你可以获取所有的响应代码，是否需要为每个代码显示不同的页面由你决定。
例如，使用 UseStatusCodePagesWithReExecute 中间件：
Program.cs:
app.UseStatusCodePagesWithReExecute("/Home/Error", "?statusCode={0}");
Controller:
public IActionResult Error(int? statusCode = null)
{
if (statusCode.HasValue)
{
ViewData["Message"] = statusCode;
return View("ErrorPage");
}
return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
}
[Route("ErrorPage")]
public IActionResult ErrorPage()
{
return View();
}
在 ErrorPage.cshtml 中，你可以使用 ViewData["Message"] 获取响应代码并显示不同的内容。
或者你可以为每个响应代码创建一个视图，就像这样。
有关更多详细信息，你可以参考这个文档。

You can get all the response codes, it's up to you whether you need to display a different page for each code.
For example, use UseStatusCodePagesWithReExecute middleware:
Program.cs:
app.UseStatusCodePagesWithReExecute("/Home/Error", "?statusCode={0}");
Controller:
public IActionResult Error(int? statusCode = null)
{
if (statusCode.HasValue)
{
ViewData["Message"] = statusCode;
return View("ErrorPage");
}
return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });
}
[Route("ErrorPage")]
public IActionResult ErrorPage()
{
return View();
}
In ErrorPage.cshtml, you can use ViewData["Message"] to get the response code and display different content for it.
Or you can create a view for each response code like this.
