php 基于阿里云sso实现简单下载站点

基于阿里云云存储的一个简单下载页，支持目录，操作方便

#获取object列表
function list_object($obj,$dir='',$bucket=BUCKET){
    $options = array(
        'delimiter' => '/',
        'prefix' => $dir,
        'max-keys' => 100,
    );

    $response = $obj->list_object($bucket,$options);
    return $response->body;
}

#处理返回内容 
// 处理目录
if(isset($list_object['CommonPrefixes'])){
    foreach($list_object['CommonPrefixes'] as $s){
        $prefix = is_array($s)?$s['Prefix']:$s;
        $file['path'] = "http://".$_SERVER ['HTTP_HOST'].$_SERVER['PHP_SELF'].'?dir='.$prefix;
        $file['Prefix'] =  $prefix;
        $dir_arr[] = $file;
    }
}
// 处理文件
if(isset($list_object['Contents'])){
    foreach($list_object['Contents'] as $k=>$s){
        if ($k!="0"){
            $file['path'] = (get_sign_url($oss_sdk_service,$s['Key']));
            $file['Key'] =  str_replace($list_object['Contents']['0']['Key'],"",$s['Key']);
            $file['Size'] = formatter_size($s['Size']);
            $file_arr[] = $file;
        }
    }
}
