HSTRLEN key field

自3.2.0起可用。

时间复杂度： O（1）

返回与相关联的值的字符串长度field在存储在散列key。如果key或者field不存在，则返回0。

返回值

整数回复：与哈希关联的值的字符串长度field，或者当field哈希key中不存在或根本不存在时为零。

例子

redis> HMSET myhash f1 HelloWorld f2 99 f3 -256 "OK"

redis> HSTRLEN myhash f1 (integer) 10

redis> HSTRLEN myhash f2 (integer) 2

redis> HSTRLEN myhash f3 (integer) 4
