网站跳转出现404怎么办？肯定是想办法把蜘蛛圈住。下面，一起来看教程。
访问404页面时，跳转到某篇文章，蜘蛛遇到404页面时，随机跳转到某一篇正常的文章，这样就不会浪费任何一个蜘蛛。
教程开始
好的，开整。在根目录新建一个 404.php 文件，代码如下。下面我给两套代码，一套是直接跳转，一套是有预加载动画计时跳转。
代码一：直接跳转
<?php
error_reporting(0);
header('Content-type:text/html;charset=utf-8');
require_once (dirname(__FILE__).'/include/common.inc.php');
$row = $dsql->GetOne("SELECT id,title FROM `#@__archives` WHERE id>=(SELECT FLOOR( MAX(id) * RAND()) FROM `#@__archives`) ORDER BY RAND() LIMIT 0,1 ");
$result = GetOneArchive($row['id']);
if ($cfg_multi_site == 'Y'){
$arcurl = $result['arcurl'];
}else{
$arcurl = $cfg_basehost.$result['arcurl'];
}
$arcurl = str_replace($cfg_basehost.$cfg_basehost,$cfg_basehost, $arcurl);
header('Location: '.$arcurl.'');//直接跳转到文章页
?>这是直接跳转的代码。
代码二：预加载动画
<?php
error_reporting(0);
header('Content-type:text/html;charset=utf-8');
require_once (dirname(__FILE__).'/include/common.inc.php');
$row = $dsql->GetOne("SELECT id,title FROM `#@__archives` WHERE id>=(SELECT FLOOR( MAX(id) * RAND()) FROM `#@__archives`) ORDER BY RAND() LIMIT 0,1 ");
$result = GetOneArchive($row['id']);
if ($cfg_multi_site == 'Y'){
$arcurl = $result['arcurl'];
}else{
$arcurl = $cfg_basehost.$result['arcurl'];
}
$arcurl = str_replace($cfg_basehost.$cfg_basehost,$cfg_basehost, $arcurl);
header('Refresh:3;url='.$arcurl.'');//3秒后跳转到文章页
?>

</html>这是加了预加载动画的代码。
设置404页面
在宝塔面板，网站管理，配置文件中
error_page 404 /404.html;
改为
error_page 404 /404.php;
完成了。当然了，你也可以不用改这个，那就是改个伪静态规则。
Apache伪静态规则
RewriteEngine on RewriteRule ^404.html$ 404.php
如果已经有 RewriteEngine on 的，就不需要 RewriteEngine on 了。
Nginx伪静态规则
rewrite ^/404.html$ /404.php;
完成了。
