これは私のコントローラーです
public class SuggestionController : ApiController
{
public ISuggestionRepository Repository { get; private set; }
public SuggestionController(ISuggestionRepository repository)
{
this.Repository = repository;
}
// to post suggestion
[HttpPost]
[ActionName("PostSuggestion")]
public HttpResponseMessage PostSuggestion(Suggestion suggestion)
{
var answerCorrect = this.Repository.CreateSuggestion(suggestion);
if (answerCorrect == true)
return Request.CreateResponse(HttpStatusCode.OK);
else
return Request.CreateResponse(HttpStatusCode.Conflict);
}
}
これは NinjectWebCommon.cs の RegisterServices メソッドです
private static void RegisterServices(IKernel kernel)
{
kernel.Bind<ICompetitionRepository>().To(typeof(CompetitionRepository))
.WithConstructorArgument("serviceContext", new InMemoryDataContext<Competition>());
kernel.Bind<ISubmissionRepository>().To(typeof(SubmissionRepository))
.WithConstructorArgument("serviceContext", new InMemoryDataContext<Submission>());
kernel.Bind<IUserRepository>().To(typeof(UserRepository))
.WithConstructorArgument("serviceContext", new InMemoryDataContext<User>());
kernel.Bind<ISuggestionRepository>().To(typeof(SuggestionRepository))
.WithConstructorArgument("serviceContext", new InMemoryDataContext<Suggestion>());
}
しかし、私の提案コントローラーにはデフォルトのコンストラクターがなく、クライアントアプリからコントローラーにアクセスすると500内部サーバーが表示されるという例外が発生しています
ninject 依存関係が適切に機能していない場合、コントローラーがデフォルトのコンストラクターを持たないという例外が発生することはわかっていますが、以下は、提案コントローラーと同様に実装した別のコントローラーであり、完全に正常に機能しています。
public IUserRepository Repository { get; private set; }
public SSOController(IUserRepository repository)
{
this.Repository = repository;
}
[HttpPost]
[ActionName("PostUser")]
public HttpResponseMessage PostUser([FromBody]string id)
{
var accessToken = id;
var client = new FacebookClient(accessToken);
dynamic result = client.Get("me", new { fields = "name,email" });
string name = result.name;
string email = result.email;
var existingUser = this.Repository.FindByUserIdentity(name);
if (existingUser == null)
{
var newUser = new User
{
Username = name,
Email = email,
};
var success = this.Repository.CreateAccount(newUser);
if (!success)
{
return Request.CreateResponse(HttpStatusCode.InternalServerError);
}
//return created status code as we created the user
return Request.CreateResponse<User>(HttpStatusCode.Created, newUser);
}
return Request.CreateResponse(HttpStatusCode.OK);
}
}
どこが間違っているのかわかりません。何か提案があれば教えてください。
