先后 尝试fsockopen/curl等方法,获取header并判断执行,但都失败,请教各位。
------解决方案--------------------
3gabc.com就只有这么一句。
你也只能获取到这个,meta refresh是在浏览器上执行的!!!
------解决方案--------------------
因为3gabc.com就只有这么一句。
你在抓取页面后 “echo $contents;” 页面自然就重定向到http://www.3Gabc.com 了。
所以不能echo $contents; 而是用正则“preg_match("//is",$content, $matches)”
抓出转向地址,然后在curl这个转线地址,就可以抓到你要的内容了。
