I am attempting to piece together a Python client for Fotobilder, the picture management server on Livejournal.
The protocol calls for binary data to be transmitted, and I cannot seem
to be able to do it, because I get this error:
>>> sb.UploadSinglePicture('/home/mbt/IMG_2618.JPG')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "scrapbook.py", line 181, in UploadSinglePicture
{Request['UploadPic.Meta.Filename']: pic_mem})
File "scrapbook.py", line 237, in ComposeMIME
return(self.EncodeMIME(fields, files))
File "scrapbook.py", line 226, in EncodeMIME
body = eol.join(L)
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 0:
ordinal not in range(128)
>>>
When putting the MIME segments (listed line-by-line in a Python list)
together to transmit them. The files are typically JPG or some other
binary format, and as best as I understand the protocol, the binary data
needs to be transmitted directly (this is evidenced by looking at the
tcp-stream of an existing client for uploading files).
It seems that Python thinks it knows better than I do, though. I want
to send this binary data straightaway to the server. :-)
This is a hex dump of what one file looks like being uploaded to the
server (partial; the file is 3.8 MB):

Is there any way to tell Python to ignore the situation and treat the
entire thing as simply a stream of bytes? I cannot seem to find one,
though I have found a great many posts on this mailing list regarding
issues in the past. It doesn't look like translating the file to base64
is an option for me.
