为何curl或file_get_contents采集url时k数过高则不能获取?

Jun 23, 2016 pm 02:20 PM

之前通过http://bbs.csdn.net/topics/390572750得知了获取方式,但有的链接如下:
http://www.autohome.com.cn/77/options.html
http://www.autohome.com.cn/59/options.html
都可正常获取
但以下链接:
http://www.autohome.com.cn/146/options.html
http://www.autohome.com.cn/317/options.html
则获取为空,不知道是何原因,目前个人看是能获取的页面K数要小于不能获取的页
求各位高手帮忙,看是什么问题?  小弟用的是lnmp

确认html获取到了,但通过正则不能获取到指定部分(url html字节大时)

都在30~35k,不可能是获取的问题,肯定是你的正则写得有问题

看下你的正则吧,是不是有些情况无法匹配。你自己都说已经获取到HTML了,那问题很好定位了
