node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js

一、前期准备

  1. 安装配置node-red环境:
  • centos通过源文件的方式安装node-red
  • nodered-环境搭建及使用
  1. 安装配置redis:
  • centos - docker安装redis
  • Windows10安装redis(图文教程)

Redis支持的数据结构

二、node-red安装redis节点

1.在node-red里面安装redis节点 :

node-red-node-redis
node-red-contrib-redis

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
2. 刷新node-red:

三、node-red操作使用redis节点

3.1. List(列表)类型

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js

3.1.1 List(列表)存储 :redis-out节点

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
  redis-out节点负责向redis中存储数据。无返回值,以字符串类型存储,多次触发存储为链表格式。

method说明

  1. LPUSH:将元素推入列表左端
  2. RPUSH:将元素推入列表右端
  • 当用户调用LPUSH命令或RPUSH命令尝试将元素推入列表的时候,如果给定的列表并不存在,那么命令将自动创建一个空列表,并将元素推入刚刚创建的列表中。
  1. LPUSHX:只会在列表已经存在的情况下,将元素推入列表左端
  2. RPUSHX:只会在列表已经存在的情况下,将元素推入列表右端。
    充当发布者,使用RPUSH、LPUSH或PUBLISH
  • 配置节点:
    (1) server:选择redis实例(可以新建)
    node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
    主要是Name里面填写带端口号的redis服务器地址:IP:端口 (如:127.0.0.1:6379)
    node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
    如果有密码,配置示例如下:
    node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
    (2)Name: 随意命名
    (3)Topic : 为redis中的Key

3.1.2 List(列表)读取 - redis-in节点

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
  redis-in节点负责从redis中读取数据。该节点实时监听redis对应实例的对应的topic的数据,一旦数据有变化,就会有输出返回。

  • 节点配置:
    node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js

method说明

  • BLPOP: 阻塞式左端弹出操作。BLPOP命令是带有阻塞功能的左端弹出操作,它接受任意多个列表以及一个秒级精度的超时时限作为参数。当BLPOP命令成功对某个非空列表执行了弹出操作之后,它将向用户返回一个包含两个元素的数组:数组的第一个元素记录了执行弹出操作的列表,即被弹出元素的来源列表,而数组的第二个元素则是被弹出元素本身。BLPOP命令会按照从左到右的顺序依次检查用户给定的列表,并对最先遇到的非空列表执行左端元素弹出操作。如果BLPOP命令在检查了用户给定的所有列表之后都没有发现可以执行弹出操作的非空列表,那么它将阻塞执行该命令的客户端并开始等待,直到某个给定列表变为非空,又或者等待时间超出给定时限为止。
  • BRPOP:阻塞式右端弹出操作。除了弹出的方向不同之外,其他方面都和BLPOP命令一样。

BLPOP、BRPOP和BRPOPLPUSH是阻塞版本的弹出和推入命令,如果用户给定的所有列表都为空,那么执行命令的客户端将被阻塞,直到给定的阻塞时限到达或者某个给定列表非空为止。

3.2 redis-cmd节点

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js

3.2.1 String(字符串)类型读写

  • 赋值:
    (1)redis-cmd节点的set命令,返回赋值状态
    (2)redis-cmd节点的getset命令,返回实际值
  • 取值:redis-cmd节点的get命令,返回实际值,不存在的key返回null
    node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js
    点我回到目录

3.2.2 Set(集合)类型读写

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js

  • 赋值:redis-cmd节点的sadd命令,返回插入元素个数,已经存在集合中的元素不重复插入
  • redis-cmd节点的sismember命令,判断元素是否存在SET集合中:
    (1)存在,返回1;
    (2)不存在,返回0。

3.2.3 Hash(key-value)类型读写

node-red - 读写操作redis,数据采集,redis,数据库,缓存,node.js

  • 赋值:redis-cmd节点的hmset命令,返回赋值状态
  • 取值:redis-cmd节点的hgetall命令,返回所有key-value

点我回到目录

3.3 redis-lua

  在Redis内部执行lua脚本,将payload数组作为参数发送,并将结果作为payload返回。

  • 选项
    (1)存储:如果要使用SCRIPT LOAD和EVALSHA运行脚本,请设置
    (2)Keys:发送到lua脚本的键数
    (3)脚本:Lua脚本
    (4)有效负载:您需要在发送所有值之前、之后发送所有密钥。

3.4 删除key和监听redis状态

  • redis-cmd的del命令,删除指定可以,成功删除返回1
  • redis instance实例:监听状态
