为了应对当前HTML格式和js脚本对老人机的不友好,我们需要处理一下某些小说网站,让它回到十几年前的样子,剔除大量CSS和JS,精简HTML标签,这样就能够让老人机快速、友好地看小说了。

目前下面的脚本就能实现了,并且支持缓存,定义处_remoteurl_填写链接,_band_word_用来删除关键词,_band_href_用来删除URL包含该值的链接,_band_ele_用来把某些没有替换掉的元素删除掉,这个设置的存在是由一个正则匹配引起的,一般不要修改。

快速配置:

  1. 基本配置:define处修改remoteurl和其他配置,注意看注释,别乱来。
  2. 搜索配置:找到if ($_GET['search']) :这一行,下面有
$html = c_get('https://search2.booktxt.net/s.php', 'post', 't=1&keyword='.urlencode(_iconv($_GET['search'], 'GBK')));

这样一行,修改c_get的参数即可,第一个参数是url,第二个是方式(post/get),第三个是传输过去的请求字符串,可能要用到转码功能,具体看对面页面的编码,用_iconv(脚本自构的函数)转换。具体写什么需要手动抓取网站信息手动填好。

例子:

//define_remoteurl:  
define('_remoteurl_', 'https://www.biqutxt.com/');
//$_GET['search']后边:
$html = c_get('https://www.biqutxt.com/modules/article/search.php', 'post', 'searchtype=articlename&action=login&searchkey='.urlencode(_iconv($_GET['search'], 'GBK')));

若出现乱码,则可能为转码问题,也可能为原网页的问题,需排查,可以把URL上面的page参数进行urldecode+base64decode即得到源URL。

上代码:

<?php

error_reporting(E_ALL ^ E_WARNING ^ E_NOTICE);
date_default_timezone_set("PRC");

define('_remoteurl_', 'https://m.booktxt.net/'); // 必须用 / 结尾 且 http(s)://开头
define('_band_word_', '字体:|顶点小说移动网(m\.booktxt\.net)|37小说网'); // 用 | 隔开,不能留空
define('_band_href_', 'cnzz\.com|mybook\.php');// 同上
define('_band_ele_', 'link');

$cachee = "cachepage/" . md5($_SERVER["QUERY_STRING"].'haha');

(file_exists("./cachepage/")) ?: mkdir('cachepage');
if (file_exists($cachee)) {
  if (!$_GET['page'])
    $keeptime = 259200; //保存3天
  else
    $keeptime = 31536000; //保存1年
  if (time() - filectime($cachee) >= $keeptime){
    unlink($cachee);
  }else{
    echo file_get_contents($cachee);
    exit;
  }
}
