在Laravel中不使用按钮和ajax的自动过滤

<form action="/filter" method="POST">
    @csrf
    <input type="text" name="filter" placeholder="输入过滤条件">
    <button type="submit">提交</button>
</form>

Route::post('/filter', 'FilterController@filter')->middleware('filter');

namespace App\Http\Middleware;

use Closure;

class FilterMiddleware
{
    public function handle($request, Closure $next)
    {
        $filter = $request->input('filter');
        
        // 在这里对$filter进行处理，可以根据业务需求进行过滤操作
        
        return $next($request);
    }
}

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class FilterController extends Controller
{
    public function filter(Request $request)
    {
        // 处理过滤后的逻辑
        
        return response()->json(['message' => '过滤成功']);
    }
}

protected $routeMiddleware = [
    // ...
    'filter' => \App\Http\Middleware\FilterMiddleware::class,
];
