python将mailBody附加到电子邮件中不起作用

Question

我有一个下面的脚本，它对于rsync正常工作，该脚本实际上将文件从远程主机拉到服务器，该文件从其在dest Folder下运行。

但是rsync可以正常工作，但是邮件部分msg = 'message + "rsync process completed"'基本上不作为电子邮件发送。

不知何故我不知道我在做什么错！

import os
import sys
import subprocess
import argparse
import smtplib

#Dir Structure
dst = "/infralogs/external_dns_logs"
rsync_user = "root"
mailFrom = 'robo@helisis.com'
mailTo = 'robo@helisis.com'
mailSub = 'Rsync status'
msg = ""

parser = argparse.ArgumentParser()
parser.add_argument("-n","--hosts",dest="hosts",help="enter remote host/hosts name, comma seperated",metavar="HOSTS")
parser.add_argument("-s","--src",dest="source",help="source file/directory",metavar="SOURCE")
parser.add_argument("-e","--exclude",dest="exclude",help="Exclude files/Directories, comma seperated list",metavar="EXCLUDE")

if len(sys.argv) < 7:
    print(len(sys.argv))
    parser.print_help()
    parser.exit()

args = parser.parse_args()

def sync(host,dst):
    exclude = ""
    if not os.path.exists(dst):
        os.mkdir(dst)
    if ',' in args.exclude:
        for excl in args.exclude.split(','):
            exclude = exclude + " --exclude " + excl
        cmd = "rsync -e 'ssh -o StrictHostKeyChecking=no' -auPz %s %s@%s:%s %s/"%(exclude,rsync_user,host,args.source,dst)
    else:
        cmd = "rsync -e 'ssh -o StrictHostKeyChecking=no' -auPz --exclude %s %s@%s:%s %s/"%(args.exclude,rsync_user,host,args.source,dst)
    print(cmd)
    message = cmd
    p = subprocess.Popen(cmd,shell=True)
    p.wait()
    print("DONE")
    msg = message + "rsync process completed"

mailBody = "From: %s\nTo: %s\nSubject: %s\n\n%s" %(mailFrom,mailTo,mailSub,msg)

if ',' in args.hosts:
    for host in args.hosts.split(','):
        dest = dst + "/" + host
        sync(host,dest)
else:
    dest = dst + "/" + args.hosts
    sync(args.hosts,dest)

try:
    Mail = smtplib.SMTP('mailserver.global.helisis.com', 25, 'localhost.helisis.com')
    Mail.sendmail(mailFrom,mailTo,mailBody,msg)
    print("Mail Sent to %s" %(mailTo))
except:
    print("Mail Failed")

从上面的脚本在终端上输出结果：

 $ ./log_rsync -n remote_Server -s /var/log/infoSec/ -e "null" bind.log 0 100% 0.00kB/s 0:00:00 (xfer#1, to-check=7/9) default.log 12769 100% 12.18MB/s 0:00:00 (xfer#2, to-check=6/9) general.log 9553 100% 4.56MB/s 0:00:00 (xfer#3, to-check=5/9) lame-servers.log 663 100% 129.49kB/s 0:00:00 (xfer#4, to-check=4/9) network.log 0 100% 0.00kB/s 0:00:00 (xfer#5, to-check=3/9) notify.log 3286 100% 356.55kB/s 0:00:00 (xfer#6, to-check=2/9) queries.log 578 100% 47.04kB/s 0:00:00 (xfer#7, to-check=1/9) query-errors.log 0 100% 0.00kB/s 0:00:00 (xfer#8, to-check=0/9) sent 176 bytes received 4303 bytes 814.36 bytes/sec total size is 26849 speedup is 5.99 DONE Mail Sent to robo@helisis.com 

邮件服务工作正常，但是包含消息msg = message + "rsync process completed"的msg变量未正常发送带有主题的剩余电子邮件，该问题似乎正在起作用，问题似乎出在msg部分未正确调用或打开的地方。

只是另一种方式！

当我使用下面的方法时，其中包含了To address， Subject和Message即Rsync Process Completed Successfully. 可以正常工作并发送电子邮件，但如果我想包含msg或说要在此处公开msg部分，那么真正的问题仍然是相同的，那怎么办！

 EmailSender="robo@localhost.helisis.com" EmailReceiver="robo@helisis.com" msgBody='''From: dnsmailer <netrobo@helisis.com> To: To Person <robo@helisis.com> Subject: rsync Status from infra-syslog Rsync Process Completed Succesfully. ''' if ',' in args.hosts: for host in args.hosts.split(','): dest = dst + "/" + host sync(host,dest) else: dest = dst + "/" + args.hosts sync(args.hosts,dest) try: smtpobj=smtplib.SMTP('mailserver.global.helisis.com', 25, 'localhost.helisis.com') smtpobj.sendmail(EmailSender,EmailReceiver,msgBody) except Exception as e: print(e)

您能否尝试使用MIMEMultipart发送消息。 我应该这样工作。

import smtplib
from email.mime.multipart import MIMEMultipart

EmailSender = "robo@localhost.helisis.com"
EmailReceiver = "robo@helisis.com"

msgBody = '''From: dnsmailer <netrobo@helisis.com>
To: To Person <robo@helisis.com>
Subject: rsync Status from  infra-syslog

Rsync Process Completed Succesfully.
'''

try:
    Mail = smtplib.SMTP('mailserver.global.helisis.com', 25, 'localhost.helisis.com')
    mail_obj = MIMEMultipart()
    mail_obj["From"] = EmailSender
    mail_obj["To"] = EmailReceiver
    mail_obj["Subject"] = "rsync Status from  infra-syslog."
    mail_obj.preamble = "rsync Status from  infra-syslog. "
    msgBody = "Rsync Process Completed Successfully!"  # Message body
    mail_obj.attach(MIMEText(message, 'plain'))
    Mail.sendmail(from_addr=[EmailSender], to_addrs=[EmailReceiver], msg=mail_obj.as_string())
    print("Mail Sent to %s" % (EmailReceiver))
except Exception as error:
    print("Mail Failed - {}".format(error))

问题在于， msg是在sync函数内部计算的（可以在循环中调用），然后被遗忘（意味着未存储）。

因此，当您想在邮件正文中使用它时，它将不再可用。 您必须在可用时使用它并直接调整邮件正文，或者更好地将其存储在列表中，然后使用它来构建邮件正文。 代码可能变成：

...
def sync(host,dst):
    ...
    message = cmd
    p = subprocess.Popen(cmd,shell=True)
    p.wait()
    print("DONE")
    return message + " rsync process completed"  # returns the msg to the caller

msglist = []             # a list to store the messages for the mail body

if ',' in args.hosts:
    for host in args.hosts.split(','):
        dest = dst + "/" + host
        msglist.append(sync(host,dest))
else:
    dest = dst + "/" + args.hosts
    msglist.append(sync(args.hosts,dest))

msg = "\n".join(msglist)                 # combine all messages, one per line
mailBody = "From: %s\nTo: %s\nSubject: %s\n\n%s" %(mailFrom,mailTo,mailSub,msg)

try:
    Mail = smtplib.SMTP('mailserver.global.helisis.com', 25, 'localhost.helisis.com')
    Mail.sendmail(mailFrom,mailTo,mailBody,msg)
    print("Mail Sent to %s" %(mailTo))
    Mail.bye()                  # cleaner to say goodbye to server...
    Mail.close()
except:
    print("Mail Failed")

只是随便放一点对我有用的电子邮件，因为smtplib抛出了我较早应用的一些错误，下面是有效的电子邮件部分，可能有人会在找一样的东西:-)

非常感谢@Serge和@Vijay对此提供帮助。

from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib


email_sender = "syslogger@helisis.com"
email_receiver = "robo@helisis.com, robo01@helisis.com, robo02@helisis.com"


try:
    Mail = smtplib.SMTP('mailserver.global.helisis.com', 25, 'localhost.helisis.com')
    mail_obj = MIMEMultipart('alternative')
    mail_obj["From"] = email_sender
    mail_obj["To"] = email_receiver
    mail_obj["Cc"] = "someone@helisis.com"
    mail_obj["Subject"] = "rsync Status from  infra-syslog."
    mail_obj.preamble = "rsync Status from  infra-syslog. "
    msgBody = "Rsync Process Completed Successfully!"  # Message body
    mail_obj.attach(MIMEText(msg, 'plain'))
    Mail.sendmail(from_addr=[email_sender], to_addrs=[email_receiver],msg=mail_obj.as_string())
    print("Mail Sent to %s" % (email_sender))
except Exception as error:
    print("Mail Failed - {}".format(error))
