图片预览image-output

node-red-contrib-image-output

这个node可以直接在NR里预览图片,在调试涉及图片的流程时非常方便。
本地和外网的图都能使用,只要传入二进制缓冲模块就好。
再点击一下图片,图片就会消失。

非常好的推荐,调试图片链接一目了然。只是这示例有些问题 :smile:

有什么节点可以实现在nr的可视化界面显示mqtt上传的图片的

你红框那个地方,msg后面要有负载路径的,要不,节点都不知道读取什么东西

好的,多谢大佬:pray::pray:

大佬我显示Error: Invalid property expression: zero-length",该怎么配置

检查一下,那个图片的长度设置为零了

导入流的时候提示Error: 输入的不是JSON数组是怎么回事呀
