一、smtplib模块:
主要通过SMTP类与邮件系统进行交互。使用方法如下:
1.实例化一个SMTP对象:
s = smtplib.SMTP(邮件服务地址,端口号)
s = smtplib.SMTP_SSL(邮件服务地址,端口号)
2.登陆邮件,权限验证:
s.login(用户名,密码)
3.发送邮件:
s.sendmail(发件人邮箱,收件人邮箱,发送内容)
4.断开连接:
s.close()
二、email模块:
email模块:支持发送的邮件内容为纯文本、HTML内容、图片、附件。email模块中有几大类来针对不同的邮件内容形式,常用如下:
MIMEText:(MIME媒体类型)内容形式为纯文本、HTML页面。
MIMEImage:内容形式为图片。
MIMEMultupart:多形式组合,可包含文本和附件。
每一类对应的导入方式:
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
三、MIMEText:
MIMEText(msg,type,chartset)
msg:文本内容
type:文本类型默认为plain(纯文本)
发送HTML格式的时候,修改为html,但同时要求msg的内容也是html的格式。
chartset:文本编码,中文为“utf-8”
# 构造TEXT格式的消息
msg = MIMEText("hello.text","plain","utf-8")
msg["Subject"] = "xxxxx"
msg["From"] = "xxxx"
msg["To"] = "xxxx"
#发送以上构造的邮件内容要使用as_string将构造的邮件内容转换为string形式。
s.sendmail("xxx","xxx",msg.as_string)
四、MIMEImage、MIMEMultipart:
msg = MIMEMultipart()
#实例化一个文本对象
msg_sub = MIMEText("hello.text","plain","utf-8")
#将text消息添加到MIMEMultipart中,作为邮件正文。
msg.attach(msg_sub)
#图片作为附件
import os
img_datas = open(os.getcwd()+ "/reports/xxxx.png","rb").read()
msg_img = MIMEImage(img_data)
msg_img.add_header('Content-Disposition','attachment', filename = "xxxx.png" )
msg_img.add_header('Content-ID','<0>')
#将图片添加到MIMEMultiplart中,作为附件发送。
msg.attach(mag_img)
源代码如下:
发送文本邮件:
1 import smtplib

7
8 subject = 'python发邮件测试' #主题
9 content = '这是我使用python smtplib模块和email模块自动发送的邮件' #正文
10
11 msg = MIMEText(content,'plain','utf-8')
12 msg['Subject'] = subject
13 msg['From'] = sender
14 msg['TO'] = receivers
15
16 try:
17 s = smtplib.SMTP_SSL('smtp.qq.com',465)
