New submission from Dmitry Jemerov <intelliy...@gmail.com>:
I'm trying to download a file from a site using HTTP authentication. I'm
subclassing FancyURLOpener, returning my credentials from the
prompt_user_passwd() method, and using opener.retrieve() to download the file.
I get the following error:
File "C:/JetBrains/IDEA/build/eap/downandup.py", line 36, in download
opener.retrieve(url, os.path.join(target_path, name))
File "C:\Python31\lib\urllib\request.py", line 1467, in retrieve
fp = self.open(url, data)
File "C:\Python31\lib\urllib\request.py", line 1435, in open
return getattr(self, name)(url)
File "C:\Python31\lib\urllib\request.py", line 1609, in open_http
return self._open_generic_http(http.client.HTTPConnection, url, data)
File "C:\Python31\lib\urllib\request.py", line 1605, in _open_generic_http
response.status, response.reason, response.msg, data)
File "C:\Python31\lib\urllib\request.py", line 1621, in http_error
result = method(url, fp, errcode, errmsg, headers)
File "C:\Python31\lib\urllib\request.py", line 1859, in http_error_401
return getattr(self,name)(url, realm)
File "C:\Python31\lib\urllib\request.py", line 1931, in retry_http_basic_auth
return self.open(newurl)
File "C:\Python31\lib\urllib\request.py", line 1435, in open
return getattr(self, name)(url)
File "C:\Python31\lib\urllib\request.py", line 1609, in open_http
return self._open_generic_http(http.client.HTTPConnection, url, data)
File "C:\Python31\lib\urllib\request.py", line 1571, in _open_generic_http
auth = base64.b64encode(user_passwd).strip()
File "C:\Python31\lib\base64.py", line 56, in b64encode
raise TypeError("expected bytes, not %s" % s.__class__.__name__)
TypeError: expected bytes, not str
The problem happens because _open_generic_http extracts the user password from
the string URL, and passes the string to the b64encode method, which only
accepts bytes and not strings. The problem happens with Python 3.1.1 for me,
but as far as I can see it's still not fixed in the py3k branch as of now.
