使用function和php实现外链跳转

前言
之前外链跳转使用的是果核的插件,现在不想用插件了,于是自己弄了个代码

教程
首先在子主题的function.php中添加如下代码

//外链跳转 function convert_external_links_to_base64($content) { // 使用正则表达式找到所有外部链接 $pattern = '/<a\s+href=["\'](http[s]?:\/\/[^"\']+)["\']/i'; $content = preg_replace_callback($pattern, function($matches) { $url = $matches[1]; // 对 URL 进行 Base64 编码 $base64_url = base64_encode($url); // 返回新的链接,指向中间页 return str_replace($url, site_url('/redirect.php?url=' . $base64_url), $matches[0]); }, $content); return $content; } // 将函数应用于文章和页面内容 add_filter('the_content', 'convert_external_links_to_base64');

再在网站根目录新建一个php文件命名为redirect.php ,并且添加如下代码

 

<?php if (isset($_GET['url'])) { $link = base64_decode($_GET['url']); } ?> <!doctype html> <html lang="zh"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <link rel="stylesheet" type="text/css" href="static/css/style.css"> <link rel="icon" href="https://www.xrbk.cn/favicon.png" type="image/x-icon"/><!--favicon图片地址--> <title>新锐博客 - 安全中心</title><!--修改文字--> </head> <body> <div class="go-wild-box"> <div class="go-wild-container"> <a href="https://www.xrbk.cn/"> <img alt="新锐博客" src="/wp-content/uploads/f4a9f982d722de858fd133baf4ff14b7.webp" class="logo-img" /><!--修改Logo地址--> </a> <div class="tips-title">您即将离开新锐博客,跳转到第三方链接</div><!--修改文字--> <div class="address"><?php echo htmlspecialchars($link); ?></div> <div class="tips-subtitle">请注意您的账号和财产安全</div> <div class="btn-groups"> <button onclick="try { window.close(); } catch(e) { alert('请手动关闭此页面'); }" type="button" class="ant-btn ant-btn-default">取消访问</button> <a href="<?php echo htmlspecialchars($link); ?>" rel="nofollow"> <button type="button" class="ant-btn ant-btn-primary">继续访问</button> </a> </div> </div> </div> </body> </html> <style> body { margin: 0; font-family: 'PingFangSC', sans-serif; background-color: #EFF4FA; } .go-wild-box { display: flex; justify-content: center; align-items: center; height: 100vh; } .go-wild-container { width: 770px; height: 330px; max-width: 90%; padding: 90px 15px; background-color: #fff; border-radius: 12px; box-shadow: 0 4px 12px rgba(0, 0, 0, 0.1); text-align: center; } .logo-img { width: 120px; height: auto; } .tips-title { margin: 20px 0; font-size: 22px; color: #2a3c59; font-weight: 500; } .address { margin-bottom: 20px; padding: 15px; background-color: #EFF4FA; border-radius: 8px; color: #2a3c59; white-space: nowrap; overflow: hidden; text-overflow: ellipsis; width: 80%; max-width: 600px; margin: 0 auto; } .tips-subtitle { font-size: 14px; color: #2a3c59; margin-bottom: 30px;margin-top: 20px; } .btn-groups { display: flex; justify-content: center; gap: 10px; margin-top: 60px; } .ant-btn { width: 152px; height: 44px; line-height: 44px; border-radius: 20px; border: none; cursor: pointer; font-size: 14px; transition: all 0.3s ease; } .ant-btn-primary { background: linear-gradient(152deg, #07C160 0%, #07c183 100%); color: #fff; } .ant-btn-default { background-color: #fff; color: #2a3c59; border: 1px solid #ccc; } .ant-btn-default:hover { background-color: #fff; border-color: #07C160; color: #07C160; } </style>

结语
这样访问文章和页面中的外部链接就可以跳转到中间页了
