python附加电子邮件正文到电子邮件不工作

问题描述 投票：0回答：3

我有一个下面的脚本，它适用于rsync，这个脚本实际上将文件从远程主机拉到服务器，在dest文件夹下运行它。

然而rsync工作正常，但邮件部分基本上msg = 'message + "rsync process completed"'没有作为电子邮件发送。

不知怎的，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 = '[email protected]'
mailTo = '[email protected]'
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")

从上面的脚本输出终端上的结果：

Mail Sent to [email protected]

邮件服务工作正常，但msg变量包含消息msg = message + "rsync process completed"没有得到发送休息邮件与主题是工作，问题看起来是与msg部分没有被调用或正确打开。

只是另一种方式！

虽然我正在应用下面的方法，其中我已经包括To地址，Subject和消息即Rsync Process Completed Successfully.工作和发送电子邮件，但真正的问题再次保持相同，如果我想包括msg或说想在这里披露msg部分，怎么可能这样做！

EmailSender="[email protected]"
EmailReceiver="[email protected]"

msgBody='''From: dnsmailer <[email protected]>
To: To Person <[email protected]>
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)

问题是msg是在sync函数内部计算的（可以在循环中调用）然后只是被遗忘（意思是没有存储）。

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对邮件正文进行传播，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")

你可以尝试使用MIMEMultipart发送消息。我应该这样工作。

import smtplib
from email.mime.multipart import MIMEMultipart

EmailSender = "[email protected]"
EmailReceiver = "[email protected]"

msgBody = '''From: dnsmailer <[email protected]>
To: To Person <[email protected]>
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))

只是冒昧地把电子邮件放在这里对我有用，因为smtplib抛出了我之前申请的一些错误，下面是工作的电子邮件部分，可能有人会寻找相同的:-)

对@Serge和@Vijay有很大的帮助。

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


email_sender = "[email protected]"
email_receiver = "[email protected], [email protected], [email protected]"


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"] = "[email protected]"
    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))
