package mainimport ( "fmt" "github.com/go-redis/redis")func main() { client := redis.NewClient(&redis.Options{ Addr: "127.0.0.1:6380", Password: "", DB: 0, }) ok1, err1 := client.HSet("key", "field1", "value1").Result() fmt.Printf("ok1=%v err1=%v\n", ok1, err1) ok2, err2 := client.HSet("key", "field2", "value2").Result() fmt.Printf("ok2=%v err2=%v\n", ok2, err2) ok3, err3 := client.HSet("key", "field3", "value3").Result() fmt.Printf("ok3=%v err3=%v\n", ok3, err3) value, err := client.HGet("key", "field2").Result() fmt.Printf("value of field2=%v err=%v\n", value, err) reply, err_hdel := client.HDel("key", "field2").Result() fmt.Printf("reply=%d err_del=%v\n", reply, err_hdel) values, err_hgetall := client.HGetAll("key").Result() fmt.Printf("all values=%v err_hgetall=%v\n", values, err_hgetall)}
输出：
ok1=true err1=<nil>ok2=true err2=<nil>ok3=true err3=<nil>value of field2=value2 err=<nil>reply=1 err_del=<nil>all values=map[field1:value1 field3:value3] err_hgetall=<nil>
如果key已经存在并且value的类型不是哈希表，则报如下错误：
ok1=false err1=WRONGTYPE Operation against a key holding the wrong kind of valueok2=false err2=WRONGTYPE Operation against a key holding the wrong kind of valueok3=false err3=WRONGTYPE Operation against a key holding the wrong kind of valuevalue of field2= err=WRONGTYPE Operation against a key holding the wrong kind of valuereply=0 err_del=WRONGTYPE Operation against a key holding the wrong kind of valueall values=map[] err_hgetall=WRONGTYPE Operation against a key holding the wrong kind of value
