Studying WCF RESTful, host in a Console,
my steps:
create sample models
create contract of service
create service
host this service in a console.
run this host, looks ok.
create a winform, use service address via json post to service host.
i hope it would work, but return http 400.
I tried on WCF(not REST) Console-hosted, WebAPI, steps all ok.
finally, stackoverflow.com
please help
Models
[Serializable]
public abstract class Building
{
public Manufacturer Manufacturer { get; set; }
}
[Serializable]
public class Manufacturer
{
public string Name { get; set; }
public string Telephone { get; set; }
}
[Serializable]
public class Furniture : Building
{
public string Name { get; set; }
}
[Serializable]
public class Reception
{
public int Floor { get; set; }
public int Number { get; set; }
}
[Serializable]
public class Room : Building
{
public string Number { get; set; }
public List<Furniture> Furnitures { get; set; }
}
[Serializable]
public class Hotel : Building
{
public Guid Guid { get; set; }
public List<Reception> Receptions { get; set; }
public List<Room> Rooms { get; set; }
public string Name { get; set; }
public string Address { get; set; }
}
Contract
[ServiceContract]
public interface IHotel
{
// Create objct Hotel
[OperationContract]
[WebInvoke(UriTemplate = "", Method = "POST", RequestFormat= WebMessageFormat.Json, ResponseFormat=WebMessageFormat.Json)]
bool Create(Hotel hotel);
}
Service
public class HotelService : I Hotel
{
public bool Build(Models.Hotel hotel)
{
if (hotel == null)
return false;
// codes here is object hotel(EF) creation, test OK
return true;
}
}
Host(Console)
WebServiceHost serviceHost = new WebServiceHost(typeof(Demo.Services.HotelService), new Uri("http://192.168.1.101/HotelService"));
ServiceEndpoint endpoint = serviceHost.AddServiceEndpoint(typeof(Demo.Contracts.IHotel), new WebHttpBinding(), "");
ServiceDebugBehavior sdb = serviceHost.Description.Behaviors.Find<ServiceDebugBehavior>();
sdb.HttpHelpPageEnabled = false;
Console.WriteLine("Starting Service...");
// start service
serviceHost.Open();
Console.WriteLine("Started, press RETURN to exit.");
Console.ReadLine();
serviceHost.Close();
Client(Winform)
Caller
public bool BuildHotel(string json)
{
WebRequest request = HttpWebRequest.Create("http://192.168.1.101/HotelService");
request.ContentType = "application/json";
byte[] data = Encoding.UTF8.GetBytes(json);
request.ContentLength = data.Length;
Stream requestStream = request.GetRequestStream();
requestStream.Write(data, 0, data.Length);
requestStream.Close();
WebResponse response = request.GetResponse(); // 400 throwed here
Stream responseStream = response.GetResponseStream();
StreamReader responseStreamReader = new StreamReader(responseStream);
string result = responseStreamReader.ReadToEnd();
return true;
}
Json String for 'bool BuildHotel(string)' upon
{
"Guid":"ea59c011-d656-4870-b29b-30a44e668560",
"Receptions":[
{"Floor":1,"Number":1},
{"Floor":2,"Number":2}
],
"Rooms":[
{
"Number":"c",
"Furnitures":[
{"Name":"1","Manufacturer":{"Name":"1","Telephone":"1"}},
{"Name":"2","Manufacturer":{"Name":"2","Telephone":"2"}}
],
"Manufacturer":{"Name":"c","Telephone":"c"}
}
],
"Name":"x",
"Address":"x",
"Manufacturer":{"Name":"x","Telephone":"x"}
}
it expects such kind of JSON:
{"k_BackingField":{"k_BackingField":"4","k_BackingField":"4"},"k_BackingField":"x","k_BackingField":"ea59c011-d656-4870-b29b-30a44e668560","k_BackingField":"x","k_BackingField":[{"k_BackingField":1,"k_BackingField":1},{"k_BackingField":2,"k_BackingField":2}],"k_BackingField":[{"k_BackingField":{"k_BackingField":"3","k_BackingField":"3"},"k_BackingField":[{"k_BackingField":{"k_BackingField":"1","k_BackingField":"1"},"k_BackingField":"1"},{"k_BackingField":{"k_BackingField":"2","k_BackingField":"2"},"k_BackingField":"2"}],"k__BackingField":null}]}
To change it you can mark all your data contracts with DataContract and DataMember attribute:
[DataContract]
public abstract class Building
{
[DataMember]
public Manufacturer Manufacturer { get; set; }
}
In this case it will understand json as you have given us in the question and will process it successfully.

I am working on a new ASP.NET Core 3.1.1 API with Microsoft.AspNetCore.OData v 7.3.0, AutoMapper v9.0.0 and Microsoft.AspNetCore.Mvc.NewtonsoftJson v3.1.1
I am getting the following error when I make a POST to the Accounts endpoint using Postman v7.18.0;
AutoMapper.AutoMapperMappingException: Missing type map configuration or unsupported mapping.
I have reviewed the similar questions list when creating this question but was unable to find a solution.
In reviewing google searches for AutoMapper OData Enums all I could find were the recommendation to decorate my dto class with...
[AutoMap(typeof(Account))]
... and to decorate my dto enum properties with ...
[JsonConverter(typeof(StringEnumConverter))]
However, I still get the error. I found references to using an AutoMapperProfile class with a mapper defined as
CreateMap<Account, AccountModel>().ReverseMap();
But it appears that AutoMapper v9.0.0 no longer has a CreateMap method. My understanding was that adding the [AutoMap(typeof(Account))] to the dto class had the same effect as creating the map in the profile class.
I feel like I am going in circles at this point here so I though I would reach out to the SO community. I am sure it is something simple, I am just not seeing it.
Here is my POST request body from Postman;
{
"#odata.context": "https://localhost:44367/v1/$metadata#Accounts",
"AccountName": "Test Provider",
"AccountType": "Provider",
"IsTaxExempt": false,
"Status": "Active"
}
Here is my AccountsController Post method;
[ODataRoute]
[Produces("application/json;odata.metadata=minimal")]
[ProducesResponseType(typeof(AccountModel), Status201Created)]
[ProducesResponseType(Status400BadRequest)]
public async Task<IActionResult> Post([FromBody] AccountModel record)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
record.Id = new Guid();
var entity = _mapper.Map<Account>(record);
_context.Add(entity);
await _context.SaveChangesAsync();
var createdRecord = _mapper.Map<AccountModel>(entity);
return Created(createdRecord);
}
Here is my Account entity class;
public class Account : EntityBase
{
[Required]
[Column(TypeName = "nvarchar(50)")]
[MaxLength(50)]
public string AccountName { get; set; }
public AccountTypes AccountType { get; set; }
public bool IsTaxExempt { get; set; }
}
Here is the EntityBase class;
public class EntityBase
{
[Required]
public Guid Id { get; set; }
public DateTimeOffset? DateTimeCreated { get; set; } = DateTime.UtcNow;
public DateTimeOffset? DateTimeLastModified { get; set; }
[JsonConverter(typeof(StringEnumConverter))]
public StatusTypes Status { get; set; }
public bool DeleteFlag { get; set; }
}
Here is my Account DTO class;
[Filter, Count, Expand, OrderBy, Page, Select]
[AutoMap(typeof(Account))]
public class AccountModel : BaseModel
{
[Required]
[MaxLength(50)]
public string AccountName { get; set; }
[JsonConverter(typeof(StringEnumConverter))]
public AccountTypes AccountType { get; set; }
public bool IsTaxExempt { get; set; }
}
Here is my BaseModel class;
[Select, Filter]
public class BaseModel
{
public Guid Id { get; set; }
public DateTimeOffset DateTimeCreated { get; set; } = DateTime.UtcNow;
public DateTimeOffset DateTimeLastModified { get; set; }
[JsonConverter(typeof(StringEnumConverter))]
public StatusTypes Status { get; set; }
public bool DeleteFlag { get; set; }
}
And here are my Enums for AccountTypes and StatusTypes
public enum AccountTypes
{
Customer = 0,
Reseller = 1,
Provider = 2,
}
public enum StatusTypes
{
Active = 0,
Inactive = 1,
}
Any ideas?
It turns out that I needed to create an instance of an AutoMapper MapperConfiguration and assign it to the mapper.
I ended up putting in in the constructor of the Controller, for example;
public AccountsController(CdContext context, IMapper mapper)
{
_context = context ?? throw new ArgumentNullException(nameof(context));
_mapper = mapper ?? throw new ArgumentNullException(nameof(mapper));
var config = new MapperConfiguration(cfg => cfg.CreateMap<Account, AccountModel>().ReverseMap());
_mapper = new Mapper(config);
}
After I did this, everything worked as expected.
Here is a link to AutoMappers docs on the subject.
I have defined the data contract as follows:
[DataContract]
public class TestResult
{
[DataMember]
public string[] NegResponses { get; set; }
[DataMember]
public bool Pass { get; set; }
[DataMember]
public string Request { get; set; }
[DataMember]
public string Response { get; set; }
}
Is it possible to return a list of the above type in the operation contract as follows:
[OperationContract]
[FaultContract(typeof(TestFault))]
List<TestResult> Tester(string nodeCaption);
And what else I have to look into to return a list of a type that has been defined ?
By the way I guess I am not using svcutil and instead using channel factory as follows:
private static readonly ITestService TestClient;
// initialize a channel factory
var channelFactory = new ChannelFactory<ITestService>(new NetTcpBinding(SecurityMode.None), endPoint);
// Create a channel
TestClient = channelFactory.CreateChannel();
The client-side and the server-side should share the same service contract and data contract. This is fundamental that we could consume the service on the client-side.
Here is an example, wish it is useful to you.
Server-side.
class Program
{
static void Main(string[] args)
{
Uri uri = new Uri("http://localhost:21011");
BasicHttpBinding binding = new BasicHttpBinding();
using (ServiceHost sh = new ServiceHost(typeof(MyService), uri))
{
sh.AddServiceEndpoint(typeof(IService), binding, "");
ServiceMetadataBehavior smb;
smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (smb == null)
{
smb = new ServiceMetadataBehavior()
{
HttpGetEnabled=true
};
sh.Description.Behaviors.Add(smb);
}
Binding mexbinding = MetadataExchangeBindings.CreateMexHttpBinding();
sh.AddServiceEndpoint(typeof(IMetadataExchange), mexbinding, "mex");
sh.Opened += delegate
{
Console.WriteLine("Service is ready");
};
sh.Closed += delegate
{
Console.WriteLine("Service is clsoed");
};
sh.Open();
Console.ReadLine();
//pause
sh.Close();
Console.ReadLine();
}
}
}
[ServiceContract]
public interface IService
{
[OperationContract]
List<Product> SayHello();
}
public class MyService : IService
{
public List<Product> SayHello()
{
return new List<Product>()
{
new Product()
{
ID=1,
Name="Apple"
},
new Product()
{
ID=2,
Name="Pear"
}
};
}
}
[DataContract(Namespace = "MyNamespace")]
public class Product
{
[DataMember]
public int ID { get; set; }
[DataMember]
public string Name { get; set; }
}
Client-side (Console application,we call the service with ChannelFactory).
class Program
{
static void Main(string[] args)
{
BasicHttpBinding binding = new BasicHttpBinding();
Uri uri = new Uri("http://10.157.13.69:21011");
ChannelFactory<IService> factory = new ChannelFactory<IService>(binding, new EndpointAddress(uri));
IService service = factory.CreateChannel();
try
{
var result = service.SayHello();
foreach (var item in result)
{
Console.WriteLine($"ID:{item.ID}\n,Name:{item.Name}");
}
}
catch (Exception)
{
throw;
}
}
}
[ServiceContract]
public interface IService
{
[OperationContract]
List<Product> SayHello();
}
[DataContract(Namespace = "MyNamespace")]
public class Product
{
[DataMember]
public int ID { get; set; }
[DataMember]
public string Name { get; set; }
}
Data Contract should be decorated with Namespace property, this will guarantee that the serialization and deserialization process properly). Actually, the service contract also needs a namespace to represent the practical method name, which will be used to addressing the method on the server-side. but there is a default value in the namespace.

I am not able to pass List using WCF with wsHttpBinging. List is a property of FilterResponse class.
Getting the following error.
-Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

Your property in the DataContract is missing a DataMember attribute:
[DataMember]
public List<FilterData> FilterData { get; set; }
I am trying to call a 3rd party web service
Their REST API uses the following URL style.
http://www.VoiceBase.com/services?version=1.0&apikey=your-apikey&password=secret&action=list&status=processing
All of their service calls go to the same /services
How do I create a class so the following would work?
var client = new JsonServiceClient("http://www.voicebase.com");
var response = client.Get<ResponseVoiceBaseListClass>(new VoiceBaseListClass());
Additional classes I have created but I am not quite there yet
public class VoiceBaseBaseClass
{
public string version { get; set; }
public string apikey { get; set; }
public string password { get; set; }
public VoiceBaseBaseClass()
{
this.version = "1.0";
this.apikey = "API";
this.password = "password";
}
}
public class VoiceBaseListClass : VoiceBaseBaseClass, IReturn<ResponseVoiceBaseListClass>
{
public string action { get; set; }
public string status { get; set; }
public VoiceBaseListClass()
: base()
{
this.action = "list";
this.status = "processing";
}
}
public class ResponseVoiceBaseListClass
{
public string requestStatus { get; set; }
public string statusMessage { get; set; }
public string fileStatus { get; set; }
public List<string> mediaIds { get; set; }
public ResponseVoiceBaseListClass()
{
this.mediaIds = new List<string>();
}
}
Using the above classes the call that goes to the server is
/json/syncreply/VoiceBaseListClass?action=list&status=processing&version=1.0&apikey=API&Password=password
Is there a way I can force the service stack client to go to the
/Services
instead of
/json/syncreply/VoiceBaseListClass
I found a way to do this and it is working great for me.
[RestService("/services", "GET")]
public class VoiceBaseListClass : VoiceBaseBaseClass, IReturn<ResponseVoiceBaseListClass>
{
}
Although this is a deprecated attribute - the new attribute is called Route

I'm getting below shown error while returning the Activity object array.Not able understand where things are going wrong.Can any one help me with this .
Here is the error
End element 'ActivityTypeId' from namespace

i`m not sure but i think the issue is the alphabetical order of the datamember of your Activity class. just for testing, consider specifying the order property in the Datamember attribute.
