Blog 优化记录
刚开始购买域名后就直接使用了国外空间，后面想再换回来时已经不支持.me域名备案了，现在也只能继续使用。无法备案因此无法使用国内CDN，只能使用Cloudflare，但国内访问还是不太好。
本想找图床存放文章里面的图片，后面看到可使用 Github + Jsdelivr 免费CDN方式保存，并以此方法来保存CSS，Js和Google fonts等静态文件来加速博客访问。修改functions.php将部份加载缓慢静态文件全部替换为Jsdelivr，目前加载比以前快多了.
使用如下方式进行引用资源
https://cdn.jsdelivr.net/gh/你的用户名/你的仓库名@发布的版本号/文件路径
https://cdn.jsdelivr.net/gh/Lsanme/wp-img@master/images/T11-2020.jpgmaster分支会有缓存，缓存应该是一天更新一次。如果想进行及时更新，可以将master修改为latest即可.
通过如下方式，禁用了WP-emoji, WP-embed JS和更换为加载CDN jq

remove_action( 'wp_head', 'print_emoji_detection_script', 7 );

Warning: Cannot modify header information - headers already sent by (output started at /public_html/wp-content/plugins/aph-prism-highlighter/includes/aphph-admin-editor.php:162) in /public_html/wp-includes/pluggable.php on line 1281
Warning: Cannot modify header information - headers already sent by (output started at /public_html/wp-content/plugins/aph-prism-highlighter/includes/aphph-admin-editor.php:162) in /public_html/wp-includes/pluggable.php on line 1284 先停用APH Prism Syntax Highlighter插件，根据错误提示去“插件编辑器”选择APH Prism Syntax Highlighter插件。
选择inclides→aphph-admin-editor.php 找到错误提示的第162行，进行注释掉。
//echo '<span id="aphph-json-user-options" style="display:none">'.json_encode($this->options).'</span>';修改首页文章添加分隔线，F12调试里查看样式，在CSS代码里article面添加”.article-after-content” 样式，并找到需要修改template-parts目录下content.php。添加在</div><!– .after-content –>后
<div class="article-after-content">
</div><!-- .article-after-content -->.article-after-content {
border-bottom: double;
transform:scale(1,1);
border-color: #A81010;
margin-bottom: 30px;
}由于继续使用的经典编辑器，没有必要加载block libary，WordPress 5.0+ remove block-library CSS
//WordPress 5.0+ remove block-library CSS
add_action( 'wp_enqueue_scripts', 'fanly_remove_block_library_css', 100 );
function fanly_remove_block_library_css() {
wp_dequeue_style( 'wp-block-library' );
}修改屏蔽登录页面,Location可以修改为任意地址
// Redirect to home page.
add_action('login_enqueue_scripts','login_protection');
function login_protection(){
if($_GET['admin'] != 'lsan')header('Location: https://www.lsan.me/');
}登录地址就是
https://www.xxxx.com/wp-login.php?admin=lsan
