android - 如何通过来自 google maps api 的流量获取导航持续时间？

Question

我想通过 http 请求从 google maps api 获取导航持续时间: https://maps.googleapis.com/maps/api/directions/json?origin=src&destination=destination

但我得到了没有流量的持续时间。如何获得流量持续时间？

Answer 1

您现在无需高级帐户即可获得 duration_in_traffic(只需来自 the developer console 的标准 API key 并启用“Google Maps Directions API”)。在您的浏览器中使用

进行验证

https://maps.googleapis.com/maps/api/directions/json?origin=Brooklyn&destination=Queens&departure_time=now&key=YOUR_KEY_HERE

看来 javascript 客户端使用了另一个尚未返回 duration_in_traffic 的端点。

请求必须满足以下条件，更新于 the docs :

• The request includes a departure_time parameter.
• The request includes a valid API key, or a valid Google Maps APIs Premium Plan client ID and signature.
• Traffic conditions are available for the requested route.
• The request does not include stopover waypoints.
• The request is specifically for driving directions— the mode parameter is set to driving.
