我想用php采集一个网站的数据，但是无法获取该网站的数据。网址如下：
http://www.alldatasheet.com/view.jsp?Searchword=78HC
希望您能试一下，只要能返回数据就行了。我试了很久不能成功。
回复讨论(解决方案)
$header = array ( "GET /view.jsp?Searchword=78HC HTTP/1.1","Host: www.alldatasheet.com","Connection: keep-alive","Cache-Control: max-age=0","Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8","User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.152 Safari/537.22","Accept-Encoding: gzip,deflate,sdch","Accept-Language: en-US,zh-CN;q=0.8,zh;q=0.6","Accept-Charset: UTF-8,*;q=0.5","Cookie: JSESSIONID=BD1418BC3F4CA9084F0C022A98687A09; track_id=117.25.173.111363310326444; seekstr=*78H*..; seekshot=78H..1..75..8..112; __utma=191189370.2036196682.1363308553.1363308553.1363308553.1; __utmb=191189370.3.10.1363308553; __utmc=191189370; __utmz=191189370.1363308553.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); arp_scroll_position=900"); // 初始化一个 cURL 对象$curl = curl_init(); // 设置你需要抓取的URLcurl_setopt($curl, CURLOPT_URL, 'http://www.alldatasheet.com/view.jsp?Searchword=78HC');curl_setopt($curl, CURLOPT_HTTPHEADER, $header); //设置header // 设置header显示方式curl_setopt($curl, CURLOPT_HEADER, 0); // 设置cURL 参数，要求结果保存到字符串中还是输出到屏幕上。curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 运行cURL，请求网页$data = curl_exec($curl); // 关闭URL请求curl_close($curl); // 显示获得的数据var_dump($data);
只要是浏览器能访问的页面，应该都能采集的。
关键是cookie。
