Python sendmail 与文本文件内容

Question

我想通过 python 脚本发送邮件，我需要它来提醒我一些丢失的文件。

scripy 必须读取日志文件(*.txt)并将该文件的内容发送到我的邮件中，所以我做到了:

import smtplib, os
from email.mime.text import MIMEText


raport_file = open('alert.txt','rb')
alert_msg = MIMEText(raport_file.read().encode("utf-8"), 'plain', 'utf-8')
raport_file.close()




m = smtplib.SMTP()
m.connect("*****", 25)
m.sendmail("Check_Files", "*****", alert_msg.as_string())
m.quit()

脚本运行，但根本没有邮件。如果我用“任何文本”替换alert_msg.as_string()，一切正常。

import smtplib
import base64
import os
import sys

FROM = 'user@user.com'
TO = 'user@user.com'
MARKER = 'SIMPLE_MARKER_GOES_HERE'

if __name__ == "__main__":
    filename = 'name_of_file'

    # Read a file and encode it into base64 format
    fo = open(filename, "rb")
    filecontent = fo.read()
    encodedcontent = base64.b64encode(filecontent)  # base64
    filename = os.path.basename(filename)

    body ="""
Insert whatever message you want here or dynamically create.
"""

    # Define the main headers.
    part1 = """From: Matt Vincent <matt.vincent@jax.org>
To: %s
Subject: Sending Attachment

Content-Type: multipart/mixed; boundary=%s
--%s
""" % (TO, MARKER, MARKER)

    # Define the message action
    part2 = """Content-Type: text/plain
Content-Transfer-Encoding:8bit

%s
--%s
""" % (body, MARKER)

    # Define the attachment section
    part3 = """Content-Type: multipart/mixed; name=\"%s\"

    message = part1 + part2 + part3

    try:
        smtpObj = smtplib.SMTP('domainhere')
        smtpObj.sendmail(FROM, TO, message)
        print "Successfully sent email"
    except Exception:
        print "Error: unable to send email"
