You must configure allthingsusing this node. Use a differentsetupnode for eachtypein your flows. It is up to you how you organize yourtypes. We recommended you base them on the platforms you use -- in other words, based on how the devices connect into and out of Node-RED. There are ...

我正在使用Node Red实现一个web服务,并且正在绞尽脑汁将base64字符串转换为字节数组( uint8array ),或者将buffer转换为uint8array。我需要将响应的图像传递到需要uint8array基础图像的web服务中。 有很多使用atob和btoa的答案,但是节点red不支持它。 下面是我需要转换的输出缓冲区格式 ? : function toArrayBuffer...

当chunk是一个Buffer,Uint8Array或者string时,chunk数据将会被添加到内部队列,等待被消费。传递chunk为null值表明已经到流的结束了,不再有数据写入。 当Readable操作在暂停模式,由readable.push()进的数据可以通过readable.read()方法读出来,在`redable`事件触发后。 当Redable操作在流动模式,由readable.push()进的...
我正在使用Node Red实现一个web服务,并且正在绞尽脑汁将base64字符串转换为字节数组( uint8array ),或者将buffer转换为uint8array。 我的node-red流的一个"node“将图像作为缓冲区或base64字符串输出。我需要将响应的图像传递到需要uint8array基础图像的web服务中。
可以通过这样的代码来对数据加工read.pipe(red).pipe(bigger).pipe(write),把数据改成红色加大,代码清晰,每一个功能都很形象而且解耦得很好。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 varrs=Readable()varc=1;rs._read=function(){rs.push(String(c++))if(c>100)rs.push(null)}varts=Transfor...
