我在两台不同的服务器上使用这个脚本:
function curlGetFileInfo($url, $cookies="default"){
global $_config;
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'serverpath/cookies/'.$cookies.'.txt');
$data = curl_exec($ch);
curl_close($ch);
if ($data === false) {
return 0;
}
//echo $data;
$info['filename'] = get_between($data, 'filename="', '"');
$info['extension'] = end(explode(".",$info['filename']));
if (preg_match('/Content-Length: (\d+)/', $data, $matches)) {
$info['filesize'] = (int)$matches[1];
}
return $info;
}
这些服务器具有相同的PHP版本和相同的PHP-Curl版本。curl结果有两个不同的头部:
有效的:

Cookie被正确设置(包含登录信息),而且其他简单的Curl功能正常工作。
另外,我执行了curl_getinfo($ch, CURLINFO_HTTP_CODE)并得到了以下结果:
有效的:200
无效的:302
有什么想法?
