无法在Google地图中建立自行车路线 [英] Unable to build a bicycle route in Google maps

问题描述

我很好奇！当我使用 origin1 和 destinationA 无效

i am wonder ! when i using origin1 and destinationA not working

status ="ZERO_RESULTS";

status = "ZERO_RESULTS";

但是如果使用 origin2 和 destinationB ，它工作正常，我错过了什么吗?

but if used origin2 and destinationB it is working perfectly do i missed anything

var origin = "55.930385, -3.118425"
var destination = "50.087692, 14.421150"

  override func viewDidLoad() {
    super.viewDidLoad()
    durationDestance(origin: origin, destination: destination, mode:"bicycling")
  }
 func durationDestance(origin: String, destination: String, mode:String) {

            var urlString : String = "https://maps.googleapis.com/maps/api/distancematrix/json?origins=\(origin)&destinations=\(destination)&mode=\(mode)&key=AIzaSyAVOt9LLagNGSOI8O0ri1Sbahcl_q5AFYc";

            urlString = urlString.addingPercentEncoding(withAllowedCharacters: .urlFragmentAllowed)!
            let session = URLSession.shared
            let url = URL(string:urlString)!
            session.dataTask(with: url) { (data: Data?, response: URLResponse?, erorr: Error?) -> Void in

                print("url: \(urlString)")
                if let responseData = data {
                    do{
                        let json = try JSONSerialization.jsonObject(with: responseData, options: JSONSerialization.ReadingOptions.allowFragments);
                        print(json);
                    }
                    catch{
                        print("do not serialization :)");
                    }
                }
                }.resume();
        }

推荐答案

因为这些点之间没有循环路径. 尝试选择自行车:

Because there is no cycle path between these points. Try to select bicycle: google maps

我试图乘自行车和汽车上路.建立自行车路线是不可能的，并且存在自驾路线

I tried to make a route by bike and car. It is impossible to build a bicycle route, and the route by car exists
