我正在构建一封嵌入图像 base64 的电子邮件,这样当我的同事打开它时它可以正确显示。我不太确定如何从文件中到达那里以及我现在拥有的内容。
这运行得很好,但我无法成功嵌入图像。我需要嵌入 image1.jpg。
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
# me == my email address
# you == recipient's email address
me = "me@.com"
you = "you@.com"
# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Sent using Python :) "
msg['From'] = me
msg['To'] = you
# Create the body of the message (a plain-text and an HTML version).
text = "This is an HTML body. I would like to embed a base64 image."
html = """\
<html>
<body>
<p>This is an HTML body.<br>
I would like to embed a base64 image.
</p>
</body>
</html>
"""
# 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)
# Send the message via local SMTP server.
s = smtplib.SMTP('localhost')
# sendmail function takes 3 arguments: sender's address, recipient's address
# and message to send - here it is sent as one string.
s.sendmail(me, you, msg.as_string())
s.quit()
最佳答案
我仅使用嵌入 HTML 文件中的 Base64 图像进行了测试,但它应该是相同的。
<小时/>您必须将图像读取为字节,编码为base64,将其转换为字符串,然后在
中使用 '<img src="data:image/jpeg;base64,' + data_base64 + '">'
在 HTML 文件中嵌入 Base64 图像的工作示例:
import base64
data = open('image.jpg', 'rb').read() # read bytes from file
data_base64 = base64.b64encode(data) # encode to base64 (bytes)
data_base64 = data_base64.decode() # convert bytes to string
print(data_base64)
#html = '<html><body><img src="data:image/jpeg;base64,' + data_base64 + '"></body></html>' # embed in html
html = '<img src="data:image/jpeg;base64,' + data_base64 + '">' # embed in html
open('output.html', 'w').write(html)
