[英]Json.NET and RESTSharp - Error Converting Value
I have created an API that I am now attempting to access through another application. 我创建了一个API,现在尝试通过另一个应用程序进行访问。 Even though I am using Newtonsoft.JSON to both serialize and deserialize the JSON, I am encountering a conversion error, with the following InnerException:
即使我使用Newtonsoft.JSON对JSON进行序列化和反序列化,也遇到了以下InnerException转换错误:
{"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): 以下是引发错误的代码段(在RESTFactory中):
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: 在这里称为:
{
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): 该信息来自以下API控制器操作(在单独的应用程序中):
[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: 两种应用中的DTO相同:
{
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: 我尝试将json2csharp工具与响应一起使用,一切似乎对我来说都很好:
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. 任何意见,将不胜感激。
EDIT: 编辑:
The RegisterViewModel class public class RegisterViewModel { RegisterViewModel类公共类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 使您的控制器的Get()返回类型为IHttpActionResult
and return Ok(dtoList); 并返回Ok(dtoList);
