그래서 저는 Google Maps API를 사용하여 두 도시 사이의 거리를 얻으려고합니다. Json 형식을 보려면 여기로 이동하십시오. https://developers.google.com/maps/documentation/directions/start
따라서 My Class 객체는 다음과 같이 보입니다.
public class GeocodedWaypoint
{
public string geocoder_status { get; set; }
public string place_id { get; set; }
public List<string> types { get; set; }
public bool? partial_match { get; set; }
}
public class Northeast
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Southwest
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Bounds
{
public Northeast northeast { get; set; }
public Southwest southwest { get; set; }
}
public class Distance
{
public string text { get; set; }
public int value { get; set; }
}
public class Duration
{
public string text { get; set; }
public int value { get; set; }
}
public class EndLocation
{
public double lat { get; set; }
public double lng { get; set; }
}
public class StartLocation
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Distance2
{
public string text { get; set; }
public int value { get; set; }
}
public class Duration2
{
public string text { get; set; }
public int value { get; set; }
}
public class EndLocation2
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Polyline
{
public string points { get; set; }
}
public class StartLocation2
{
public double lat { get; set; }
public double lng { get; set; }
}
public class Step
{
public Distance2 distance { get; set; }
public Duration2 duration { get; set; }
public EndLocation2 end_location { get; set; }
public string html_instructions { get; set; }
public Polyline polyline { get; set; }
public StartLocation2 start_location { get; set; }
public string travel_mode { get; set; }
public string maneuver { get; set; }
}
public class Leg
{
public Distance distance { get; set; }
public Duration duration { get; set; }
public string end_address { get; set; }
public EndLocation end_location { get; set; }
public string start_address { get; set; }
public StartLocation start_location { get; set; }
public List<Step> steps { get; set; }
public List<object> traffic_speed_entry { get; set; }
public List<object> via_waypoint { get; set; }
}
public class OverviewPolyline
{
public string points { get; set; }
}
public class Route
{
public Bounds bounds { get; set; }
public string copyrights { get; set; }
public List<Leg> legs { get; set; }
public OverviewPolyline overview_polyline { get; set; }
public string summary { get; set; }
public List<object> warnings { get; set; }
public List<object> waypoint_order { get; set; }
}
public class RootObject
{
public List<GeocodedWaypoint> geocoded_waypoints { get; set; }
public List<Route> routes { get; set; }
public string status { get; set; }
}
그리고 저는 이것으로 다리 오브젝트를 얻고 싶습니다.
static async Task<Leg> GetLegAsync(string path)
{
Leg leg = null;
HttpResponseMessage response = await client.GetAsync(path);
if (response.IsSuccessStatusCode)
{
var json = await response.Content.ReadAsStringAsync();
leg = JsonConvert.DeserializeObject<Leg>(json);
}
return leg;
}
문제는 이것을 통해 다리 객체에 액세스 할 때 제대로 역 직렬화되지 않는다는 것입니다. 어리석은 간단한 경우 미안하지만 HTTP 클라이언트와 이와 같은 것들을 실제로 엉망으로 만들지 않았습니다. 나는 C #에 꽤 능숙하지만 기능성에 대한 과거의 많은 연구를하지 않았고 이것의 일부에 들어갔다.
편집 : 이것이 도움이된다면
static async Task RunAsync(string pos1,string pos2)
{
string apiKey = "MUST_KEEP_HIDDEN!";
client.BaseAddress = new Uri("https://maps.googleapis.com/maps/api/directions/json?origin="+pos1+"&destination="+pos2+"&key=" + apiKey);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//Console.ReadLine();
Leg leg = await GetLegAsync("https://maps.googleapis.com/maps/api/directions/json?origin=" + pos1 + "&destination=" + pos2 + "4&key=" + apiKey);
showinfo(leg);
}
미리 감사드립니다
quicktype.io를 사용 하여이 코드를 생성했습니다 .
jsonString Google Maps API의 API 응답입니다.
이 예에서는 다음 API를 사용했습니다.

// using QuickType;
//
// var data = GettingStarted.FromJson(jsonString);
