我正在尝试将图像嵌入电子邮件中。我遵循了示例here，here和here以及其他示例，但是我无法显示图像。
import smtplib
import os
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage
logo = 'mylogo.png'
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
html = """\
<html>
<head></head>
<body>
<p>GREETING<br><br>
SOME TEXT<br>
MORE TEXT<br><br>
FAREWELL <br><br>
DISCLAIMER
</p>
<img src="cid:image1" alt="Logo" \>
</body>
</html> """
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html', 'utf-8')
msg.attach(part1)
msg.attach(part2)
fp = open(logo, 'rb')
msgImage = MIMEImage(fp.read())
fp.close()
msgImage.add_header('Content-ID', '<image1>')
msgImage.add_header('Content-Disposition', 'inline', filename=os.path.basename(logo))
msgImage.add_header("Content-Transfer-Encoding", "base64")
msg.attach(msgImage)
s = smtplib.SMTP(smtp_server,25)
s.sendmail(sender, recipient, msg.as_string())
s.quit()
[执行此操作时，我得到一个空的身体，上面有一个红色的十字，没有图像。如何使图像与电子邮件正文内嵌显示？
[我正在使用Outlook2016。我知道我可以在使用Outlook本身时插入图片，并且我收到'普通'电子邮件，其他人在文本中插入了图像，因此，这肯定意味着我必须能够查看从python脚本生成的图像？
编辑：我已经看过给定的here解决方案，建议作为可能的重复方案，但这也没有解决我的问题。
我也尝试过将相同的电子邮件发送到Gmail和Hotmail帐户，并且仍然出现相同的问题，因此该问题显然与代码有关。
我在Outlook 2013中找到了解决方案：
Outlook似乎在查找跨度标签以及一些图像信息，例如高度和宽度（目前为硬编码）和id等（请参见下文）。我将图像包装在此html文本中，然后还添加了图像作为附件使用与我的cid和id相同的编号。图像然后在Outlook中显示为嵌入式文件。
# loop through all uploaded files and add as attachments
for index, file in enumerate(attachment):
with open(file, "rb") as fp:
data = fp.read()
fileType = os.path.splitext(file)[-1].strip(".")
ctype, _ = mimetypes.guess_type(file)
if embedImages and "image/" in ctype:
image = Image.open(data)
# Build out the html for the email
message += '<span style = "mso-no-proof:yes"><img width = 1280 height = 1920 id = "%s" src = "cid:%s"></span>' % (index, index)
# Define the image's ID
msgImage = MIMEImage(data, _subtype=fileType)
msgImage.add_header('Content-ID', '<%s>' % index)
msg.attach(msgImage)
att = MIMEApplication(data, _subtype=fileType)
att.add_header("Content-Disposition", "attachment", filename="%s" % index)
msg.attach(att)
else:
att = MIMEApplication(data, _subtype=fileType)
att.add_header("Content-Disposition", "attachment", filename=fileName)
msg.attach(att)
fp.close()
# Attach html text
if message:
if embedImages or "mimeType" in kwargs:
msg.attach(MIMEText(message, kwargs["mimeType"], 'utf-8'))
else:
msg.attach(MIMEText(message, "plain", 'utf-8'))
这里是使用MIMEMultipart（'related'）的另一种解决方案，因此您不必处理Outlook中的跨度。适用于任何类型的多个附件。 （除非另有说明，否则图像将被嵌入）
# Determine attach type - defaults to attached only
embedImages = kwargs["embedImages"] if "embedImages" in kwargs else False
# Create the root message and fill in the from, and subject headers
msgRoot = MIMEMultipart('related')
msgRoot["Subject"] = subject
msgRoot["From"] = kwargs["fromAddr"] if "fromAddr" in kwargs else noreply
# 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)
# Get Recipient Type
recipientType = kwargs.get("recipientType")
# Chunk Process Recipients
batchSize = 100
for i in range(0, len(recipientList), batchSize):
# Handle 100 recipients at a time
recipients = recipientList[i:i + batchSize]
# Set the to, bcc or cc in root message
if recipientType == "bcc":
msgRoot["Bcc"] = ", ".join(recipients)
elif recipientType == "cc":
msgRoot["Cc"] = ", ".join(recipients)
else:
msgRoot["To"] = ", ".join(recipients)
# Add Attachments
if attachment and isinstance(attachment, str):
# For backwards compatibility turn single attachment into a list
attachment = [attachment]
# loop through all uploaded files and add as attachments
for index, file in enumerate(attachment):
with open(file, "rb") as fp:
# guess the file type from mimetypes
ctype, _ = mimetypes.guess_type(file)
if embedImages and "image/" in ctype:
# Build out the html for the email
message += '<p><img src="cid:%s"></p>' % index
msgImage = MIMEImage(fp.read())
# Define the image's ID in header
msgImage.add_header('Content-ID', '<%s>' % index)
# attach it to root
msgRoot.attach(msgImage)
else:
fileName = alias if alias and len(attachment) == 1 else os.path.basename(file)
msgApp = MIMEApplication(fp.read())
# define header as attachment
msgApp.add_header("Content-Disposition", "attachment", filename=fileName)
# attach it to root
msgRoot.attach(msgApp)
# close the file handle
fp.close()
# Attach html text
if message:
if embedImages or "mimeType" in kwargs:
msgAlternative.attach(MIMEText(message, kwargs["mimeType"], 'utf-8'))
else:
msgAlternative.attach(MIMEText(message, "plain", 'utf-8'))
