google-maps - Google Directions API 公交返回总是 "ZERO_RESULTS"

我正在开发一个应用程序,该应用程序使用谷歌 API 来获取传输解决方案,以便在所需时间到达某个位置。

我调用 google API 的代码在“驾驶”和“步行”旅行模式下完美运行,但在“公交”和“骑自行车”的情况下,响应始终标记为“ZERO_RESULTS”状态,并且不计算任何路线。
根据谷歌文档,这意味着在必须计算解决方案的国家/地区不提供过境和骑自行车。
我尝试了几个国家,我总是得到相同的结果,我也尝试了概述中的谷歌示例(用于过境),但它不起作用。

我通过 HTTPS 请求传递的参数是:出发地、目的地、出行方式、到达时间。
我尝试的第一件事是更改arrival_time,以防该值涉及过去或太遥远的 future ,但它不起作用。

如果我没有通过“arrival_time”,则响应是完美的,但我不明白,因为在 Google 文档中,arrival_time 是 https 请求的一个可能参数,也适用于过境旅行模式。没有这个论点,这个请求对我的目标毫无用处。

奇怪的是,如果我通过“过境”(到达或离开时间),响应是这样的:

{
"available_travel_modes" : [ "DRIVING", "WALKING" ],
"geocoded_waypoints" : [
{
"geocoder_status" : "OK",
"place_id" : "ChIJu46S-ZZhLxMROG5lkwZ3D7k",
"types" : [ "locality", "political" ]
},
{
"geocoder_status" : "OK",
"place_id" : "ChIJ53USP0nBhkcRjQ50xhPN_zw",
"types" : [ "locality", "political" ]
}
],
"routes" : [],
"status" : "ZERO_RESULTS"
}

如果我通过“骑自行车”(所有其他参数不变):
{
"available_travel_modes" : [ "DRIVING", "WALKING", "TRANSIT" ],
"geocoded_waypoints" : [
{
"geocoder_status" : "OK",
"place_id" : "ChIJu46S-ZZhLxMROG5lkwZ3D7k",
"types" : [ "locality", "political" ]
},
{
"geocoder_status" : "OK",
"place_id" : "ChIJ53USP0nBhkcRjQ50xhPN_zw",
"types" : [ "locality", "political" ]
}
],
"routes" : [],
"status" : "ZERO_RESULTS"
}

所以在第二种情况下,API 说 TRANSIT 可用,这根本没有意义!

我使用的位置格式是地理坐标,以避免出现歧义。

希望我提供足够的信息以使您能够帮助我。

编辑:对不起,我认为我的帖子已经足够清楚了。
我使用 Google 路线 API: https://developers.google.com/maps/documentation/directions/

我的问题是“过境”和“骑自行车”作为旅行模式,不是代码问题,但问题出现在 https 响应级别,即使在我获得的概述中可以找到“过境”的谷歌示例“ZERO_RESULTS”响应。
这是示例的 URL:
https://maps.googleapis.com/maps/api/directions/json?origin=75+9th+Ave+New+York,+NY&destination=MetLife+Stadium+1+MetLife+Stadium+Dr+East+Rutherford,+NJ+07073&mode=transit&arrival_time=1391374800&key=YOUR_API_KEY

这是两个 URL,它让我得到我上面复制的两个响应:
过境:
https://maps.googleapis.com/maps/api/directions/json?origin=Rome&destination=Milan&mode=transit&arrival_time=1513162800000&key=++API_KEY++

和骑自行车:
https://maps.googleapis.com/maps/api/directions/json?origin=Rome&destination=Milan&mode=transit&arrival_time=1513162800000&key=++API_KEY++

在我用于起点和目的地地理坐标的代码中,如下所示:
https://maps.googleapis.com/maps/api/directions/json?origin=41.9027835,12.496365500000024&destination=45.4642035,9.189981999999986&mode=transit&arrival_time=1513162800000&key=++API_KEY++

唯一的区别是谷歌不识别地理编码的航点:
{
"available_travel_modes" : [ "DRIVING", "WALKING" ],
"geocoded_waypoints" : [ {}, {} ],
"routes" : [],
"status" : "ZERO_RESULTS"
}

如果我使用“驾驶”作为旅行模式,这行得通:
https://maps.googleapis.com/maps/api/directions/json?origin=41.9027835,12.496365500000024&destination=45.4642035,9.189981999999986&mode=driving&arrival_time=1513162800000&key=++API_KEY++

如果我在没有到达时间的情况下使用“过境”,它会起作用:

最佳答案

您请求中的问题是您作为 arrival_time 传递的值范围。请注意,此值必须以秒为单位:

arrival_time — Specifies the desired time of arrival for transit directions, in seconds since midnight, January 1, 1970 UTC. You can specify either departure_time or arrival_time, but not both. Note that arrival_time must be specified as an integer.



https://developers.google.com/maps/documentation/directions/intro#DirectionsRequests

您正在通过毫秒 1513162800000对应于 03/22/49920 @ 8:00am (UTC) ,正确值为 1513162800对应于 12/13/2017 @ 11:00am (UTC) .

请求应该是:
https://maps.googleapis.com/maps/api/directions/json?origin=41.9027835%2C12.496365500000024&destination=45.4642035%2C9.189981999999986&mode=transit&arrival_time=1513162800&key=YOUR_API_KEY
方向计算器中的相同请求:

https://directionsdebug.firebaseapp.com/?origin=41.9027835%2C12.496365500000024&destination=45.4642035%2C9.189981999999986&mode=transit&arrival_time=1513162800

我希望这有帮助!
