如何将 pdf 对象从 Databricks 发送到 Sharepoint？

Question

简介：我有一个 Databricks 笔记本，我在其中根据一些数据创建了一个 pdf 文件。为了生成文件，我使用 fpdf 库：

from fpdf import FPDF, HTMLMixin

感谢图书馆，我生成了一个类型为：<__main__.HTML2PDF at 0x7f3b73720fd0> 的 pdf 文件。我现在的目标是将此 pdf 发送到共享点文件夹。为此，我使用了以下代码行：

from office365.runtime.auth.user_credential import UserCredential
from office365.sharepoint.client_context import ClientContext
from office365.sharepoint.files.file import File

# paths
sharepoint_site = "MySharepointSite" 
sharepoint_folder = "Shared Documents/General/PDFs/" 
sharepoint_user = "aaa@bbb.onmicrosoft.com" 
sharepoint_user_pw = "xyz" 
sharepoint_folder = sharepoint_folder.strip("/")

# set environment variables
SITE_URL = f"https://sharepoint.com/sites/{sharepoint_site}"
RELATIVE_URL = f"/sites/{sharepoint_site}/{sharepoint_folder}"

# connect to sharepoint
ctx = ClientContext(SITE_URL).with_credentials(UserCredential(sharepoint_user, sharepoint_user_pw))
web = ctx.web
ctx.load(web).execute_query()

# Generate PDF
pdf = generate_pdf(ctx, row['ServerRelativeUrl'])

# HERE IS MY ISSUE!
ctx.web.get_folder_by_server_relative_url(sharepoint_folder).upload_file('test.pdf', pdf).execute_query()

问题：当我到达最后一行时，我收到以下错误消息：

TypeError: Object of type HTML2PDF is not JSON serializable

我相信 pdf 对象不能序列化为 JSON 因此我被卡住了，我不知道如何将 PDF 发送到共享点。

问题：您能否建议一种巧妙而优雅的方法来实现我的目标，即将 pdf 文件发送到共享点请问？

Answer 1

我通过将 pdf 保存为字符串，然后对其进行编码并最终将其推送到共享点来解决这个问题：

pdf_binary = pdf.output(dest='S').encode("latin1")
ctx.web.get_folder_by_server_relative_url(sharepoint_folder).upload_file("test.pdf", pdf_binary).execute_query()

注意：如果还是不行，换个编码类型试试
