对邮箱的操作

学习地址：http://blog.szwyll.com/archives/146
1.登录邮箱
    # 定义一些常量
    # 收件人email， 发件人email，登录邮箱的授权码（mail_password）
    server = smtplib.SMTP()
    server.connect('smtp.qq.com', 25)
    server.login(mail_name, mail_password)
2.发送邮件
    # 定义邮件内容
    # 纯文本邮件，html文件，包含附件的文件
    # 邮件的必须内容：From：发件人email  To: 收件人email（多个收件人用，隔开）  Subject: 邮件主题
    发送邮件
    server.sendmail(mail_name, receiver, msg.as_string())
    server.quit()

一、发送纯文本文件

import smtplib
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header

receiver = ['xxx@qq.com']
mail_name = 'xxxx@qq.com'  # 发送人邮箱地址
mail_password = 'pqymqfvvlmdabcbc'  # 注意：这里不是密码，而应该填写授权码！！


# 编辑邮件内容
# 1.收件人，主题，正文
msg = MIMEText('hello, send by Python...', 'plain', 'utf-8')
msg['From'] = mail_name
msg['To'] = ''.join(receiver)
msg['Subject'] = Header('来自SMTP的问候...', 'utf-8').encode()

# 发送内容
try:
    # 登陆邮箱
    server = smtplib.SMTP()
    server.connect('smtp.qq.com', 25)
    server.login(mail_name, mail_password)

    # 发送邮件
    server.sendmail(mail_name, receiver, msg.as_string())
    server.quit()
    print('Success')
except smtplib.SMTPException as e:
    print('Failure:', str(e))

二、发送HTML邮件

import smtplib
from email.mime.application import MIMEApplication
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header

receiver = ['xxx@qq.com']
mail_name = 'xxxx@qq.com'  # 发送人邮箱地址
mail_password = 'pqymqfvvlmdabcbi'  # 注意：这里不是密码，而应该填写授权码！！


# 编辑邮件内容
# 1.收件人，主题，正文
msg = MIMEText('<html>'
               '<body>'
               '<h1>Hello</h1>'
               '<p>send by '
               '<a href="http://www.baidu.com">baidu</a>'
               '...'
               '</p></body></html>', 'html', 'utf-8')
msg['From'] = mail_name
msg['To'] = ''.join(receiver)
msg['Subject'] = Header('来自SMTP的问候...', 'utf-8').encode()

# 发送内容
try:
    # 登陆邮箱
    server = smtplib.SMTP()
    server.connect('smtp.qq.com', 25)
    server.login(mail_name, mail_password)

    # 发送邮件
    server.sendmail(mail_name, receiver, msg.as_string())
    server.quit()
    print('Success')
except smtplib.SMTPException as e:
    print('Failure:', str(e))

三、发送附件邮件

import smtplib
from email import encoders
from email.mime.application import MIMEApplication
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header

receiver = ['xxx@qq.com']
mail_name = 'xxxx@qq.com'  # 发送人邮箱地址
mail_password = 'pqymqfvvlmdabcbc'  # 注意：这里不是密码，而应该填写授权码！！


# 编辑邮件内容
# 1.收件人，主题，正文
# 邮件本身(MIMEMultipart) = 邮件正文(MIMEText) + MIMEBase(附件)
#
msg = MIMEMultipart()
# 定义发件人，收件人，邮件主题
msg['From'] = mail_name
msg['To'] = ''.join(receiver)
msg['Subject'] = Header('来自SMTP的问候...', 'utf-8').encode()
# 添加邮件正文
msg.attach(MIMEText('send with file...', 'plain', 'utf-8'))
# 添加附件
with open('F:\python_requests\myU.jpg', 'rb') as f:
    # 设置附件的MIME和文件名
    mime = MIMEBase('image', 'jpg', filename='myU.jpg')
    # 加上必要的头信息：
    mime.add_header('Content-Disposition', 'attachment', filename='test.png')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-Id', '0')
    # 读取附件内容
    mime.set_payload(f.read())
    # 用Base64编码
    encoders.encode_base64(mime)
    # 添加到MIMEMultipart
    msg.attach(mime)

try:
    # 登陆邮箱
    server = smtplib.SMTP()
    server.connect('smtp.qq.com', 25)
    server.login(mail_name, mail_password)

    # 发送邮件
    server.sendmail(mail_name, receiver, msg.as_string())
    server.quit()
    print('Success')
except smtplib.SMTPException as e:
    print('Failure:', str(e))

四、再三的基础上将附件嵌入到正文

import smtplib
from email import encoders
from email.mime.application import MIMEApplication
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header

receiver = ['xxx@qq.com']
mail_name = 'xxxx@qq.com'  # 发送人邮箱地址
mail_password = 'pqymqfvvlmdabcbc'  # 注意：这里不是密码，而应该填写授权码！！


# 编辑邮件内容
# 1.收件人，主题，正文
# 邮件本身(MIMEMultipart) = 邮件正文(MIMEText) + MIMEBase(附件)
# alternative：利用MIMEMultipart就可以组合一个HTML和Plain，要注意指定subtype是alternative：
# 如果收件人无法查看HTML格式的邮件，就可以自动降级查看纯文本邮件。

msg = MIMEMultipart('alternative')
# 定义发件人，收件人，邮件主题

smtp_server = 'smtp.qq.com'
smtp_port = 587
msg['From'] = mail_name
msg['To'] = ''.join(receiver)
msg['Subject'] = Header('来自SMTP的问候...', 'utf-8').encode()
# 添加邮件正文
msg.attach(MIMEText('hello', 'plain', 'utf-8'))
msg.attach(MIMEText('<html><body><h1>Hello</h1>' +
    '<p><img src="cid:0"></p>' +
    '</body></html>', 'html', 'utf-8'))
# 添加附件
with open('F:\python_requests\myU.jpg', 'rb') as f:
    # 设置附件的MIME和文件名
    mime = MIMEBase('image', 'jpg', filename='myU.jpg')
    # 加上必要的头信息：
    mime.add_header('Content-Disposition', 'attachment', filename='test.png')
    mime.add_header('Content-ID', '<0>')
    mime.add_header('X-Attachment-Id', '0')
    # 读取附件内容
    mime.set_payload(f.read())
    # 用Base64编码
    encoders.encode_base64(mime)
    # 添加到MIMEMultipart
    msg.attach(mime)

try:
    # 登陆邮箱
    server = smtplib.SMTP(smtp_server, smtp_port)
    server.starttls()
    # server = smtplib.SMTP()
    # server.connect('smtp.qq.com', 25)
    server.login(mail_name, mail_password)

    # 发送邮件
    server.sendmail(mail_name, receiver, msg.as_string())
    server.quit()
    print('Success')
except smtplib.SMTPException as e:
    print('Failure:', str(e))
