LINDEX key index

自1.0.0起可用。

时间严重年夜度: O(N)其中N是要到达索引处元素的遍历元素的数目。这使得询问列表O(1)的第一个或最后一个元素。

前往index存储在列表中的索引处的元素key。该索引是基于零的,是以0意味着第一个元素,1第二个元素等等。正数索引可用于指定从列表尾部开真个元素。这里-1意味着最后一个元素,-2华夏棋牌意味着倒数第二个元素等等。

当值 key华夏棋牌不是列表时,前往弱点。

前往值

批量字符串回复:请求的元素前往nilindex超出规模。

例子

redis>  LPUSH mylist "World" (integer) 1 

redis>  LPUSH mylist "Hello" (integer) 2 

redis>  LINDEX mylist 0 "Hello" 

redis>  LINDEX mylist -1 "World" 

redis>  LINDEX mylist 3 (nil)
