Django 利用zipstream压缩下载多文件夹

1、安装 zipstream

pip install zipstream

2、简单封装下zipstream

# -*- coding: UTF-8 -*-
import zipfile
import os
import zipstream
class ZipUtilities:
    zip_file = None

    def __init__(self):
        self.zip_file = zipstream.ZipFile(mode='w', compression=zipstream.ZIP_DEFLATED)

    def toZip(self, file, name):
        if os.path.isfile(file):
            self.zip_file.write(file, arcname=os.path.basename(file))
        else:
            self.addFolderToZip(file, name)

    def addFolderToZip(self, folder, name):
        for file in os.listdir(folder):
            full_path = os.path.join(folder, file)
            if os.path.isfile(full_path):
                self.zip_file.write(full_path, arcname=os.path.join(name, os.path.basename(full_path)))
            elif os.path.isdir(full_path):
                self.addFolderToZip(full_path, os.path.join(name, os.path.basename(full_path)))

    def close(self):
        if self.zip_file:
            self.zip_file.close()

3、views.py 使用

utilities = ZipUtilities()
for file_obj in file_objs:
   tmp_dl_path = os.path.join(path_to, filename)
   utilities.toZip(tmp_dl_path, filename)
#utilities.close()
response = StreamingHttpResponse(utilities.zip_file, content_type='application/zip')
response['Content-Disposition'] = 'attachment;filename="{0}"'.format("下载.zip")
return response
