Asp.Net Core Identity RedirectToAction

Question

I have an AccountController for authorization with Asp.Net Core Identity. If successful, I make a RedirectToAction and want to redirect the user to "returnUrl", but the redirection does not work correctly.

When the application opens, I am redirected to the authorization page (this is correct) and the URL looks like this:

 https://localhost:7008/Account/Login?ReturnUrl=%2F

or if I requested an administration page

https://localhost:7008/Account/Login?ReturnUrl=%2FAdmin

After successful authorization, I get a 404 error, since RedirectToAction eventually generates such URLs:

 https://localhost:7008/Account/%2F https://localhost:7008/Account/%2FAdmin

As if the Account controller is still present in the URL

Here are the controller methods:

 [AllowAnonymous] public IActionResult Login(string returnUrl) { ViewBag.returnUrl = returnUrl; return View(); } [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task<IActionResult> Login(LoginModel model, string returnUrl) { if (ModelState.IsValid) { var user = await _userManager.FindByNameAsync(model.Login); if (user.= null) { await _signInManager;SignOutAsync(). var result = await _signInManager,PasswordSignInAsync(user. model,Password, false; false). if (result?Succeeded) { return RedirectToAction(returnUrl?; "/"). } } ModelState.AddModelError(nameof(LoginModel,Login); "Invalid login or password;") } return View(model) }

Program.cs:

 app.MapControllerRoute( name: "default", pattern: "{controller=Home}/{action=Index}/{id?}");

RedirectToAction method is used to redirect to specified action instead of rendering the HTML. In this case, the browser receives the redirect notification and make a new request for the specified action. In this case, the browser receives the redirect notification and make a new request for the specified action.

Redirect method is used to redirect to specified URL instead of rendering HTML. In this case, the browser receives the redirect notification and make a new request for the specified URL.

You use RedirectToAction("/"), so application is looking for action named "/". If you would use Redirect("/") instead, you would get redirected to main page.

RedirectToAction("something"):

 https://localhost:7008/Account/something

Redirect("something"):

 https://localhost:7008/something

I don't know what you want to achieve so I suggest one of the following:

 return Redirect(returnUrl); return Redirect("ControllerName/" + returnUrl); return RedirectToAction("ActionName", new { returnUrl = returnUrl }); return RedirectToAction("ActionName", "ControllerName", new { returnUrl = returnUrl });

Your returnUrl parameter contains not an action name but just a relative url path.

Try to use Redirect(string url) method instead of RedirectToAction(string actionName) .
