需要先安装 redigo

Go语言Redis客户端的简单示例
为了和redis建立连接,需要创建一个redis.Pool的对象
func newPool() *redis.Pool {
return &redis.Pool{
MaxIdle: 10,
MaxActive: 12000,
Dial: func() (redis.Conn, error) {
c, err := redis.Dial("tcp", ":6379")
if err != nil {
panic(err)
}
return c, err
},
}
}
如果想测试是否连接成功，可以使用 PING 命令
func ping(c redis.Conn) error {
pong, err := c.Do("PING")
if err != nil {
return err
}
s, err := redis.String(pong, err)
if err != nil {
return err
}
fmt.Printf("PING Response = %s\n", s)
return nil
}
func set(c redis.Conn) error {
_, err := c.Do("SET", "Favorite Movie", "Repo Man")
if err != nil {
return err
}
_, err = c.Do("SET", "Release Year", 1984)
if err != nil {
return err
}
return nil
}
func get(c redis.Conn) error {
key := "Favorite Movie"
s, err := redis.String(c.Do("GET", key))
if err != nil {
return err
}
fmt.Printf("%s = %s\n", key, s)
key = "Release Year"
i, err := redis.Int(c.Do("GET", key))
if err != nil {
return err
}
fmt.Printf("%s = %d\n", key, i)
key = "Nonexistent Key"
s, err = redis.String(c.Do("GET", key))
if err == redis.ErrNil {
fmt.Printf("%s does not exist\n", key)
} else if err != nil {
return err
} else {
fmt.Printf("%s = %s\n", key, s)
}
return nil
}
func setStruct(c redis.Conn) error {
const objectPrefix string = "user:"
user := User{
Username: "coderminer.com",
MobileID: "12345678941",
Email: "[email protected]",
FirstName: "coderminer.com",

json, err := json.Marshal(user)
