最近有一需求是这样的

原网址
http://aa.test.com/book/book/article/id/99999933475129/book_id/99999917874/channel_id/4838/book_from/0.html
转化后的
http://aa.test.com/book/read/99999933475129/99999917874/4838/0.html

需要保证不能跳转，打开后的网址就是,并且要支持翻页

http://aa.test.com/book/read/99999933475129/99999917874/4838/0.html

实现流程

1、在thinkphp配置文件添加路由，配置规则为 静态地址和动态地址结合

    'DEFAULT_MODULE' => 'Book',
    'URL_REWRITE' => 3,
    'URL_MODEL' => 2,
    // 开启路由
    'URL_ROUTER_ON'   => true, 
    'URL_ROUTE_RULES'=>array(
        'read/:id/:book_id/:channel_id/:book_from' => array("book/article"),
    ),

2、打开http://aa.test.com/book/read/99999933475129/99999917874/4838/0.html看是否能打开，如可以则表示成功

3、由于tp里没有生成路由规则的url, 为了保证生成的url也能支持路由功能，所以我们要在tp核心方式里面添加一小段代码。 在 ThinkPHP\Common\functions.php 里找U方法，在if ($suffix)`上面添加以下代码

if(C('URL_ROUTE_RULES')){
    foreach (C('URL_ROUTE_RULES') as $rule=>$real) {
        $real=$real[0];
        if(strpos($url, $real)!==false){
            $url = str_replace($real, $rule, $url);
            preg_match("/\/(\w+)\.php\/(\w+)/", $url, $match);
            if(isset($match[1]) && isset($match[2]) && $match[1][0]==$match[2][0]){
                $url = preg_replace("/\/(\w+)\.php/", '', $url);
            }elseif(strpos($url, 'index.php')!==false){
                $url = str_replace("/index.php", '', $url);
            }else{
                $url = str_replace(".php", '', $url);
            }
            preg_match_all("/(:\w+)/", $rule, $matches);
            foreach ((array)$matches[1] as $match) {
                $url = str_replace('/'.$match . '/', '/', $url);
                $url = str_replace('/'.substr($match, 1) . '/', '/', $url);
            }
        }   
    }   
}
