下載docxtpl生成的文件與cherrypy

我正在使用docxtpl生成一個word文檔，並想知道如何用戶可以下載此文件一旦生成使用cherrypy，請參閱下面我的代碼。下載docxtpl生成的文件與cherrypy

我想出的唯一解決方案是將其保存到www文件夾並創建一個鏈接到位置，但我相信這可以簡化。

代碼：

import os, os.path 
import random 
import string 
import cherrypy 
from docxtpl import DocxTemplate 
import sys 
from auth import AuthController, require, member_of, name_is 
import socket 

reload(sys) 
sys.setdefaultencoding('utf8') 
cherrypy.config.update({'server.socket_port': 8000}) 
cherrypy.server.socket_host = '0.0.0.0' 
cherrypy.engine.restart() 

class Root(object): 

    _cp_config = { 
     'tools.sessions.on': True, 
     'tools.auth.on': True } 

    @cherrypy.expose() 
    def default(self, **kwargs): 
     print kwargs  
     if kwargs.get('csa_no'): 
#    print kwargs.get('csa_no') 
      tpl=DocxTemplate('csa_tpl.docx')    
      sd = tpl.new_subdoc() 
      p = sd.add_paragraph('This 1st insert') 
      sd2 = tpl.new_subdoc() 
      p = sd2.add_paragraph('This 2nd insert') 
      context1 = { 
        'date': 'jkh', 
        'company_name' : 'Test Footer', 
        'cost' : '10,000',

        'Initial_Contract_Value': '$300,000', 
        'variation_total': '$20,000', 
        'Ammended_Contract_Value': '$320,000', 
        'project_manager': kwargs['project_manager'], 
        'construction_manager': 'Dane Wilson', 
        'date': '30/04/2016',  
       } 
      tpl.render(context1) 
      file_name_with_path = '/var/www/html/csa_documents/' + kwargs['sp'] + '-'+ kwargs['WO'] + '_' + kwargs['site'] + '_-_' + 'CSA' + kwargs['csa_no'] +'.docx' 
      file_name = kwargs['sp'] + '-'+ kwargs['WO'] + '_' + kwargs['site'] + '_-_' + 'CSA' + kwargs['csa_no'] +'.docx' 
      print file_name 
      print file_name_with_path 
      tpl.save(file_name_with_path) 
      return '''

簡短的回答是，基本上你需要寫一些內存流（例如BytesIO），預先設定的HTTP標頭並返回file_generator。您的問題與一個月前詢問的問題幾乎相同，here是我的答案。

我在python3起草了小片段爲您：

from io import BytesIO 

import cherrypy 
from cherrypy.lib import file_generator 

from docxtpl import DocxTemplate 


class GenerateDocx: 
    @cherrypy.expose 
    def build_docx(self, *args, **kwargs): 
     iostream = BytesIO() 

     tpl = DocxTemplate('csa_tpl.docx') 
     ... 
     # build your tpl here 
     ... 
     tpl.get_docx().save(iostream) 

     cherrypy.response.headers['Content-Type'] = (
      # set the correct MIME type for docx 
      'application/vnd.openxmlformats-officedocument' 
      '.wordprocessingml.document' 
     ) 
     cherrypy.response.headers['Content-Disposition'] = (
      'attachment; filename={fname}.docx'.format(
       fname='put your file name here' 
      ) 
     ) 

     iostream.seek(0) 
     return file_generator(iostream)

UPD：我剛剛檢查了the response body gets automatically wrapped with file_generator if the return value of a handler has read() method support

感謝，我得到一個文件，但似乎DOCX，該Content-Disposition似乎設置在zip.please幫助 – Ossama

我設法得到docx使用，cherrypy.response.headers ['Content-Disposition'] =（ 'attachment; filename =「file.docx」' ）但該文件爲空 – Ossama

哦，我錯過了，確定擴展名應該是docx – webKnjaZ
