Python3实现带附件的定时发送邮件功能

要实现带附件的定时发送邮件功能，我们需要使用Python的smtplib和email库，以下是详细步骤：

1、安装所需库

确保已经安装了Python的smtplib和email库，如果没有安装，可以使用以下命令安装：

“`

pip install securesmtplib

pip install email

“`

2、编写代码

导入所需库

“`python

import smtplib

from email.mime.multipart import MIMEMultipart

from email.mime.text import MIMEText

from email.mime.base import MIMEBase

from email import encoders

import os

import schedule

import time

“`

设置邮箱账户信息

“`python

from_email = "your_email@example.com"

password = "your_password"

to_email = "recipient_email@example.com"

“`

创建邮件对象

“`python

msg = MIMEMultipart()

msg[‘From’] = from_email

msg[‘To’] = to_email

msg[‘Subject’] = "邮件主题"

“`

添加邮件正文

“`python

body = "邮件正文内容"

msg.attach(MIMEText(body, ‘plain’))

“`

添加附件

“`python

filename = "path/to/your/attachment"

attachment = open(filename, "rb")

part = MIMEBase(‘application’, ‘octetstream’)

part.set_payload((attachment).read())

encoders.encode_base64(part)

part.add_header(‘ContentDisposition’, "attachment; filename= %s" % filename)

msg.attach(part)

“`

发送邮件

“`python

def send_email():

server = smtplib.SMTP(‘smtp.gmail.com’, 587)

server.starttls()

server.login(from_email, password)

text = msg.as_string()

server.sendmail(from_email, to_email, text)

server.quit()

“`

设置定时任务

“`python

def job():

send_email()

print("邮件已发送")

schedule.every().day.at("10:30").do(job)

“`

运行定时任务

“`python

while True:

schedule.run_pending()

time.sleep(1)

“`

3、运行代码

将以上代码保存为一个.py文件，然后运行该文件，每天的10:30，程序将自动发送一封带附件的邮件。
