Razor #page routing to a different page - asp.net-core

Question

I'm using aspnet core 3.
In a controller, my user can type in a single url like ... /login ... and then I test which company it is and return the correct view - like this:
[Route("login")]
public IActionResult Login()
{
return _company == "a" ? View("ThisView") : View("ThatView");
}
But if I use Razor routing ... #page "/login" ... how can I do the same? I need the user to type a single url, but then I need to test which company it is and then direct to the correct razor page.

Answer 1

You can use "RedirectToPageResult()" in razor page to return to
the corresponding page instead of view.
The premise is that you need to create the corresponding page to
return.
For example, I have a page named MyTest, user can input the parameter in this page.
If user enter "a" , then return to ThisPage.cshtml, otherwise, return to ThatPage.cshtml.
MyTest.cshtml:
#page
#model WebApplication1_rzaor_page.MyTestModel
#{
ViewData["Title"] = "MyTest";
Layout = "~/Pages/Shared/_Layout.cshtml";
}
<h1>MyTest</h1>
<form asp-page-handler="Login" method="post">
<input id="Text1" type="text" name="_company" />
<input id="Submit1" type="submit" value="submit" />
</form>
MyTest.cshtml.cs:
public class MyTestModel : PageModel
{
public void OnGet()
{
}
public IActionResult OnPostLogin(string _company)
{
return _company == "a" ? new RedirectToPageResult("ThisPage") : new RedirectToPageResult("ThatPage");
}
}
Here is the result :
