У меня есть метод ниже,
[IdentityBasicAuthentication]
[Authorize]
public HttpResponseMessage PostRouteInformation(RouteCreateInformationMM routeCreateInformation)
{
try
{
return Request.CreateResponse(HttpStatusCode.OK, _routeMobileManager.RetreiveCreateRouteInformation(routeCreateInformation));
}
catch (BusinessException bex)
{
return Request.CreateErrorResponse(HttpStatusCode.BadRequest, bex.Message);
}
}
Что он делает, он создает URL с заданными значениями широты и логитивности и публикует его в Googleapis.После этого он захватывает возвращенную строку JSON и заполняет необходимые поля из этой возвращенной строки JSON.
Ниже приведен метод, о котором я говорю выше,
public string GetRouteInformation(RouteCreateInformationMM routeCreateInformation, List<MapOriginsMM> poiCoordinates)
{
string url = GetRouteUrl(routeCreateInformation, poiCoordinates);
WebClient webClient = new WebClient();
var content = webClient.DownloadString(url);
return content;
}
А ниже приведен методтот, который создает строку URL,
private string GetRouteUrl(RouteCreateInformationMM routeCreateInformation, List<MapOriginsMM> poiCoordinates)
{
StringBuilder sb = new StringBuilder();
sb.Append(ConstantValue.StaticMap.RouteInformationUrl);
sb.Append("?mode=");
sb.Append(routeCreateInformation.Mode);
if (routeCreateInformation.Latitude != 0 && routeCreateInformation.Longitude != 0)
{
sb.Append("&origin=");
sb.Append(routeCreateInformation.Latitude.ToString(System.Globalization.CultureInfo.InvariantCulture) + "," + routeCreateInformation.Longitude.ToString(System.Globalization.CultureInfo.InvariantCulture));
foreach (var origins in poiCoordinates)
{
if (origins == poiCoordinates.Last())
{
sb.Append("&destination=");
sb.Append(origins.Latitude.ToString(System.Globalization.CultureInfo.InvariantCulture) + "," + origins.Longitude.ToString(System.Globalization.CultureInfo.InvariantCulture));
}
}
}
else
{
foreach (var origins in poiCoordinates)
{
if (origins == poiCoordinates.First())
{
sb.Append("&origin=");
sb.Append(origins.Latitude.ToString(System.Globalization.CultureInfo.InvariantCulture) + "," + origins.Longitude.ToString(System.Globalization.CultureInfo.InvariantCulture));
}
else if (origins == poiCoordinates.Last())
{
sb.Append("&destination=");
sb.Append(origins.Latitude.ToString(System.Globalization.CultureInfo.InvariantCulture) + "," + origins.Longitude.ToString(System.Globalization.CultureInfo.InvariantCulture));
}
}
}
foreach (var origins in poiCoordinates)
{
if (origins != poiCoordinates.First() && origins != poiCoordinates.Last())
{
sb.Append("&waypoints=optimize:true|" + origins.Latitude.ToString(System.Globalization.CultureInfo.InvariantCulture) + "," + origins.Longitude.ToString(System.Globalization.CultureInfo.InvariantCulture));
}
}
sb.Append($"&key={ConstantValue.ApiKey}");
return sb.ToString();
}
В конце URL выглядит примерно так (кстати, я намеренно составил значение ключа для вопроса):
https://maps.googleapis.com/maps/api/directions/json?mode=walking&origin=41.0923621,29.0947456&destination=41.0943909,29.0966665&key=AOzaSyApOqYW39erJ7zWsqXnV-0NLfltkHu0KfB

Все в порядке, пока я не опубликую свой проект и не помещу его в наш тестовый домен.
Я мог бы успешно заполнить свою модель возврата, ЕСЛИ я работаюна моем локальном хосте
[{"Legs":[{"Steps":[{"EndLocation":[{"Lat":41.0917854,"Lng":29.0938952},{"Lat":41.0927256,"Lng":29.0943774},{"Lat":41.0931956,"Lng":29.094848},{"Lat":41.094488299999988,"Lng":29.0952805},{"Lat":41.0945246,"Lng":29.0954362},{"Lat":41.0945706,"Lng":29.0955857},{"Lat":41.094365499999988,"Lng":29.0967187}]}]}]}]
Но, если я отправляю запрос в живой проект, он возвращает мне нулевую модель,
[{"Legs":[{"Steps":[{"EndLocation":[]}]}]}]
Я понятия не имею, почему.Может ли это быть что-то с родственными Googleapis?Или, может быть, WebClient не работает должным образом на сервере.
Заранее спасибо!
