我正在使用 Google 为邮政编码查找提供的简单 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 并获取以下内容时，我不想编写更多代码以确保没有任何美国地址：

  {
  "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。

您可以使用组件过滤并使用country和postal_code组件

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

当您尝试在问题中提供的链接时，也许 Google 出现了故障。我刚试了一下，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" ]
            },
            {

                  "lng" : -118.4423781
               }
            },
            "location" : {

   ],
   "status" : "OK"
}
