Dropbox
Dropbox 是一種檔案託管服務，它將所有傳統檔案、雲端內容和網路捷徑集中在一個地方。
本筆記本涵蓋如何從 Dropbox 載入文件。除了文字和 PDF 檔案等常見檔案外，它還支援 Dropbox Paper 檔案。
先決條件
- 建立一個 Dropbox 應用程式。
- 授予應用程式以下範圍權限：
files.metadata.read和files.content.read。 - 產生存取權杖：https://www.dropbox.com/developers/apps/create。
pip install dropbox(PDF 檔案類型需要pip install "unstructured[pdf]")。
說明
`DropboxLoader`` 要求您建立 Dropbox 應用程式並產生存取權杖。 可以從 https://www.dropbox.com/developers/apps/create 完成。 您還需要安裝 Dropbox Python SDK (pip install dropbox)。
DropboxLoader 可以從 Dropbox 檔案路徑清單或單個 Dropbox 資料夾路徑載入資料。 兩個路徑都應該相對於連結到存取權杖的 Dropbox 帳戶的根目錄。
