但找不到任何东西。当可能有办法添加到 URL 并获取：

  {
  "results" : [],
  "status" : "ZERO_RESULTS"
  }

如果根本没有结果，这就是 API 返回的内容。容易得多。

Answer 1

您可以使用component filtering 并使用country 和postal_code 组件

http://maps.googleapis.com/maps/api/geocode/json?sensor=true&components=country:US|postal_code:90210

Answer 2

当您尝试您在问题中提供的链接时，也许 Google 出现了故障。我刚刚试了一下，效果很好：

{
   "results" : [
      {
         "address_components" : [
            {
               "long_name" : "90210",
               "short_name" : "90210",
               "types" : [ "postal_code" ]
            },
            {
               "long_name" : "Beverly Hills",
               "short_name" : "Beverly Hills",
               "types" : [ "locality", "political" ]
            },
            {
               "long_name" : "Los Angeles County",
               "short_name" : "Los Angeles County",
               "types" : [ "administrative_area_level_2", "political" ]
            },
            {
               "long_name" : "California",
               "short_name" : "CA",
               "types" : [ "administrative_area_level_1", "political" ]
            },
            {
               "long_name" : "United States",
               "short_name" : "US",
               "types" : [ "country", "political" ]
            }
         ],
         "formatted_address" : "Beverly Hills, CA 90210, USA",
         "geometry" : {
            "bounds" : {
               "northeast" : {
                  "lat" : 34.1354771,
                  "lng" : -118.3867129
               },
               "southwest" : {
                  "lat" : 34.065094,
                  "lng" : -118.4423781
               }
            },
            "location" : {
               "lat" : 34.1030032,
               "lng" : -118.4104684
            },

            "viewport" : {

               },
               "southwest" : {
                  "lat" : 34.065094,
                  "lng" : -118.4423781
               }
            }
         },
         "types" : [ "postal_code" ]
      }
   ],
   "status" : "OK"
}
