Dropbox

Dropbox 是一个文件托管服务，它将传统文件、云内容和网页快捷方式集合到一个地方。

本笔记本介绍了如何从 Dropbox 加载文档。除了常见的文本和 PDF 文件外，它还支持 Dropbox Paper 文件。

先决条件

1. 创建一个 Dropbox 应用。

2. 为应用程序授予这些范围权限：files.metadata.read 和 files.content.read。

3. 生成访问令牌：https://www.dropbox.com/developers/apps/create。

4. pip install dropbox（对于 PDF 文件类型，需要 pip install "unstructured[pdf]"）。

指示

DropboxLoader 需要您创建一个 Dropbox 应用并生成访问令牌。这可以从 https://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 帐户的根目录。

pip install dropbox
