I have created an API that I am now attempting to access through another application. Even though I am using Newtonsoft.JSON to both serialize and deserialize the JSON, I am encountering a conversion error, with the following InnerException:
{"Could not cast or convert from System.String to System.Collections.Generic.List`1[MidamAPI.Models.ManagerDTO]."}
The following is the snippet that throws the error (in RESTFactory):
public List<T> Execute<T>(String endPoint) where T : new() {
RestClient client = new RestClient(BASE_URL);
IRestRequest req = new RestRequest(endPoint);
req.AddHeader("Authorization", "Bearer " + this._token);
var response = client.Execute(req).Content;
List<T> responseData = JsonConvert.DeserializeObject<List<T>>(response);
return responseData;
}
which is called here:
{
RegisterViewModel vm = new RegisterViewModel();
RESTFactory factory = new RESTFactory((String)Session["bearer"]);
vm.availableManager = factory.Execute<ManagerDTO>("managers");
vm.availableProperties = factory.Execute<PropertyDTO>("locations");
vm.availableTrainers = factory.Execute<TrainerDTO>("trainers");
return View(vm);
}
The information is coming from the following API controller action (in a separate application):
[LocalFilter]
[RoutePrefix("managers")]
public class ManagersController : ApiController
{
UnitOfWork worker = new UnitOfWork();
[Route("")]
public string Get()
{
IEnumerable<ManagerDTO> dtoList = Mapper.Map<List<Manager>, List<ManagerDTO>>(worker.ManagerRepo.Get().ToList());
foreach (ManagerDTO dto in dtoList)
{
Manager manager = worker.ManagerRepo.GetByID(dto.ID);
dto.Stores = (Mapper.Map<IEnumerable<Property>, IEnumerable<PropertyDTO>>(manager.Properties)).ToList();
}
return JsonConvert.SerializeObject(dtoList);
}
The DTOs are the same in both applications:
{
public class ManagerDTO
{
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public List<PropertyDTO> Stores { get; set; }
}
public class PropertyDTO
{
public int ID;
public string ShortName { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
public string Phone { get; set; }
public string Lat { get; set; }
public string Long { get; set; }
public string GooglePlaceID { get; set; }
public string PropertyNumber { get; set; }
public int ManagerID { get; set; }
public int TrainerID { get; set; }
public string ManagerName { get; set; }
public string ManagerEmail { get; set; }
public string TrainerEmail { get; set; }
}
I tried using the json2csharp tool with the response, and everything seems fine to my eyes:
public class Store
{
public int ID { get; set; }
public string ShortName { get; set; }
public string Street { get; set; }
public string City { get; set; }
public string State { get; set; }
public string Zip { get; set; }
public string Phone { get; set; }
public string Lat { get; set; }
public string Long { get; set; }
public string GooglePlaceID { get; set; }
public string PropertyNumber { get; set; }
public int ManagerID { get; set; }
public int TrainerID { get; set; }
public string ManagerName { get; set; }
public string ManagerEmail { get; set; }
public object TrainerEmail { get; set; }
}
public class RootObject
{
public int ID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public List<Store> Stores { get; set; }
}
Any advice would be appreciated.
EDIT:
The RegisterViewModel class public class RegisterViewModel {
public RegistrationDTO regModel { get; set; }
public List<ManagerDTO> availableManager { get; set; }
public List<PropertyDTO> availableProperties { get; set; }
public List<TrainerDTO> availableTrainers { get; set; }
}
Make your controller Get() return type IHttpActionResult
and return Ok(dtoList);
