两种python实现自动发邮件的方法

法一

from email.mime.text import MIMEText
from email.header import Header
from email.mime.multipart import MIMEMultipart
import smtplib
from template import DATETIME

class Email(object):

    def __init__(self, file_path, file_name):
        self.subject = "********"  # 邮件标题
        self.sender = '****@huawei.com'  # 发件人
        self.receivers = ["*****@huawei.com", "*****@huawei.com", "***@huawei.com", "*****@huawei.com"]  # 收件人
        self.cc = ['***@huawei.com']  # 抄送人
        self.file_path = file_path
        self.file_name = file_name  # 发送附件名字

    def message_init(self, html):
        # 创建一个带附件的实例
        message = MIMEMultipart()  # 发送消息定义
        message['Subject'] = Header(self.subject, 'utf-8')
        message['From'] = self.sender  # 发件人
        message['To'] = ', '.join(self.receivers)  # 收件人
        message['Cc'] = ', '.join(self.cc)  # 抄送者
        # 解决乱码,html是html格式的str
        message_context = MIMEText(html, _subtype='html', _charset='utf-8')
        # 邮件正文内容
        message.attach(message_context)
        att1 = MIMEText(open('{}/{}'.format(self.file_path, self.file_name), 'rb').read(), 'base64', 'utf-8')
        att1["Content-Type"] = 'application/octet-stream'
        # 附件名称
        att1["Content-Disposition"] = 'attachment; filename={}'.format(self.file_name.split('\\')[-1])
        message.attach(att1)  # 添加附件
        return message

    def send_email(self, html):
        message = self.message_init(html)
        smtp_obj = smtplib.SMTP('smtp.huawei.com')
        smtp_obj.login('工号', "密码")  # 打开电脑的账号密码
        smtp_obj.sendmail(self.sender, self.receivers + self.cc, message.as_string())
        smtp_obj.quit()

法二

#coding: utf-8
import smtplib
from email.mime.text import MIMEText
from email.header import Header

sender = '邮箱地址'
receiver = '邮箱地址'
username = '工号'
password = '密码'

subject = 'python email test'
#中文需参数‘utf-8’，单字节字符不需要
msg = MIMEText('你好呀，最近好么','plain','utf-8')
msg['Subject'] = Header(subject, 'utf-8')
msg["From"] = sender
msg["To"] = str(receiver)
msg["Reply-To"] = sender

smtpserver = 'smtpscn.huawei.com'
server_port = 587
#print email_message
#创建SMTP对象
smtp = smtplib.SMTP(smtpserver,server_port)
#smtp.set_debuglevel(1)
#向mail发送SMTP "ehlo" 命令
smtp.ehlo()
#启动TLS模式，mail要求
smtp.starttls()
#用户验证
smtp.login(username, password)
#发送邮件
smtp.sendmail(sender, receiver, msg.as_string())
#退出
smtp.quit()
