连接数据库
conn, _ := redis.Dial("tcp", ":6379")
defer conn.Close()
conn.Do("set", "key", "value")
- 先通过
send()方法将命令添加到缓冲区，再通过flush()方法执行命令
conn.Send("set", "key", "value")
conn.Flush()
- 先通过
Send()方法将命令添加到缓冲区，再通过Flush()方法执行命令，最后通过Receive()方法获取返回值
conn.Send("get", "key")
conn.Flush()
res, err := conn.Receive()
将查询到的结果强制类型转换
转换为string类型
res, err := redis.String(conn.Do("get", "key"))
转换为bool类型
res, err := redis.Bool(conn.Do("get", "key"))
转换为int类型
res, err := redis.Int(conn.Do("get", "key"))
取出字节流
- 取出多种数据类型的数据
- 先去除字节流数据，再扫描数据的数据类型
res, err := redis.Values(conn.Do("mget", "key1", "key2"))
var key1 string
var key2 int
redis.Scan(res, &key1, &key2)
