Redis发布/订阅

Redis实现了发布/订阅消息传递机制。

它的概念很简单:发布者在频道上发送消息。多个订户收到它。

订阅频道使用

SUBSCRIBE <channel>

Publish to a channel using

PUBLISH <channel> <message>

Example:

SUBSCRIBE dogs

In another redis-cli window, type:

PUBLISH dogs "Roger"

Messages will be sent to the subscribers, and they’ll by default display the kind of event, the channel, and the message:

Subscribers can listen on multiple channels:

SUBSCRIBE dogs cats

and will receive messages coming from all of them.
