我正在使用google geocoding api。一切正常。但是，当我搜索1个位置时，会收到很多信息。例如，我只需要administrative_area_level_1。
我使用的网址：
https://maps.googleapis.com/maps/api/geocode/json?latlng=12.1224221,-68.8824233&sensor=false&key=mykey:)
我收到此：

现在我必须这样做：
json_decode($response->getBody())->results[0]->address_components[4]->long_name;
我得到了administrative_area_level_1。
有更好的地方吗？
Reverse geocoding也允许指定您想要获取的结果类型。为了仅获取类型为Administrative_area_level_1的结果，请在您的请求中添加result_type参数
https://maps.googleapis.com/maps/api/geocode/json?latlng=12.1224221%2C-68.8824233&result_type=administrative_area_level_1&key=YOUR_API_KEY
响应将仅包含管理区域级别1的项目，因此您可以将管理区域的名称检索为：
json_decode($response->getBody())->results[0]->formatted_address
或
json_decode($response->getBody())->results[0]->address_components[0]->long_name
我希望这会有所帮助！
