时间复杂度： O(1)

Get the value of key. If the key does not exist the special value nil is returned. An error is returned if the value stored at key is not a string, because GET only handles string values.

返回值

Bulk string reply: the value of key, or nil when key does not exist.

例子

redis> GET nonexisting

(nil)

redis> SET mykey "Hello"

OK

redis> GET mykey

"Hello"
