[英]With php cURL get filename from file header
I have this php cURL function: 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 ($ch);
}
curl_login('http://www.site.tdl/login.php','username=test&password=demo','','off');
curl_grab_page('http://www.site.tdl/1965.torrent','','off');
I need to get filename from file( http://www.site.tdl/1965.torrent ) header into variable. 我需要从文件( http://www.site.tdl/1965.torrent )标题中获取文件名到变量。
http://www.site.tdl/1965.torrent header: http://www.site.tdl/1965.torrent标题:
Content-Disposition: attachment; filename="Linux.Mint.torrent"
Content-Type: application/x-bittorrent
Content-Length: 4525
So output will be Linux.Mint. 因此输出将是Linux.Mint。 How can I do that?
我怎样才能做到这一点?
Thanks! 谢谢!
I know this question is kind of old, but I'd like to clarify CURLOPT_HEADERFUNCTION
a bit, I found the documentation on php.net to be confusing. 我知道这个问题有点陈旧,但我想澄清一下
CURLOPT_HEADERFUNCTION
,我发现php.net上的文档令人困惑。
curl will send the header callback function one header at a time. curl会一次发送一个标头回调函数。 The call back function must return the number of bytes read or else curl will fail (and the request will end)
回调函数必须返回读取的字节数,否则curl将失败(请求将结束)
curl_setopt($ch, CURLOPT_HEADERFUNCTION, "readHeader");
function readHeader($ch, $header)
{
// read headers
echo "Read header: ", $header;
return strlen($header);
}
Example output: 示例输出:
Read header: HTTP/1.1 200 OK
Read header: Server: nginx/0.8.32
Read header: Date: Wed, 31 Mar 2010 14:23:18 GMT
Read header: Content-Type: image/jpeg
Read header: Content-Length: 886308
Read header: Connection: close
Read header: Accept-Ranges: bytes
Read header:
Without the return from readHeader, curl will end after the first header is sent. 如果没有readHeader的返回,curl将在发送第一个头之后结束。
You need to assign a callback to read the headers. 您需要指定一个回调来读取标题。
curl_setopt($ch, CURLOPT_HEADERFUNCTION, readHeader);
function readHeader($ch, $header)
{
// read headers
}
