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. 

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. 

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. 

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;

    if(empty($cfg_ddimg_width))    $cfg_ddimg_width = 320;

    $rsimg = '';

    $img_array = array_unique($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();

    }
