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AppEvents目录下新建RedisTest事件
<?phpnamespace AppEvents;use IlluminateBroadcastingChannel;use IlluminateQueueSerializesModels;use IlluminateBroadcastingPrivateChannel;use IlluminateBroadcastingPresenceChannel;use IlluminateFoundationEventsDispatchable;use IlluminateBroadcastingInteractsWithSockets;use IlluminateContractsBroadcastingShouldBroadcast;class RedisTest{ use Dispatchable, InteractsWithSockets, SerializesModels; public $message; /** * Create a new event instance. * * @return void */ public function __construct($message) { $this->message = $message; } /** * Get the channels the event should broadcast on. * * @return IlluminateBroadcastingChannel|array */ public function broadcastOn() { return new PrivateChannel('channel-name'); }}AppListenersRedisTestListener 监听事件代码
<?phpnamespace AppListeners;use AppEventsRedisTest;use IlluminateQueueInteractsWithQueue;use IlluminateContractsQueueShouldQueue;use IlluminateSupportFacadesLog;class 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); }}AppProvidersEventServiceProvider 登记事件/监听关系
protected $listen = [ 'AppEventsRedisTest' => [ 'AppListenersRedisTestListener', ], ];
监听命令
AppConsoleCommandsRedisSubscribe 代码如下
<?phpnamespace AppConsoleCommands;use IlluminateConsoleCommand;use swoole_redis;use IlluminateSupportFacadesEvent;use AppEventsRedisTest;class RedisSubscribe extends Command{ /** * 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 $more = false; if (!$more and $result[0] == 'message') { echo "trigger Event RedisTestn"; Event::fire(new RedisTest($result[2])); } }); $client->connect('127.0.0.1', 6379, function (swoole_redis $client, $result) { echo "connectn"; $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/echouser=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/echouser=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 storagelogslaravel.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
