之前发布过一次给BO-BLOG加上干扰码防采集
http://www.im286.com/thread-2264603-1-1.html
有朋友PM我,让给弄个wordpress 的,可能其它朋友也需要,所以就弄个发出来
效果可以看 http://www.osphp.com.cn
打开 wp-includes\post-template.php
先将代码加到 post-template.php 第一行- function RndString($body)
- {
- //最大间隔距离(如果在检测不到p标记的情况下,加入混淆字串的最大间隔距离)
- $maxpos = 1024;
- //font 的字体颜色
- $fontColor = "#FFFFFF";
- //div span p 标记的随机样式
- $st1 = chr(mt_rand(ord('A'),ord('Z'))).chr(mt_rand(ord('a'),ord('z'))).chr(mt_rand(ord('a'),ord('z'))).mt_rand(100,999);
- $st2 = chr(mt_rand(ord('A'),ord('Z'))).chr(mt_rand(ord('a'),ord('z'))).chr(mt_rand(ord('a'),ord('z'))).mt_rand(100,999);
- $st3 = chr(mt_rand(ord('A'),ord('Z'))).chr(mt_rand(ord('a'),ord('z'))).chr(mt_rand(ord('a'),ord('z'))).mt_rand(100,999);
- $st4 = chr(mt_rand(ord('A'),ord('Z'))).chr(mt_rand(ord('a'),ord('z'))).chr(mt_rand(ord('a'),ord('z'))).mt_rand(100,999);
- $rndstyle[1]['value'] = ".{$st1} { display:none; }";
- $rndstyle[1]['name'] = $st1;
- $rndstyle[2]['value'] = ".{$st2} { display:none; }";
- $rndstyle[2]['name'] = $st2;
- $rndstyle[3]['value'] = ".{$st3} { display:none; }";
- $rndstyle[3]['name'] = $st3;
- $rndstyle[4]['value'] = ".{$st4} { display:none; }";
- $rndstyle[4]['name'] = $st4;
- $mdd = mt_rand(1,4);
- //以后内容如果你不懂其含义,请不要改动
- //---------------------------------------------------
- $rndstyleValue = $rndstyle[$mdd]['value'];
- $rndstyleName = $rndstyle[$mdd]['name'];
- $reString = "<style> $rndstyleValue </style>\r\n";
- //附机标记
- $rndem[1] = 'font';
- $rndem[2] = 'div';
- $rndem[3] = 'span';
- $rndem[4] = 'p';
- //读取字符串数据
- $fp = fopen(dirname(__FILE__).'/RndString.php','r');
- $start = 0;
- $totalitem = 0;
- while(!feof($fp)){
- $v = trim(fgets($fp,128));
- if($start==1){
- if(ereg("#end#",$v)) break;
- if($v!=""{ $totalitem++; $rndstring[$totalitem] = ereg_replace("#,","",$v); }
- }
- if(ereg("#start#",$v)){ $start = 1; }
- }
- fclose($fp);
- //处理要防采集的字段
- $bodylen = strlen($body) - 1;
- $prepos = 0;
- for($i=0;$i<=$bodylen;$i++){
- if($i+2 >= $bodylen || $i<50) $reString .= $body[$i];
- else{
- @$ntag = strtolower($body[$i].$body[$i+1].$body[$i+2]);
- if($ntag=='</p' || ($ntag=='<br' && $i-$prepos>$maxpos) ){
- $dd = mt_rand(1,4);
- $emname = $rndem[$dd];
- $dd = mt_rand(1,$totalitem);
- $rnstr = $rndstring[$dd];
- if($emname!='font') $rnstr = " <$emname class='$rndstyleName'>$rnstr</$emname> ";
- else $rnstr = " <font color='$fontColor'>$rnstr</font> ";
- $reString .= $rnstr.$body[$i];
- $prepos = $i;
- }
- else $reString .= $body[$i];
- }
- }
- unset($body);
- return $reString;
- }//函数结束
复制代码 查找 function the_content(
将这段代码-
- function the_content($more_link_text = '(more...)', $stripteaser = 0, $more_file = '') {
- $content = get_the_content($more_link_text, $stripteaser, $more_file);
- $content = apply_filters('the_content', $content);
- $content = str_replace(']]>', ']]>', $content);
- echo $content;
- }
复制代码 改成-
- function the_content($more_link_text = '(more...)', $stripteaser = 0, $more_file = '') {
- $content = get_the_content($more_link_text, $stripteaser, $more_file);
- $content = apply_filters('the_content', $content);
- $content = str_replace(']]>', ']]>', $content);
- $content = RndString($content);
- echo $content;
- }
复制代码 注意,就多了行 $content = RndString($content);
上传附件中的RndString.php 文件到wp-includes/下
