我想从http请求谷歌地图API的导航时间：

I want to get the navigation duration from google maps api with http request: https://maps.googleapis.com/maps/api/directions/json?origin=src&destination=destination

但我得到的时间没有交通。
我怎样才能获得持续的交通？

推荐答案

从谷歌地图API，它指出：

From the Google Directions API, it states that:

duration_in_traffic indicates the total duration of this leg, taking into account current traffic conditions. The duration in traffic will only be returned if all of the following are true:

1.The directions request includes a departure_time parameter set to a value within a few minutes of the current time.
2.The request includes a valid Google Maps API for Work client and signature parameter.
3.Traffic conditions are available for the requested route.
4.The directions request does not include stopover waypoints.

所以，你需要满足以交通时间检索上述所有要求。

So you need to meet all the above requirements in order to retrieve duration with traffic.

有关更多信息，请访问的谷歌的腿部分地图API文档。

For more information, you can visit the Leg section of the Google Directions API documentation.
