我正在使用 Django 的电子邮件模块来触发带有嵌入图像的电子邮件。目前，我的静态文件夹中有该图像。我尝试直接在python中使用html代码来触发电子邮件。但是图像没有嵌入到触发的电子邮件中。我已经尝试将图像源属性指定为静态路径和 url。有人可以帮忙吗？下面是我使用的代码。
法典：
recipient_list = ['a...@gmail.com']
from_email = 'a...@gmail.com'
message = ''
path = "{% static 'images/Welcome_image.jpg' %}" //Using this image in the below html also tried specifying the source as an url that points to the url path. Like https://abc/images/Welcome_imagr.jpg
message += "<table border='1' cellpadding='1' cellspacing='0' width='800'>
<tbody>
<tr>
<td height='506'>
<table border='0' cellpadding='0' cellspacing='0' width='600'>
<tbody>
<tr>
<td valign='top'>
<img height='190' src=%s width='800' tabindex='0'> //Using this image here but it is not rendered properly.
</td>
</tr>
<tr>
<td height='306' valign='top'>
<table cellpadding='0' cellspacing='20' width='800'>
<tbody>
<tr>
<td align='left' height='804' style='font-family:arial,helvetica,sans-serif;font-size:13px' valign='top'>Hi User,<br><br>
Welcome to the world.
</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>

</td>
</tr>
</tbody>
</table>"%(path)
subject = "Welcome to the place!"
try:
msg = EmailMessage(subject, message, from_email, recipient_list)
msg.content_subtype = "html" # Main content is now text/html
if any(recipient_list):
msg.send()
except Exception:
print("Exception while sending mail")
我尝试了以下代码，它起作用了：
蟒：
def send((：
msg = EmailMessage()
# generic email headers
msg['Subject'] = 'Welcome'
msg['From'] = 'abc@gmail.com'
recipients = ['abc@gmail.com']
# 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='')
# if `domain` argument isn't provided, it will
# use your computer's name
# set an alternative html body
msg.add_alternative("""
<html>
<body>
