LPUSH key value [value ...]

自1.0.0起可用。

时间严重年夜度: O(1)

将一切指定值拔出存储在列表头部的职位key。假定key不存在,则在推行推送操作之前将其培植为空列表。当key生涯不是列表的值时,将前往弱点。

可以应用单个敕令挪用来推送多个元素,只需在敕令末尾指定多个参数便可。元素被一个接一个地插出列表头部,从最左边的元素到最左边的元素。是以,例如,该敕令LPUSH mylist a b c将招致网罗c第一个元素,b第二个元素和a第三个元素的列表。

前往值

整数回复:推送操作后列表的长度。

历史

  • >= 2.4:吸收多个value参数。在2.4之前的Redis版本中,可以为每个敕令推送一个值。

例子

redis>  LPUSH mylist "world" (integer) 1 

redis>  LPUSH mylist "hello" (integer) 2 

redis>  LRANGE mylist 0 -1 1) "hello" 2) "world"
