redis（包括连接池）

conn：

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()
}

hset：

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("HSet", "books", "abc", 100)
if err != nil {
fmt.Println(err)
return
}

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

fmt.Println(r)
}

list：

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)
}

set：

package main

import (
"fmt"

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

func main() {
var p *int
var a int
p = &a
*p = 0

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

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

fmt.Println(r)
}

批量 set：

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)
}
}

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

连接池：

package main

import (
"fmt"

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

var pool *redis.Pool

func init() {
pool = &redis.Pool{
MaxIdle:     16,
MaxActive:   0,
IdleTimeout: 300,
Dial: func() (redis.Conn, error) {
return redis.Dial("tcp", "localhost:6379")
},
}
}

func main() {

c := pool.Get()
defer c.Close()

_, err := c.Do("Set", "abc", 100)
if err != nil {
fmt.Println(err)
return
}

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

fmt.Println(r)
pool.Close()
}
