在Django中返回HttpResponse后删除tmp文件

您可以使用NamedTemporaryFile：

from django.core.files.temp import NamedTemporaryFiledef send_file(request):    newfile = NamedTemporaryFile(suffix='.txt')    # save your data to newfile.name    wrapper = FileWrapper(newfile)    response = HttpResponse(wrapper, content_type=mime_type)    response['Content-Disposition'] = 'attachment; filename=%s' % os.path.basename(modelfile.name)    response['Content-Length'] = os.path.getsize(modelfile.name)    return response

撤消newfile对象后，应删除临时文件。
