Codeigniter Rss,网站地图,路由配置
_ _,今天在成果不错,完成了网站的三个功能,RSS订阅,自动写网站地图,与路由的配置,好了,现在一 一记录下来.
一、路由配置
在未设定路由时,路径是这样的
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:
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
/*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/$1";
二、RSS
-
在libraries目录下创建Rss.php文件,主要负责生成RSS格式的数据内容
<?php if(!defined('BASEPATH')) exit('No direct script access allowed');
/**
* Rss
*/
class Rss{
public function write_rss($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>"
."<description>".$in_datas["page_description"]."</description>"
."<language>zh-cn</language> "
."<sy:updateFrequency>1</sy:updateFrequency>"
."<sy:updatePeriod>hourly</sy:updatePeriod> "
."<dc:rights>Copyright (C) Xiuxiandou.com. All rights reserved.</dc:rights>"
."<generator>http://www.xiuxiandou.com</generator>";
if(!empty($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
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()));
$blog=$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);
$this->_comm($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'] = '[email protected]';
$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
http://www.xiuxiandou.com/feed生成结果如下
<rss 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/" version="2.0"> <channel> <title>休闲豆 RSS</title> <atom:link href="http://www.xiuxiandou.com/free" rel="self" type="application/rss+xml"/> <link>http://www.xiuxiandou.com/free</link> <description>休闲豆,IT资讯,IT电子书,游戏种子,电影BT RSS</description> <language>zh-cn</language> <sy:updateFrequency>1</sy:updateFrequency> <sy:updatePeriod>hourly</sy:updatePeriod> <dc:rights>Copyright (C) Xiuxiandou.com.

三、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
在网站上找到一个封装sitemaps的类,地址为:http://signalkraft.com/google-sitemaps-for-codeigniter
1、加载libraries目录下的sitemaps.php类,内容如下
<?php if (!defined('BASEPATH')) exit('No direct script access allowed');
/**
* A class for generating XML sitemaps
*
* @author Philipp Dörner <[email protected]>
* @version 0.7

function Sitemaps()
{
$CI =& get_instance();
$CI->config->load('sitemaps');
}
/**
* Adds a new item to the urlset
*
* @param array $new_item
* @access public
*/
function add_item($new_item)
{
$this->items[] = $new_item;
}
/**
* Adds an array of items to the urlset
*
* @param array $new_items array of items
* @access public
*/
function add_item_array($new_items)
{
$this->items = array_merge($this->items, $new_items);
}

*/
function build($file_name = null, $gzip = NULL)
{
$CI =& get_instance();
$map = $CI->config->item('sitemaps_header') . "\n";
foreach($this->items as $item)
{
$item['loc'] = htmlentities($item['loc'], ENT_QUOTES);
$map .= "\t<url>\n\t\t<loc>" . $item['loc'] . "</loc>\n";
$attributes = array("lastmod", "changefreq", "priority");
foreach($attributes AS $attr)
{
if(isset($item[$attr]))
{
$map .= "\t\t<$attr>" . $item[$attr] . "</$attr>\n";
}
}
$map .= "\t</url>\n\n";
}
unset($this->items);
$map .= $CI->config->item('sitemaps_footer');
if( ! is_null($file_name))
{
$fh = fopen($file_name, 'a');//w
fwrite($fh, $map);
fclose($fh);
if($CI->config->item('sitemaps_filesize_error') && filesize($file_name) > 1024 * 1024 * 30)
{
show_error('Your sitemap is bigger than 10MB, most search engines will not accept it.');
}
if($gzip OR (is_null($gzip) && $CI->config->item('sitemaps_gzip')))
{
$gzdata = gzencode($map, 9);
$file_gzip = str_replace("{file_name}", $file_name, $CI->config->item('sitemaps_gzip_path'));
$fp = fopen($file_gzip, "a");//w
fwrite($fp, $gzdata);
fclose($fp);
// Delete the uncompressed sitemap
unlink($file_name);
return $file_gzip;
}
return $file_name;
}
else
{
return $map;
}
}
/**
* Generate a sitemap index file pointing to other sitemaps you previously built
*
* @param array $urls array of urls, each being an array with at least a loc index

*/
function build_index($urls, $file_name = null, $gzip = null)
{
$CI =& get_instance();
$index = $CI->config->item('sitemaps_index_header') . "\n";

$index .= "\t<sitemap>\n\t\t<loc>" . $url['loc'] . "</loc>\n";
if(isset($url['lastmod']))
{

}
$index .= "\t</sitemap>\n\n";
}
$index .= $CI->config->item('sitemaps_index_footer');
if( ! is_null($file_name))
{
$fh = fopen($file_name, 'w');
fwrite($fh, $index);
fclose($fh);
if($CI->config->item('sitemaps_filesize_error') && filesize($file_name) > 1024 * 1024 * 10)
{
show_error('Your sitemap index is bigger than 10MB, most search engines will not accept it.');
}
if($gzip OR (is_null($gzip) && $CI->config->item('sitemaps_index_gzip')))

fwrite($fp, $gzdata);
fclose($fp);
// Delete the uncompressed sitemap index
unlink($file_name);
return $file_gzip;
}
return $file_name;
}
else
{
return $index;
}
}
/**

*/
function ping($url_xml, $search_engines = NULL)
{
$CI =& get_instance();
if(is_null($search_engines))
{
$search_engines = $CI->config->item('sitemaps_search_engines');
}
$statuses = array();
foreach($search_engines AS $engine)
{
$status = 0;
if($fp = @fsockopen($engine['host'], 80))
{
$engine['url'] = empty($engine['url']) ? "/ping?sitemap=" : $engine['url'];
$req = 'GET ' . $engine['url'] .
urlencode($url_xml) . " HTTP/1.1\r\n" .
"Host: " . $engine['host'] . "\r\n" .
$CI->config->item('sitemaps_user_agent') .
"Connection: Close\r\n\r\n";
fwrite($fp, $req);
while( ! feof($fp))
{
if(@preg_match('~^HTTP/\d\.\d (\d+)~i', fgets($fp, 128), $m))
{
$status = intval($m[1]);
break;
}
}
fclose($fp);
}
$statuses[] = array("host" => $engine['host'], "status" => $status, "request" => $req);
}
if($CI->config->item('sitemaps_log_http_responses') OR $CI->config->item('sitemaps_debug'))
{
foreach($statuses AS $reponse)
{
$message = "Sitemaps: " . $reponse['host'] . " responded with HTTP status " . $reponse['status'];
if($CI->config->item('sitemaps_log_http_responses'))
{
$level = $reponse['status'] == 200 ? 'debug' : 'error';
log_message($level, $message);
}
if($CI->config->item('sitemaps_debug'))
{
echo "<p>" . $message . " after request:</p>\n<pre>" . $reponse['request'] . "</pre>\n\n";
}
}
}
return $statuses;
}
}
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);
$file_name="sitemap.xml";
if(!empty($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;
}
}
