email.parser.BytesParser

class email.parser.BytesParser(_class=email.message.Message, *, policy=policy.compat32)

This class is exactly parallel to Parser, but handles bytes input. The _class and strict arguments are interpreted in the same way as for the Parser constructor.

If policy is specified (it must be an instance of a policy class) use the rules it specifies to update the representation of the message. If policy is not set, use the compat32 policy, which maintains backward compatibility with the Python 3.2 version of the email package. For more information see the policy documentation.

parse(fp, headersonly=False)

Read all the data from the binary file-like object fp, parse the resulting bytes, and return the message object. fp must support both the readline() and the read() methods on file-like objects.

The bytes contained in fp must be formatted as a block of RFC 2822 style headers and header continuation lines, optionally preceded by an envelope header. The header block is terminated either by the end of the data or by a blank line. Following the header block is the body of the message (which may contain MIME-encoded subparts, including subparts with a Content-Transfer-Encoding of 8bit.

Optional headersonly is a flag specifying whether to stop parsing after reading the headers or not. The default is False, meaning it parses the entire contents of the file.

parsebytes(bytes, headersonly=False)

Similar to the parse() method, except it takes a byte string object instead of a file-like object. Calling this method on a byte string is exactly equivalent to wrapping text in a BytesIO instance first and calling parse().

Optional headersonly is as with the parse() method.
