使用 django 和 HttpResponse 导出 xls 文件供用户下载时出现问题
我目前正在使用 xlwt 创建一个电子表格,并尝试将其导出为 django 中的 HttpResponse 供用户下载。我的代码看起来像这样:
response = HttpResponse(mimetype = "application/vnd.ms-excel")
response['Content-Disposition'] = 'attachment; filename = %s +".xls"' % u'Zinnia_Entries'
work_book.save(response)
return response
这似乎是正确的方法,但我得到了:(
Traceback (most recent call last):
File "C:\dev\workspace-warranty\imcom\imcom\wsgiserver.py", line 1233, in communicate
req.respond()
File "C:\dev\workspace-warranty\imcom\imcom\wsgiserver.py", line 745, in respond
self.server.gateway(self).respond()
File "C:\dev\workspace-warranty\imcom\imcom\wsgiserver.py", line 1927, in respond
response = self.req.server.wsgi_app(self.env, self.start_response)

return self.application(environ, start_response)

response = middleware_method(request, response)
File "C:\dev\workspace-warranty\imcom\imcom\seo_mod\middleware.py", line 33, in process_response
response.content = strip_spaces_between_tags(response.content.strip())

return func(*args, **kwargs)
File "C:\dev\workspace-warranty\3rdparty\django\utils\html.py", line 89, in strip_spaces_between_tags
return re.sub(r'>\s+<', '><', force_unicode(value))
File "C:\dev\workspace-warranty\3rdparty\django\utils\encoding.py", line 88, in force_unicode
raise DjangoUnicodeDecodeError(s, *e.args)
DjangoUnicodeDecodeError: 'utf8' codec can't decode byte 0xd0 in position 0: invalid continuation byte. You passed in
我省略了其余部分,因为我得到了很长的一行 \xd0\xcf\x11\xe0\xa1\ xb1\x1a\xe1\x00 之类的东西)
你们对可能出现问题的事情有什么想法吗?是因为我的一些写入值如下所示:
work_sheet.write(r,#,information) 其中信息未转换为unicode?
I'm currently creating a spreadsheet using xlwt and trying to export it out as an HttpResponse in django for a user to download. My code looks like this:
response = HttpResponse(mimetype = "application/vnd.ms-excel")
response['Content-Disposition'] = 'attachment; filename = %s +".xls"' % u'Zinnia_Entries'
work_book.save(response)
return response
Which seems to be the right way to do it, but I'm getting a:
Traceback (most recent call last):
File "C:\dev\workspace-warranty\imcom\imcom\wsgiserver.py", line 1233, in communicate
req.respond()
File "C:\dev\workspace-warranty\imcom\imcom\wsgiserver.py", line 745, in respond
self.server.gateway(self).respond()

raise DjangoUnicodeDecodeError(s, *e.args)

(I left off the rest because I get a really long line of this \xd0\xcf\x11\xe0\xa1\xb1\x1a\xe1\x00 kind of stuff)
Do you guys have any ideas on something that could be wrong with this? Is is it because some of my write values look like this:
work_sheet.write(r,#,information) where information isn't cast to unicode?

.xls 周围应该
没有引号,否则输出将是

without quotes around .xls otherwise the output will be
So try changing that.
But also check out this answer. It has a really helpful little function for outputing xls files.

解决了问题。显然有人在其中放入了一些时髦的中间件东西,这些东西是分解、附加和添加等。等等。到文件。当不应该的时候。
无论如何,随着它的消失,文件导出完美。
@Storm - 感谢您的所有帮助!
Solved the problem. Apparently someone had put some funky middleware stuff in that was hacking apart and appending and adding, ect. ect. to the file. When it shouldn't.
Anyway, with it gone the file exports perfectly.
@Storm - Thank you for all the help!
