一.golang中安装Redis
github地址:https://github.com/garyburd/redigo
文档地址:http://godoc.org/github.com/garyburd/redigo/redis
安装:
go get github.com/garyburd/redigo/redis
二.简单连接Redis
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)
}
batch_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)
}
}
过期设置
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()
}
