Question

这是我使用ninject的Owin启动类。我的应用程序完美地运行localhost但是当我将应用程序部署到azure网站时，我收到如下错误：

{
"message": "An error has occurred.",
"exceptionMessage": "An error occurred when trying to create a controller of type   CompanyController'. Make sure that the controller has a parameterless public constructor.",
"exceptionType": "System.InvalidOperationException","stackTrace": "at    System.Web.Http.Dispatcher.DefaultHttpControllerActivator.
Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type   controllerType)\r\n   at System.Web.Http.Controllers.HttpControllerDescriptor.
CreateController(HttpRequestMessage request)\r\n   at     System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__1.MoveNext()",
"innerException": {
    "message": "An error has occurred.",
    "exceptionMessage": "Type 'Sinerp.Api.Controllers.CompanyController' does not have a default constructor",
    "exceptionType": "System.ArgumentException",
    "stackTrace": "   at System.Linq.Expressions.Expression.New(Type type)\r\n   at System.Web.Http.Internal.TypeActivator.Create[TBase](Type instanceType)\r\n   at System.Web.Http.Dispatcher.DefaultHttpControllerActivator.GetInstanceOrActivator(HttpRequestMessage request, Type controllerType, Func`1& activator)\r\n   at System.Web.Http.Dispatcher.DefaultHttpControllerActivator.Create(HttpRequestMessage request, HttpControllerDescriptor controllerDescriptor, Type controllerType)"
  }}

我正在寻找很长一段时间。但结果令人失望。感谢ansvers

Owin配置应该是这样的。首先，我在调用UserWebApi后调用Ninject Middleware 并且像魅力一样工作

app.UseNinjectMiddleware(() => NinjectKernel)
   .UseNinjectWebApi(config);
app.UseWebApi(config);

使用Ninject将Web api 2应用程序部署到Azure时出错
