按 Google 方向 api 创建路线时出现问题

Question

这是我正在使用的 URL :

https://maps.googleapis.com/maps/api/directions/json?origin=28.6139,77.2090&destination=25.992003,-80.117802&key=API KEY

当我在浏览器中点击此 URL 时，我收到以下响应：

{
   "geocoded_waypoints" : [ {}, {} ],
   "routes" : [],
   "status" : "ZERO_RESULTS"
}

源位置是德里，目标位置是 3555 N Ocean Dr, Hollywood, FL 33019, USA。如果我将目标位置更改为任何其他位置，那么我将获得地理编码 waypoints 的值，但为什么不获取上述值？

非常感谢您的帮助。

Answer 1

我认为您的错误是由 API 方向的出行方式限制引起的。

出行方式

When you calculate directions, you may specify the transportation mode to use. By default, directions are calculated as driving directions. The following travel modes are supported:

driving (default) indicates standard driving directions using the road network.

walking requests walking directions via pedestrian paths & sidewalks (where available).

bicycling requests bicycling directions via bicycle paths & preferred streets (where available).

transit requests directions via public transit routes (where available). If you set the mode to transit, you can optionally specify either a departure_time or an arrival_time. If neither time is specified, the departure_time defaults to now (that is, the departure time defaults to the current time). You can also optionally include a transit_mode and/or a transit_routing_preference.

Google 地图应用程序（浏览器）中的示例路线

https://www.google.com.ph/maps/dir/28.6139,77.209/'25.992003,-80.117802'/@22.2476068,-39.0397189,4z/data=!3m1!4b1!4m6!4m5!1m0!1m3!2m2!1d-80.117802!2d25.992003

如果您在浏览器中检查link，出行模式是飞行，在API方向不可用。

希望这对您有所帮助。
