golang使用redis

redigo使用

手册地址：http://godoc.org/github.com/garyburd/redigo/redis

github地址：https://github.com/garyburd/redigo

获取地址，进入GOPATH使用go get下载包

go get github.com/garyburd/redigo/redis

连接redis读写数据

package main

import (
	"fmt"

	"github.com/garyburd/redigo/redis"
)

func main() {
	conn, err := redis.Dial("tcp", "localhost:6379")

	if err != nil {
		fmt.Println(err)
		return
	}

	_, err = conn.Do("set", "name", "golang redis test")

	if err != nil {
		fmt.Println(err)
	}
}

从redis中读出数据

package main

import (
	"fmt"

	"github.com/garyburd/redigo/redis"
)

func rr(conn redis.Conn, key string) {
	line, err := redis.String(conn.Do("get", key))

	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(line)
}

func main() {

	conn, err := redis.Dial("tcp", "localhost:6379")
	if err != nil {
		fmt.Println(err)
		return
	}

	rr(conn, "name")

}

注意：写入的值永远不会过期

设置key过期时间

func wr(conn redis.Conn, key, val interface{}, time int) {
	line, err := conn.Do("set", key, val, "EX", time)

	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(line)
}

wr(conn, "name", "zhangsan", 120)
