用fsockopen获取百度的搜索页
我用php的函数fsockopen和fwrite,fgets等命令可直接获得http://www.baidu.com主页的内容,但却不能获得http://www.baidu.com/s?wd=音箱&pn=20的内容,甚是苦闷,觉得是百度做了防范了,但奇怪的是我将浏览器中所有的缓存和cookie都清除掉了,直接用地址栏访问http://www.baidu.com/s?wd=音箱&pn=20,却能够直接获得内容,但用php函数获取,却怎么也不行。百度是怎么能够区别出浏览器访问和程序访问的呢?哪位达人能说说原因和指点下迷津吗。
我没更多分了,用钱买php解决方案也行啊
