AttributeError：通过 Python 发送 Excel 附件时，“列表”没有属性“编码”

Question

My code is as below.我的代码如下。 The "attachment" variable is returning a static file name for testing "excel/test.xlsx" “附件”变量返回用于测试“excel/test.xlsx”的 static 文件名

def send_email(snapshot_id, email):
    logging.info("Sending_email for snapshot_id %d to user %s", snapshot_id, email)

    attachment = get_attachment(snapshot_id, email)
    logging.info("Sending attachment %s", attachment)

    message = MIMEMultipart("alternative")
    message["Subject"] = "multipart test"
    message["From"] = sender
    message["To"] = email
    message['Date'] = formatdate(localtime=True)

    # write the plain text part
    text = """\
    This is an automated email from the ARIEL reporting database, detailing key changes to Regulatory Tracking data for products, markets and categories you have subscribed to.
    """
    # write the HTML part
    html = """\
    <html>
      <body>
        <p>Hi,<br>
           Check out the changes!!</p>       
        <p> Feel free to <strong>let us</strong> know what content would be useful for you!</p>
      </body>
    </html>
    """
    # convert both parts to MIMEText objects and add them to the MIMEMultipart message
    part1 = MIMEText(text, "plain")
    part2 = MIMEText(html, "html")
    message.attach(part1)
    message.attach(part2)

    part3 = MIMEBase('application', "octet-stream")
    part3.set_payload(open(attachment, "rb").read())
    encoders.encode_base64(part3)
    part3.add_header('Content-Disposition', 'attachment; filename="' + attachment + '"')
    message.attach(part3)

    # send your email
    with smtplib.SMTP(smtp_server, port) as server:

        server.sendmail(
            sender, email, message.as_string()
        )

I am getting this error message:我收到此错误消息：

AttributeError: 'list' object has no attribute 'encode'

Answer 1

Check the line检查线路

message["To"] = email

You may be setting the To header to a list of strings instead of a string.您可能将To header 设置为字符串列表而不是字符串。
