WordPress如何实现伪静态加html后缀?本文给大家分享的是在使用WordPress的过程中,发现其内容页分页的形式非常的不友好,于是就动手进行修改的过程以及详细代码,非常的实用,推荐给大家。希望对大家有所帮助。

问题

当文章有分页的时候,WordPress生成的永久链接是page.html/2的形式,前面一段是文章的$link,后面的数字代表分页$number。那么问题来了,挖掘……不对,从逻辑上讲这到底是个html文件还是一个目录呢?

难看

在.html这个静态文件后面加上一个/和数字简直令人摸不着头脑,这还只是其次,重要的是,我发现搜索引擎根本不收录这样奇怪的链接,这个真是无法接受,我写的东西首尾都很重要,不能因为分个页就被忽视了。

不收录

拿这篇文章来看,搜索文章第一页的内容,谷歌收录了:

搜索文章第二页和第三页的内容,根本没有收录:

解决方案

于是我决定DIY WordPress的链接生成与解析规则。

思路

利用filter wp_link_pages_link 将分页链接/123456重写为page-[123456].html。

利用WordPress或者服务器的RewriteRule将page-[123456].html还原为/123456

添加钩子redirect_canonical,防止WordPress从page-[123456].html到/123456的强行跳转。

生成分页html后缀链接

给WordPress主题加入:


class Rewrite_Inner_Page_Links
{
  var $separator;
  var $post_rule;
 
  function __construct()
  {
    $this->separator = '/page-';
    // (.+?)/([^/]+).html(/[0-9]+)?/?
    $this->post_rule = '(.+?)/([^/]+)(' . $this->separator . '([0-9]+))+.html/?$';
    if (!is_admin() || defined('DOING_AJAX')) :
      add_filter('wp_link_pages_link', array($this, 'inner_page_link_format'), 10, 2); // for inner pages
      add_filter('redirect_canonical', array($this, 'cancel_redirect_for_paged_posts'), 10, 2);
    endif;
    if (is_admin()) :
      add_filter('rewrite_rules_array', array($this, 'pagelink_rewrite_rules'));
    endif;
  }
 
  /**
   * 修改post分页链接的格式
   * @param string $link
   * @param int $number
   * @return string
   */
  function inner_page_link_format($link, $number)
  {
    if ($number > 1)
    {
      if (preg_match(&#39;%<a href=".*\.html/\d*"%&#39;, $link))
      {
        $link = preg_replace("%(\.html)/(\d*)%", $this->separator . "$2$1", $link);
      }
    }
    return $link;
  }
 
  /**
   * 为新的链接格式增加重定向规则,移除原始分页链接的重定向规则,防止重复收录
   *
   * 访问原始链接将返回404
   * @param array $rules
   * @return array
   */
  function pagelink_rewrite_rules($rules)
  {
    $new_rule[$this->post_rule] = &#39;index.php?name=$matches[2]&page=$matches[4]&#39;;
    return $new_rule + $rules;
  }
 
  /**
   * 禁止WordPress将页面分页链接跳转到原来的格式
   * @param string $redirect_url
   * @param string $requested_url
   * @return bool
   */
  function cancel_redirect_for_paged_posts($redirect_url, $requested_url)
  {
    global $wp_query;
    if (is_single() && $wp_query->get(&#39;page&#39;) > 1)
    {
      return false;
    }
    return true;
  }
}
 
new Rewrite_Inner_Page_Links();
Copy after login

这样就得到了将类似http://www.***.com/program/tokyodaigaku.html/2/ 的分页链接转化为形如 http://www.***.com/program/tokyodaigaku/page-2.html 的链接。

注意,我的伪静态规则是/%category%/%postname%.html,如果你的规则不同,请自行修改代码或者伪静态规则。

重写URL规则

如果不重写规则的话,WordPress是不认识这个链接的,它以为有个目录叫tokyodaigaku,里面有篇文章叫page-2.html,结果会给出一个无情的404错误:

利用服务器的重写规则

如果是SAE的话,在config.yaml的第一行加入:

复制代码 代码如下:

- rewrite: if ( !is_dir() && path ~ "(.+?)/([^/]+)(/page-([0-9]+))+.html/?$") goto "index.php?name=$2&page=$4"

如果不是的话,可以利用WordPress自带的rewrite_rules:

登陆后台——设置——固定链接:

什么也不用填,直接保存更改即可。代码会自动在数据库中硬性加入一条规则:

复制代码 代码如下:

"(.+?)/([^/]+)(/page-([0-9]+))+.html/?$" => "index.php?name=$matches[2]&page=$matches[4]"

最终效果

无论是用http://www.***.com/program/tokyodaigaku.html/2/ 还是 http://www.***.com/program/tokyodaigaku/page-2.html,都可以访问第二页。

具体效果放在第二页,顺便测试一下分页后缀效果

好了,基本功能已经实现了,小伙伴们是否明白了呢,如有问题,可以留言探讨哦!
