quopri
— 编码和解码 MIME 带引号可打印数据
¶
源代码： Lib/quopri.py
This module performs quoted-printable transport encoding and decoding, as defined in
RFC 1521
: “MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies”. The quoted-printable encoding is designed for data where there are relatively few nonprintable characters; the base64 encoding scheme available via the
base64
module is more compact if there are many such characters, as when sending a graphics file.

decode
(

,
header=False
)
¶
Decode the contents of the input file and write the resulting decoded binary data to the output 文件。 input and output 必须为 binary file objects 。若可选自变量 header is present and true, underscore will be decoded as space. This is used to decode “Q”-encoded headers as described in RFC 1522 : “MIME (Multipurpose Internet Mail Extensions) Part Two: Message Header Extensions for Non-ASCII Text”.

¶
Encode the contents of the input file and write the resulting quoted- printable data to the output 文件。 input and output 必须为 binary file objects . quotetabs , a flag which controls whether to encode embedded spaces and tabs must be provideda and when true it encodes such embedded whitespace, and when false it leaves them unencoded. Note that spaces and tabs appearing at the end of lines are always encoded, as per RFC 1521 . header is a flag which controls if spaces are encoded as underscores as per RFC 1522 .
