How to generate friendlyUrl for link in Yii2?

Question

Yii

I am learning yii2 and faced the problem of creating CNC. As I understand it, in urlManager, you can specify the rules by which the link is parsed into parameters and passed in acc. action, but I have figured out how to get the reverse process. The /helper/url class makes links like "/blog?category=other", not "/blog/other".
My config:

'urlManager' => [
  'enablePrettyUrl' => true,
  'showScriptName' => false,
  'rules' => [
    '<action:>' => 'site/<action>',
                '<action:[\w\-]+>/<category:[\w\-]+>' => 'site/<action>',
  ],
],

Answer 1

Solved the problem myself.

'rules' => [
        '<action:(contact|about)>' => 'site/<action>',
        'blog/<category>/<post>'=>'site/post',
        'blog/<category>'=>'site/blog',
        'blog'=>'site/blog',
],

Answer 2

with the problem of creating CNC

with the problem of routing requests ... CNC is machine tools.
Make sure to read the documentation before asking questions. Surely there will be some methods like createUrl('site/action', ['category'=>'name'])
