Codeigniter Rss,网站地图,路由配置
发布时间：2015-05-27 19:29:17作者：知识屋
一、路由配置
在未设定路由时,路径是这样的
[php]
http://www.xiuxiandou.com/content/it/13533/硅谷传奇投资人讲述初创企业家易犯的4大错误
content =>controller,it=>method,13533=>id,硅谷传奇投资人讲述初创企业家易犯的4大错误=>title
http://www.xiuxiandou.com/content/it/13533/硅谷传奇投资人讲述初创企业家易犯的4大错误
content =>controller,it=>method,13533=>id,硅谷传奇投资人讲述初创企业家易犯的4大错误=>title
设置路由后,访问路径为:
[php]
http://www.xiuxiandou.com/content-it-13533-硅谷传奇投资人讲述初创企业家易犯的4大错误
http://www.xiuxiandou.com/content-it-13533-硅谷传奇投资人讲述初创企业家易犯的4大错误
其它的类似,路径配置为
[php]
/*sitemap使用*/
$route['content-(:any)-(:num)'] = "content/$1/$2";
/*前台页面显示路由*/
$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";
/*RSS订阅路由*/
$route['feed-rss-(:any)'] = "feed/rss/$1";
/*博客路由*/
$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";
$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";
/**留言**/
$route['me'] = "indexs/me";
/**模板**/
$route["template"]="indexs/template";
/**今日更新**/
$route["indexs-(:any)"]="indexs/$1";
/*sitemap使用*/
$route['content-(:any)-(:num)'] = "content/$1/$2";
/*前台页面显示路由*/
$route['content-(:any)-(:num)-(:any)'] = "content/$1/$2/$3";
/*RSS订阅路由*/
$route['feed-rss-(:any)'] = "feed/rss/$1";
/*博客路由*/
$route['blog-(:num)-(:any)'] = "blog/blogview/$1/$2";
$route['blog-blogtypes-(:any)']="blog/blogtypes/$1";
/**留言**/
$route['me'] = "indexs/me";
/**模板**/
$route["template"]="indexs/template";
/**今日更新**/
$route["indexs-(:any)"]="indexs/$1";
二、RSS
在libraries目录下创建Rss.php文件,主要负责生成RSS格式的数据内容
[php]
<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Rss
*/
class Rss{
public function write_rss($in_datas){
$CI=& get_instance();
$CI->load->helper('xml');
$CI->load->helper('text');
$xml_str="<?xml version='1.0' encoding='UTF-8'?>"
."<rss version='2.0' xmlns:content='http://purl.org/rss/1.0/modules/content/' xmlns:wfw='http://wellformedweb.org/CommentAPI/' xmlns:dc='http://purl.org/dc/elements/1.1/' xmlns:atom='http://www.w3.org/2005/Atom' xmlns:sy='http://purl.org/rss/1.0/modules/syndication/' xmlns:slash='http://purl.org/rss/1.0/modules/slash/' >";
if(!emptyempty($in_datas)){
$xml_str.="<channel>"
."<title>".$in_datas["feed_name"]."</title>"
."<atom:link href='".$in_datas["feed_url"]."' rel='self' type='application/rss+xml' />"
."<link>".$in_datas["feed_url"]."</link>"
."<description>".$in_datas["page_description"]."</description>"
."<language>zh-cn</language> "
."<sy:updateFrequency>1</sy:updateFrequency>"
."<sy:updatePeriod>hourly</sy:updatePeriod> "
."<dc:rights>Copyright (C) Xiuxiandou.com. All rights reserved.</dc:rights>"
."<generator>http://www.xiuxiandou.com</generator>";
if(!emptyempty($in_datas["xml_datas"])){
foreach($in_datas["xml_datas"] as $k => $v){
foreach($v as $xml){
$xml_str.=" <item>"
."<title><![CDATA[ ".xml_convert($xml->subject)."]]> </title>"
."<link>".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject)))."</link>"
."<guid>".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject)))."</guid>"
."<description><![CDATA[".character_limiter(xml_convert($xml->message, 600))."]]></description>"
."<pubdate>".date('Y-m-d h:i:s',$xml->dateline)."</pubdate> "
."<author>$xml->url</author>"
."</item>";
}
}
}
$xml_str.="</channel>";
}
$xml_str.="</rss>";
return $xml_str;
}
}
<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Rss
*/
class Rss{
public function write_rss($in_datas){
$CI=& get_instance();
$CI->load->helper('xml');
$CI->load->helper('text');
$xml_str="<?xml version='1.0' encoding='UTF-8'?>"
."<rss version='2.0' xmlns:content='http://purl.org/rss/1.0/modules/content/' xmlns:wfw='http://wellformedweb.org/CommentAPI/' xmlns:dc='http://purl.org/dc/elements/1.1/' xmlns:atom='http://www.w3.org/2005/Atom' xmlns:sy='http://purl.org/rss/1.0/modules/syndication/' xmlns:slash='http://purl.org/rss/1.0/modules/slash/' >";
if(!empty($in_datas)){
$xml_str.="<channel>"
."<title>".$in_datas["feed_name"]."</title>"
."<atom:link href='".$in_datas["feed_url"]."' rel='self' type='application/rss+xml' />"
."<link>".$in_datas["feed_url"]."</link>"

."<generator>http://www.xiuxiandou.com</generator>";
if(!empty($in_datas["xml_datas"])){
foreach($in_datas["xml_datas"] as $k => $v){
foreach($v as $xml){
$xml_str.=" <item>"
."<title><![CDATA[ ".xml_convert($xml->subject)."]]> </title>"
."<link>".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject)))."</link>"
."<guid>".site_url("content-$k-$xml->id-".xml_convert($CI->mytool->get_title($xml->subject)))."</guid>"
."<description><![CDATA[".character_limiter(xml_convert($xml->message, 600))."]]></description>"
."<pubdate>".date('Y-m-d h:i:s',$xml->dateline)."</pubdate> "
."<author>$xml->url</author>"
."</item>";
}
}
}
$xml_str.="</channel>";
}
$xml_str.="</rss>";
return $xml_str;
}
}
2、RSS控制类
[php]
<?php
if(!defined('BASEPATH')) exit('No direct script access allowed');
/**
* 2013-2-25:RSS订阅
*/
class Feed extends CI_Controller{
public function index(){
$it=$this->mcom_model->query_Bywhere(mymsg::BT_ITINFO,array("riqi"=>$this->mytool->get_ymd()));
$game=$this->mcom_model->query_Bywhere(mymsg::BT_GAME,array("riqi"=>$this->mytool->get_ymd()));

$in_datas["xml_datas"]=array("it"=>$it,"game"=>$game,"blog"=>$blog,"movie"=>$movie,"book"=>$book);
$this->_comm($in_datas);
}
public function rss(){
$this->load->helper('xml');
$this->load->helper('text');
$key= $this->uri->segment(3);
$db_table= $key=="it"?"bt_itinfo":"bt_$key";
$table_exist=$this->mcom_model->table_exists($db_table);
if($table_exist){
$in_datas["xml_datas"]=array($key=>$this->mcom_model->query_Bywhere($db_table,array("riqi"=>$this->mytool->get_ymd())));
$this->_comm($in_datas);
}else{
show_404();
}
}
private function _comm($in_datas){
$in_datas['feed_name'] = "休闲豆 RSS";
$in_datas['feed_url'] = base_url()."free";
$in_datas['page_description'] = '休闲豆,IT资讯,IT电子书,游戏种子,电影BT RSS';
$in_datas['creator_email'] = '1963612630@qq.com';
$in_datas['page_language']="zh-zn";
$out_datas["xml"]=$this->rss->write_rss($in_datas);
header("Content-Type: text/xml");
$this->load->view("rss",$out_datas);
}
}
<?php
if(!defined('BASEPATH')) exit('No direct script access allowed');
/**
* 2013-2-25:RSS订阅
*/
class Feed extends CI_Controller{
public function index(){
$it=$this->mcom_model->query_Bywhere(mymsg::BT_ITINFO,array("riqi"=>$this->mytool->get_ymd()));
$game=$this->mcom_model->query_Bywhere(mymsg::BT_GAME,array("riqi"=>$this->mytool->get_ymd()));

$book=$this->mcom_model->query_Bywhere(mymsg::BT_BOOK,array("riqi"=>$this->mytool->get_ymd()));
$in_datas["xml_datas"]=array("it"=>$it,"game"=>$game,"blog"=>$blog,"movie"=>$movie,"book"=>$book);
$this->_comm($in_datas);
}
public function rss(){
$this->load->helper('xml');
$this->load->helper('text');
$key= $this->uri->segment(3);
$db_table= $key=="it"?"bt_itinfo":"bt_$key";
$table_exist=$this->mcom_model->table_exists($db_table);
if($table_exist){

$this->_comm($in_datas);
}else{
show_404();
}
}
private function _comm($in_datas){
$in_datas['feed_name'] = "休闲豆 RSS";
$in_datas['feed_url'] = base_url()."free";
$in_datas['page_description'] = '休闲豆,IT资讯,IT电子书,游戏种子,电影BT RSS';
$in_datas['creator_email'] = '1963612630@qq.com';
$in_datas['page_language']="zh-zn";
$out_datas["xml"]=$this->rss->write_rss($in_datas);
header("Content-Type: text/xml");
$this->load->view("rss",$out_datas);
}
}
运行
[html]
生成结果如下
[php]
<rss xmlns:c xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:slash="http://purl.org/rss/1.0/modules/slash/" versi

3、网站地图
网站地图主要根据sitemaps.xml协议拼写的XML,协议地址:http://www.sitemaps.org/protocol.html
1、加载libraries目录下的sitemaps.php类,内容如下

2、sitemap.php控制类,注意这里不要与libraries中的sitemaps.php同名,不然会报错的.
<?php
if(!defined('BASEPATH')) exit('No direct script access allowed');
/**
* 2013-2-25:网站地图
*/
class Sitemap extends CI_Controller{
public function index(){
$file_name =$this->write_xml();
redirect(site_url($file_name));
}
public function write_xml(){
$it=$this->mcom_model->query_Bywhere(mymsg::BT_ITINFO,array("riqi"=>$this->mytool->get_ymd()));
$game=$this->mcom_model->query_Bywhere(mymsg::BT_GAME,array("riqi"=>$this->mytool->get_ymd()));
$blog=$this->mcom_model->query_Bywhere(mymsg::BT_BLOG,array("riqi"=>$this->mytool->get_ymd()));
$movie=$this->mcom_model->query_Bywhere(mymsg::BT_MOVIE,array("riqi"=>$this->mytool->get_ymd()));
$book=$this->mcom_model->query_Bywhere(mymsg::BT_BOOK,array("riqi"=>$this->mytool->get_ymd()));
$in_datas["xml_datas"]=array("it"=>$it,"game"=>$game,"blog"=>$blog,"movie"=>$movie,"book"=>$book);
$file_name="sitemap.xml";
if(!emptyempty($in_datas["xml_datas"])){
foreach($in_datas["xml_datas"] as $k => $v){
foreach($v as $xml){
$item = array(
"loc" => site_url("content-$k-$xml->id"),
"lastmod" => date('Y-m-d',$xml->dateline),
"changefreq" => "hourly",
"priority" => "0.8"
);
$this->sitemaps->add_item($item);
}
}
$file_name = $this->sitemaps->build("sitemap.xml");
}
return $file_name;

}
