I want to get the original path (entered by the user) in the error controller after redirect to the 404 error page ?!
public class ErrorViewModel
{
public string RequestId { get; set; }
public bool ShowRequestId => !string.IsNullOrEmpty(RequestId);
public string RequestedUrl { get; set; }
public string RedirectUrl { get; set; }
public string ExceptionMessage { get; set; }
}
and in Error Controller
return View("ErrorPage", new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier,
RequestedUrl = "", RedirectUrl = HttpContext.Request.GetDisplayUrl(), ExceptionMessage = ReasonPhrases.GetReasonPhrase(statusCode) });
CodePudding user response:
UPDATE:
You also can refer below method.
Startup.cs:
app.UseStatusCodePagesWithReExecute("/Home/Error", "?statusCode={0}");
ErrorViewModel.cs:
public class ErrorViewModel
{
public string RequestId { get; set; }
public bool ShowRequestId => !string.IsNullOrEmpty(RequestId);
public string RequestedUrl { get; set; }
public string RedirectUrl { get; set; }
public string ExceptionMessage { get; set; }
}
HomeController.cs:
public IActionResult Error()
{
var statusCode = HttpContext.Response.StatusCode;
ViewData["statusCode"] = statusCode;
var feauter = Request.HttpContext.Features.Get<IStatusCodeReExecuteFeature>();//=null
var path = feauter?.OriginalPath;
return View("ErrorPage", new ErrorViewModel
{
RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier,
RequestedUrl = path,
RedirectUrl = HttpContext.Request.GetDisplayUrl(),
ExceptionMessage = ReasonPhrases.GetReasonPhrase(statusCode)
});
}
ErrorPage.cshtml:
@model ErrorViewModel
@{
ViewData["Title"] = "ErrorPage";
}
<h1 >@ViewData["statusCode"]</h1>
<h2 >An error occurred while processing your request.</h2>
<div>RequestId :@Model.RequestId</div>
<div>ShowRequestId :@Model.ShowRequestId</div>
<div>RequestedUrl :@Model.RequestedUrl</div>
<div>RedirectUrl :@Model.RedirectUrl</div>
<div>ExceptionMessage:@Model.ExceptionMessage</div>

PREVIOUS:
If you want get request url and redirect url, I suggest you can use RedirectToAction
method.
Please check below page, if it is you want pls let me know.
And in my test code, I also use middleware to handle 302 event.
