Redis native protocol Subscriber based on Swoole coroutine

基于 Swoole 协程的 Redis 原生协议订阅库

使用 Socket 直接连接 Redis 服务器,不依赖 phpredis 扩展,该订阅器有如下优点:

  • 平滑修改:可随时增加、取消订阅通道,实现无缝切换通道的需求。
  • 跨协程安全关闭:可在任意时刻关闭订阅。
  • 通道获取消息:该库封装风格参考 golang 语言go-redis 库封装,通过 channel 获取订阅的消息。

Installation

  • Swoole >= 4.4
composer require mix/redis-subscriber

订阅频道

  • 连接、订阅失败会抛出异常
$sub =new \Mix\Redis\Subscriber\Subscriber('127.0.0.1',6379,'',5);// 连接失败将抛出异常$sub->subscribe('foo','bar');// 订阅失败将抛出异常$chan =$sub->channel();while (true) {$data =$chan->pop();if (empty($data)) {// 手动close与redis异常断开都会导致返回falseif (!$sub->closed) {// redis异常断开处理var_dump('Redis connection is disconnected abnormally');        }break;    }var_dump($data);}

接收到订阅消息:

object(Mix\Redis\Subscriber\Message)#8 (2) {  ["channel"]=>  string(2) "foo"  ["payload"]=>  string(4) "test"}

全部方法
