发送包含适当MIME类型的多部分电子邮件。
https://docs.python.org/2/library/email- examples.html
所以可能是这样的（我测试过）：
import smtplib
import mimetypes
from email.mime.multipart import MIMEMultipart
from email import encoders
from email.message import Message
from email.mime.audio import MIMEAudio
from email.mime.base import MIMEBase
from email.mime.image import MIMEImage
from email.mime.text import MIMEText
emailfrom = "sender@example.com"
emailto = "destination@example.com"
fileToSend = "hi.csv"
username = "user"
password = "password"
msg = MIMEMultipart()
msg["From"] = emailfrom
msg["To"] = emailto
msg["Subject"] = "help I cannot send an attachment to save my life"
msg.preamble = "help I cannot send an attachment to save my life"
ctype, encoding = mimetypes.guess_type(fileToSend)
if ctype is None or encoding is not None:
ctype = "application/octet-stream"
maintype, subtype = ctype.split("/", 1)
if maintype == "text":
fp = open(fileToSend)
# Note: we should handle calculating the charset
attachment = MIMEText(fp.read(), _subtype=subtype)
fp.close()
elif maintype == "image":
fp = open(fileToSend, "rb")
attachment = MIMEImage(fp.read(), _subtype=subtype)
fp.close()
elif maintype == "audio":
fp = open(fileToSend, "rb")
attachment = MIMEAudio(fp.read(), _subtype=subtype)
fp.close()
else:
fp = open(fileToSend, "rb")
attachment = MIMEBase(maintype, subtype)
attachment.set_payload(fp.read())
fp.close()
encoders.encode_base64(attachment)
attachment.add_header("Content-Disposition", "attachment", filename=fileToSend)
msg.attach(attachment)
server = smtplib.SMTP("smtp.gmail.com:587")
server.starttls()
server.login(username,password)
server.sendmail(emailfrom, emailto, msg.as_string())
server.quit()
