Does anyone know how to uncompress the contents of a gzip file that i got with curl?
for example: http://torcache.com/torrent/63ABC1435AA5CD48DCD866C6F7D5E80766034391.torrent
responded
HTTP/1.1 200 OK
Server: nginx
Date: Wed, 09 Jun 2010 01:11:26 GMT
Content-Type: application/x-bittorrent
Content-Length: 52712
Last-Modified: Tue, 08 Jun 2010 15:09:58 GMT

Cache-Control: max-age=2592000
Content-Encoding: gzip
Accept-Ranges: bytes
then the compressed gzip,
i tried gzdecode but doesn't work , gzeflate as well doesn't they simply don't get any response, and the contents of the 开发者_运维知识库files are no more than 2k
Just tell cURL to decode the response automatically whenever it's gzipped
curl_setopt($ch,CURLOPT_ENCODING, '');
Use gzdecode
:
<?php
$c = file_get_contents("http://torcache.com/" .
"torrent/63ABC1435AA5CD48DCD866C6F7D5E80766034391.torrent");
echo gzdecode($c);
gives
d8:announce42:http://tracker.openbittorrent.com/announce13:announce-listll42 ...
libcurl offers a feature that makes it decompress the contents automatically (if built with zlib).
See the CURLOPT_ACCEPT_ENCODING option: https://curl.haxx.se/libcurl/c/CURLOPT_ACCEPT_ENCODING.html
Have you tried setting the header stating that you accept gzip encoding as follows?:
curl_setopt($rCurl, CURLOPT_HTTPHEADER, array('Accept-Encoding: gzip,deflate'));
With a zlib Stream Wrapper:
file_get_contents("compress.zlib://http://torcache.com/" .
"torrent/63ABC1435AA5CD48DCD866C6F7D5E80766034391.torrent");
Have you tried gzuncompress
or gzinflate
?
gzdeflate
compresses, the opposite of what you want. To be honest, I can't figure out how gzdecode
differs from normal uncompressing.
There's also the cURL option CURLOPT_ENCODING
:
The contents of the "Accept-Encoding: " header. This enables decoding of the response. Supported encodings are "identity", "deflate", and "gzip". If an empty string, "", is set, a header containing all supported encoding types is sent.
It seems to mean it'll automatically decompress the response, but I haven't tested that.
You can do it with gzinflate (pretending that $headers contains all your HTTP headers, and $buffer contains your data):
if (isset($headers['Content-Encoding']) && ($headers['Content-Encoding'] === 'gzip' || $headers['Content-Encoding'] === 'deflate'))
{
if ($headers['Content-Encoding'] === 'gzip')
{
$buffer = substr($buffer, 10);
}
$contents = @gzinflate($buffer);
if ($contents === false)
{
return false;
}
}
