How to Retrieve HttpContext.Current in ASP.NET Core

In ASP.NET Core, HttpContext.Current has been deprecated. This article explores alternative approaches to access the current HTTP context.

1. HttpContext Property

You can access the current HTTP context through the HttpContext property of controllers:

public class HomeController : Controller
{
    public IActionResult Index()
    {
        MyMethod(HttpContext);

        return View();
    }

    private void MyMethod(Microsoft.AspNetCore.Http.HttpContext context)
    {
        // Use the HTTP context here
    }
}

2. HttpContext Parameter in Middleware

In custom ASP.NET Core middleware, the current HTTP context is automatically injected as a parameter to the Invoke method:

public async Task InvokeAsync(HttpContext context)
{
    // Use the HTTP context here
}

3. HTTP Context Accessor

For classes not managed by ASP.NET Core dependency injection, the IHttpContextAccessor helper service can be used:

public class MyService
{
    private readonly IHttpContextAccessor _httpContextAccessor;

    public MyService(IHttpContextAccessor httpContextAccessor)
    {
        _httpContextAccessor = httpContextAccessor;
    }

    public void UseHttpContext()
    {
        var context = _httpContextAccessor.HttpContext;
        // Use the HTTP context here
    }
}

Don't forget to register HttpContextAccessor in ConfigureServices:

public void ConfigureServices(IServiceCollection services)
{
    services.AddHttpContextAccessor();

    // ...
}
