Do you need to call middleware from controller function in laravel app, if yes then i will show you simple example to run middleware from controller constructor using "$this->middleware".

you can also define middleware in controller file in laravel 6, laravel 7, laravel 8, laravel 9, laravel 10 and laravel 11 app.

Actually, i was working on my laravel 5.7 project. I need acl and i used entrust package for role and permission on my project. So i created products module with resource route. I require to add permission for each route. I thought if i add permission like for product create, product edit, product delete then i have to create several routes instead of resource route. But i found way to use middleware in controller method.

So, you can also use middleware in controller like as bellow example:

Example:

<?php
  
namespace App\Http\Controllers;
   
use App\Product;
use Illuminate\Http\Request;
   
class ProductController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('product-list', ['only' => ['index']]);
        $this->middleware('product-create', ['only' => ['index','create','store']]);
        $this->middleware('product-update', ['only' => ['index','edit','update']]);
        $this->middleware('product-delete', ['only' => ['index','delete']]);
    }
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $products = Product::latest()->paginate(5);
   
        return view('products.index',compact('products'))
            ->with('i', (request()->input('page', 1) - 1) * 5);
    }
    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        return view('products.create');
    }
  
    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
        ]);
   
        Product::create($request->all());
  
        return redirect()->route('products.index')
                        ->with('success','Product created successfully.');
    }
    /**
     * Display the specified resource.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function show(Product $product)
    {
        return view('products.show',compact('product'));
    }
  
    /**
     * Show the form for editing the specified resource.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function edit(Product $product)
    {
        return view('products.edit',compact('product'));
    }
   
    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, Product $product)
    {
        $request->validate([
            'name' => 'required',
            'detail' => 'required',
        ]);
   
        $product->update($request->all());
   
        return redirect()->route('products.index')
                        ->with('success','Product updated successfully');
    }
    /**
     * Remove the specified resource from storage.
     *
     * @param  \App\Product  $product
     * @return \Illuminate\Http\Response
     */
    public function destroy(Product $product)
    {
        $product->delete();
  
        return redirect()->route('products.index')
                        ->with('success','Product deleted successfully');
    }
}

I hope it can help you...
