1.服务端代码 

【备注:这是服务端没秒发送一个数据导发布频道里面】

package main

import (
  "fmt"
  "github.com/go-redis/redis"
  "math/rand"
  "time"
)
func main(){
  redisConnect()
}
func redisConnect(){
  server:=redis.NewClient(&redis.Options{
    Addr:"127.0.0.1:6379",
    DB:0,
  })
  for i:=0;i<20;i++ {
    time.Sleep(time.Second)
    rand.Seed(time.Now().Unix())
    num:=rand.Intn(1000)
    n,_:=server.Publish("channel",num).Result()
    fmt.Println(n)
  }
}

2.这是客户端代码

package main

import (
  "fmt"
  "github.com/go-redis/redis"
)

func main(){
  redisClient()
}

func redisClient(){
  client:=redis.NewClient(&redis.Options{
    Addr:"127.0.0.1:6379",
    DB:0,
  })
  pubsub:=client.Subscribe("channel")
  defer  pubsub.Close()
  for msg:= range pubsub.Channel() {
    fmt.Println(msg.Payload)
  }
}

问题思考:

1.第一如果订阅端挂了怎么办

2.第二发布数据过多处理不过来怎么做

3.重复发布怎么办
