教你使用swoole监听redis数据

swoole如何监听redis数据？

laravel使用swoole监听redis

开始之前，请先确保redis已经正确安装，并正常运行。

laravel代码

在app\events目录下新建redistest事件

<?phpnamespace app\events;u illuminate\broadcasting\channel;u illuminate\queue\rializesmodels;u illuminate\broadcasting\privatechannel;u illuminate\broadcasting\prencechannel;u illuminate\foundation\events\dispatchable;u illuminate\broadcasting\interactswithsockets;u illuminate\contracts\broadcasting\shouldbroadcast;class redistest{    u dispatchable, interactswithsockets, rializesmodels;    public $message;    /**    * create a new event instance.    *    * @return void    */    public function __construct($message)    {        $this->message = $message;    }    /**    * get the channels the event should broadcast on.    *写作业有用吗    * @return \illuminate\broadcasting\channel|array    */    public function broadcaston()    {        return new privatechannel('channel-name');    }}

app\listeners\redistestlistener 监听事件代码

<?phpnamespace app\listeners;u app\events\redistest;u illuminate\queue\interactswithqueue;u ill甘草片的副作用uminate\contracts\queue\shouldqueue;u illuminate\support\facades\log;class十字对联 redistestlistener{    /**    * create the event listener.    *    * @return void    */    public function __construct()    {        //    }    /**    * handle the event.    *    * @param  redistest  $event    * @return void    */    public function handle(redistest $event)    {        $message = $event->message;        log::info('the message received from subscribed redis channel msg_0: '.$message);    }}app\举报材料providers\eventrviceprovider 登记事件/监听关系protected $listen = [        'app\events\redistest' => [            'app\listeners\redistestlistener',        ],    ];

监听命令

app\console\commands\redissubscribe 代码如下

<?phpnamespace app\console\commands;u illuminate\console\command;u swoole_redis;u illuminate\support\facades\event;u app\events\redistest;class redissubscribe extends command{    /** 治疗青春痘印的方法   * the name and signature of the console command.    *    * @var string    */    protected $signature = 'redis:subscribe';    /**    * the console command description.    *    * @var string    */    protected $description = 'deamon process to subscribe redis broadcast';    /**    * create a new command instance.    *    * @return void    */    public function __construct()    {        parent::__construct();    }    /**    * execute the console command.    *    * @return mixed    */    public function handle()    {        $client = new swoole_redis;        $client->on('message', function (swoole_redis $client, $result) {            var_dump($result);            static $more = fal;            if (!$more and $result[0] == 'message')            {                echo "trigger event redistest\n";                event::fire(new redistest($result[2]));            }        });        $client->connect('127.0.0.1', 6379, function (swoole_redis $client, $result) {            echo "connect\n";            $client->subscribe('msg_0');        });    }}

laravel部分代码完成

==================================

supervisor 管理进程

在 /etc/supervisor/conf.d 文件夹下新建 echo.conf , 代码如下

[group:echos]programs=echo-queue,echo-redis[program:echo-queue]command=php artisan queue:workdirectory=/home/bella/downloads/lnmp/echo1.0/echour=bellaautorestart=trueredirect_stderr=truestdout_logfile=/home/bella/downloads/lnmp/echo1.0/echo/storage/logs/queue.logloglevel=info[program:echo-redis]command=php artisan redis:subscribedirectory=/home/bella/downloads/lnmp/echo1.0/echour=bellaautorestart=trueredirect_stderr=truestdout_logfile=/home/bella/downloads/lnmp/echo1.0/echo/storage/logs/redis.logloglevel=info

完成后，执行以下命令重载

supervisorctl reload

=================================

进入redis 客户端，发布一个广播通知到 msg_0 频道

publish msg_0 "hello bella"

如果 laravel目录下的 storage\logs\laravel.log 最后的日志中记录了广播发送的通知，则redis监听功能实现
