如何将python脚本的输出发送到电子邮件地址

Question

我有一个线程python脚本,在局域网上ping 20个节点,并打印出每个节点的状态:节点是活动的,节点是关闭的等等.我想将此输出发送到我的电子邮件帐户,因为我打算让这个脚本每周运行一次,就自己而言,如果我离开局域网我不用担心,我可以查看我的电子邮件.

语言:蟒蛇.操作系统:Linux Mint 10 Julia.谢谢

Answer 1

如果它每周运行一次,你可能会从crontab运行它？

30 2 * * 5  python yourScript.py | mail -s outputFromScript your@email.address

Answer 2

看一下 logging 和 logging.config，我之前使用过它来接收来自后台运行的脚本的错误消息

http://docs.python.org/library/logging.html

例如

import logging
import logging.config

logDir = "./logs/"

logging.config.fileConfig(logDir+'logging.conf')
logger = logging.getLogger('email')

logger.debug('THIS IS A DEBUG MESSAGE')
logger.error('THIS IS AN ERROR')

然后是logging.conf

[loggers]
keys=root,email

[logger_root]
level=DEBUG
handlers=rotatingFileHandler

[logger_email]
level=ERROR
handlers=email
qualname=email

[formatters]
keys=emailFormatter,rotatingFormatter

[formatter_emailFormatter]
format=%(asctime)s %(name)-12s %(levelname)-8s %(message)s

[formatter_rotatingFormatter]
format=%(asctime)s %(name)-12s %(levelname)-8s %(message)s
datefmt=%m-%d %H:%M

[handlers]
keys=email,rotatingFileHandler

[handler_email]
class=handlers.SMTPHandler
level=ERROR
formatter=emailFormatter
args=('mail.xxx','x@x.com',['y@y.com',],'ERROR!',('x@x.com','xxx'))

[handler_rotatingFileHandler]
class=handlers.RotatingFileHandler
level=DEBUG
formatter=rotatingFormatter
args=('./logs/log.out', 'maxBytes=1000000', 'backupCount=5')

从上面我会在我的电子邮件中收到“这是一个错误”。

print您可以使用 alogger打印到粗壮和记录器，而不是让您的主要输出

您可以根据Logging Cookbook如下设置记录器：

import logging
log_file = r'C:\Users\user\Downloads\LogFileName.log'

logger = logging.getLogger('simple_example')
logger.setLevel(logging.INFO)

# create file handler which logs even debug messages
fh = logging.FileHandler('log_file')
fh.setLevel(logging.DEBUG)
# create console handler with a higher log level
ch = logging.StreamHandler()
ch.setLevel(logging.INFO)
# create formatter and add it to the handlers
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
ch.setFormatter(formatter)
fh.setFormatter(formatter)
# add the handlers to logger
logger.addHandler(ch)
logger.addHandler(fh)

现在在print您的脚本中替换为logger.info

之前的例子：

print("Printing status")

之后的示例：

logger.info("Printing status")

然后您可以通过电子邮件将日志发送给自己，如下所示：

import smtplib
from email.message import EmailMessage
import os
msg_body = "Body Text"

msg = EmailMessage()

msg['Subject'] = "Subject"
msg['From'] = "send_from@email.com"
msg['To'] = "send_to@email.com"

msg.set_content(msg_body)

if os.path.isfile(log_file):
        msg.add_attachment(open(log_file, "r").read(), filename=os.path.basename(log_file))


# Send the message via our own SMTP server.
s = smtplib.SMTP("smtpa.server")
s.send_message(msg)
s.quit()

使用smtplib.他们提供的例子相当不错.

import smtplib

def prompt(prompt):
    return raw_input(prompt).strip()

fromaddr = prompt("From: ")
toaddrs  = prompt("To: ").split()
print "Enter message, end with ^D (Unix) or ^Z (Windows):"

# Add the From: and To: headers at the start!
msg = ("From: %s\r\nTo: %s\r\n\r\n"
       % (fromaddr, ", ".join(toaddrs)))
while 1:
    try:
        line = raw_input()
    except EOFError:
        break
    if not line:
        break
    msg = msg + line

print "Message length is " + repr(len(msg))

server = smtplib.SMTP('localhost')
server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
