ASP.Net MVC 5-在控制器外部访问HttpContext.Current.User的正确方法？

Question

I have an ASP.NEt MVC 5 application which uses a service to access information about the user.

Currently I pass it as a parameter to the method in the service class or do the following in each method where its required:

if (HttpContext.Current.User.Identity.IsAuthenticated)
{
        var user = HttpContext.Current.User;

        // do some stuff
}

How can I refactor the code to lets say inject it into the constructor of the class so that its available to any method in the class or is it correct the way i'm doing it at present eg passing it as a parameter?

public class ViewModelBuilderService : IViewModelBuilderService
{
    private readonly IUnitOfWork _unitOfWork;


    public ViewModelBuilderService(IUnitOfWork unitOfWork)
    {
        _unitOfWork = unitOfWork; 

    }

    // Other methods...

}

First of all why your business layer should at all need to know HttpContext . It shouldn't ... in case if at all needed then store the data into a variable and pass it to the method you are calling. Currently the approach you are following.

Probably you can try accessing the System.Threading.Thread.CurrentPrincipal in order to get the authentication context
