Using laravel as an example, create a middleware App\Http\Middleware\Remind.php

public function handle($request, Closure $next)
{
  $key = $request->input('key', '');
  if (
    $key != 'abc'
    || !in_array($request->ip(), ['10.0.123.2'])
  ) {
    return response()->json([
      'code' => 403,
      'msg' => 'access error',
    ], 403);
  }
  return $next($request);
}
