背景介绍:
火车头采集器对接织梦cms图片集发布时, 对于多张(超过30张)大图片时, 经常会出现图集发布超时的情况.
问题分析:
因为php对于资源的处理有默认的超时时间30秒, 而我尝试了好多方法, 都无法规避php运行30秒超时的这个问题. 所以想了个折中方案.
折中方案:
在采集网上图片时, 判断当前采集了如果已经到了28秒, 那么就不再采集下面的其他图片.
修改php代码:
打开文件dede/inc/inc_archives_functions.php
关注下列代码中begin_time和now_time判断部分.
function GetCurContentAlbum($body, $rfurl, &$firstdd) { global $dsql,$cfg_multi_site,$cfg_basehost,$cfg_ddimg_width; global $cfg_basedir,$pagestyle,$cuserLogin,$cfg_addon_savetype; $begin_time = time(); require_once(DEDEINC.'/dedecollection.func.php'); if(empty($cfg_ddimg_width)) $cfg_ddimg_width = 320; $rsimg = ''; $cfg_uploaddir = $GLOBALS['cfg_image_dir']; $cfg_basedir = $GLOBALS['cfg_basedir']; $basehost = 'http://'.$_SERVER['HTTP_HOST']; //$img_array = array(); //echo "<br />body: ".$body; preg_match_all("/(src)=["|'| ]{0,}(http://([^>]*).(gif|jpg|png))/isU",$body,$img_array); $img_array = array_unique($img_array); //echo "<br />"; //print_r($img_array); $imgUrl = $cfg_uploaddir.'/'.MyDate($cfg_addon_savetype, time()); $imgPath = $cfg_basedir.$imgUrl; if(!is_dir($imgPath.'/')) { MkdirAll($imgPath,$GLOBALS['cfg_dir_purview']); CloseFtp(); } $milliSecond = 'co'.dd2char( MyDate('ymdHis',time())) ; foreach($img_array as $key=>$value) { for ($i = 0; $i < count($value); $i++) { $now_time = time(); if ($now_time - $begin_time >= 28) { //已经执行了28秒, 很快就超时了, 不再获取其他外部资源, 避免超时 return $rsimg; } $value1 = $value[$i]; $value1 = trim($value1); $value1 = str_replace("src='", "", $value1); $value1 = str_replace("src=", "", $value1); $value1 = str_replace("src="", "", $value1); echo "<br />download img from web: ".$value1; if(preg_match("#".$basehost."#i", $value1) || !preg_match("#^http://#i", $value1) || ($cfg_basehost != $basehost && preg_match("#".$cfg_basehost."#i", $value1))) { //echo "<br />continue;"; continue; } $itype = substr($value1, -4, 4); if( !preg_match("#.(gif|jpg|png)#", $itype) ) $itype = ".jpg"; $rndFileName = $imgPath.'/'.$milliSecond.'-'.$key.'-'.$i.$itype; $iurl = $imgUrl.'/'.$milliSecond.'-'.$key.'-'.$i.$itype; //echo "<br /> iurl:".$iurl; //下载并保存文件 $rs = DownImageKeep($value1, $rfurl, $rndFileName, '', 0, 30); if($rs) { $info = ''; $imginfos = GetImageSize($rndFileName, $info); $fsize = filesize($rndFileName); $filename = $milliSecond.'-'.$key.$itype; //保存图片附件信息 $inquery = "INSERT INTO `#@__uploads`(arcid,title,url,mediatype,width,height,playtime,filesize,uptime,mid) VALUES ('0','$filename','$iurl','1','{$imginfos[0]}','$imginfos[1]','0','$fsize','".time()."','".$cuserLogin->getUserID()."'); "; $dsql->ExecuteNoneQuery($inquery); $fid = $dsql->GetLastID(); AddMyAddon($fid, $iurl); if($pagestyle > 2) { $litpicname = GetImageMapDD($iurl, $cfg_ddimg_width); } else { $litpicname = $iurl; } if(empty($firstdd) && !empty($litpicname)) { $firstdd = $litpicname; if(!file_exists($cfg_basedir.$firstdd)) { $firstdd = $iurl; } } @WaterImg($rndFileName, 'down'); $rsimg .= "{dede:img ddimg='$litpicname' text='' width='".$imginfos[0]."' height='".$imginfos[1]."'} $iurl {/dede:img} "; } } } return $rsimg; }
