dropbox-api - Node-Red Dropbox 节点

问题描述

我正在使用 node-red-node-dropbox 并让我的流程执行以下操作：

  1. 使用文件访问检查文件是否存在，如果存在，请上传。
  2. 文件上传后，收到更改通知，获取名称和路径，并删除本地文件（如果存在）。下面是我用来调试的测试低点。 在此处输入图像描述

结果：如果文件存在，则将文件上传到目录。然后被删除。所有工作都按计划进行。问题是当我转到投递箱上的文件时，该文件的大小只有几个字节，而不是预期的 KB 或有时 MB。我对类似问题做了一些研究，发现如下： Laravel Dropbox API v2 - Empty File on Upload

现在我要说，我不是程序员。我正在做一个家庭项目，并试图将延时 GIF 从我的本地 Rpi 移动到 Dropbox 文件夹。

任何帮助都非常感谢。如果有更新、破解、解决方法，我会采取任何措施。

这是我的测试流程：

解决方案

我更改了流程并添加了 readdir 以创建目录中所有文件的列表。

更新流程

readdir 的设置是：

读取目录设置

我基本上指向我所有文件所在的目录，并通过将它们设置为有效负载的 msg.filename 属性一次上传一个。这就是 Dropbox 节点所需要的。现在效果很好。
