GO_Rredis

使用第三方开源的redis库 : github.com/garyburd/redigo/redis

安装

go get github.com/garyburd/redigo/redis

使用

首先要确认有redis

连接redis

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

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

	defer c.Close()
}

STRING操作

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

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

	defer c.Close()
	_, err = c.Do("Set", "abc", 100) // 添加一个名为abc的字符串
	if err != nil {
		fmt.Println(err)
		return
	}

	r, err := redis.Int(c.Do("Get", "abc")) // 去读
	if err != nil {
		fmt.Println("get abc failed,", err)
		return
	}

	fmt.Println(r)
}

批量创建

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

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

	defer c.Close()
	_, err = c.Do("MSet", "abc", 100, "efg", 300)
	if err != nil {
		fmt.Println(err)
		return
	}

	r, err := redis.Ints(c.Do("MGet", "abc", "efg"))
	if err != nil {
		fmt.Println("get abc failed,", err)
		return
	}

	for _, v := range r {
		fmt.Println(v)
	}
}

Hash操作

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

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

	defer c.Close()
	if err != nil {
		fmt.Println(err)
		return
	}
	
	_, err = c.Do("HSet", "books", "abc", 100) // 设置一个hash类型的键值, 并且在其中存放一个键值
	if err != nil {
		fmt.Println(err)
		return
	}

	r, err := redis.Int(c.Do("HGet", "books", "abc")) // 取值
	if err != nil {
		fmt.Println("get abc failed,", err)
		return
	}

	fmt.Println(r)
}

设置过期时间

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

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

	defer c.Close()
	_, err = c.Do("expire", "abc", 10) // 给一个键设置过期时间
	if err != nil {
		fmt.Println(err)
		return
	}
}

LIST操作

package main

import (
	"fmt"
	"github.com/garyburd/redigo/redis"
)

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

	defer c.Close()
	_, err = c.Do("lpush", "book_list", "abc", "ceg", 300)
	if err != nil {
		fmt.Println(err)
		return
	}

	r, err := redis.String(c.Do("lpop", "book_list"))
	if err != nil {
		fmt.Println("get abc failed,", err)
		return
	}

	fmt.Println(r)
}

　　总而言之c.Do(命令,参数...) 然后再将他们转换成不同的类型redis.String()
