如何使用python函数（WINDOWS）将docx转换为pdf？

Question

我正在开发一个带有python函数的env，用于将docx转换为pdf文件。我用邮递员发送base64。然后我挂载docx文件（一切正常），但是当它将docx文件转换成pdf时，出现了一个错误。我想那是因为我的环境没有办公室？没有办公室我怎么能修好它？谢谢。在

import sys
import os
import comtypes.client
import pythoncom
import uuid
import requests
from docx import Document
import base64
from os import listdir
from os.path import isfile, join
import azure.functions as func

def main(req: func.HttpRequest) -> func.HttpResponse:
  bytesDoc = req.get_json()['base']

  path = '/users/echornet/pruebas/'
  newFile = open(path + 'prueba.docx','wb')
  newFile.write(base64.b64decode(bytesDoc))

  newFile.close()
  wdFormatPDF = 17

  out_file = path + 'prueba.pdf'
  word = comtypes.client.CreateObject('Word.Application')

  doc = word.Documents.Open(newFile)
  doc.SaveAs(out_file, FileFormat=wdFormatPDF)
  doc.Close()

这就是我得到的错误。我得到了从base64创建的docx，但没有转换

你可以试试lib win32com来完成

# -*- encoding: utf-8 -*-
import  os
from win32com import client
#pip instatll win32com
def doc2pdf(doc_name, pdf_name):
    """
    :word to pdf
    :param doc_name word file name
    :param pdf_name to_pdf file name
    """
    try:
        word = client.DispatchEx("Word.Application")
        if os.path.exists(pdf_name):
            os.remove(pdf_name)
        worddoc = word.Documents.Open(doc_name,ReadOnly = 1)
        worddoc.SaveAs(pdf_name, FileFormat = 17)
        worddoc.Close()
        return pdf_name
    except:
        return 1
if __name__=='__main__':
    doc_name = "f:/test.doc"
    ftp_name = "f:/test.pdf"
    doc2pdf(doc_name, ftp_name)
