Razor @page 路由到不同的页面

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.

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 :
