php - curl 重定向，不起作用？

Question

我正在使用以下代码:

$agent= 'Mozilla/5.0 (Windows; U; Windows NT 5.1; pl; rv:1.9) Gecko/2008052906 Firefox/3.0';

$ch = curl_init();

curl_setopt($ch, CURLOPT_USERAGENT, $agent);

curl_setopt($ch, CURLOPT_URL, "www.example.com");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_HEADER, 0);

$output = curl_exec($ch);

echo $output;

但是它重定向到这样:

http://localhost/aide.do?sht=_aide_cookies_

而不是到 URL 页面。

谁能帮我解决我的问题？

Answer 1

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

http://docs.php.net/function.curl-setopt说:

CURLOPT_FOLLOWLOCATION
TRUE to follow any "Location: " header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent, unless CURLOPT_MAXREDIRS is set).
