python向多个用户发送文字、图片内容邮件和excel附件

话不多说，直接上代码，需要把发件里面的smtp_info替换为自己的信息，其中password是指邮箱在开通POP/SMTP功能后获取的授权码！
import smtplib  
from email.mime.multipart import MIMEMultipart  
from email.mime.text import MIMEText  
from email.mime.image import MIMEImage  
from email.mime.base import MIMEBase  
from email import encoders  


smtp_info = {
    'smtp_server': 'smtp.qq.com',  # 替换为对应的邮件服务器，这是qq的，还有smtp.163.com等
    'port': 465,
    'sender_email': 'lytcreate@qq.com',  # 替换为发件邮箱账号
    'password': 'xxxxxxxxxxxxxxxx',  # 替换为你自己的授权码
    'receivers': ['lytcreate@163.com', 'lytcreat@163.com']  # 替换为接收人邮箱
}

def send_main(smtp_info, subject, content, img_path, excel_path):
    # 设置SMTP服务器地址和端口
    smtp_server = smtp_info['smtp_server']
    port = smtp_info['port']  # 587:使用TLS加密, 465:SSL
    # 设置发件人和收件人信息
    sender_email = smtp_info['sender_email']  # 替换为你的QQ邮箱地址
    password = smtp_info['password']  # 替换为你的QQ邮箱授权码
    receivers = smtp_info['receivers']  # 替换为接收者的邮箱地址列表

    # 创建邮件对象
    message = MIMEMultipart()
    message['From'] = sender_email
    message['To'] = ', '.join(receivers)
    message['Subject'] = subject

    mail_body = f"""

    </body>

    """
    message.attach(MIMEText(mail_body, 'html'))

    # 添加图片到邮件正文
    with open(img_path, 'rb') as f:  # 替换为你的图片路径
        img_data = f.read()
        img = MIMEImage(img_data, name=img_path.split('/')[-1])
        img.add_header('Content-ID', '<image1>')  # 设置Content-ID以便在HTML中引用
        message.attach(img)

        # 添加Excel文件作为附件
    with open(excel_path, 'rb') as f:  # 替换为你的Excel文件路径
        attachment = MIMEBase('application', 'vnd.openxmlformats-officedocument.spreadsheetml.sheet')
        attachment.set_payload(f.read())
        encoders.encode_base64(attachment)
        attachment.add_header('Content-Disposition', 'attachment', filename=excel_path.split('/')[-1])  # 附件在邮件中的名称
        message.attach(attachment)

        # 发送邮件
    try:
        if port == 587:
            server = smtplib.SMTP(smtp_server, port)
            server.starttls()  # 端口为587时启动TLS模式
        else:
            server = smtplib.SMTP_SSL(smtp_server, port)
        server.login(sender_email, password)  # 登录到你的邮箱
        text = message.as_string()
        server.sendmail(sender_email, receivers, text)  # 发送邮件给多个接收者
        print('Email sent successfully!', subject)

    except Exception as e:
        print(f'Failed to send email: {e}', subject)


if __name__ == '__main__':
    subject = 'Python自动化测试报告'  # 邮件主题
    content = '这是一些测试内容'  # 邮件文字内容
    img_path = '123.jpg'      # 邮件正文图片
    excel_path = '123.xlsx'   # 邮件附件excel
    send_main(smtp_info, subject, content, img_path, excel_path)
