我尝试创建一个电子商务网站。我有一个带有“添加到购物车”按钮的产品页面。在此页面（
SingleProduct.cshtml@model Product@model.ProductId这是我的观点：

这是我的控制器：
using Microsoft.AspNetCore.Mvc;
using Microsoft.EntityFrameworkCore;
using Store02.Model;
using System.Collections.Generic;
namespace Store02.Controllers
{
public class ProductController : Controller
{
private readonly ProductContext _context;
public ProductController(ProductContext context)
{
_context = context;
}
public IActionResult Index()
{
Product Deneme = new Product();
var model = _context.Products.ToList();
return View(model);
}
public IActionResult Get(int id)
{
Product product = _context.Products.First(p => p.ProductId.Equals(id));
return View(product);
}
/* public IActionResult Products(int id=0)
{
Product Deneme = new Product();
List<Product> model;
if (id != 0)
{
model = _context.Products
.Where(p => p.CategoryId == id)
.ToList();
}
else
{
model = _context.Products.ToList();
}
return View(model);
}*/
public IActionResult SingleProduct(int id)
{
Product product = _context.Products.FirstOrDefault(p => p.ProductId == id);
if (product == null)
{
// Handle the case when the product is not found, for example, redirect to an error page.
return NotFound();
}
return View(product);
}
[HttpPost]
public IActionResult feedback(int id, int quantity)
{
Product product = _context.Products.FirstOrDefault(p => p.ProductId == id);
if (product == null)
{
return NotFound();
}
RepositoryOrderDetail.Add(product,quantity);
return View("feedback", RepositoryOrderDetail.orders);
}
}
}
我尝试使用 asp-route- 进行调用，但没有成功。
<div class="main-border-button">
<a asp-controller="Product" asp-action="feedback"
asp-route-id="@Model.ProductId"
asp-route-quantity=quantity>Add To Cart</a>
</div>
看一下
我认为“添加到购物车”不应该去反馈，但尽管如此，这就是它的样子。根据需要进行更改。
确保您有一个明确表示使用
[HttpPost]参见：理解MVC中的[HttpPost]、[HttpGet]和复杂Actionmethod参数
示例：
[HttpPost]
public IActionResult Feedback(Product model)
{
}
您想要发布整个模型。它会让你的生活更轻松。这样您就可以使用模型返回发布的值以及对数据所做的任何更改，并将其直接返回到视图。
不要使用
<form asp-controller="product" asp-action="feedback" method="post">让 razor 视图代替表单标签来完成这项工作。这也可以保证您的 html 不会过时，以防未来版本发生任何变化。
// Inside Index.cshtml
@using (Html.BeginForm("Feedback", "Product", FormMethod.Post))
{
// your html here
}
参见问题的答案：带有按钮单击的 Html Beginform 在 .net core mvc 中不起作用
这将使 razor 为您渲染表单 html 并消除猜测。
