我对 Django 有点陌生,所以请多多包涵。
我从这里使用 zipstream并有一个 Django 视图,它返回所有文件附件的 zip 文件,这些文件附件都托管在 Amazon S3 上。但是当我下载 zip 文件时,它们都被损坏了,也就是说,我无法打开它们。我尝试过验证文件,unzip -t
但错误不是很有帮助。
file_paths = [fa.file.url for fa in file_attachments.all()]
zf = zipstream.ZipFile(mode='w', compression=zipstream.ZIP_DEFLATED)
zip_subdir = "Attachments-%s" % (request_id)
for file_path in file_paths:
file_dir, file_name = os.path.split(file_path)
zf.writestr(file_name, urllib.urlopen(file_path).read())
zip_filename = "%s.zip" % (zip_subdir)
response = StreamingHttpResponse(zf, mimetype='application/zip')
response['Content-Disposition'] = \
'attachment; filename={}'.format(zip_filename)
return response
有任何想法吗?
解决了。
s = StringIO.StringIO()
with zipstream.ZipFile(s, mode='w', compression=zipstream.ZIP_DEFLATED) as zf:
#could fail on url open.
for file_path in file_paths:
file_dir, file_name = os.path.split(file_path)
try:
file_contents = urllib.urlopen(file_path).read()
zf.writestr(file_name, file_contents)
except IOError: #connection cannot be made
logging.error()
response = StreamingHttpResponse(s.getvalue(), mimetype='application/octet-stream')
response['Content-Disposition'] = \
'attachment; filename={}'.format("%s" % (request_id))
return response
