通过Amazon SES向多个人发送电子邮件时发生AttributeError

问题描述

我的目标是向多个收件人发送电子邮件。当我只在RECIPIENT变量中给一封电子邮件并提供Destinations = [RECIPIENT]时，代码将运行，但是当我使用以下代码给多封电子邮件时，它将给出错误
“ AttributeError：'list'对象没有属性'encode'” 任何指针都值得赞赏。

RECIPIENT = "[e-mail] [e-mail]"
res = list(RECIPIENT.split(" "))

BODY_TEXT = email_message
client = boto3.client('ses',region_name=region)
# Create a multipart/mixed parent container.
msg = MIMEMultipart('mixed')
# Add subject,from and to lines.
msg['Subject'] = SES_subject
msg['From'] = SENDER
msg['To'] = res

msg_body = MIMEMultipart('alternative')
textpart = MIMEText(BODY_TEXT.encode(CHARSET),'plain',CHARSET)

# Add the text and HTML parts to the child container.
msg_body.attach(textpart)
msg.attach(msg_body)
if suite_Failed_data:
    att = MIMEApplication(open(ATTACHMENT,'rb').read())
    att.add_header('Content-disposition','attachment',filename=os.path.basename(ATTACHMENT))
    msg.attach(att)

try:
    # Provide the contents of the email.
    response = client.send_raw_email(
        Source=SENDER,Destinations=res,RawMessage={
            'Data': msg.as_string(),},)
# display an error if something goes wrong.
except ClientError as e:
    logger.exception(e)
else:
    logger.info("Email sent!")
