python 發送郵件的兩種方式【終極篇】

一，利用python自帶的庫?smtplib簡單高效

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header
import smtplib
from django.conf import settingsmail_host = settings.EMAIL_HOSTmail_user = settings.EMAIL_HOST_USERmail_pass = settings.EMAIL_HOST_PASSWORDsubject = subjectsender = settings.EMAIL_FROMreceiver = settings.TEST_EMAIL_TOmsg = MIMEMultipart()part = MIMEText(str(data), 'html')msg.attach(part)msg['from'] = Header('標題，也可以寫郵箱賬號', 'utf-8')msg['Subject'] = Header(subject, 'utf-8')msg["Accept-Language"] = "zh-CN"msg["Accept-Charset"] = "ISO-8859-1,utf-8"try:server = smtplib.SMTP()server.connect(mail_host)server.login(mail_user, mail_pass)server.sendmail(sender, receiver, msg.as_string())server.quit()except Exception:logger.error(msg=traceback.format_exc())

二，django郵件功能的使用

#settings.py:
# qq IMAP/SMTP 配置
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.qq.com'
EMAIL_PORT = 25  # 或者 465/587是設置了 SSL 加密方式
# 發送郵件的郵箱
EMAIL_HOST_USER = ‘你的郵箱’
# 在郵箱中設置的客戶端授權密碼
EMAIL_HOST_PASSWORD = ‘你的IMAP授權碼’  # 如果重新設置了新的授權碼,直接使用最新的授權碼即可
EMAIL_USE_TLS = True  # 這里必須是 True，否則發送不成功
# 收件人看到的發件人, 必須是一直且有效的
EMAIL_FROM = ‘Tencent<你的郵箱>'
"""
# qq POP3/SMTP 配置
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.qq.com'
EMAIL_PORT = 110  # 或者 995是設置了 SSL 加密方式
#發送郵件的郵箱
EMAIL_HOST_USER = '你的qq郵箱'
#在郵箱中設置的客戶端授權密碼
EMAIL_HOST_PASSWORD = '你的pop3授權碼'  # 如果重新設置了新的授權碼,直接使用最新的授權碼即可
EMAIL_USE_TLS = True  # 這里必須是 True，否則發送不成功
#收件人看到的發件人
EMAIL_FROM = ‘Tencent<xxx@qq.com>’
"""from django.core.mail import send_mail
from django.core.mail import EmailMultiAlternatives
#send mail
def send_email(file_path, total, typical, dts):html_content = loader.render_to_string('email.html',{'dts': dts,'total': total,'typical': typical})email = EmailMultiAlternatives('title', html_content, settings.EMAIL_FROM, settings.EMAIL_TO)email.attach_file(file_path)email.content_subtype = "html"email.send()

?三、發送帶圖片和附件的郵件

import os
import datetime
import smtplib
import logging
import traceback
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage
from email.mime.text import MIMEText
from email.header import Header

def send_img_mail(data, subject, recivers, attach_file=None):
    base_dir = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
    mail_host = settings.EMAIL_HOST
    mail_user = settings.EMAIL_HOST_USER
    mail_pass = settings.EMAIL_HOST_PASSWORD
    subject = subject
    sender = settings.EMAIL_FROM
    receiver = recivers

    msg = MIMEMultipart()
    msg.attach(MIMEText(str(data), 'html'))

    with open(os.path.join(base_dir, 'dist/static/img/zk_header.png'), 'rb') as f:
        msgImage = MIMEImage(f.read())
    msgImage.add_header('Content-ID', '<image1>')
    msg.attach(msgImage)

    with open(os.path.join(base_dir, 'dist/static/img/zk_footer.jpg'), 'rb') as f:
        msgImage = MIMEImage(f.read())
    msgImage.add_header('Content-ID', '<image2>')
    msg.attach(msgImage)

    if attach_file:
        last_month = datetime.datetime.today() - relativedelta(months=1)
        attachment = MIMEText(open(attach_file, 'rb').read(), 'base64', 'gb2312')
        attachment["Content-Type"] = 'application/octet-stream'
        attachment["Content-Disposition"] = 'attachment; filename="XXX產品{0}月新增XX問題.xls"'. \
            format(last_month.month)
        msg.attach(attachment)

    msg['from'] = Header('XXXXXX', 'utf-8')
    msg['Subject'] = Header(subject, 'utf-8')
    msg["Accept-Language"] = "zh-CN"
    msg["Accept-Charset"] = "ISO-8859-1,utf-8"

    try:
        server = smtplib.SMTP()
        server.connect(mail_host)
        server.login(mail_user, mail_pass)
        server.sendmail(sender, receiver, msg.as_string())
        server.quit()
    except Exception:
        logger.error(msg=traceback.format_exc())

html文件格式：

<img src="cid:image1">
<img src="cid:image2">
