请问为何文件传不到阿里云上，这段代码哪里不对

    function uploadopenossserver($filer,$ossid=1,$type=0){
        global $empire,$dbtbpre,$public_r,$ftp_r,$oss_r,$incftp;            
            $pr=getossserverinfo($ossid);       
            @include(ECMS_PATH."e/extend/aliyun/oss/sdk.class.php");
            if(!$pr[hostname]){
                    if($pr[osstype]=='1') { $pr[hostname]='oss-cn-hangzhou.aliyuncs.com'; }
                    elseif($pr[osstype]=='2'){ $pr[hostname]='oss-cn-hangzhou-internal.aliyuncs.com'; }
                    elseif($pr[osstype]=='3'){ $pr[hostname]='oss-cn-qingdao.aliyuncs.com'; }
                    elseif($pr[osstype]=='4'){ $pr[hostname]='oss-cn-qingdao-internal.aliyuncs.com'; }
                    elseif($pr[osstype]=='5'){ $pr[hostname]='oss-cn-beijing.aliyuncs.com'; }
                    elseif($pr[osstype]=='6'){ $pr[hostname]='oss-cn-beijing-internal.aliyuncs.com'; }
                    elseif($pr[osstype]=='7'){ $pr[hostname]='oss-cn-hongkong.aliyuncs.com'; }
                    elseif($pr[osstype]=='8'){ $pr[hostname]='oss-cn-hongkong-internal.aliyuncs.com'; }
                    elseif($pr[osstype]=='9'){ $pr[hostname]='oss-cn-shenzhen.aliyuncs.com'; }
                    else{ $pr[hostname]='oss-cn-hangzhou-internal.aliyuncs.com'; } 
            }
            else{
                printerror2("OSS节点选择错误，无法同步");
            }   

            $oss=new ALIOSS($pr[Access_Key_ID],$pr[Access_Key_Secret],$pr[hostname]);
            $oss->set_debug_mode(FALSE);

        foreach ($filer as $file){
            $object=str_replace(ECMS_PATH,'',$file);
            //$truefile=RTruePathOpen($pr[bucket],$filenopath);
            $oss->upload_file_by_file($pr[bucket],$object,$file);
            //上传文件
            print_r($oss);
        }
        //退出OSS
        $oss=NULL;
        return true;                

}
