Python tornado encoding exception

I receive files by @tornado.web.stream_request_body decorator and save it. But with one file if I try to download it, i receive exception:

'latin-1' codec can't encode characters in position 42-47: ordinal not in range(256)

in line self.flush() of tornado handler.

I see that data contain part as a \x00word/_rels/document.xml.relsPK\x01\x02-\ (b"some data [this part]") Maybe that's why an error occurs? How to fix it?

Solution

  • I fix problem. urlencode name of file in Content-Disposition header:

    self.set_header('Content-Disposition', 
    'attachment; filename=' + urllib.parse.quote(file_name, safe=""))
