.NET Core Audit Logging - api

Question

I want to implement audit logging in my .NET Core application.
Something like
[HttpPost, Auditing]
public dynamic SomeApiAction()
{
// API code here
...
}
The Attribute should be able to intercept the API call before and after execution in order to log.
Is there any such mechanism available in .net core as a part of the framework? I don't want to use any third-party component.
Please advise.

Answer 1

You can try Audit.WebApi library which is part of Audit.NET framework. It provides a configurable infrastructure to log interactions with your Asp.NET Core Web API.
For example using attributes:
using Audit.WebApi;
public class UsersController : ApiController
{
[HttpPost]
[AuditApi(IncludeHeaders = true)]
public IHttpActionResult Post()
{
//...
}
}

Answer 2

You can use CustomActionFilter for it like
public class CustomDemoActionFilter : Attribute, IActionFilter
{
public void OnActionExecuting(ActionExecutingContext context)
{
var controller = context.Controller as Controller;
if (controller == null) return;
var controllerName = context.RouteData.Values["controller"];
var actionName = context.RouteData.Values["action"];
var message = String.Format("{0} controller:{1} action:{2}", "onactionexecuting", controllerName, actionName);
var CurrentUrl = "/" + controllerName + "/" + actionName;
bool IsExists = false;
if(CurrentUrl=="/Home/Index")
{
IsExists=true;
}
else
{
IsExists=false;
}
if (IsExists)
{
//do your conditional coding here.
//context.Result = new RedirectToRouteResult(new RouteValueDictionary { { "controller", "Home" }, { "action", "Index" } });
}
else
{
//else your error page
context.Result = new RedirectToRouteResult(new RouteValueDictionary { { "controller", "Home" }, { "action", "Error" } });
}
//base.OnActionExecuting(context);
}
public void OnActionExecuted(ActionExecutedContext context)
{
}
}
and just use this customactionfilter as attribute over your action method like
[HttpGet]
[CustomHMISActionFilter]
public IActionResult Registration()
{
//your code here
}
