Je veux écrire un programme qui envoie un courrier électronique en utilisant Python smtplib . Je cherchai dans le document et les RFCs, mais n'a pas pu trouver tout ce qui concerne les pièces jointes. Ainsi, je suis sûr qu'il ya un concept de niveau supérieur que je suis absent sur. Peut-indice de quelqu'un me sur la façon dont les pièces jointes travaillent dans SMTP?

Voici un exemple d'un message avec une pièce jointe PDF, un texte « corps » et l'envoi via Gmail.
# Import smtplib for the actual sending function
import smtplib
# For guessing MIME type
import mimetypes
# Import the email modules we'll need
import email
import email.mime.application
# Create a text/plain message
msg = email.mime.Multipart.MIMEMultipart()
msg['Subject'] = 'Greetings'
msg['From'] = 'xyz@gmail.com'
msg['To'] = 'abc@gmail.com'
# The main body is just another attachment
body = email.mime.Text.MIMEText("""Hello, how are you? I am fine.
This is a rather nice letter, don't you think?""")
msg.attach(body)
# PDF attachment
filename='simple-table.pdf'
fp=open(filename,'rb')
att = email.mime.application.MIMEApplication(fp.read(),_subtype="pdf")
fp.close()
att.add_header('Content-Disposition','attachment',filename=filename)
msg.attach(att)
# send via Gmail server
# NOTE: my ISP, Centurylink, seems to be automatically rewriting
# port 25 packets to be port 587 and it is trashing port 587 packets.
# So, I use the default port 25, but I authenticate.
s = smtplib.SMTP('smtp.gmail.com')
s.starttls()
s.login('xyz@gmail.com','xyzpassword')
s.sendmail('xyz@gmail.com',['xyz@gmail.com'], msg.as_string())
s.quit()
Voici un exemple que je Snipped sur une demande de travail que nous avons fait. Il crée un e-mail HTML avec une pièce jointe Excel.
import smtplib,email,email.encoders,email.mime.text,email.mime.base
smtpserver = 'localhost'
to = ['email@somewhere.com']
fromAddr = 'automated@hi.com'
subject = "my subject"
# create html email
html = '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" '
html +='"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml">'
html +='<body style="font-size:12px;font-family:Verdana"><p>...</p>'
html += "</body></html>"
emailMsg = email.MIMEMultipart.MIMEMultipart('alternative')
emailMsg['Subject'] = subject
emailMsg['From'] = fromAddr
emailMsg['To'] = ', '.join(to)
emailMsg['Cc'] = ", ".join(cc)
emailMsg.attach(email.mime.text.MIMEText(html,'html'))
# now attach the file
fileMsg = email.mime.base.MIMEBase('application','vnd.ms-excel')
fileMsg.set_payload(file('exelFile.xls').read())
email.encoders.encode_base64(fileMsg)
fileMsg.add_header('Content-Disposition','attachment;filename=anExcelFile.xls')
emailMsg.attach(fileMsg)
# send email
server = smtplib.SMTP(smtpserver)
server.sendmail(fromAddr,to,emailMsg.as_string())
server.quit()
Eh bien, les pièces jointes ne sont pas traités en aucune façon spéciale, ils sont « justes » les feuilles de l'arbre objet du message. Vous pouvez trouver les réponses à toutes les questions concernant mesasges conforme MIME dans cette section de la documentation sur le email .
D'une manière générale, tout type de fixation (lire: des données binaires brutes) peuvent être représentés à l'aide de base64
(Ou similaire) Content-Transfer-Encoding.
Voici comment envoyer des e-mails avec des pièces jointes de fichiers zip et utf-8 sujet + corps encodée.
Il n'a pas été facile à comprendre cela, en raison du manque de documentation et des échantillons pour ce cas particulier.
Les caractères non-ascii dans replyto doit être codé avec, par exemple, ISO-8859-1. Il existe probablement une fonction qui peut le faire.
