Python通过电子邮件发送了PDF文件，但没有nam

Question

我发现并扩展了一个脚本，该脚本将扫描目录，然后通过电子邮件发送其中的PDF。当我收到电子邮件时出现问题。PDF将作为不带扩展名的“noname”文件到达。我必须下载它们并手动添加扩展来显示它们。我有什么遗漏吗？？在

import sys
import os
import smtplib
from email import encoders
from email.mime.base import MIMEBase
from email.mime.multipart import MIMEMultipart

COMMASPACE = ', '

def main():
    sender = 'jp@voice.com'
    password = 'pword'
    recipients = 'j@gmail.com'

    # Create enclosing (outer) message
    outer = MIMEMultipart()
    outer['Subject'] = 'TEST EMAIL'
    outer['To'] = COMMASPACE.join(recipients)
    outer['From'] = sender
    outer.preamble = 'You will not see this in a MIMIE aware reader'

    # list of attachments
    attachments = r'C:/Users/Ace/Desktop/PDFTST/'
    attach = os.listdir(attachments)
    for file in attach:
        try:
            with open(attachments + file, 'rb') as fp:
                msg = MIMEBase('application', "octet-stream")
                msg.set_payload(fp.read())
            encoders.encode_base64(msg)
            outer.attach(msg)
        except:
            print("unable to open the attach. Error: ", sys.exc_info()[0])
            raise

        composed = outer.as_string()

    try:
        with smtplib.SMTP('smtp.gmail.com', 587) as s:
            s.ehlo()
            s.starttls()
            s.ehlo()
            s.login(sender, password)
            s.sendmail(sender, recipients, composed)
            s.close()
        print("email sent!!!!")
    except:
        print("Unable to send email. Error: ", sys.exc_info()[0])
        raise

if __name__ == '__main__':
    main()

Answer 1

我认为应该将MIME类型设置为application/pdf，而不是application/octet stream。在

指定如下文件名：

 msg.add_header('Content-Disposition', 'attachment', filename=filename)

Answer 2

乔的评论修正了我在文本文件中遇到的类似情况。对于您的示例，请键入：

msg = MIMEBase('application', "pdf", Name=file)
