定义队列

我们希望可以监听多个队列，所以便把队列名字额外定义出来。

        $method = $this->request->getMethod();

        $redis = di()->get(\Redis::class);

        $redis->publish(Channel::TEST, $user);

        return $this->response->success([

            'user' => $user,

            'method' => $method,

            'message' => 'Hello Hyperf.',

启动 Server，测试结果

$ curl http://127.0.0.1:9501/

{"code":0,"data":{"user":"Hyperf","method":"GET","message":"Hello Hyperf."}}

终端显示如下
