Google Maps API - “road” distance between 2 points

问题:

I have a website where "near locations" are shown for each item, based on the latitude and longitude coordinates stored in a database.

Problem is that this calculated distance is the air-line distance, which differs a lot ferom the actual driving distance.

Google Maps does only have a JavaScript API for driving directions by now, I need it as a web service API to make calls directly from the server.

Is there any possibility to do this?

回答1:

The Google Maps API has a HTTP service for geocoding, but not for directions. You can only access that functionality through the Javascript API. You could hack it, but it would break Google's ToS.
