  Question about difference between HTTPPOST and async Task<IactionResult>

  Apr 04, 2018 06:31 PM|coreysan|LINK

  I'm learning MVC Core 2, from two different instructors.

  One instructor posts with the [HTTPPOST] attribute, while the other

  codes the action with async Task<IactionResult>

  Do they basically do the same thing?

  E.G., Instructor 1:

  [HttpPost]
  public IActionResult Checkout(Order order)
  {
      ....
      return RedirectToAction(nameof(Completed));
  }
  else
  {
       return View(order);
  }
  
  

  Instructor 2:

  public async Task<IActionResult> Create(cls_a a)
  {

       ....

       {
            mydb.Add(serviceType);
            await mydb.SaveChangesAsync();
            return RedirectToAction(nameof(Index));

       }
  }

       return View(serviceType);
  }

  No, two completely different things.

  [HttpPost] is a action selector attribute that restricts the action to HTTP POST actions.

   async Task<IActionResult> is a return type that defines the method as an async method.

  Reading the docs or asking your instructors should help.
