Google Geocode API仅限美国结果

提问于

我正在使用Google为邮政编码查询提供的简单网址 .

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

此URL将返回整个世界的结果，但如何将这些限制仅限于美国？我查了一下却找不到任何东西 . 我不想编写超过必要的代码，以确保在可能有一种方法添加到URL并获得以下内容时没有任何美国地址：

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

如果根本没有结果，这就是API返回的内容 . 更容易 .

    当您尝试在问题中提供的链接时，Google可能会出现故障 . 我刚尝试过，它工作正常：

    {
   "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" : {
                  "lat" : 34.1354771,
                  "lng" : -118.3867129
               },
               "southwest" : {
                  "lat" : 34.065094,
                  "lng" : -118.4423781
               }
            }
         },
         "types" : [ "postal_code" ]
      }
   ],
   "status" : "OK"
}
