DedeCMS系统TAG标签伪静态设置方法

　DedeCMS的系统TAGS确实是一个非常好的功能，通过关键词链接可以快速寻找到相关内容，不过很多人希望能够将TAGS静态化这样更加利于SEO，CIT.CN也是对此进行了优化和调整，只不过cit小虫觉得这种更新内容比较频繁的列表最好采用伪静态的方式，这里就分享下技巧。

　　1.修改前台显示链接

　　我们这里达到的效果就是使原来/tags.php?keywors更改为/tags/keywords.html。

　　这里主要修改下调用的标签，在/include/taglib/tag.lib.php中，在87行找到

$row['link'] = $cfg_cmsurl."/tags?".urlencode($row['keyword']);

将其改为：

$row['link'] = $cfg_cmsurl."/tags/".urlencode($row['keyword']).".html";

2.修改分页代码

　　我们需要修改include/arc.taglist.class.php，将分页函数替换为：

/**     *  获取动态的分页列表
     *
     * @access    public
     * @param     int  $list_len  列表宽度
     * @param     string  $listitem  列表样式
     * @return    string
     */
    function GetPageListDM($list_len,$listitem="info,index,end,pre,next,pageno")
    {
        $prepage="";
        $nextpage="";
        $prepagenum = $this->PageNo - 1;
        $nextpagenum = $this->PageNo + 1;
        if($list_len == "" || preg_match("/[^0-9]/", $list_len))
        {
            $list_len = 3;
        }
        $totalpage = $this->TotalPage;
        if($totalpage <= 1 && $this->TotalResult > 0)
        {
            return "<span class="pageinfo">共1页/".$this->TotalResult."条</span>";
        }
        if($this->TotalResult == 0)
        {
            return "<span class="pageinfo">共0页/".$this->TotalResult."条</span>";
        }
        $maininfo = "<span class="pageinfo">共{$totalpage}页/".$this->TotalResult."条</span>rn";
        $purl = $this->GetCurUrl();
        $basename = basename($purl);
        $tmpname = explode('.', $basename);
         
        $purl = str_replace($basename, '', $purl).urlencode($this->Tag);
        //var_dump($purl);exit;
        //$purl .= "?/".urlencode($this->Tag);
  
        //获得上一页和下一页的链接
        if($this->PageNo != 1)
        {
            $prepage.="<li><a href='".$purl."-$prepagenum'.html>上一页</a></li>rn";
            $indexpage="<li><a href='".$purl."-1.html'>首页</a></li>rn";
        }
        else
        {
            $indexpage="<li><a>首页</a></li>rn";
        }
        if($this->PageNo!=$totalpage && $totalpage>1)
        {
            $nextpage.="<li><a href='".$purl."-$nextpagenum.html'>下一页</a></li>rn";
            $endpage="<li><a href='".$purl."-$totalpage.html'>末页</a></li>rn";
        }
        else
        {
            $endpage="<li><a>末页</a></li>rn";
        }
  
        //获得数字链接
        $listdd="";
        $total_list = $list_len * 2 + 1;
        if($this->PageNo >= $total_list)
        {
            $j = $this->PageNo - $list_len;
            $total_list = $this->PageNo + $list_len;
            if($total_list > $totalpage)
            {
                $total_list = $totalpage;
            }
        }
        else
        {
            $j=1;
            if($total_list > $totalpage)
            {
                $total_list = $totalpage;
            }
        }
        for($j; $j<=$total_list; $j++)
        {
            if($j == $this->PageNo)
            {
                $listdd.= "<li class="thisclass"><a>$j</a></li>rn";
            }
            else
            {
                $listdd.="<li><a href='".$purl."-$j.html'>".$j."</a></li>rn";
            }
        }
        $plist  =  '';
        if(preg_match('/info/i', $listitem))
        {
            $plist .= $maininfo.' ';
        }
        if(preg_match('/index/i', $listitem))
        {
            $plist .= $indexpage.' ';
        }
        if(preg_match('/pre/i', $listitem))
        {
            $plist .= $prepage.' ';
        }
        if(preg_match('/pageno/i', $listitem))
        {
            $plist .= $listdd.' ';
        }
        if(preg_match('/next/i', $listitem))
        {
            $plist .= $nextpage.' ';
        }
        if(preg_match('/end/i', $listitem))
        {
            $plist .= $endpage.' ';
        }
        return $plist;
    }

3.设置伪静态规则

　　我们这里以iis7为例子，设置以下规则：

<?xml version="1.0" encoding="UTF-8"?>
 
<configuration>
 
    <system.webServer>
 
        <rewrite>
 
            <rules>
 
                <rule name="weather1" stopProcessing="true">
 
                    <match url="tags/([^-]+).html$" ignoreCase="true" />
 
                    <conditions logicalGrouping="MatchAll">
 
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
 
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
 
                    </conditions>
 
                    <action type="Rewrite" url="/tags.php?/{R:1}" appendQueryString="false" />
 
                </rule>
 
                <rule name="weather2" stopProcessing="true">
 
                    <match url="tags/([^-]+)-([0-9]+).html$" ignoreCase="true" />
 
                    <conditions logicalGrouping="MatchAll">
 
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
 
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
 
                    </conditions>
 
                    <action type="Rewrite" url="/tags.php?/{R:1}/{R:2}" appendQueryString="false" />
 
                </rule>
 
            </rules>
 
        </rewrite>
 
    </system.webServer>
 
</configuration>

可以直接保存为web.config放在站点根目录。

　　4.重新生成html页面

　　这个操作就不用说了，全部重新生成下，至此全部修改完毕。

　　5.预览查看显示结果
