go - 错误 'zadd'命令的参数数目错误

Question

我发现此错误:

ERR wrong number of arguments for 'zadd' command in golang.

这是我的代码:

defaultPriority:type String
mb.MessageID:type string
mb.EndpointID: type string

    _, err = mbDal.redisClient.ZAdd(mb.EndpointID, redis.Z{Score: defaultPriority, Member: mb.MessageID})
        if err != nil {
            return fmt.Errorf("failed to add mailbox id %s in redis; error %v", mb.MessageID, err)
        }

如何解决此错误消息？

Answer 1

zadd is used in go-redis/redis ，是defined here

// Redis `ZADD key score member [score member ...]` command.
func (c cmdable) ZAdd(key string, members ...*Z) *IntCmd {

仔细检查您的 go.mod依赖关系列表。
10个月前，在go-redis v7(而不是当前的v8)中， signature for that function was:

 func (c *cmdable) ZAdd(key string, members ...Z) *IntCmd {

它使用Z代替(今天)* Z。

就您而言，您应该通过:

&redis.Z{Score: defaultPriority, Member: mb.MessageID}
