Php Larvel:缺少必需的参数（我想创建一个产品列表）

我正在构建一个带有购物车功能的Laravel应用程序。我正在按照本网站（）中的说明进行小改动，以符合我想要构建的内容

我想做的是根据url的参数显示每个商店的产品列表

例如：

https://productlist/1 =>显示店铺1的产品列表

https://productlist/2 =>显示shop2的产品列表

我正试图按照我之前提到的网站做这件事，这里是我得到的错误

缺少[Route:shop][URI:menu/{user}]所需的参数。（视图：C:\Users\toyop\Desktop\myproject\resources\views\partials\navbar.blade.php） http://localhost:8000/menu/1

由于错误中提到了navbar.blade.php，我认为问题出在哪里，但在那里我找不到任何参数

这是我的密码

href=“{{route（'shop'）}}”
需要传入一个userHi-aynber，
route:：get（'/menu/{user}'，'CartController@shop“）->名称（“店铺”）不是你的意思吗？如果不太麻烦的话，你能告诉我怎么做吗？是路线的
{user}
部分丢失了。您需要传入用户或用户ID。嘿，我将其更改为
href=“{{url（'/menu/{user}'）}”
，现在它可以工作了。谢谢你的帮助；D
