list（数组）
队列，列表的子成员类型为string
lpush key value
rpush key value
linsert key after|before 指定元素 value
lindex key index
lrange key start stop
lset key index value
lrem key count value
（1）添加子成员
# 在左侧(前)添加一条或多条数据
lpush key value1 value2 ...
# 在右侧(后)添加一条或多条数据
rpush key value1 value2 ...
# 在指定元素的左边(前)/右边（后）插入一个或多个数据
linsert key before 指定元素 value1 value2 ....
linsert key after 指定元素 value1 value2 ....
从键为brother的列表左侧添加一个或多个数据liubei、guanyu、zhangfei
lpush brother liubei
# [liubei]
lpush brother guanyu zhangfei xiaoming
# [xiaoming,zhangfei,guanyu,liubei]
从键为brother的列表右侧添加一个或多个数据，xiaohong,xiaobai,xiaohui
rpush brother xiaohong
# [xiaoming,zhangfei,guanyu,liubei,xiaohong]
rpush brother xiaobai xiaohui
# [xiaoming,zhangfei,guanyu,liubei,xiaohong,xiaobai,xiaohui]
从key=brother的xiaohong的列表位置左侧添加一个数据，xiaoA,xiaoB
linsert brother before xiaohong xiaoA
# [xiaoming,zhangfei,guanyu,liubei,xiaoA,xiaohong,xiaobai,xiaohui]
linsert brother before xiaohong xiaoB
# [xiaoming,zhangfei,guanyu,liubei,xiaoA,xiaoB,xiaohong,xiaobai,xiaohui]
从key=brother，key=xiaohong的列表位置右侧添加一个数据，xiaoC,xiaoD
linsert brother after xiaohong xiaoC
# [xiaoming,zhangfei,guanyu,liubei,xiaoA,xiaohong,xiaoC,xiaobai,xiaohui]
linsert brother after xiaohong xiaoD
# [xiaoming,zhangfei,guanyu,liubei,xiaoA,xiaohong,xiaoD,xiaoC,xiaobai,xiaohui]
注意：当列表如果存在多个成员值一致的情况下，默认只识别第一个。
127.0.0.1:6379> linsert brother before xiaoA xiaohong
# [xiaoming,zhangfei,guanyu,liubei,xiaohong,xiaoA,xiaohong,xiaoD,xiaoC,xiaobai,xiaohui]
127.0.0.1:6379> linsert brother before xiaohong xiaoE
# [xiaoming,zhangfei,guanyu,liubei,xiaoE,xiaohong,xiaoA,xiaohong,xiaoD,xiaoC,xiaobai,xiaohui]
127.0.0.1:6379> linsert brother after xiaohong xiaoF
# [xiaoming,zhangfei,guanyu,liubei,xiaoE,xiaohong,xiaoF,xiaoA,xiaohong,xiaoD,xiaoC,xiaobai,xiaohui]
（2）基于索引获取列表成员
根据指定的索引(下标)获取成员的值，负数下标从右边-1开始，逐个递减
lindex key index
获取brother下标为2以及-2的成员
del brother
lpush brother guanyu zhangfei xiaoming
lindex brother 2
# "guanyu"
lindex brother -2
# "zhangfei"
（3）获取列表的切片
闭区间[包括stop]
lrange key start stop
操作：
del brother
rpush brother liubei guanyu zhangfei xiaoming xaiohong
# 获取btother的全部成员
lrange brother 0 -1
# 获取brother的前2个成员
lrange brother 0 1
# 获取brother的后2个成员
lrange brother -2 -1
（4）获取列表的长度
llen key
获取brother列表的成员个数
llen brother
（5）按索引设置值
lset key index value
# 注意：
# redis的列表也有索引，从左往右，从0开始，逐一递增，第1个元素下标为0
# 索引可以是负数，表示尾部开始计数，如`-1`表示最后1个元素
修改键为brother的列表中下标为4的元素值为xiaohongmao
lset brother 4 xiaohonghong
（6）删除指定成员
移除并获取列表的第一个成员或最后一个成员
lpop key # 第一个成员出列
rpop key # 最后一个成员出列
获取并移除brother中的第一个成员
lpop brother
# 开发中往往使用rpush和lpop实现队列的数据结构->实现入列和出列
lrem key count value
# 注意：
# count表示删除的数量，value表示要删除的成员。该命令默认表示将列表从左侧前count个value的元素移除
# count==0，表示删除列表所有值为value的成员
# count >0，表示删除列表左侧开始的前count个value成员
# count <0，表示删除列表右侧开始的前count个value成员
del brother
rpush brother A B A C A
lrem brother 0 A
["B","C"]
del brother
rpush brother A B A C A
lrem brother -2 A
["A","B","C"]
del brother
rpush brother A B A C A
lrem brother 2 A
["B","C","A"]
