Im new to DI libraries and trying to use Autofac in a WebApi 2 project with Owin. This is my Owin Startup class,
[assembly: OwinStartup(typeof(FMIS.SIGMA.WebApi.Startup))]
namespace FMIS.SIGMA.WebApi
{
public class Startup
{
public void Configuration(IAppBuilder app)
{
var builder = new ContainerBuilder();
var config = new HttpConfiguration();
WebApiConfig.Register(config);
builder.RegisterApiControllers(Assembly.GetExecutingAssembly());
var container = builder.Build();
config.DependencyResolver = new AutofacWebApiDependencyResolver(container);
app.UseAutofacMiddleware(container);
app.UseAutofacWebApi(config);
app.UseWebApi(config);
ConfigureOAuth(app);
}
public void ConfigureOAuth(IAppBuilder app)
{
OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
{
AllowInsecureHttp = true,
TokenEndpointPath = new PathString("/token"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(1),
Provider = new SimpleAuthorizationServerProvider()
};
// Token Generation
app.UseOAuthAuthorizationServer(OAuthServerOptions);
app.UseOAuthBearerAuthentication(new OAuthBearerAuthenticationOptions());
}
}
}
When I call a Api method I get this error
An error occurred when trying to create a controller of type 'MyController'. Make sure that the controller has a parameterless public constructor.
What am I missing here?
MyController code is something like this
public class MyController : ApiController
{
ISomeCommandHandler someCommanHandler;
public MyController(ISomeCommandHandler SomeCommandHandler)
{
this.someCommanHandler = SomeCommandHandler;
}
// POST: api/My
public void Post([FromBody]string value)
{
someCommanHandler.Execute(new MyCommand() {
Name = "some value"
});
}
// GET: api/My
public IEnumerable<string> Get()
{
}
// GET: api/My/5
public string Get(int id)
{
}
}
