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 ? <?php
namespace 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 <?php
namespace 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 <?php
namespace 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]));
}
});
$client->connect('127.0.0.1',6379,$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:work directory=/home/bella/Downloads/lnmp/echo1.0/echo user=bella autorestart=true redirect_stderr=true stdout_logfile=/home/bella/Downloads/lnmp/echo1.0/echo/storage/logs/queue.log loglevel=info [program:echo-redis] command=php artisan redis:subscribe directory=/home/bella/Downloads/lnmp/echo1.0/echo user=bella autorestart=true redirect_stderr=true stdout_logfile=/home/bella/Downloads/lnmp/echo1.0/echo/storage/logs/redis.log loglevel=info
完成后，执行以下命令重载 ================================= 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 （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
