Lor*_*oni 5 google-maps google-directions-api travel-time
我正在开发一个应用程序，它使用谷歌 API 来获取交通解决方案，以便在所需的时间到达某个位置。
\n\n我调用 google API 的代码与“驾驶”和“步行”出行模式完美配合，但对于“公交”和“骑自行车”，响应始终标记为状态“ZERO_RESULTS”，并且不计算任何路线。\n这由google 文档，意味着在必须计算解决方案的国家/地区不提供公共交通和骑自行车服务。\n我尝试了多个国家/地区，但总是得到相同的结果，我还尝试了概述中的 Google 示例（针对公共交通）和它不起作用。
\n\n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。\n我尝试的第一件事是更改到达时间，以防该值指的是过去或太遥远的未来，但它不起作用。
\n\n如果我没有通过“arrival_time”，响应是完美的，但我不明白，因为在 Google 文档中很清楚，arrival_time 是 https 请求的一个可能参数，也适用于过境旅行模式。如果没有这个论点，这个请求对我的目标来说毫无用处。
\n\n奇怪的是，如果我通过“过境”（带有到达或出发时间），则响应是这样的：
\n\n{\n "available_travel_modes" : [ "DRIVING", "WALKING" ],\n "geocoded_waypoints" : [\n {\n "geocoder_status" : "OK",\n "place_id" : "ChIJu46S-ZZhLxMROG5lkwZ3D7k",\n "types" : [ "locality", "political" ]\n },\n {\n "geocoder_status" : "OK",\n "place_id" : "ChIJ53USP0nBhkcRjQ50xhPN_zw",\n "types" : [ "locality", "political" ]\n }\n ],\n "routes" : [],\n "status" : "ZERO_RESULTS"\n}\n如果我通过“骑自行车”（所有其他参数不变）：
\n\n{\n "available_travel_modes" : [ "DRIVING", "WALKING", "TRANSIT" ],\n "geocoded_waypoints" : [\n {\n "geocoder_status" : "OK",\n "place_id" : "ChIJu46S-ZZhLxMROG5lkwZ3D7k",\n "types" : [ "locality", "political" ]\n },\n {\n "geocoder_status" : "OK",\n "place_id" : "ChIJ53USP0nBhkcRjQ50xhPN_zw",\n "types" : [ "locality", "political" ]\n }\n ],\n "routes" : [],\n "status" : "ZERO_RESULTS"\n}\n所以在第二种情况下，API 说 TRANSIT 可用，但这根本没有意义！
\n\n我使用的位置格式是地理坐标，以避免出现歧义。
\n\n希望我提供足够的信息以使您能够帮助我。
\n\n编辑：抱歉，我以为我的帖子已经足够清楚了。\n我使用 Google Directions API： https: //developers.google.com/maps/documentation/directions/
\n\n我的问题是“过境”和“骑自行车”作为出行模式，不是代码问题，但问题出现在 https 响应级别，即使使用“过境”的谷歌示例（可以在我获得的概述中找到） “ZERO_RESULTS”响应。\n这是示例的 URL：
\n\nhttps://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\n下面是两个 URL，它们让我得到了上面复制的两个响应：\n与过境：
\n\nhttps://maps.googleapis.com/maps/api/directions/json?origin=Rome&destination=Milan&mode=transit&arrival_time=1513162800000&key=++API_KEY++\n以及骑自行车：
\n\nhttps://maps.googleapis.com/maps/api/directions/json?origin=Rome&destination=Milan&mode=transit&arrival_time=1513162800000&key=++API_KEY++\n在我用于起点和目的地地理坐标的代码中，如下所示：
\n\nhttps://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++\n唯一的区别是谷歌不识别地理编码的航点：
\n\n{\n "available_travel_modes" : [ "DRIVING", "WALKING" ],\n "geocoded_waypoints" : [ {}, {} ],\n "routes" : [],\n "status" : "ZERO_RESULTS"\n}\n如果我使用“驾驶”作为旅行模式，这有效：

您请求中的问题是您作为arrival_time。请注意，该值必须以秒为单位：
\n\n\n到达时间\xe2\x80\x94 指定公交路线所需的到达时间（以秒为单位）。您可以指定出发时间或到达时间，但不能同时指定两者。请注意，arrival_time 必须指定为整数。
