我的控制器响应 HTTP ERROR 404

Question

当我尝试调用 https://localhost:44328/Products 时，我的产品控制器响应 HTTP ERROR 404

我的产品控制器

public class ProductsController : Controller
{
    private readonly CmsShoppingCartContext _context;

    public ProductsController(CmsShoppingCartContext context)
    {
        this._context = context;
    }

    // GET /products
    public async Task<IActionResult> Index(int p = 1)
    {

        //tag helper
        int pageSize = 6;
        //The skip is to skip 0, 1-1*6 is zero. So it starts with one
        var products = _context.Products.OrderByDescending(x => x.Id)
            .Skip((p - 1) * pageSize)
            .Take(pageSize);

        ViewBag.PageNumber = p;
        ViewBag.PageRange = pageSize;
        ViewBag.TotalPages = (int)Math.Ceiling((decimal)_context.Products.Count() / pageSize);

        return View(await products.ToListAsync());


    }

我的 Index.html（在文件夹 Views/Products 中）

由于您使用的是mapendpoints，请尝试将路由属性添加到端点

[Route("~/Products/{p?}")]
public async Task<IActionResult> Index(int p = 1)

另一种方法是映射控制器，但我不建议这样做，因为它非常令人困惑，并且并不总是按预期工作

[Route("~/Products")]
public class ProductsController : Controller

....

[HttpGet("{p?}")]
public async Task<IActionResult> Index(int p = 1)
