一步到位：用Python实现PC屏幕截图并自动发送邮件，实现屏幕监控

在当前的数字化世界中，自动化已经成为我们日常生活和工作中的关键部分。它不仅提高了效率，还节省了大量的时间和精力。在这篇文章中，我们将探讨如何使用Python来实现一个特定的自动化任务 - PC屏幕截图自动发送到指定的邮箱。

这个任务可能看起来很复杂，但是通过Python，我们可以将其分解为几个简单的步骤并逐一实现。首先，我们需要一个能够捕获屏幕截图的工具。其次，我们需要一个能够发送电子邮件的服务。最后，我们需要将这两个步骤组合在一起，创建一个可以自动执行这些任务的脚本。

在本文中，我们将详细介绍这个过程，并提供相应的Python代码示例。无论你是Python初学者，还是寻求新的自动化项目的经验开发人员，都可以从中受益。让我们开始吧。

主要功能

1.通过使用pyautogui库来进行屏幕截图。

2.使用smtplib库来发送电子邮件，以将截图发送给收件人。

3.使用tkinter库创建一个简单的图形用户界面（GUI），用于配置应用程序的设置。

4.通过使用logging库来记录日志，将日志保存到文件中。

5.使用configparser库来读取和保存应用程序的配置设置。

6.实现了开机自动启动功能，可以将应用程序设置为开机自动启动。

7.实现了隐藏和显示应用程序窗口的功能。

8.收件邮箱默认等于发件邮箱。

此外，代码还实现了一些其他功能，如数据加密和解密、删除已发送的截图文件等。

应用程序在为用户提供一个便捷的方式来定时截图并将截图发送给指定的收件人，适用于需要定期截图的监控、远程监视等场景。用户可以通过图形界面设置截图的间隔时间、截图的次数、发件人和收件人的电子邮件地址等。

打开CMD,输入python ScreenCaptureSendEmail.py

我们输入发件邮箱，发件邮箱密码（QQ邮箱则是授权码），截图间隔时间，发送截图数量，然后点击开始截图，稍后我们会收到一封QQ邮件

如下图所示

在本文中，我们详细讨论了如何使用Python实现PC屏幕截图并自动发送至邮箱的功能。我们探讨了相关库的使用。并通过编写实际的代码，我们一步步演示了如何将这些功能整合在一起。希望这篇文章能够帮助你在自动化处理任务、提高工作效率方面取得进步。如果你在实践过程中遇到任何问题，或者有任何建议，欢迎随时与我交流。记住，编程就是解决问题的艺术，不断学习和实践才能更好地掌握它。
