_ _, I have achieved good results today. I have completed the three functions of the website, RSS subscription, automatic writing of website map, and routing configuration. Okay, now I will record them one by one.

1. Routing configuration
When no routing is set, the path is like this
[php]
http://www.xiuxiandou.com/content/it/13533/The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
                                                         
content =>controller,it=>method,13533=>id, the legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make=>title
http://www.xiuxiandou.com/content/it/13533/The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
                                                         
content =>controller,it=>method,13533=>id, Silicon Valley legendary investor talks about the 4 major mistakes that start-up entrepreneurs often make=>title
After setting the routing, the access path is:
[php]
http://www.xiuxiandou.com/content-it-13533-The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
http://www.xiuxiandou.com/content-it-13533-The legendary investor in Silicon Valley talks about the 4 major mistakes that start-up entrepreneurs often make
Others are similar, the path configuration is
[php]
/*sitemap usage*/
$route['content-(:any)-(:num)'] = "content/$1/$2";
/*Display routing on the front page*/
$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";
                                                       
/*RSS subscription route*/
$route['feed-rss-(:any)'] = "feed/rss/$1";
/*Blog routing*/
$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";
$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";
                                                       
/**message**/
$route['me'] = "indexs/me";
/**template**/
$route["template"]="indexs/template";
/**Today's update**/
$route["indexs-(:any)"]="indexs/$1";
/*sitemap usage*/
$route['content-(:any)-(:num)'] = "content/$1/$2";
/*Display routing on the front page*/
$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";
                                                       
/*RSS subscription routing*/
$route['feed-rss-(:any)'] = "feed/rss/$1";
/*Blog routing*/
$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";
$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";
                                                       
/**message**/
$route['me'] = "indexs/me";
/**template**/
$route["template"]="indexs/template";
/**Today's update**/
$route["indexs-(:any)"]="indexs/$1";
2. RSS
Create the Rss.php file in the libraries directory, which is mainly responsible for generating data content in RSS format
[php]
/** 
 * Rss 
 */
class Rss{
                                                         
public function write_rss($in_datas){
$CI=& get_instance();
$CI->load->helper('xml');
$CI->load->helper('text');
                                                       
$xml_str=""
                    ."";  
            if(!emptyempty($in_datas)){  
                    $xml_str.=""

                                if(!emptyempty($in_datas["xml_datas"])){  
                                    foreach($in_datas["xml_datas"] as $k => $v){

                                        }  
                                    }  
                                }  
                    $xml_str.="";  
                                 
            }  
            $xml_str.="";  
           return $xml_str;  
    }  
}  
 
/**

3. Site map
The site map is mainly XML spelled according to the sitemaps.xml protocol. The protocol address: http://www.sitemaps.org/protocol.html
