Dropbox 是一项文件托管服务，将所有传统文件、云内容和网络快捷方式整合到一个位置。 本笔记本介绍了如何从 Dropbox 加载文档。除了文本和 PDF 文件等常见文件外，它还支持 Dropbox Paper 文件。

​
先决条件

  1. 创建 Dropbox 应用。
  2. 授予应用以下范围权限：files.metadata.read 和 files.content.read。
  3. 生成访问令牌：www.dropbox.com/developers/apps/create。
  4. pip install dropbox（PDF 文件类型需要 pip install "unstructured[pdf]"）。

​
指令

`DropboxLoader` 需要您创建一个 Dropbox 应用并生成一个访问令牌。这可以通过 www.dropbox.com/developers/apps/create 完成。您还需要安装 Dropbox Python SDK (pip install dropbox)。 DropboxLoader 可以从 Dropbox 文件路径列表或单个 Dropbox 文件夹路径加载数据。这两个路径都应相对于与访问令牌关联的 Dropbox 账户的根目录。
pip install dropbox
