python自动化---各类发送邮件方法及其可能的错误

一、发送文本邮件

可能的问题1.：需要注意，目前QQ邮箱来讲，不能收到完整的邮件，即有些内容不能显示，最好全部使用网易邮箱：

可能的问题2.：在以往的文本邮件发送中，只写了

msg = MIMEText('hello,world,中文邮件测试', 'text', 'utf-8')
msg['Subject'] = Header(subject, 'utf-8')

目前来讲，需要有三个参数，即

#  中文需要参数utf-8
msg = MIMEText('hello,world,中文邮件测试', 'text', 'utf-8')
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = '[email protected]'

文本代码参考（写代码的时候是本人的邮箱，在此已将邮箱更改，复制的时候需要注意）

# -*- coding:utf-8 -*-
import smtplib
from email.mime.text import MIMEText
from email.header import Header

#  发送邮箱
sender = '[email protected]'

#  接收邮箱
receiver = '[email protected]'

#  发送邮件主题
subject = 'Python email testing'

#  发送邮箱服务器
smtpserver = 'smtp.163.com'

#  发送邮箱用户名/密码
username = "[email protected]"
password = "123456"

#  中文需要参数utf-8
msg = MIMEText('hello,world,中文邮件测试', 'text', 'utf-8')
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = '[email protected]'

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

test_text_mail

二、发送HTML邮件

将参数内容修改即可：如下

#  HTML形式的文件内容
msg = MIMEText('
你好！！欢迎使用html格式','html','utf-8')
msg['Subject'] = Header(subject, 'utf-8')
# msg['From'] = 'lemon'
# msg['To'] = '[email protected]'

其他内容，与上述代码一致；

三、发送img邮件

# -*- coding:utf-8 -*-
import smtplib
import mimetypes
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.header import Header


sender = '[email protected]'
receiver = '[email protected]'
subject = 'Python email image testing'
smtpserver = 'smtp.163.com'
username = "[email protected]"
password = "123456"

#  发送图片附件的邮件
msg = MIMEMultipart()
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = '[email protected]'

txt = MIMEText("这是中文的邮件内容哦","plain",'utf-8')
msg.attach(txt)

file1 = r"E:\images\2.jpg"
image = MIMEImage(open(file1, 'rb').read())
image.add_header('Content-ID', '')
msg.attach(image)

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

test_img_mail

显示如下：

新内容：

msg = MIMEMultipart()
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = '[email protected]'

txt = MIMEText("这是中文的邮件内容哦","plain",'utf-8')
msg.attach(txt)

file1 = r"E:\images\2.jpg"
image = MIMEImage(open(file1, 'rb').read())
image.add_header('Content-ID', '')
msg.attach(image)

以上是将img图片以附件格式发送，若让其插在正文中，代码改成

# -*- coding:utf-8 -*-
import smtplib
import mimetypes
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.header import Header

sender = '[email protected]'
receiver = '[email protected]'
subject = 'Python email image testing2'
smtpserver = 'smtp.163.com'
username = "[email protected]"
password = "123456"

#  发送图片插在正文中的邮件
msg = MIMEMultipart()
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = 'def@163.com'

msgText = MIMEText('Some HTML text and an image.

Nifty!','html')
msg.attach(msgText)

file1 = r"E:\images\2.jpg"
image = MIMEImage(open(file1, 'rb').read())
image.add_header('Content-ID', '')
msg.attach(image)

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

四、发送附件邮件

import mimetypes
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.header import Header

sender = '[email protected]'
receiver = '[email protected]'
subject = 'Python email attachment testing2'
smtpserver = 'smtp.163.com'
username = "[email protected]"
password = "123456"

#  发送有附件的邮件
msg = MIMEMultipart('related')
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = '[email protected]'

#  构造附件
msgatt = MIMEText(open(r"E:\attachment\ API.docx").read(),'base64','utf-8')
msgatt["Content-Type"] = 'application/octet-stream'
msgatt["Content-Disposition"] = 'attachment;filename="API.docx"'
msg.attach(msgatt)

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

五、发送群发邮件

添加多个接收人即可：

receiver = ['[email protected]','[email protected]','[email protected]']

六、发送各种元素都包含的邮件

# -*- coding:utf-8 -*-
import smtplib
import mimetypes
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.header import Header

sender = '[email protected]'
receiver = '[email protected]'
subject = 'Python email many testing2'
smtpserver = 'smtp.163.com'
username = "[email protected]"
password = "123456"

#  构造消息容器
msg = MIMEMultipart()
msg['Subject'] = Header(subject, 'utf-8')
msg['From'] = 'lemon'
msg['To'] = '[email protected]'

#  构造文件的本身，用html格式：html = """

    
        
你好！！欢迎使用html格式
    
"""

#  记录以上信息
part2 = MIMEText(html, 'html','utf-8')
msg.attach(part2)

#  构造附件
msgatt = MIMEText(open(r"E:\attachment\API.docx").read(),'base64','utf-8')
msgatt["Content-Type"] = 'application/octet-stream'
msgatt["Content-Disposition"] = 'attachment;filename="API.docx"'
msg.attach(msgatt)

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

注意：此处，若将html格式写成

html = """\
Hi!
       How are you?
       Here is the you wanted.
""" 

则邮件无法发送到，故一定要写成规范的格式；

七、基于SSL的邮件
