python压缩文件夹然后在发送邮件_python实现定时压缩指定文件夹发送邮件

要实现定时压缩指定文件夹并发送邮件，可以使用Python的zipfile和smtplib库。

以下是一个示例代码：

import zipfile
import smtplib
import os
import time
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email.mime.text import MIMEText
from email.utils import COMMASPACE
from email import encoders

# 定义要压缩的文件夹路径和邮件相关参数
folder_to_compress = '/path/to/folder'
zip_filename = 'compressed.zip'
email_subject = 'Compressed Folder'
email_body = 'Please find the compressed folder attached.'
smtp_server = 'smtp.example.com'
smtp_port = 587
smtp_username = 'example@example.com'
smtp_password = 'password'
sender = 'example@example.com'
recipient = 'recipient@example.com'
send_time = '08:00'

# 压缩文件夹
def zip_folder(folder_path, output_path):
    with zipfile.ZipFile(output_path, 'w', zipfile.ZIP_DEFLATED) as zipf:
        for root, dirs, files in os.walk(folder_path):
            for file in files:
                zipf.write(os.path.join(root, file))

# 发送邮件
def send_email(subject, body, attachment_path, smtp_server, smtp_port, smtp_username, smtp_password, sender, recipient):
    msg = MIMEMultipart()
    msg['From'] = sender
    msg['To'] = recipient
    msg['Subject'] = subject

    msg.attach(MIMEText(body))

    with open(attachment_path, 'rb') as f:
        part = MIMEBase('application', 'octet-stream')
        part.set_payload(f.read())
        encoders.encode_base64(part)
        part.add_header('Content-Disposition', 'attachment', filename=os.path.basename(attachment_path))
        msg.attach(part)

    smtp = smtplib.SMTP(smtp_server, smtp_port)
    smtp.starttls()
    smtp.login(smtp_username, smtp_password)
    smtp.sendmail(sender, recipient, msg.as_string())
    smtp.quit()

# 定时发送邮件
while True:
    current_time = time.strftime('%H:%M')
    if current_time == send_time:
        zip_folder(folder_to_compress, zip_filename)
        send_email(email_subject, email_body, zip_filename, smtp_server, smtp_port, smtp_username, smtp_password, sender, recipient)
        os.remove(zip_filename)
    time.sleep(60)

该代码会每分钟检查一次当前时间，如果与设定的发送时间一致，就压缩指定文件夹并发送邮件。注意，这个代码运行时会一直循环，需要手动关闭。

请注意，这只是一个示例代码，需要根据实际情况进行调整。
