GitHub - mix-php/redis-subscriber: Redis native protocol Subscriber based on Swoole coroutine

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。

• Swoole >= 4.4

composer require mix/redis-subscriber

• 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false
        if (!$sub->closed) {
            // redis异常断开处理
            var_dump('Redis connection is disconnected abnormally');
        }
        break;
    }
    var_dump($data);
}

接收到订阅消息：

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