Examples of python's seven mail content delivery methods

I. mail in the form of documents

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText
from email.header import Header

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msg = MIMEText(' hello ','text','utf-8')# Chinese required parameters' utf-8' , single-byte characters are not required 
msg['Subject'] = Header(subject, 'utf-8')

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

Two, HTML form of mail

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'

msg = MIMEText('</pre>
<h1> hello </h1>
<pre>','html','utf-8') 

msg['Subject'] = subject 

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

Three, with pictures of the HTML mail

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage 

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***' 

msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message' 

msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.
<img alt="" src="cid:image1" />
good!','html','utf-8')
msgRoot.attach(msgText) 

fp = open('h:\python\1.jpg', 'rb')
msgImage = MIMEImage(fp.read())
fp.close() 

msgImage.add_header('Content-ID', '')
msgRoot.attach(msgImage) 

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

Mail with attachments

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage 

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***' 

msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message' 

# Construction accessories 
att = MIMEText(open('h:\python\1.jpg', 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="1.jpg"'
msgRoot.attach(att) 

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

Group mail

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText 

sender = '***'
receiver = ['***','****', ... ]
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***' 

msg = MIMEText(' hello ','text','utf-8') 

msg['Subject'] = subject 

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

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage 

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***' 

# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link" 

# Create the body of the message (a plain-text and an HTML version).
text = "Hi!nHow are you?nHere is the link you wanted:nhttp://www.python.org"
html = """

 
Hi!

       How are you?

       Here is the <a href="http://www.python.org">link</a> you wanted.

 

""" 

# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html') 

# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)
# Construction accessories 
att = MIMEText(open('h:\python\1.jpg', 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="1.jpg"'
msg.attach(att) 

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

Seven, ssl-based mail

#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText
from email.header import Header
sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***' 

msg = MIMEText(' hello ','text','utf-8')# Chinese required parameters' utf-8' , single-byte characters are not required 
msg['Subject'] = Header(subject, 'utf-8') 

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.ehlo()
smtp.starttls()
smtp.ehlo()
smtp.set_debuglevel(1)
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()
