Negli ultimi giorni ho lavorato per scrivere uno script che analizza i biglietti per Guida generati automaticamente e memorizza il loro contenuto in un database. Durante il test ho riscontrato diverse e-mail che sembrano codificarsi e causare il fallimento dello script. Di seguito è riportato un esempio di uno degli RFC822S:

è il corpo dell'email codificato? E se sì, come dovrei gestirlo decodificandolo?
Soluzione
Il corpo è codificato (contenuto-trasferimento-codifica: base64) che non è la stessa come crittografata.Incollando il primo set di caratteri in un decodificatore online
Q2FzZSBOdW1iZXI6ICAgICAgICAgU0MtMTE4NjU2LTcwMzENClNldmVyaXR5IExldmVsOiAg
viene decodificato come
Case Number: SC-118656-7031
Severity Level:
Python ha biblioteche per decodificare BASE64, ma sarei deluso se IMAPLIB non ha avuto un builtin per semplificarlo.
Altri suggerimenti
È possibile utilizzare email pacchetto per questo.Hai una lista lì, e il primo elemento dell'elenco è una tupla, di cui il secondo elemento è l'intero messaggio e-mail.Diciamo che hai questo oggetto Bytes in una variabile chiamata msg_bytes.È quindi possibile analizzare il messaggio usando:
import email.parser
msg = email.parser.BytesParser().parsebytes(msg_bytes)
È quindi possibile accedere a diverse parti del messaggio (fare riferimento alla documentazione su email.message.Message ):
# get a bytes object containing the base64-decoded message
textbytes = msg.get_payload(decode=True)
# get the content charset
content_charset = msg.get_content_charset()
# decode the text to obtain a string object
text = textbytes.decode(content_charset)
Questo sarà in grado di affrontare la maggior parte, se non tutte le e-mail valide.
