Hyperf 已經實現了基於 AMQP 的訂閱與釋出，這裡給大家實現另外一種方式，來玩一下 Redis 的訂閱與釋出。
此方法在訂閱與釋出中，不是最優選，所以框架並沒有支援。如果是線上專案還是推薦使用
AMQP來做訊息佇列。

Do you want to remove the existing VCS (.git, .svn..) history? [Y,n]? Y定義佇列
我們希望可以監聽多個佇列，所以便把佇列名字額外定義出來。

$redis->publish(Channel::TEST, $user);
return $this->response->success([
'user' => $user,
'method' => $method,
'message' => 'Hello Hyperf.',

}
}
啟動 Server，測試結果
$ curl http://127.0.0.1:9501/
{"code":0,"data":{"user":"Hyperf","method":"GET","message":"Hello Hyperf."}}
終端顯示如下
