推荐答案

您可以做一个使用谷歌地理codeR API的

You can make a use of the Google Geocoder API

所有你需要做的是让合适的查询，例如在请求到谷歌地理codeR提供给用户的经度和纬度的格式（在URL）的位置，然后解析JSON / XML响应。你可以看到，在提供有例子是JSON字符串，它标志着国家：

All you need to do is to make appropriate query, e.g in the request to the Google Geocoder providing the user's location in Latitude and Longitude format (in the url), and then parse the JSON/XML response. You can see that in the example that is provided there is JSON string that signifies the country:

{
  "status": "OK",
  "results": [ {
    "types": [ "street_address" ],
    "formatted_address": "1600 Amphitheatre Pkwy, Mountain View, CA 94043, USA",
    "address_components": [ {
      "long_name": "1600",
      "short_name": "1600",
      "types": [ "street_number" ]
    }, {
      "long_name": "Amphitheatre Pkwy",
      "short_name": "Amphitheatre Pkwy",
      "types": [ "route" ]
    }, {
      "long_name": "Mountain View",
      "short_name": "Mountain View",
      "types": [ "locality", "political" ]
    }, {
      "long_name": "California",
      "short_name": "CA",
      "types": [ "administrative_area_level_1", "political" ]
    }, {
      "long_name": "United States",    // <----- HERE IS THE COUNTRY NAME.
      "short_name": "US",
      "types": [ "country", "political" ]
    }, {
      "long_name": "94043",
      "short_name": "94043",
      "types": [ "postal_code" ]
    } ],
    "geometry": {
      "location": {
        "lat": 37.4219720,
        "lng": -122.0841430
      },
      "location_type": "ROOFTOP",
      "viewport": {
        "southwest": {
          "lat": 37.4188244,
          "lng": -122.0872906
        },
        "northeast": {
          "lat": 37.4251196,
          "lng": -122.0809954
        }
      }
    }
  } ]
}
