18.15. quopri — Codifica e decodifica dados imprimíveis com aspas em MIME

Código Fonte: Lib/quopri.py

Este módulo realiza codificação e decodificação de transporte imprimida entre aspas, como definido em RFC 1521: “MIME (Multipurpose Internet Mail Extensions) Part One: Mechanisms for Specifying and Describing the Format of Internet Message Bodies”. A codificação imprimida entre aspas é projetada para dados em que há relativamente poucos caracteres não imprimíveis; o esquema de codificação base64 disponível através do módulo base64 é mais compacto se existirem muitos desses caracteres, como no envio de um arquivo gráfico.

quopri.decode(input, output[, header])

Decode the contents of the input file and write the resulting decoded binary data to the output file. input and output must either be file objects or objects that mimic the file object interface. input will be read until input.readline() returns an empty string. If the optional argument 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”.

quopri.encode(input, output, quotetabs)

Encode the contents of the input file and write the resulting quoted-printable data to the output file. input and output must either be file objects or objects that mimic the file object interface. input will be read until input.readline() returns an empty string. quotetabs is a flag which controls whether to encode embedded spaces and tabs; 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.

quopri.decodestring(s[, header])

Like decode(), except that it accepts a source string and returns the corresponding decoded string.

quopri.encodestring(s[, quotetabs])

Like encode(), except that it accepts a source string and returns the corresponding encoded string. quotetabs is optional (defaulting to 0), and is passed straight through to encode().
