redis
使⽤第三⽅开源的redis库: github.com/garyburd/redigo/redis
import(
“github.com/garyburd/redigo/redis"
)
9. 链接redis
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()
}10. Set 接⼝
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)
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)
}11. Hash表
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)
}11. 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)
}
}11. 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
}
}12. 队列操作
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)
