消息发布/订阅系统 kaca
kaca 是用 golang 语言开发的基于 websocket 协议的消息发布/订阅系统。
服务器端代码：
<pre class="brush:cpp ;toolbar: true; auto-links: false;">package main
import (
"github.com/scottkiss/kaca"
)
func main() {
//use true to set check origin
kaca.ServeWs(":8080",true)
}</pre>
发布订阅客户端：
<pre class="brush:cpp ;toolbar: true; auto-links: false;">package main
import (
"fmt"
"github.com/scottkiss/kaca"
"time"
)
func main() {
producer := kaca.NewClient(":8080", "ws")
consumer := kaca.NewClient(":8080", "ws")
consumer.Sub("say")
consumer.Sub("you")
consumer.ConsumeMessage(func(message string) {
fmt.Println("consume =>" + message)
})
time.Sleep(time.Second * time.Duration(2))
producer.Pub("you", "world")
producer.Pub("say", "hello")
time.Sleep(time.Second * time.Duration(2))
}</pre>
广播客户端：
<pre class="brush:cpp ;toolbar: true; auto-links: false;">package main
import (
"fmt"
"github.com/scottkiss/kaca"
"time"
)
func main() {
producer := kaca.NewClient(":8080", "ws")
consumer := kaca.NewClient(":8080", "ws")
c2 := kaca.NewClient(":8080", "ws")
c2.ConsumeMessage(func(message string) {
fmt.Println("c2 consume =>" + message)
})
consumer.Sub("say")
consumer.Sub("you")
consumer.ConsumeMessage(func(message string) {
fmt.Println("consume =>" + message)
})
time.Sleep(time.Second * time.Duration(2))
producer.Broadcast("broadcast...")
time.Sleep(time.Second * time.Duration(2))
})
}</pre>
