我有问题理解如何使用Python电子邮件附件。我已经成功地通过smtplib电子邮件发送了简单的消息。有人能解释一下如何在电子邮件中发送附件吗?我知道网上还有其他的帖子,但作为一个Python初学者,我发现它们很难理解。
当前回答
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage
from email.mime.text import MIMEText
import smtplib
msg = MIMEMultipart()
password = "password"
msg['From'] = "from_address"
msg['To'] = "to_address"
msg['Subject'] = "Attached Photo"
msg.attach(MIMEImage(file("abc.jpg").read()))
file = "file path"
fp = open(file, 'rb')
img = MIMEImage(fp.read())
fp.close()
msg.attach(img)
server = smtplib.SMTP('smtp.gmail.com: 587')
server.starttls()
server.login(msg['From'], password)
server.sendmail(msg['From'], msg['To'], msg.as_string())
server.quit()

python 3的另一种方法(如果有人正在搜索):
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
fromaddr = "sender mail address"
toaddr = "receiver mail address"
msg = MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = toaddr
msg['Subject'] = "SUBJECT OF THE EMAIL"
body = "TEXT YOU WANT TO SEND"
msg.attach(MIMEText(body, 'plain'))
filename = "fileName"
attachment = open("path of file", "rb")
part = MIMEBase('application', 'octet-stream')
part.set_payload((attachment).read())
encoders.encode_base64(part)
part.add_header('Content-Disposition', "attachment; filename= %s" % filename)
msg.attach(part)
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
server.login(fromaddr, "sender mail password")
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()

你也可以在你的电子邮件中指定你想要的附件类型,例如我使用pdf:
def send_email_pdf_figs(path_to_pdf, subject, message, destination, password_path=None):

from socket import gethostname
#import email
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib
import json
server = smtplib.SMTP('smtp.gmail.com', 587)
server.starttls()
with open(password_path) as f:
config = json.load(f)
server.login('me@gmail.com', config['password'])
# Craft message (obj)
msg = MIMEMultipart()
message = f'{message}\nSend from Hostname: {gethostname()}'
msg['Subject'] = subject
msg['From'] = 'me@gmail.com'
msg['To'] = destination
# Insert the text to the msg going by e-mail
msg.attach(MIMEText(message, "plain"))
# Attach the pdf to the msg going by e-mail
with open(path_to_pdf, "rb") as f:
#attach = email.mime.application.MIMEApplication(f.read(),_subtype="pdf")
attach = MIMEApplication(f.read(),_subtype="pdf")
attach.add_header('Content-Disposition','attachment',filename=str(path_to_pdf))
msg.attach(attach)
# send msg
server.send_message(msg)

其他的答案也很好,但我还是想分享一种不同的方法,以防有人正在寻找替代方案。
主要的区别是,使用这种方法,你可以使用HTML/CSS来格式化你的邮件,所以你可以有创意,给你的电子邮件一些样式。虽然没有强制使用HTML,但仍然可以只使用纯文本。
注意,该函数接受将电子邮件发送给多个收件人,也允许附加多个文件。
我只在python2上尝试过,但我认为它在python3上也能正常工作:
import os.path
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
def send_email(subject, message, from_email, to_email=[], attachment=[]):
"""
:param subject: email subject
:param message: Body content of the email (string), can be HTML/CSS or plain text
:param from_email: Email address from where the email is sent
:param to_email: List of email recipients, example: ["a@a.com", "b@b.com"]
:param attachment: List of attachments, exmaple: ["file1.txt", "file2.txt"]
"""
msg = MIMEMultipart()
msg['Subject'] = subject
msg['From'] = from_email
msg['To'] = ", ".join(to_email)
msg.attach(MIMEText(message, 'html'))
for f in attachment:
with open(f, 'rb') as a_file:
basename = os.path.basename(f)
part = MIMEApplication(a_file.read(), Name=basename)
part['Content-Disposition'] = 'attachment; filename="%s"' % basename
msg.attach(part)
email = smtplib.SMTP('your-smtp-host-name.com')
email.sendmail(from_email, to_email, msg.as_string())
我希望这能有所帮助!: -)
我知道这是一个老问题,但我认为一定有一种比其他例子更简单的方法来做到这一点,因此我做了一个库,在不污染代码库的情况下干净地解决这个问题。包含附件非常简单:
from redmail import EmailSender
from pathlib import Path
# Configure an email sender
email = EmailSender(
host="<SMTP HOST>", port=0,
user_name="me@example.com", password="<PASSWORD>"
)
# Send an email
email.send(
sender="me@example.com",
receivers=["you@example.com"],
subject="An example email"
attachments={
"myfile.txt": Path("path/to/a_file.txt"),
"myfile.html": "<h1>Content of a HTML attachment</h1>"
}
)
你也可以直接附加字节,Pandas DataFrame(根据键中的文件扩展名转换为格式),Matplotlib图或枕头图像。这个库很可能是你需要一个电子邮件发送者的所有功能(它比附件要多得多)。
如何安装:
pip install redmail
你喜欢怎么用就怎么用。我还写了大量的文档:https://red-mail.readthedocs.io/en/latest/
下面是Python 3.6及更新版本的更新版本,使用Python标准库中经过大修的电子邮件模块的EmailMessage类。
import mimetypes
import os
import smtplib
from email.message import EmailMessage
username = "user@example.com"
password = "password"
smtp_url = "smtp.example.com"
port = 587
def send_mail(subject: str, send_from: str, send_to: str, message: str, directory: str, filename: str):
# Create the email message
msg = EmailMessage()
msg['Subject'] = subject
msg['From'] = send_from
msg['To'] = send_to
# Set email content
msg.set_content(message)
path = directory + filename
if os.path.exists(path):
ctype, encoding = mimetypes.guess_type(path)
if ctype is None or encoding is not None:
# No guess could be made, or the file is encoded (compressed), so
# use a generic bag-of-bits type.
ctype = 'application/octet-stream'
maintype, subtype = ctype.split('/', 1)
# Add email attachment
with open(path, 'rb') as fp:
msg.add_attachment(fp.read(),
maintype=maintype,
subtype=subtype,
filename=filename)
smtp = smtplib.SMTP(smtp_url, port)
smtp.starttls() # for using port 587
smtp.login(username, password)
smtp.send_message(msg)
smtp.quit()
