Google Maps Geocode doesn't return country

问题

I need a reliable method to get the city, state and country place_id from latitude and longitude.

I'm trying by using Google Maps geocode, but the problem is that some coordinates don't return the administrative_level_1 (state) or the country.

Take this GET request for instance:

https://maps.googleapis.com/maps/api/geocode/json?latlng=-25.4364413,-49.2839333&result_type=country&key=YOUR_API_KEY

It returns:

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

Did you know a way to get this results?

I've already added a link to this question in the bug. You can also check workarounds suggested by users in bug comments.

For example, there is following suggestion

I found a workaround: if I do not get a country back, I will do a second reverse geocoding with the coordinates of the highest result I got. Most of the times these coordinates will be in an area, where I can get the country.

This is not ideal, but it works for the cases I found.
