好的,以下是用Python实现自动定时发送邮件的代码,实现了以上三个功能:
```python
import smtplib
import os
import time
import schedule
import openpyxl
import matplotlib.pyplot as plt
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage
from email.mime.application import MIMEApplication
# 邮件发送人和收件人
sender = 'your_email@example.com'
receiver = 'recipient_email@example.com'
# 邮件主题和正文
subject = 'Test Email'
content = 'This is a test email.'
# 附件文件名和路径
filename = 'data.xlsx'
filepath = '/path/to/file/'
# 图表文件名和路径
chartname = 'chart.png'
chartpath = '/path/to/chart/'
def generate_chart():
# 生成图表
data = [1, 2, 3, 4, 5]
plt.plot(data)
plt.savefig(chartpath + chartname)
def send_email():
# 生成附件和图表
generate_chart()
attachment = MIMEApplication(open(filepath + filename, 'rb').read())
attachment.add_header('Content-Disposition', 'attachment', filename=filename)
with open(chartpath + chartname, 'rb') as f:
img_data = f.read()
image = MIMEImage(img_data)
image.add_header('Content-ID', '<chart>')
# 构造邮件
msg = MIMEMultipart()
msg['From'] = sender
msg['To'] = receiver
msg['Subject'] = subject
msg.attach(MIMEText(content))
msg.attach(attachment)
msg.attach(image)
# 发送邮件
try:
smtp = smtplib.SMTP('smtp.example.com')
smtp.login(sender, 'password')
smtp.sendmail(sender, receiver, msg.as_string())
print('Email sent successfully.')
smtp.quit()
except Exception as e:
print('Email send failed:', e)
# 设置定时任务
schedule.every().day.at('10:00').do(send_email)
while True:
schedule.run_pending()
time.sleep(1)
```
以上代码使用了Python的`schedule`模块实现定时任务,并使用了`openpyxl`和`matplotlib`模块生成Excel文件和图表,使用了`email`和`smtplib`模块发送邮件。在`send_email`函数中,首先生成附件和图表,然后构造邮件并发送邮件。其中,图表被以`Content-ID`的形式嵌入到邮件正文中。
