Asp.Net Core Blazor Logout does not work (redirecting to unavailable path)

Question

Hey there,

I'm facing a issue, that the user cannot log out, because the logout does get redirected to a path that's non existend.
I've tried scaffolding the identity framework again, but this didn't help either.

If I use the Account/LogOut or /Account/LogOut url the user gets redirected to: https://localhost:7172/Account/Login?ReturnUrl=%2FIdentity%2FAccount%2FLogOut.
I also tried Logout instead of LogOut. Didn't help either.
The route doesn't exist because I get the router defined message for there is nothing: Sorry, there's nothing at this address.

I'm using the logout call like this: (I'm using Mudblazor, thus the MudButton component usage. But this doesn't work with a default html button either)

<form method="post" action="Identity/Account/LogOut">  
    <MudButton ButtonType="ButtonType.Submit" Variant="Variant.Outlined" Color="Color.Info">  
        Ausloggen  
    </MudButton>  
</form>  

I'm using a Cookie authentication, that has been configured the following way:

builder.Services.AddAuthentication("Identity.Application").AddCookie();  
builder.Services.ConfigureApplicationCookie(options => { });  

And haven't changed the logout scaffolded .cshtml

@page  
@using Microsoft.AspNetCore.Identity  
@using Microsoft.AspNetCore.Authentication  
@attribute [IgnoreAntiforgeryToken]  
@inject SignInManager<WaWiIdentityUser> SignInManager  
  
@functions {  
  
    public async Task<IActionResult> OnPost()  
    {  
        if (SignInManager.IsSignedIn(User))  
        {  
            await SignInManager.SignOutAsync();  
        }  
  
        return Redirect("/");  
    }  
  
}  

Edit:

I checked the server answer, and as a result the client gets the status code 302 and the mentioned url: https://localhost:7172/Account/Login?ReturnUrl=%2FIdentity%2FAccount%2FLogout
I also tried setting the LogoutPath in the authentication and the applicationcookie but this doesn't help either.

builder.Services.AddAuthentication("Identity.Application")  
    .AddCookie(options => options.LogoutPath = "/Identity/Account/Logout");  
builder.Services.ConfigureApplicationCookie(options =>  
{  
    options.LogoutPath = "/Identity/Account/Logout";  
});  

Thanks ahead for any help!

After a long search, I created the LogoutModel by myself, assigned the Logout.cshtml the LogoutModel and now it's working fine :)

This is my final result:

[AllowAnonymous]  
[IgnoreAntiforgeryToken]  
public class LogoutModel : PageModel  
{  
    private readonly SignInManager<WaWiIdentityUser> _signInManager;  
    private readonly ILogger<LogoutModel> _logger;  
  
    public LogoutModel(SignInManager<WaWiIdentityUser> signInManager, ILogger<LogoutModel> logger)  
    {  
        _signInManager = signInManager;  
        _logger = logger;  
    }  
  
    public void OnGet()  
    {  
    }  
      
      
  
    public async Task<IActionResult> OnPost()  
    {  
        await _signInManager.SignOutAsync();  
        await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);  
        _logger.LogInformation("User logged out.");  
        return Redirect("Login");  
    }  
}  

Answer 2

For your final results I assume you created "LogOut.cshtml.cs"?

What changes did you make to "LogOut.cshtml"?

Answer 3

my solution to this problem:

LogOut.cshtml:

@page
@model LogoutModel

and LogOut.cshtml.cs:

using Microsoft.AspNetCore.Authentication.Cookies;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Identity;
using Microsoft.AspNetCore.Mvc.RazorPages;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Authentication;
[AllowAnonymous]
[IgnoreAntiforgeryToken]
public class LogoutModel : PageModel
{
    private readonly SignInManager<IdentityUser> _signInManager;
    public LogoutModel(SignInManager<IdentityUser> signInManager)
    {
        _signInManager = signInManager;
    }
    public async Task<IActionResult> OnPost()
    {
        await _signInManager.SignOutAsync();
        await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
        return Redirect("Login");
    }
}
