使用python發(fā)送郵件的流程：

1、獲得smtp服務(wù)

2、連接服務(wù)器

3、模擬客戶端登錄

4、實(shí)現(xiàn)郵件發(fā)送

5、退出登錄

發(fā)送不帶附件郵件

from email.mime.text import MIMEText

import smtplib

msg = MIMEText(‘hello,this is a mail...’,’plain’,’utf-8’)

參數(shù)：郵件正文、‘plain’表示純文本、utf-8編碼

msg[‘From’] = _formate_addr(‘發(fā)送者’)

msg[‘To’] = _format_addr(‘接收者’)

msg[‘Subject’] = ‘郵件主題’

server = smtplib.SMTP()

server.set_debuglevel(1)

server.connect(smtp_server,25)

server.login(發(fā)送者帳號(hào)，發(fā)送者密碼)

server.sendmail(發(fā)送者帳號(hào)，接收地址，str(msg))

server.quit()

發(fā)送帶附件郵件

import smtplib

from email.mime.text import MIMEText

from email.mime.multipart import

MIMEMultipart

from email.mime.application import

MIMEApplication

msg = MIMEMultipart()

msg[‘From’] = _formate_addr(‘發(fā)送者’)

msg[‘To’] = _format_addr(‘接收者’)

msg[‘Subject’] = ‘郵件主題’

#純文本部分

msg.attach(MIMEText(‘hello,this is a mail...’,’plain’,’utf-8’)

#首先是xlsx類型的附件

xlsxpart =MIMEApplication(open('test.xlsx', 'rb').read())

xlsxpart.add_header('Content-Disposition','attachment', filename='test.xlsx')

msg.attach(xlsxpart)

# jpg類型的附件

jpgpart = MIMEApplication(open('beauty.jpg','rb').read())

jpgpart.add_header('Content-Disposition','attachment', filename='beauty.jpg')

msg.attach(jpgpart)

# mp3類型的附件

mp3part = MIMEApplication(open('kenny.mp3','rb').read())

mp3part.add_header('Content-Disposition','attachment', filename='benny.mp3')

msg.attach(mp3part)

server = smtplib.SMTP()

server.set_debuglevel(1)

server.connect(smtp_server,25)

server.login(發(fā)送者帳號(hào)，發(fā)送者密碼)

server.sendmail(發(fā)送者帳號(hào)，接收地址，str(msg))

server.quit()
