发送包含嵌入图像的多段html电子邮件

我一直在玩python中的电子邮件模块，但我想能够知道如何嵌入html中包含的图像。发送包含嵌入图像的多段html电子邮件

因此，例如，如果身体是一样的东西

<img src="../path/image.png"></img>

我想嵌入image.png到电子邮件，和src属性应与content-id更换。有人知道怎么做这个吗？

这是我找到的一个例子。

Recipe 473810: Send an HTML email with embedded image and plain text alternate：

HTML是首选那些希望发送电子邮件与丰富的文字，布局和图形的方法。通常是需要将图形嵌入消息中，因此收件人可以直接显示消息，而无需进一步下载。

一些邮件代理不支持HTML或他们的用户更喜欢收到纯文本消息。 HTML 消息的发件人应该包含明文消息作为这些用户的备用消息。

这个配方发送一个简短的HTML消息与一个嵌入式图像和一个替代纯文本消息。

# Send an HTML email with an embedded image and a plain text message for 
# email clients that don't want to display the HTML. 

from email.MIMEMultipart import MIMEMultipart 
from email.MIMEText import MIMEText 
from email.MIMEImage import MIMEImage 

# Define these once; use them twice! 
strFrom = '[email protected]' 
strTo = '[email protected]' 

# Create the root message and fill in the from, to, and subject headers 
msgRoot = MIMEMultipart('related') 
msgRoot['Subject'] = 'test message' 
msgRoot['From'] = strFrom 
msgRoot['To'] = strTo 
msgRoot.preamble = 'This is a multi-part message in MIME format.' 

# Encapsulate the plain and HTML versions of the message body in an 
# 'alternative' part, so message agents can decide which they want to display. 
msgAlternative = MIMEMultipart('alternative') 
msgRoot.attach(msgAlternative) 

msgText = MIMEText('This is the alternative plain text message.') 
msgAlternative.attach(msgText) 

# We reference the image in the IMG SRC attribute by the ID we give it below 
msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<br><img src="cid:image1"><br>Nifty!', 'html') 
msgAlternative.attach(msgText) 

# This example assumes the image is in the current directory 
fp = open('test.jpg', 'rb') 
msgImage = MIMEImage(fp.read()) 
fp.close() 

# Define the image's ID as referenced above 
msgImage.add_header('Content-ID', '<image1>') 
msgRoot.attach(msgImage) 

# Send the email (this example assumes SMTP authentication is required) 
import smtplib 
smtp = smtplib.SMTP() 
smtp.connect('smtp.example.com') 
smtp.login('exampleuser', 'examplepass') 
smtp.sendmail(strFrom, strTo, msgRoot.as_string()) 
smtp.quit()

对于Python版本3.4及以上

接受的答案是优秀的，但老。我认为它需要更新。

这里是你如何在新的Python版本（3.4及以上）做到这一点：

from email.message import EmailMessage 
from email.utils import make_msgid 
import mimetypes 

msg = EmailMessage() 

# generic email headers 
msg['Subject'] = 'Hello there' 
msg['From'] = 'ABCD <[email protected]>' 
msg['To'] = 'PQRS <[email protected]>' 

# set the plain text body 
msg.set_content('This is a plain text body.') 

# now create a Content-ID for the image 
image_cid = make_msgid(domain='xyz.com') 
# if `domain` argument isn't provided, it will 
# use your computer's name 

# set an alternative html body 
msg.add_alternative("""\ 
<html> 
    <body> 
     <p>This is an HTML body.<br> 
      It also has an image. 
     </p> 
     <img src="cid:{image_cid}"> 
    </body> 
</html> 
""".format(image_cid=image_cid[1:-1]), subtype='html') 
# image_cid looks like <[email protected]> 
# to use it as the img src, we don't need `<` or `>` 
# so we use [1:-1] to strip them off 


# now open the image and attach it to the email 
with open('path/to/image.jpg', 'rb') as img: 

    # know the Content-Type of the image 
    maintype, subtype = mimetypes.guess_type(img.name)[0].split('/') 

    # attach it 
    msg.get_payload()[1].add_related(img.read(), 
             maintype=maintype, 
             subtype=subtype, 
             cid=image_cid) 


# the message is ready now 
# you can write it to a file 
# or send it using smtplib
