python將mailBody附加到電子郵件中不起作用

Question

我有一個下面的腳本，它對於rsync正常工作，該腳本實際上將文件從遠程主機拉到服務器，該文件從其在dest Folder下運行。

但是rsync可以正常工作，但是郵件部分msg = 'message + "rsync process completed"'基本上不作為電子郵件發送。

不知何故我不知道我在做什么錯！

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")

從上面的腳本在終端上輸出結果：

 $ ./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 

郵件服務工作正常，但是包含消息msg = message + "rsync process completed"的msg變量未正常發送帶有主題的剩余電子郵件，該問題似乎正在起作用，問題似乎出在msg部分未正確調用或打開的地方。

只是另一種方式！

當我使用下面的方法時，其中包含了To address， Subject和Message即Rsync Process Completed Successfully. 可以正常工作並發送電子郵件，但如果我想包含msg或說要在此處公開msg部分，那么真正的問題仍然是相同的，那怎么辦！

 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)

您能否嘗試使用MIMEMultipart發送消息。 我應該這樣工作。

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))

問題在於， msg是在sync函數內部計算的（可以在循環中調用），然后被遺忘（意味着未存儲）。

因此，當您想在郵件正文中使用它時，它將不再可用。 您必須在可用時使用它並直接調整郵件正文，或者更好地將其存儲在列表中，然后使用它來構建郵件正文。 代碼可能變成：

...
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")

只是隨便放一點對我有用的電子郵件，因為smtplib拋出了我較早應用的一些錯誤，下面是有效的電子郵件部分，可能有人會在找一樣的東西:-)

非常感謝@Serge和@Vijay對此提供幫助。

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))
