import 時間 redis println get() host turn get tcp 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)
}
}過期時間：
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
}
}連接池：
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()
