发送邮件

1.使用smtplib

 

#encoding=utf-8
import smtplib

hostname = "smtp.ym.163.com"
port = 25
user = "[email protected]"
password = "your password"

def sendEmail(content,toaddrs):
    msg = "From: %s\r\nTo: %s\r\n\r\n" % (user, ", ".join(toaddrs))
    msg += content
    server = smtplib.SMTP(hostname,port)
    server.login(user,password)
    server.sendmail(user,toaddrs,msg)
    server.quit()

if __name__ == '__main__':
    content = "Hello,I'm Tim.Thank your supports!"
    toaddrs = ["[email protected]","[email protected]",]
    sendEmail(content,toaddrs)

 

 

smtplib.SMTP([host[, port[, local_hostname[, timeout]]]])

SMTP类构造函数，表示与SMTP服务器之间的连接，通过这个连接我们可以向smtp服务器发送指令，执行相关操作（如：登陆、发送邮件）。

 

SMTP.connect([host[, port]])

连接到指定的smtp服务器。参数分别表示smpt主机和端口。

 

SMTP.login(user, password)

登陆到smtp服务器。

 

SMTP.sendmail(from_addr, to_addrs, msg[, mail_options, rcpt_options])

发送邮件。

 

SMTP.quit()

断开服务器连接。

 

邮件内容必须遵循smtp协议，包括发件人、收件人、标题、内容、附件等。例子中的msg就是这么构造的，如果邮件比较复杂，就需要用到email模块。

 

2.使用email及子模块

 

 

# -*- coding: utf-8 -*-

import os
import smtplib
import mimetypes
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.MIMEAudio import MIMEAudio
from email.MIMEImage import MIMEImage
from email.Encoders import encode_base64

def sendMail(subject, text, *attachmentFilePaths):
    gmailUser = '[email protected]'
    gmailPassword = '******'
    recipient = '[email protected]'

    msg = MIMEMultipart()
    msg['From'] = gmailUser
    msg['To'] = recipient
    msg['Subject'] = subject
    msg.attach(MIMEText(text))

    for attachmentFilePath in attachmentFilePaths:
        msg.attach(getAttachment(attachmentFilePath))

    mailServer = smtplib.SMTP('smtp.gmail.com', 587)
    mailServer.ehlo()
    mailServer.starttls()
    mailServer.ehlo()
    mailServer.login(gmailUser, gmailPassword)
    mailServer.sendmail(gmailUser, recipient, msg.as_string())
    mailServer.close()

    print('Sent email to %s' % recipient)

def getAttachment(attachmentFilePath):
    contentType, encoding = mimetypes.guess_type(attachmentFilePath)

    if contentType is None or encoding is not None:
        contentType = 'application/octet-stream'

    mainType, subType = contentType.split('/', 1)
    file = open(attachmentFilePath, 'rb')

    if mainType == 'text':
        attachment = MIMEText(file.read())
    elif mainType == 'message':
        attachment = email.message_from_file(file)
    elif mainType == 'image':
        attachment = MIMEImage(file.read(),_subType=subType)
    elif mainType == 'audio':
        attachment = MIMEAudio(file.read(),_subType=subType)
    else:
        attachment = MIMEBase(mainType, subType)
    attachment.set_payload(file.read())
    encode_base64(attachment)

    file.close()

    attachment.add_header('Content-Disposition', 'attachment',   filename=os.path.basename(attachmentFilePath))
    return attachment


# start to test
sendMail('here is a subject', 'Send a email with Gmail','C:\AppServ\www\python\wx.zip')
