一个采集得到信息不全的有关问题
求助一个采集得到信息不全的问题
我要采集这个网站
http://www.tvmao.com/drama/MGxYWA==/episode/0
刚开始的时候,得到的信息是全的,
当采集到一定时候的时候,采集得到的信息只有半了,少了一些文字。
(我然后拿到其它地方用IE打开看的时候,发现先加载了一半文字,过一小会,在加载一半的文字)
(用本地浏览器打开,只有一半的文字)
还请问一下,怎么处理一下。才能获取全部信息。
------解决方案--------------------
有可能这个网站作了防采集处理,同一IP如果访问过频,针对此IP就启动防采集了,这也符合你说的刚开始可以完整采集,时间一长就不行的情况。不过这个还好了,有的网站变态到每次1K字节的间隔输出呢
------解决方案--------------------
------解决方案--------------------
防止采集:
1:用户登录才能访问网站内容
2:利用脚本语言做分页(隐藏分页)
3:防盗链办法(只许可通过本站页面连接查看,如:Request.ServerVariables(“HTTP_REFERER“) )
4:全flash、图片或者pdf来浮现网站内容
5:网站随机接纳不同模版
6:接纳动态不规则的html标签
一旦要同时搜索引擎爬虫和采集器,这是很让人无奈的工作,因为搜索引擎第一步就是采集目标网页内容,这跟采集器原理同样,所以很多防止采集的方法同时也阻碍了搜索引擎对网站的收录,无奈,是吧?以上10条建议虽然不能百分之百防采集,可是几种方法一起适用已经拒绝了一大部分采集器了。
