Python发送电子邮件

SMTP是发送邮件的协议，Python内置对SMTP的支持（smtplib模块和email模块）,可以发送纯文本邮件、HTML邮件以及带附件的邮件

SMTP：Simple Mail Transfer Protocol简单邮件传输协议，是从源地址到目的地址传送邮件的规则，由该协议控制信件的中转方式

python的smtplib提供了一种很方便的途径传递电子邮件，对SMTP进行了简单的封装

发送纯文本邮件

#导入smtplib模块
from smtplib import SMTP
from email.mime.text import MIMEText
from email.header import Header

def send_email(SMTP_host, from_addr, password, to_addrs, subject, content):
    email_client = SMTP(SMTP_host)
    email_client.login(from_addr, password)
    msg = MIMEText(content,'plain','utf-8')
    msg['Subject'] = Header(subject, 'utf-8')#subject
    msg['From'] = '[e-mail]'
    msg['To'] = "[e-mail]"
    #sendmail(邮件发送者地址，字符串列表（收件人），发送内容)
    email_client.sendmail(from_addr, to_addrs, msg.as_string())
send_email("smtp.163.com","[e-mail]","password","[e-mail]","lsllsldld","hellow")

发送HTML格式的邮件

#导入smtplib模块
from smtplib import SMTP
from email.mime.text import MIMEText
from email.header import Header

def send_email(SMTP_host, from_addr, password, to_addrs, subject, content):
    email_client = SMTP(SMTP_host)
    email_client.login(from_addr, password)
    #发送纯文本邮件 设置为plain,发送html邮件修改为 MIMEText(content,'html','utf-8')
    msg = MIMEText(content,'html','utf-8')
    msg['Subject'] = Header(subject, 'utf-8')#subject
    msg['From'] = '[e-mail]'
    msg['To'] = "[e-mail]"
    #sendmail(邮件发送者地址，字符串列表（收件人），发送内容)
    #发送纯文本邮件
    email_client.sendmail(from_addr, to_addrs, msg.as_string())
send_email("smtp.163.com","[e-mail]","password","[e-mail]","lsllsldld","<h1>sdf</h1><ul><li>2</li></ul>")
