本人是个编程小白,各种编程语言基本上都是零基础。想要什么功能也都是百度伺候。当我发现node-red之后发现这个是最适合我们这些小白使用。流程一目了然。但是之前使用时没有弄明白nodered的信息在各个节点之间是怎么传递的,走了很多弯路。等用了一段时间之后发现nodered的信息流真的很好用。所以在这里想把这个机制给新入门的玩家解释一下,能省很多弯路。
一、信息在节点之间传递:
       一开始我以为,在两个节点之间传递的只能是msg.payload。像这样:
1.png
      其实我们可以这样:在两个节点之间传送多个信息:比如同时传递msg.payload    msg.name1   msg.name2等多个信息。
      如图:我们可以用change节点,录入多个信息:
2.png
       这时候,我们把debug节点中的输出选为完整信息:
3.png
       然后我们保存并部署之后,就能把所有的信息都显示出来:
4.png
      或者我们在debug中的输出,填写:msg.name1
5.png
       就能在调试中只看到msg.name1的信息:
6.png
       实际应用:比如,我们想比较name1和name2的大小,可以用switch这么写:
7.png
        还有其他很多的节点都是这样使用的。

二、传递的信息类型:我们在change节点更改信息的时候可以选择很多种类:                8.png
文字列是我们常用的,没特殊需求直接用这个就可以,数字是当我们需要比较大小或者进行运算的时候要用到。布尔值就是true和false。时间戳我们都知道了。json可以录入键值对,或者数组,如图,用[]括起来就是数组。
9.png
表达式和环境变量没用到过还不知道有什么用。希望有大大给补充下。

我们再说说使用funtion节点,实现我们需要的一些功能。
说白了,funtion就是一个js程序或者函数。有时候我们有些需求没找到合适的节点处理,可能就会用到funtion,
1.png
这个就是把几个字符串合并在一起。我们也可以进行四则运算。
2.png
这个是用来处理信息流的,从一段文本列:“05月24日 10:[email protected]今日第4笔收款, 共计¥100.00”。中找出合计多少钱,并且判断这条信息是不是当天收到的。

三、数组的使用,       有时候我们处理数据的时候会出现数组,例如
1.png
这个节点是把某个文件夹下的文件夹和文件名全部列出来,输出的就是一个数组。
2.png
比如,这个就输出了包含21个文件名的数组。
我们可以用split节点将其挨个输出,
3.png
而且最重要的是,每一条信息中除了payload被拆分了之外,其他的比如name1,name2等信息都被保存下来了。

最后,以我写的一个用于归档下载后的电影和美剧的应用。几乎每一个节点都写了备注,新手可以参考学习。
