pip install Spire.PDF

from spire.pdf.common import *
from spire.pdf import *

# 加载 PDF 文档
doc = PdfDocument()
doc.LoadFromFile("input.pdf")

# 创建附件对象，参数为文件名
attachment = PdfAttachment("data.xlsx")

# 将文件数据读入附件
with open("data.xlsx", "rb") as f:
    attachment.Data = f.read()

# 设置附件的描述信息和 MIME 类型
attachment.Description = "源数据表格"
attachment.MimeType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"

# 将附件添加到文档
doc.Attachments.Add(attachment)

# 保存文档
doc.SaveToFile("output.pdf")
doc.Close()

from spire.pdf.common import *
from spire.pdf import *

doc = PdfDocument()
doc.LoadFromFile("input.pdf")
page = doc.Pages[0]

# 读取要附加的文件数据
with open("report.pdf", "rb") as f:
    data = Stream(f.read())

# 创建附件注释
bounds = RectangleF(50.0, 100.0, 15.0, 15.0)
annotation = PdfAttachmentAnnotation(bounds, "report.pdf", data)
annotation.Color = PdfRGBColor(Color.get_Teal())
annotation.Icon = PdfAttachmentIcon.Paperclip
annotation.Text = "附件：详细报告"

# 添加到页面
page.AnnotationsWidget.Add(annotation)

doc.SaveToFile("output.pdf")
doc.Close()

from spire.pdf.common import *
from spire.pdf import *

pdf = PdfDocument()
pdf.LoadFromFile("document_with_attachments.pdf")

# 获取附件集合
collection = pdf.Attachments

if collection.Count > 0:
    for i in range(collection.Count):
        attachment = collection.get_Item(i)
        print(f"文件名: {attachment.FileName}")

# 提取所有附件
for i in range(collection.Count):
