middleware中执行参数解析导致s参数进入

在middleware中执行$request->param()后,后续在controller中执行dump($request->param())会导致"s" => "/ab/123"进入入参数组.
```

//middleware伪代码
    public function handle(Request $request, Closure $next): mixed
    {
   $request->param();
   }

//controller伪代码
    public function index(Request $request)
    {
        dump($request->param());//输出array中会多出s参数
    }

```
