from typing import List

import yagmail
from jinja2 import Template

def send_email(
        email_to: List[str],
        title: str,
        html: str,
) -> None:
    yag = yagmail.SMTP(
        host=""smtp.163.com"", user="test@163.com",
        password="PASSWORD"
    )
    response = yag.send(to=email_to, subject=title, contents=html)
    print(f"邮件发送结果: {email_to} {response}")


def send_test_email(email_to: List[str]) -> None:
    project_name = settings.PROJECT_NAME
    subject = f"{project_name} - A important email"
    
    with open("test_email.html") as f:
        tm = Template(f.read())

    msg = tm.render({"project_name": project_name, "email": email_to})

    send_email(
        email_to=email_to,
        title=subject,
        html=msg
    )


if __name__ == '__main__':
    send_test_email(['cloud74521941@163.com', 'cloud_0805@163.com'])
