根据单元格值自动发送电子邮件，并根据上一脚本进行调整

import openpyxl
import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

workbook = openpyxl.load_workbook('example.xlsx')
sheet = workbook['Sheet1']
cell_value = sheet['A1'].value

if cell_value == 'send':
    # 邮件设置
    sender_email = 'your_email@example.com'
    receiver_email = 'recipient_email@example.com'
    subject = '自动发送邮件'
    message = '这是一封自动发送的邮件。'
    
    # 创建邮件对象
    msg = MIMEMultipart()
    msg['From'] = sender_email
    msg['To'] = receiver_email
    msg['Subject'] = subject
    
    # 添加邮件内容
    msg.attach(MIMEText(message, 'plain'))
    
    # 发送邮件
    with smtplib.SMTP('smtp.example.com', 587) as server:
        server.starttls()
        server.login(sender_email, 'your_password')
        server.send_message(msg)
        print('邮件发送成功！')

workbook.save('example.xlsx')
workbook.close()
