How to get access to property inside ActionFilter?-CodePudding

Here is my ActionFilter:

public class LogAttribute : ActionFilterAttribute
{
    public LogAttribute(ILoggerFactory logger)
    {
        Logger = logger.CreateLogger<LogAttribute>();
    }

    public string UserId { get; set; }

    public string Path { get; set; }

    public ILogger Logger { get; }

    public override void OnActionExecuting(ActionExecutingContext context)
    {
        var controller = context.Controller as Controller;
        UserId =  User.FindFirstValue(ClaimTypes.NameIdentifier);
        Path = $"{context.HttpContext.Request.Path.Value}[{context.HttpContext.Request.Method}]";
        Logger.LogDebug($"{Path} started. User(id): {UserId}.");
    }
}

I want to use UserId and Path properties in other places of my controllers. Is there laconic way to do it?

CodePudding user response：

If I get the question right... We're trying to pull UserId and Path (maybe query string) out of current Http Requet ?

If so, try this

public class LogAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext context)
    {
        var userId = context.HttpContext.User.FindFirst(ClaimTypes.NameIdentifier); // claims type depend on how we configure authentication. But many default fall into this constants.
        var path = context.HttpContext.Request.Path;
        var queryString = context.HttpContext.Request.QueryString;
        //... Do whatever we need
    }
}

CodePudding user response：

you can create basecontroller

public class BaseController : Controller
    {
      public BaseController(ILoggerFactory logger)
    {
        Logger = logger.CreateLogger<LogAttribute>();
    }

    protected string UserId { get; set; }

    protected string Path { get; set; }

    protected ILogger Logger { get; }
    
        [NonAction]
        public override void OnActionExecuting(ActionExecutingContext context)
        {
       var controllerActionDescriptor = context.ActionDescriptor as 
         ControllerActionDescriptor;
            var controllerName = controllerActionDescriptor?.ControllerName;
            var actionName = controllerActionDescriptor?.ActionName;
        UserId =  User.FindFirstValue(ClaimTypes.NameIdentifier);
        Path = $"{context.HttpContext.Request.Path.Value}[{context.HttpContext.Request.Method}]";
        Logger.LogDebug($"{Path} started. User(id): {UserId}.");
    }
}
