redis mget命令

MGET key [key …]

Returns the values of all specified keys.
For every key that does not hold a string value or does not exist, the special
value nil is returned.
Because of this, the operation never fails.


Array reply: list of values at the specified keys.


redis>  SET key1 “Hello”


redis>  SET key2 “World”


redis>  MGET key1 key2 nonexisting

1) "Hello"
2) "World"
