主要实现了在后台查看日志列表及打包下载功能。
由于用到了PHP压缩功能，特此记录下。
压缩下载类：
Hzip.php

逻辑部分无非就是打开某个目录，然后列出来：
/**
* 日志管理
*/
public function LogsList(){
//默认路径
$default_dir = APP_PATH . "Logs/";
//获取路径
if(isset($_GET['path'])){
$dirpath = $_GET['path'];
}else{
$dirpath = $default_dir;
}
//路径安全检查
if(stripos($dirpath, 'Logs') === false){
$dirpath = $default_dir;
}
//规范化路径
$dirpath = realpath($dirpath);
//操作
$op = empty($_GET['op']) ? 'list' : $_GET['op'];
switch ($op){
case 'list':
$this->LogsListList($dirpath);
break;
case 'download':
\Yjc\Hzip::download($dirpath);
break;
}
}
private function LogsListList($dirpath){
//打开路径
$d = dir($dirpath);
$data = array();
$data['path'] = $d -> path;
// $data['log_path'] = getDomain() . "/Logs/http/$date";
while ( false !== ( $entry = $d -> read ())) {
// $entryname = realpath($d -> path .'/'. $entry);
$entryname = $d -> path .'/'. $entry;
// $filesize = \Yjc\Hzip::getDirSize($entryname);
$filesize = filesize($entryname);
$files = array(
'path' => $d->path,
'name' => $entry,
'entry' => $entryname,
'size' => \Yjc\Hzip::convertSize($filesize),//大小
'mtime' => filemtime ($entryname),
'type' => is_dir($entryname) ? 'dir' : 'file',
'can_down' => in_array($entry, array('.', '..')) ? 0 : 1,
);
$filenames[] = $entry;
$data['entrys'][] = $files;
}
//排序
array_multisort($filenames,SORT_ASC,SORT_STRING, $data['entrys']);
$d -> close ();
// dump($data);
$this->assign('data', $data);
$this->display(':http_logs_list');
}
前端把$data展示出来就行啦：
<table class="table table-striped table-bordered table-hover dataTable no-footer" role="grid" aria-describedby="sample_1_info">
<thead>
<tr role="row">
<th width="13%">文件名</th>
<th width="7%">大小</th>
<th width="7%">类型</th>
<th width="13%">更新时间</th>
<th width="6%">操作</th>
</tr>
</thead>
<tbody>
<volist name="data.entrys" id="vo">
<tr class="gradeX odd" role="row">
<td>
<eq name="vo.type" value="dir">
<a href="{:U('Logstats/LogsList')}?path={$vo.entry}">{$vo.name} <i class="fa"></i></a>
<else/>
{$vo.name}
</eq>
</td>
<td>{$vo.size}</td>
<td>{$vo.type}</td>
<td>{$vo.mtime|date='Y-m-d H:i:s' , ###}</td>
<td>
<eq name="vo.can_down" value="1">
<a href="{:U('Logstats/LogsList')}?op=download&path={$vo.entry}" target="_blank" class="btn btn-xs green">下载 <i class="fa"></i></a>
<else/>
</eq>
</td>
</tr>
</volist>
</tbody>
