使用 php cURL 从文件头获取文件名
我有这个 php cURL 函数:
function curl_login($url,$data,$proxy,$proxystatus){
$fp = fopen("cookietlt.txt", "w");
fclose($fp);
$login = curl_init();
curl_setopt($login, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($login, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($login, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($login, CURLOPT_TIMEOUT, 40);
curl_setopt($login, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'on') {
curl_setopt($login, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($login, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($login, CURLOPT_PROXY, $proxy);
}
curl_setopt($login, CURLOPT_URL, $url);
curl_setopt($login, CURLOPT_HEADER, TRUE);
curl_setopt($login, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($login, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($login, CURLOPT_POST, TRUE);
curl_setopt($login, CURLOPT_POSTFIELDS, $data);
ob_start(); // prevent any output
return curl_exec ($login); // execute the curl command
ob_end_clean(); // stop preventing output
curl_close ($login);
unset($login);
}
function curl_grab_page($site,$proxy,$proxystatus){
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'on') {
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_URL, $site);
ob_start(); // prevent any output
return curl_exec ($ch); // execute the curl command
ob_end_clean(); // stop preventing output
curl_close ($ch);
}
curl_login('http://www.site.tdl/login.php','username=test&password=demo','','off');
curl_grab_page('http://www.site.tdl/1965.torrent','','off');
我需要从文件中获取文件名(http://www. site.tdl/1965.torrent)标题到变量中。
http://www.site.tdl/1965.torrent header:
Content-Disposition: attachment; filename="Linux.Mint.torrent"
Content-Type: application/x-bittorrent
Content-Length: 4525
因此输出将为 Linux.Mint。我怎样才能做到这一点?
谢谢!

}
curl_login('http://www.site.tdl/login.php','username=test&password=demo','','off');
curl_grab_page('http://www.site.tdl/1965.torrent','','off');
I need to get filename from file(http://www.site.tdl/1965.torrent) header into variable.
http://www.site.tdl/1965.torrent header:
Content-Disposition: attachment; filename="Linux.Mint.torrent"
Content-Type: application/x-bittorrent
Content-Length: 4525
So output will be Linux.Mint. How can I do that?
Thanks!

我知道这个问题有点老了,但我想稍微澄清一下
CURLOPT_HEADERFUNCTION
,我发现 php.net 上的文档很混乱。curl 将一次向标头回调函数发送一个标头。回调函数必须返回读取的字节数,否则curl将失败(请求将结束)
示例输出:
如果没有readHeader的返回,curl将在发送第一个标头后结束。
I know this question is kind of old, but I'd like to clarify
CURLOPT_HEADERFUNCTION
a bit, I found the documentation on php.net to be confusing.curl will send the header callback function one header at a time. The call back function must return the number of bytes read or else curl will fail (and the request will end)
Example output:
Without the return from readHeader, curl will end after the first header is sent.
您需要分配一个回调来读取标头。
You need to assign a callback to read the headers.
