用fsockopen获取百度的搜索页

Jun 23, 2016 pm 02:38 PM

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

添加 useragent 试试,

当然试过了,已经参照Fiddler2截获的数据进行了全模仿

我觉得是你网络有问题

字符集编码问题吧?

奇了怪了,用file_get_contents确实可行,但用我的方法只是百度不能获取,其他网址都成功,这是为什么呢?

字符集编码没问题,我已经反复试验过了,同样的编码,file_get_contents是可以的

不知道你是怎么写的

$fp = fsockopen("www.baidu.com", 80, $errno, $errstr, 30);$out = "GET /s?wd=音箱&pn=20 HTTP/1.1\r\n";$out .= "Host: www.baidu.com\r\n";$out .= "Connection: Close\r\n\r\n";fwrite($fp, $out);while (!feof($fp)) {  echo fgets($fp, 128);}fclose($fp);
