谷歌 api 地理编码只能获取一些值

Question

我正在使用谷歌地理编码API。一切正常。但是，当我搜索 1 个位置时，我会收到许多信息。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:)

我收到这个：

现在我必须这样做：

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

我明白administrative_area_level_1.

有更好的吗？

Answer 1

地理编码 API 中的反向地理编码还允许指定要获取的结果类型。为了仅获取类型administrative_area_level_1的结果，请在请求中添加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

响应将仅包含行政区域级别 1 项，因此您可以检索行政区域的名称作为

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

或

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

我希望这有帮助！
