How do I get the ID in onget and the use handler in asp.net core razor page?

Question

I have a razor page for editing information in which I take the ID as input in onget. On this page, I want my handler to be called if a button is clicked. To do this, I need to use @page "{handler?}" in the code. But I also need to use @page "{id}" to get the ID. How is it possible to use both on one page?

@page "{id}"
<form asp-page-handler="test" method="post">

         <button >test </button>

</form>

 public IActionResult OnPosttest()

{
      //my code
}

public void OnGet(long id)
{

}

You do not need to add @page "{handler?}",

You just need to change OnPost t est to OnPost T est, use capitalization instead, that is the razor

page naming convention, and then the method can be called.

But I also need to use @page "{id}" to get the ID. How is it possible to use both on one page?

you can use this format

@page "{handler?}/{id?}"

to use both on one page.
