Customaze API Attribute

Good afternoon, I study .NET CORE. How to create a custom attribute for the controller API? I want to allow requests to controllers from certain ip addresses.
In ASP. Net framework I created a custom attribute inheriting from "AuthorizeAttribute" then I just add my attribute to my controller.
I want that controller work from specific Ip address
Create attribute inherited from IAuthorizationFilter to have similar behavior to previous ASP.NET framework.
public class IpAuthorizationAttribute : AuthorizeAttribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationFilterContext context)
{
if (/*ip not allowed*/)
{
//return 401 Unauthorized
context.Result = new UnauthorizedResult();
}
}
}
However, Microsoft recommends policy based authorization for ASP.NET Core.

With the Server-side model using the project template where can I place an api controller that is externally accessible?

With a server-side Blazor for an intranet app, using the project template, where would one place api controllers? In the .Client project or the .Server project?
In other words, I want an api that is within the same web app, accessible via a path like this it-app.something-internal-route.net/api
You need to put your API into your Controller which is inside Server Assembly
[Route("api/[controller]")]
public class SampleDataController : Controller
{
[HttpGet("[action]")]
public IActionResult Get()
{
return Ok(<your result list / object>)
}
}

How to obtain HttpRequestMessage outside of controller

I have a Web API v2 controller that makes a method call out to a service in the same project. The service uses the UrlHelper class to put together a URL however, the UrlHelper class needs the HttpRequestMessage in order to build the proper URL.
How can I obtain the HttpRequestMessage from within a class (my service) that is outside of the API controller? Can I pass the HttpRequestMessage into the service method? Is there another way to access from a global context?
I am using a self-hosted environment (OWIN).
public class FooController : ApiController
{
public IHttpActionResult BarAction()
{
UrlHelper urlHelper = GetUrlHelperFromWhereever();
urlHelper.DoSomething( this.Request );
}
this.Request is HttpRequestMessage: https://msdn.microsoft.com/en-us/library/system.web.http.apicontroller.request(v=vs.118).aspx#P:System.Web.Http.ApiController.Request

Checking if the user is logged in asp.net mvc

In my application I am restricting some view and the user has to be logged in to view them. One way would be to check on every action if the user is logged in or not. But after a bit of research I found that asp.net MVS supports some global filter rules.
How do we use them? Ideally I would want to call a filter onBeforeAction and check if the user is logged in or not..
Is this a right approach? If yes, then can any body give me an example?
The easiest way is to add the Authorize attribute to your controller or action methods. For example:
public class MyController : Controller
{
//Normal action
public ActionResult DoSomethingForAnyone() { }
//Secured action
[Authorize]
public ActionResult DoSomethingOnlyForAuthorisedUsers() { }
}
Alternatively you can secure the entire controller and exclude actions you want to be accessible to anonymous users:
[Authorize]
public class SecureController : Controller
{
public ActionResult DoSomething() { }
[AllowAnonymous]
public ActionResult DoSomethingForAnyone() { }
}
Your [Authorize] will not work with the custom login. If you are using Form Authentication or other Authentication method than [Authorize] will work smoothly.
For custom login on success set
FormsAuthentication.SetAuthCookie([user name], false);
This will make your [Authorize] attribute to work properly.
And for logout use below statement
FormsAuthentication.SignOut();
If you follow the above solution than it will reduce your code as well as valid user check on before Action call.

MVC Controller, testing a WCF service that is wrapped in a proxy

I am trying to figure how to create tests for my controllers that are consuming a WCF service (via a proxy class)
The proxy class is pretty much identical to the one listed in this post http://blog.weminuche.net/2008/08/test-post.html
Base Controller
public abstract class ServiceProxyController<TService> : Controller
where TService : class
{
private readonly ServiceProxy<TService> _proxyHelper;
protected ServiceProxyController(string endpoint)
{
_proxyHelper = new ServiceProxy<TService>(endpoint);
}
private Stuff GetStuff(int num)
{
Call((service) => {
service.DoSomeStuff(num)
});
................
}
...........
}
Controller Implementation
public class MyController : ServiceProxyController<IService>
{
public MyController() : base("ServiceBindingName")
{
}
}
I want to be able to inject a proxy helper(???) into my controller so as I can mock it and therefor test the controller
How about injecting the proxy helper to the constructor (notice the introduction of an abstraction):
private readonly IServiceProxy<TService> _proxyHelper;
protected ServiceProxyController(IServiceProxy<TService> proxyHelper)
{
_proxyHelper = proxyHelper;
}
and the controller:
public MyController(IServiceProxy<TService> proxyHelper)
: base(proxyHelper)
{
}
This way in your unit test when instantiating the controller you could inject a mocked instance of the IServiceProxy<TService> interface.
You will then need to configure your DI framework to insert the proper implementation into the controller constructor which will wrap the actual ChannelFactory.
I just asked a similar question. I am injecting the service using structure map. I am dynamically creating a proxy using channel factory.
Look at this example for using Channel factory.
creating WCF ChannelFactory<T>
My question for your reference.
