脚本过于简单,供学习和参考。主要了解一下smtplib库的使用和超时机制的实现。使用signal.alarm实现超时机制。

example:
from emailtest import emailtest

eb = emailtest.EmailObject("******@******.com","test content")
eb.send_email()
tips:
increase timeout:
  eb.timeout = 10
increase retry times:
  eb.retry = 5
'''

配置文件参考如下:

[default]
from_addr = ******@******.com
password = ******
smtp_server = smtp.******.com
[163]
from_addr = ******@163.com
password = ******
smtp_server = smtp.163.com
[qq]
from_addr = ******@qq.com
password = ******
smtp_server = smtp.qq.com

以上这篇利用python实现简单的邮件发送客户端示例就是小编分享给大家的全部内容了,希望能给大家一个参考,也希望大家多多支持。

P70系列延期,华为新旗舰将在下月发布

3月20日消息,近期博主@数码闲聊站 透露,原定三月份发布的华为新旗舰P70系列延期发布,预计4月份上市。

而博主@定焦数码 爆料,华为的P70系列在定位上已经超过了Mate60,成为了重要的旗舰系列之一。它肩负着重返影像领域顶尖的使命。那么这次P70会带来哪些令人惊艳的创新呢?

根据目前爆料的消息来看,华为P70系列将推出三个版本,其中P70和P70 Pro采用了三角形的摄像头模组设计,而P70 Art则采用了与上一代P60 Art相似的不规则形状设计。这样的外观是否好看见仁见智,但辨识度绝对拉满。
