New submission from Christian Degenkolb <christian+pyt...@degenkolb.net>:
Hi,
the following minimal working example of the problem
from io import BytesIO
from os import read
import email
fp = BytesIO()
with open('mail.eml', 'rb') as f:
filecontent = f.read()
print("type(filecontent)= ", type(filecontent))
fp.write(filecontent)
mailobj = email.message_from_bytes(fp)
produces the following exception
$ python testparser.py
type(filecontent)= <class 'bytes'>
Traceback (most recent call last):
File "testparser.py", line 16, in <module>
mailobj = email.message_from_bytes(fp)
File "/usr/lib/python3.8/email/__init__.py", line 46, in message_from_bytes
return BytesParser(*args, **kws).parsebytes(s)
File "/usr/lib/python3.8/email/parser.py", line 122, in parsebytes
text = text.decode('ASCII', errors='surrogateescape')
AttributeError: '_io.BytesIO' object has no attribute 'decode'
This is a python 3.8.10 on an Ubuntu 20.04 LTS installed from the packages.
The documentation for message_from_bytes
https://docs.python.org/3.10/library/email.parser.html#email.message_from_bytes
mentions bytes-like objects which links to
https://docs.python.org/3.10/glossary.html#term-bytes-like-object and
references object of type byte.
Shouldn't this work with BytesIO()? A'm I missing something?
with regards
Christian
