小编Uts*_*tel的帖子

我正在尝试学习 asyncio。如果我在没有 asyncio 库的情况下正常运行这个程序，那么它需要更少的时间，而以这种方式需要更多的时间，那么这是使用 asyncio 发送邮件的正确方法还是还有其他方法？

import smtplib 
import ssl
import time
import asyncio


async def send_mail(receiver_email):
    try:
        print(f"trying..{receiver_email}")
        server = smtplib.SMTP(smtp_server, port)
        server.ehlo()
        server.starttls(context=context)
        server.ehlo()
        server.login(sender_email, password)
        message = "test"
        await asyncio.sleep(0)
        server.sendmail(sender_email, receiver_email, message)
        print(f"done...{receiver_email}")
    except Exception as e:
        print(e)
    finally:
        server.quit()

async def main():
     t1 = time.time()
     await asyncio.gather(
         send_mail("test@test.com"),
         send_mail("test@test.com"),
         send_mail("test@test.com"),
         send_mail("test@test.com")
     )
    print(f"End in {time.time() - t1}sec")

if __name__ == "__main__":
     smtp_server = "smtp.gmail.com"
     port = 587  # For starttls
     sender_email = "*****"
     password = …
