If a request is sent via Accept: application/json; version=v1,
After content negotiation, yii\web\Response::$acceptParams will contain the value ['version' = > 'v1'].
But it is empty after printing. What is the reason?
var_dump((new Response())->acceptParams);

人生最曼妙的風(fēng)景，竟是內(nèi)心的淡定與從容！
var_dump(Yii::$app->response->acceptParams["sub-version"]);
就可以了，被手冊(cè)誤導(dǎo)了
