Question

我正在尝试将图像显示为使用Python发送的邮件的一部分。有一个关于Python文档的例子没有用。

from datetime import datetime
import sys

import smtplib

from email.message import EmailMessage
from email.headerregistry import Address
from email.utils import make_msgid



from email.mime.image import MIMEImage

attachment = '/user/file/test.png'


import email.policy
msg = EmailMessage()
msg['To'] = Address("Srujan", 'myemail@example.com')
msg['From'] = Address("Srujan", 'myemail@example.com')
msg['Subject'] = "Nice message goes with it "+str(datetime.now())
id = make_msgid()
msg.set_type('text/html')
msg.set_content(" This is the Data Message that we want to send")
html_msg = "<br> <b><u> This is the Text .... </u></b><br> <img src='cid:{image_id}' />".format(image_id=id[1:-1])
msg.add_alternative(html_msg, subtype="html")
image_data = open(attachment, "rb")
image_mime = MIMEImage(image_data.read())
image_data.close()
msg.add_attachment(image_mime,   cid=id, filename = "myown.png" ,)


try:
    with smtplib.SMTP('example.com') as s:
        s.ehlo()
        s.starttls()
        s.ehlo()

        s.send_message(msg)
        s.close()
    print("Email sent!")
except:
    print("Unable to send the email. Error: ", sys.exc_info()[0])
    raise

我发现了一些事情：

收件人：Srujan＆lt;“myemail@example.com”＆gt;来自：Srujan   ＆LT; “myemail@example.com” ＆GT;主题：好消息与它一起2016-01-21   17：39：23.642762 MIME-Version：1.0 Content-Type：multipart / mixed;   边界= “=============== 3463325241650937591 ==”

这是我们要发送的数据消息

- =============== 0739224896516732414 == Content-Type：text / html; charset =“utf-8”Content-Transfer-Encoding：7bit MIME-Version：1.0


这是文字....

现在附加的消息有两个内容类型值。电子邮件附带文字和无图像

我已成功使用MultiPart类，但希望通过EmailMessage实现这一目标。

关于这个主题的Python文档是不完整/错误真的很遗憾。我想做同样的事情并得到同样的问题（附件有两个内容类型）

在public function Upload($id){ $upload = $this->input->post('fotoDsn'); //Foto Set $photoName = gmdate("d-m-y-H-i-s", time()+3600*7).".jpg"; $config['upload_path'] = './assets/'; $config['allowed_types'] = 'gif||jpg||png'; $config['max_size'] = '2048000'; $config['file_name'] = $photoName; $this->load->library('upload',$config); if($this->upload->do_upload('userfile')){ $upload = 1; } else{ $upload = 2; } if($upload==1){ $data = array( 'foto_dosen'=>$photoName); $update = $this->MDosen->update(array('id'=>$id), $data); if($update){ echo 1; }else{ echo 2; } }//else kalo gagal }个对象上使用function update($cond, $data){ $this->db->where($cond); $query = $this->db->update('dosen', $data); return $query; }方法代替attach()解决了问题。唯一需要注意的是，在执行此操作之前，您必须将add_attachment()转换为EmailMessage类型。一个例子：

EmailMessage

带有Image的Python 3 EmailMessage html消息
