简介：前言因为经常捣鼓网站，有时候会直接在服务器上热更新，这样会导致用户体验很不好这时我们可以设置一个维护通知页面，告知访问的用户正在维护，防止用户因无法访问放弃访问本站效果教程本教程基于Joe主题，当然其他Typecho主题也可以使用，代码是固定的，但是方法是灵活的，期待您的灵感大爆发🥰添加后台开关这里我们可以在主题目录下的 functions.php里添加以下代码 - 隐藏 - 添加全局跳转在public/header.php顶部添加以下代码如果你只想某些页面跳转，比如只想跳转首页，你可以在index.php添加下面的代码 - 隐藏 - 维护页面下载下面的文件，上传到Typecho主程序的根目录，记得把文件名改为 Maintain.html注意：不是 主题 根目录 - 隐藏 -
