YII2 URL manager suffixes for different formats?

Question

Yii

I could not find how to add .json .xml suffixes to the URL manager to change the response format formats to application/json application/xml respectively

Answer 1

'urlManager' => [
            'enablePrettyUrl' => true,
            'showScriptName' => false,
            'suffix' => '.html',
            'rules' => [
             ['pattern'=>'/', 'route' => 'site/index', 'suffix'=>false],
             ['pattern'=>'article/<url>', 'route' => 'article/one', 'suffix'=>'.html'],
             ['pattern'=>'api', 'route' => 'api/index', 'suffix'=>'.json'],
]

Answer 2

Unfortunately, everything is not so simple, there are two suffixes and they are different and this option is not suitable

something similar, but I did not find a working solution
