开玩笑,就算你要跑好歹你也弄成命令行的模式跑呀....
------解决方案--------------------应该是xiami.com服务器有限制,禁止采集吧
1,每个url请求只采10-20打,然后做个跳转在继续采集,这样也可以防止页面超时,如果你在虚机上运行,长时间点用cpu,进程可能会被kill.
2,每次url请求header中的user-agent,cookies,最好都能改一下。
3,如果还不行,用火车头试试吧!
4,如果火车也不行,那就放弃这个站吧!
------解决方案--------------------把foreach拆分成循环执行同一页面。
第一次浏览器或者cronrab定时执行 http://localhost/caiji.php?num=1 每次完成后,$_GET['num']+1;curl 重复l执行同一脚本,当$_GET['num']==1000后,退出,不再执行curl。
if($_GET['num']){<br />$url = 'http://www.xiami.com/song/'.$_GET['num'];<br />//你的代码<br />$_GET['num'])++;<br />}<br />if($_GET['num']<1001){<br /> $ch = curl_init();<br /> curl_setopt($ch, CURLOPT_URL,"http://localhost/caiji.php?num=".$_GET['num']));<br /> curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);<br /> curl_setopt($ch, CURLOPT_CONNECTTIMEOUT ,2); <br /> curl_setopt($ch, CURLOPT_TIMEOUT ,2);<br /> curl_exec($ch);<br /> curl_close($ch);<br />}else{<br /> exit;<br />}<br />
