[APP接口] -- PHP开发APP接口（二）

原文地址:  http://www.cnblogs.com/xp796/p/5347375.html

这里将会调用前面博客的数据库连接单例、文件缓存类和开发APP接口（一）

cacheData('index_cron_cahce');  
if($data) {  
    return Response::show(200, '首页数据获取成功', $data);  
}else{  
    return Response::show(400, '首页数据获取失败', $data);  
}  
exit;  
require_once('./db.php');  
require_once('./file.php');  
$page = isset($_GET['page']) ? $_GET['page'] : 1;  
$pageSize = isset($_GET['pagesize']) ? $_GET['pagesize'] : 6;  
if(!is_numeric($page) || !is_numeric($pageSize)) {  
    return Response::show(401, '数据不合法');  
}  
  
$offset = ($page - 1) * $pageSize;  
  
$sql = "select * from video where status = 1 order by orderby desc limit ". $offset ." , ".$pageSize;  
$cache = new File();  
$videos = array();  
if(!$videos = $cache->cacheData('index_mk_cache' . $page .'-' . $pageSize)) {  
    echo 1;exit;  
    try {  
        $connect = Db::getInstance()->connect();  
    } catch(Exception $e) {  
        // $e->getMessage();  
        return Response::show(403, '数据库链接失败');  
    }  
    $result = mysql_query($sql, $connect);   
      
    while($video = mysql_fetch_assoc($result)) {  
        $videos[] = $video;  
    }  
  
    if($videos) {  
        $cache->cacheData('index_mk_cache' . $page .'-' . $pageSize, $videos, 1200);  
    }  
}  
  
if($videos) {  
    return Response::show(200, '首页数据获取成功', $videos);  
} else {  
    return Response::show(400, '首页数据获取失败', $videos);  
}
