节点-红色Dropbox节点

Question

我正在使用节点-红色节点-dropbox，并让我的流工作如下：

1. 通过文件访问检查文件是否存在，如果存在，则上载它。一旦文件被上传，就会得到更改的通知，并获取文件的名称和路径，如果存在，则删除本地文件。下面是我用来调试的测试低点。

​

结果:如果文件存在，该文件将被上载到目录中。然后被删除。一切按计划进行。问题是，当我转到“拖放框中的文件”时，文件的大小只有几个字节，而不是预期的KB或有时是MB。我对类似的问题做了一些研究，发现如下：Laravel Dropbox API v2 - Empty File on Upload

现在我要说的是，我不是一个程序员。我正在进行一个家庭项目，并试图将时间流逝的GIF从本地Rpi移动到dropbox文件夹。

任何帮助都是非常感激的。如果有一个更新，一个黑客，一个解决办法，我会拿走任何东西。

下面是我的测试流程：

Answer 1

我更改了流并添加了readdir以创建目录中所有文件的列表。

​

​

readdir的设置如下：

​

​

我基本上指向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属性来一次上传它们。这就是Dropbox节点所需要的。现在效果很好。
