卷曲问题,无法下载完整网页
使用此代码,我尝试下载此网页: http://www.kayak.com/s/...
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://www.kayak.com/s/search/air?ai=kayaksample&do=y&ft=ow&ns=n&cb=e&pa=1&l1=ZAG&t1=a&df=dmy&d1=4/10/2010&depart_flex=exact&r1=y&l2=LON&t2=a&d2=11/10/2010&return_flex&r2=y');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_REFERER,"http://wwww.google.com");
$content = curl_exec ($ch);
echo $content;
您可以在以下位置查看演示:http://www.pointout.org/test.php
正如您所看到的,带有价格的部分丢失了。
可能出什么问题了?

You can see the demo at: http://www.pointout.org/test.php
As you can see the part with prices is missing.
What could be wrong?

这不会像你想象的那样工作。原因是价格不在您收到的初始 HTML 响应中。相反,发生了一些 Javascript 魔法,即在加载页面时使用 AJAX 来加载价格。
This is not going to work the way you think it will. The reason is the prices are not in the initial HTML response that you get. Rather, there is some Javascript magic occurring which is using AJAX to load the prices when the page is loaded.
