python-发送Email

1、发送简单的邮件

import smtplib
from email.mime.text import MIMEText

msg_from='xxxxxxx@sina.cn'
passwd='xxxxxxx'
msg_to='xxxxxxxx@qq.com'
subject="python邮件测试"
content="这是我使用python smtplib及email模块发送的邮件"
msg = MIMEText(content)
msg['Subject'] = subject
msg['From'] = msg_from
msg['To'] = msg_to

try:

    smtpObj=smtplib.SMTP('smtp.sina.cn',25)
    # smtpObj.connect(mail_host,25)
    smtpObj.login(msg_from,passwd)
    smtpObj.sendmail(msg_from,msg_to,msg.as_string())
    print('邮件发送成功')

except smtplib.SMTPException as e:
    print(e)

2、ssl安全登录，打开debug调试

from email.mime.textimport MIMEText
from smtplibimport SMTP_SSL
fromuser='xxxxx@sina.cn'

pwd='xxxxxxxxxxxx'
touser='xxxxxxxxxxxxxxxxxxxx@qq.com'
host_server='smtp.sina.cn'
subject='你好啊小二'
content='测试哟'

#ssl登陆
smtp=SMTP_SSL(host_server)
#set_debuglevel()是用来调试的。参数值为1表示开启调试模式，参数值为0关闭调试模式
smtp.set_debuglevel(1)
smtp.ehlo(host_server)
smp.login(fromuser,pwd)
msg=MIMEText(content,'plain','utf-8')
msg['Subject']=subject
msg['From']=fromuser
msg['To']=touser

smtp.sendmail(fromuser,touser,msg.as_string())
smtp.quit()
print('发送成功')

3、发送附件邮件

import  smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

msg=MIMEMultipart()  #创建一个带附件的实例
#构建附件
att=MIMEText(open('D:\\test01.xlsx','rb').read(),'base64','utf-8')
att['Content-Type']='application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="test01.xlsx"'
msg.attach(att)
msg.attach(MIMEText('这是文本+附件的邮件发送测试....','plain','utf-8'))
msg['Subject']=('python邮件测试...')
msg['From']=('xxxxxxxxxxxxx@sina.cn')
msg['To']=('xxxxxxxxxxxxxxx@qq.com')
from_user='xxxxxxxxxxxxx@sina.cn'
pwd=***************************
to_user='xxxxxxxxxxxxxx@qq.com'
smtp_server='smtp.sina.cn'

try:

    server=smtplib.SMTP(smtp_server,25)
    print('开始登录')
    server.login(from_user,pwd)
    print('登录成功')
    print('邮件开始发送')
    server.sendmail(from_user,to_user,msg.as_string())
    server.quit()
    print('邮件发送成功')

except smtplib.SMTPException as e:
    print(e)

4、群发和多附件的邮件

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.application import MIMEApplication

def send_mail(receiver,filepath):
    sender='xxx@sina.cn'
    pwd='xxxxx'

    msg=MIMEMultipart()
    msg['Subject'] = '你好啊小二'
    msg['From'] = sender
    smtp_server = 'smtp.sina.cn'

    if len(receiver) > 1:
        msg['To'] = ','.join(receiver)
    else:
        msg['To'] = receiver[0]

    part = MIMEText('hahaha')
    msg.attach(part)

    for path in filepath:
        name = path.split('\\')[-1]
        jpgpart = MIMEApplication(open(path,'rb').read())
        jpgpart.add_header('Content-Disposition','attachment',filename=name)
        msg.attach(jpgpart)

    try:
        server = smtplib.SMTP(smtp_server.25)
        server.login(sender,pwd)
        server.sendmail(sender,receiver,msg.as_string())
        server.quit()
        print('邮件发送成功')
    except Exception as e:
        print(str(e))
if __name__ == '__main__':
    receiver = ['xxxx','xxxxx','yyyyy']
    filepath = ['D:\\xxxx\\a.html','E:\\xxx\\b.jpg']
    send_mail(receiver,filepath)
