python - 内联图像也被附加

Question

我有一个 Python 脚本，用于发送包含不同数量内联图像的电子邮件，它实际上按预期工作，但有一个异常(exception)。每张图片也作为附件发送，使每张图片出现两次。即使在禁用脚本的许多部分后，我也无法找到导致重复的原因。

 !/usr/bin/python
   coding: utf-8

   import os, sys
   import mimetypes
   from email.MIMEMultipart import MIMEMultipart
   from email.MIMEText import MIMEText
   from email.MIMEImage import MIMEImage
   from email.mime.base import MIMEBase
   from email import encoders import smtplib

   try:
 strTo = ‘’’Joe@Email.com’’’
 strFrom = ‘’’Jim@Some.biz’’’

 msg = MIMEMultipart()
 msg['Subject'] = ‘’’Photo Test’’’
 msg['From'] = '''Jim@Some.biz'''
 msg['Reply-to'] = '''Jim@Some.biz'''
 msg['To'] = ‘’’Joe@Email.com’’’
 msg.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 email agents can decide which they want to display.
 msgAlternative = MIMEMultipart('alternative')
 msg.attach(msgAlternative)
 msgText = MIMEText(''' words here, then the image followed by more words here''', 'plain')
 msgAlternative.attach(msgText)
 msgText = MIMEText('''<p>words here, then the image</p><p><img src="cid:image1"></p><p>followed by more words here</p><p></p>''','html')
 msgAlternative.attach(msgText)
 # Attach Any Images
 if '''/Users/jim/Desktop/003.jpg''' != "":
     images = '''/Users/jim/Desktop/003.jpg'''.splitlines()
     i=1
     for image in images:
         # print 'Image',i,': ',image,'\n'
         fp = open(image, 'rb')
         msgImage = MIMEImage(fp.read())
         fp.close()
         # Define the image's ID as referenced above
         msgImage.add_header('Content-ID', '<image'+str(i)+'>')
         msg.attach(msgImage)
         i+=1

  #send the email
 smtp = smtplib.SMTP_SSL(‘’’mailserver.net''', '''465''') 
 smtp.ehlo() 
 smtp.login('''Jim@Some.biz''', ‘’’xxxxxx’’’)
 smtp.sendmail(strFrom,strTo.split(","), msg.as_string())
 smtp.quit() except: print("Sending Error : "+strTo)

如何防止图像附件？

Answer 1

简单的解决方案，一旦找到:

msg = MIMEMultipart()

应该是

msg = MIMEMultipart('related')
