使用Redirect跳转

[HttpGet("/Redirect")]
public IActionResult Redirect(string url, string title = null, bool sucess = true) {
    ViewRedirect model = new ViewRedirect();
    model.Url = url.IsNullOrEmpty() ? "/Index" : url;
   
    model.IsSucess = sucess;
    if (model.IsSucess) {
        model.Title = title.IsNullOrEmpty() ? "操作成功" : title;
    }else {
        model.Title = title.IsNullOrEmpty() ? "操作失败" : title;
    }
    return View(model);
}

  url = $@"/Redirect?url={url}&title=会员注册成功";
  return Redirect(url);
