how to curl and proxy download

[musa]

nice sending pm

[PyroStrex]

Today, my co-worker (MediaStar), told me about this thread and now i'm interested.

why didn't you just ask us directly in the first place?

So, since knowledge is for sharing, first, we don't use PHP but we use NodeJS.

Second, we uses NodeJS's fs.pipe to pipe the server request response directly to the client.

As the documentation inside NodeJS said, pipe was done by pausing and resuming the response (ex: filehosting) whenever necessarily while writing to the client at the same time. Just imagine, whenever our server writes data to the client, our server will pause the download for a moment, then when finished writing, our download will resume. The process will repeat until the download finished.

So, I think in PHP, you can do the same by following the same algorithm but just requires some extra works.

Hope this helps, next time, ask directly.

Sincerely, PyroStrex.

your co-worker did not responded to my pm./

anyway.

fuck about your shit "secrets", here it is, to sum up:

1) cURL login and form and parse the output to get the download link and the member cookie:
curl_setopt($ch, CURLOPT_COOKIEFILE, "the_cookie.txt");

2) open a socket on the download link,:
$fp = @fsockopen($host, $port, $errno, $errstr, 3);
3) putting the right headers/cookies in it:
fputs($fp, $your_headers);
including cookie:
$your_headers .= "Cookie: PHPSESSID=".$session."; key=".$var."\r\n";
(you can read the cookie's keys/values preg_match()'ing from the cookie.txt)
4) then output the stream to the visitor:
while (!feof($sock)){
echo fread($sock, 8192);
}
fclose($sock);



kthxba?

mfw those who know don't respond to my pm -->
mfw i post the response here --> x'D

sry for my bad english

Great to have a new useful member!

That is what I meant with "PHP isn't the best language for this".
NodeJS however, is (perfect).

@musa; I'm sorry I didn't respond.
If you wanted the fsocket method instead of the curl you should've just said so
Anyway; I made you a little something. Happy x-mas!
It could be that you're only interested in the '//The actual shit' -part.

It is weird though, you used many bad words in your reply, was my reply really that heart piercing? because actually, I am telling you in a professional way and even signed up for you just to give you answer. So, just to tell you, this is really not what I expected from a person who ask for an answer. I even tried my best to help you because I know, I've been at your place last time. If i'm wrong, then correct me but this will be the last time I will reply to this thread. Thank you.

Great to have a new useful member!

Haha, thank you.

hahaha, did u even read my response? you are posting a code i already found without your so called help and i posted just on top of your message

btw i just asked for a clue or a function name that would do the streaming, i dont need your full code as i know about curl'ing and parsing the responses through preg_match and regex...

thanks anyway but the fact that unplease me is that you act like your helping but you just posting way after i found it already and ignoring my pm

bye.

[futureawesome]

musa why'd you pm me to code you something that is obvious? The method has been said before in many threads, if you can't take the method and TRY to implement it yourself you shouldn't be in this section. Let alone bashing people who did help you.

@RobinH yours looks nicer than mine haha. Although I'm using fopen vs fsockopen... is there a major difference?

[Robin H]

I don't know the difference between fopen and fsockopen.
They both give a stream, but I'm not sure you can send custom headers with fopen..

[pokerface]

fopen() can only open certain streams and protocols (file, stdin, http etc). With fsockopen() you can customise everything you're requesting from or posting to the other party, even write IRC bots etc, since it's a socket. There's an awesome head-first guide on sockets: http://www.tuxradar.com/practicalphp/15/1/0
