python从PDF中提取附件
下载 Pdftk server:https://www.pdflabs.com/tools/pdftk-server/
如果有密码,先把带密码的PDF的转成无密码的PDF
pdftk 有密码.pdf input_pw 密码 output 无密码.pdf
如果不带密码,上一步可以跳过
提取附件(必须不带密码)
pdftk 无密码.pdf unpack_files 解压目录
如果python cmd命令时显示不存在命令,
加入 os.chdir(pdftk的bin目录)
完整代码:
import osdef get_attachment(pdf_path,psd,pdftk_bin_folder):pdf_folder_path
=pdf_path.strip(pdf_path.split("")[-1])tem_pdf_path
=pdf_folder_path+"temp.pdf"decrypt_command
=f"pdftk {pdf_path} input_pw {psd} output {tem_pdf_path}"extract_command
=f"pdftk {tem_pdf_path} unpack_files output {pdf_folder_path}"os.chdir(pdftk_bin_folder)
os.system(decrypt_command)
os.system(extract_command)
if__name__ == "__main__":# pdf_path = r"C:Users86173Desktop estword2-protected.pdf"# psd = "dfcver"
pdf_path = r"C:Users86173Desktop estword无密码1.pdf"
psd = ""
pdftk_bin_folder = r"C:Program Files (x86)PDFtk Serverin"
try:
get_attachment(pdf_path,psd,pdftk_bin_folder)
print("提取成功")
except Exception as e:
print("提取失败")
print(e)
