Google Maps API - “道路”距离2点 [英] Google Maps API - "road" distance between 2 points

问题描述

我有一个网站，根据存储在数据库中的纬度和经度坐标，显示每个项目的附近位置。

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

问题是这样计算距离是空中线路距离，与实际驾驶距离有很大差异。

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

Google地图目前只有一个JavaScript API用于驱动路线，我需要它作为Web服务API直接从服务器进行调用。

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.

有没有可能做到这一点？

Is there any possibility to do this?

推荐答案

Google Maps API有一个HTTP为地理编码服务，但不适用于路线。您只能通过Javascript API访问该功能。你可以破解它，但它会打破谷歌的ToS。

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.
