找不到網址Azurewebsite的網頁

Question

我將應用程序部署到Azurewebsite，並且在測試應用程序時發現一個錯誤。 當我想將產品添加到Bag時，Bag不會顯示已添加產品，並且當我按Bag的圖標時會顯示錯誤

This granihouse.azurewebsites.net page can’t be found No webpage was found for the web address: https://granihouse.azurewebsites.net/Customer/ShoppingCart
HTTP ERROR 404

到目前為止，我所做的就是嘗試使用FileZilla在localhost IIS上部署應用程序並獲取文件並將其傳輸到服務器，並且沒有任何變化。 我所做的第二件事是嘗試更改連接字符串，並嘗試在Visual Studio中部署應用程序，但是同樣存在同樣的問題。

        [BindProperty]

            ShoppingCartVM = new ShoppingCartViewModel()

                                                                        .AddMinutes(ShoppingCartVM.Appointments.AppointmentTime.Minute);

                };
                _db.ProductsSelectedForAppointment.Add(productSelectedForAppointment);

            }
            _db.SaveChanges();
            lstCartItem = new List<int>();
            HttpContext.Session.Set("ssShoppingCart", lstCartItem);

            return RedirectToAction("AppointmentConfirmation", "ShoppingCart", new { Id = appointmentId});
        }



        public IActionResult Remove(int id)
        {
            List<int> lstCartItem = HttpContext.Session.Get<List<int>>("ssShoppingCart");

            if(lstCartItem.Count > 0)
            {
                if(lstCartItem.Contains(id))
                {
                    lstCartItem.Remove(id);
                }
            }
            HttpContext.Session.Set("ssShoppingCart", lstCartItem);

            return RedirectToAction(nameof(Index));
        }


        //Get
        public IActionResult AppointmentConfirmation(int id)
        {
            ShoppingCartVM.Appointments = _db.Appointments.Where(a => a.Id == id).FirstOrDefault();
            List<ProductsSelectedForAppointment> objProdList = _db.ProductsSelectedForAppointment.Where(p => p.AppointmentId == id).ToList();


            foreach(ProductsSelectedForAppointment prodAtpObj in objProdList)
            {
                ShoppingCartVM.Products.Add(_db.Products.Include(p => p.ProductTypes).Include(p => p.SpecialTags).Where(p => p.Id == prodAtpObj.ProductId).FirstOrDefault());
            }
            return View(ShoppingCartVM);
        }
    }
}

看來Azure無法識別ShoppingCart控制器。 有什么建議可能是問題嗎？

如果您的站點在本地運行良好，我將檢查如何配置依賴項。 當我訪問https://granihouse.azurewebsites.net/時，我收到超時錯誤。 假設您在Visual Studio中使用右鍵單擊發布，那么我認為ApplicationDbContext指向您的應用程序服務存在問題。 另外， lstShoppingCart可以為null，這意味着在檢查.Count時可能會拋出NullReferenceException，在這種情況下，不會返回您的View。
