英文:
go redis HMSet fail
问题
当我在Go中使用redis hmset时，我遇到了以下问题，为什么会这样呢？
ERR wrong number of arguments for 'hset' command
导致值没有存储在redis中？
我参考了redis书籍，为什么会出现这个问题？
func (r *ArticleRepo) PostArticle(user, title, link string) string {
articleId := strconv.Itoa(int(r.Conn.Incr("article:").Val()))
voted := "voted:" + articleId
r.Conn.SAdd(voted, user)
r.Conn.Expire(voted, common.OneWeekInSeconds*time.Second)
now := time.Now().Unix()
article := "article:" + articleId
_, err := r.Conn.HMSet(article, map[string]interface{}{
"title": title,
"link": link,
"poster": user,
"time": now,
"votes": 1,
}).Result()
if err != nil {
fmt.Println(err)
}
r.Conn.ZAdd("score:", &redis.Z{Score: float64(now + common.VoteScore), Member: article})
r.Conn.ZAdd("time:", &redis.Z{Score: float64(now), Member: article})
return articleId
}

When I use redis hmset in Go I get the following problem, why is it?
ERR wrong number of arguments for 'hset' command
Resulting in values not being stored in redis ?
I'm referring to the redis book, why is this a problem ?
func (r *ArticleRepo) PostArticle(user, title, link string) string {
articleId := strconv.Itoa(int(r.Conn.Incr("article:").Val()))
voted := "voted:" + articleId
r.Conn.SAdd(voted, user)
r.Conn.Expire(voted, common.OneWeekInSeconds*time.Second)
now := time.Now().Unix()
article := "article:" + articleId
_, err := r.Conn.HMSet(article, map[string]interface{}{
"title": title,
"link": link,
"poster": user,
"time": now,
"votes": 1,
}).Result()
if err != nil {
fmt.Println(err)
}
r.Conn.ZAdd("score:", &redis.Z{Score: float64(now + common.VoteScore), Member: article})
r.Conn.ZAdd("time:", &redis.Z{Score: float64(now), Member: article})
return articleId
}

你可以在Go中使用hset代替hmset，类似这样的方式：
_, err := r.Conn.Do("hset", article, map[string]interface{}{
"title": title,
"link": link,
"poster": user,
"time": now,
"votes": 1,
}).Result()
英文:
You can use hset instead of hmset with something like this in Go:
_, err := r.Conn.Do("hset", article, map[string]interface{}{
"title": title,
"link": link,
"poster": user,
"time": now,
"votes": 1,
}).Result()
