Google api 地理编码只得到一些值

Question

我正在使用 google geocoding api。一切正常。但是，当我搜索 1 个位置时，我会收到很多信息。例如，我只需要 administrative_area_level_1。

我使用的

Url：

https://maps.googleapis.com/maps/api/geocode/json?latlng=12.1224221,-68.8824233&sensor=false&key=mykey:)

我收到这个：

现在我必须这样做：

json_decode($response->getBody())->results[0]->address_components[4]->long_name;

然后我得到 administrative_area_level_1。

还有更好的吗？

Geocoding API 中的

Reverse geocoding 还允许指定您想要获得的结果类型。为了仅获得 administrative_area_level_1 类型的结果，请在您的请求中添加一个 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

响应将仅包含行政区域级别 1 项，因此您可以检索行政区域名称作为

json_decode($response->getBody())->results[0]->formatted_address

或

json_decode($response->getBody())->results[0]->address_components[0]->long_name

希望对您有所帮助！
