Google Geocode API only USA结果

Question

我使用的是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

这个URL将返回全世界的结果，但是我如何将这些结果限制在美国呢？我查了一下，但什么也没找到。我讨厌编写过多的代码来确保没有任何美国地址，而实际上可能有一种方法可以添加到URL中并获得：

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

如果没有任何结果，这就是API返回的结果。容易多了。

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

也许当你尝试你在问题中提供的链接时，谷歌出现了一个小故障。我刚试过，它工作得很好：

{
   "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
            },
            "location_type" : "APPROXIMATE",
            "viewport" : {
               "northeast" : {

                  "lng" : -118.3867129
               },
               "southwest" : {
                  "lat" : 34.065094,
                  "lng" : -118.4423781
               }
            }
         },
         "types" : [ "postal_code" ]
      }
   ],
   "status" : "OK"
}
