行动OpenWrt使用GitHubActions构建OpenWrt用法单击按钮创建一个新的存储库。
使用源代码生成.config文件。
（您可以通过工作流文件中的环境变量来更改它。
）将.config文件推送到GitHub存储库。
在“操作”页面上选择“BuildOpenWrt”。
单击Runworkflow按钮。
构建完成后，单击“操作”页面右上角的Artifacts按钮以下载二进制文件。
尖端创建.config文件和构建OpenWrt固件可能需要很长时间。
因此，在创建存储库以构建自己的固件之前，您可以通过来检查其他人是否已经构建了满足您需要。
将您所构建固件的一些元信息（例如固件体系结构和已安装的软件包）添加到存储库简介中，这将节省其他人的时间。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
