我有以下功能(Django的)發出邀請:Gmail中不顯示嵌入式圖像的
def send_invitation(self, request):
t = loader.get_template('email/invitation.html')
html_content = t.render(Context(context))
message = EmailMessage('Hi there', html_content, '[email protected]',
[self.profile_email],
headers={'Reply-To': 'Online <[email protected]>'})
message.content_subtype = 'html'
localize_html_email_images(message)
message.send()
我用一個函數來替代鏈接的圖像附帶的圖像本地提供。
def localize_html_email_images(message):
import re, os.path
from django.conf import settings
image_pattern = """<IMG\s*.*src=['"](?P<img_src>%s[^'"]*)['"].*\/>""" % settings.STATIC_URL
image_matches = re.findall(image_pattern, message.body)
added_images = {}
for image_match in image_matches:
if image_match not in added_images:
img_content_cid = id_generator()
on_disk_path = os.path.join(settings.STATIC_ROOT, image_match.replace(settings.STATIC_URL, ''))
img_data = open(on_disk_path, 'r').read()
img = MIMEImage(img_data)
img.add_header('Content-ID', '<%s>' % img_content_cid)
img.add_header('Content-Disposition', 'inline')
message.attach(img)
added_images[image_match] = img_content_cid
def repl(matchobj):
x = matchobj.group('img_src')
y = 'cid:%s' % str(added_images[matchobj.group('img_src')])
return matchobj.group(0).replace(x, y)
if added_images:
message.body = re.sub(image_pattern, repl, message.body)
所有工作都很完美。但不知何故,Gmail在Hotmail和Outlook不會立即顯示圖像。
當我檢查電子郵件的來源它確實增加了正確的頭:
Content-Type: multipart/mixed; boundary="===============1839307569=="
#stuff
<IMG style="DISPLAY: block" border=0 alt="" src="cid:A023ZF" width=600 height=20 />
#stuff
Content-Type: image/jpeg
MIME-Version: 1.0
Content-Transfer-Encoding: base64
Content-ID: <A023ZF>
Content-Disposition: inline
我能做些什麼,立即讓Gmail顯示圖片打開,就像Hotmail和Outlook中的電子郵件時?
PS。我查看了關於內嵌圖像的所有主題,但仍然無法在Gmail中工作
