need a code to use HTTP Proxies for a script

[megamania]

i want to code a script which uses HTTP Proxies to hide the server ip is this possible to do if so how ?? some guidance please

You just need to use cURL instead of file_get_content().

Ex:

$proxy = "66.96.200.39:80";
$proxy = explode(':', $proxy);
$url = "$_POST[1]";
$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HEADER, 1);

$exec = curl_exec($ch);

hi..
I send you some little steps to hide server ip... A common way to hid your ip address, is to use a proxy server to process your http requests. Setting up your browser to use a proxy server is easy enough, but setting up scripts and programs to use proxies can be a little harder.
If the proxy that you are using requires authentication, you will simply add the proxy authorization http header, in a manner similar to what is shown in the last php tutorial. Logging in to a proxy is done by combining the username and password, only separated by a single colon ":", then encoding it using base64, and send it in the Proxy-Authorization http header.
thank you

What language? As stated above, you could use cURL and just set the options to use a proxy via CURLOPT_PROXY. If you decide to do it in Python, you should check out the "Requests" class (which can be found here: http://docs.python-requests.org/ ). It's really robust and handles nearly all HTTP requests (GET, POST, PUT, DELETE, etc), cookies, and of course proxies.

Example:

import requests
response = requests.get("http://site.com/",headers={"accept":"application/json"},proxies={"http":"http://127.0.0.1:8888"})
if response.status_code == "200":
    print "Response is: " + response.text

It also has some cool options for handling binary data, JSON responses, and all that nifty little stuff. Python is also always a great option for web automation since it has tons of threading libraries and runs on any operating system (plus you don't have to compile all those dependencies ).

You just need to use cURL instead of file_get_content().
$proxy = "66.96.200.39:80";
$proxy = explode(':', $proxy);
$url = "$_POST[1]";
$ch = curl_init();


curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HEADER, 1);

Couple of things:
1) There's no call to curl_close() after curl_exec() and there should be.
2) If you're not going to sanitize $_POST[1], then why not just pass it directly?
3) There's no need to split the proxy up and make 2 separate calls, CURLOPT_PROXY accepts IPORT format.


The same code, but with the above corrections:

$sProxy = "127.0.0.1:8888";
$ch = curl_init($_POST[1]);
$c  = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$c  = curl_setopt($ch, CURLOPT_HEADER, 1);
$c  = curl_setopt($ch, CURLOPT_PROXY, $sProxy);
$x  = curl_exec($ch);
$c  = curl_close($ch);

The above isn't commented just for sake of consistency. A more elegant solution would be:

function fetchURL($sURL, $aOpt=array()) {
	/[b][/b]/ INITIALIZE CURL
	$ch = curl_init($sURL);
	/[b][/b]/ SET OPTIONS
	$c  = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
	$c  = curl_setopt($ch, CURLOPT_HEADER, 1);
	/[b][/b]/ IF OPTIONS HAVE BEEN PASSED, SET THEM (AND OVERRIDE ORIGINALS ABOVE)
	foreach ($aOpt as $sKey=>$sVal) { curl_setopt($ch, $sKey, $sVal); }
	/[b][/b]/ EXECUTE REQUEST
	$x  = curl_exec($ch);
	/[b][/b]/ CLOSE HANDLE
	$c  = curl_close($ch);
	/[b][/b]/ RETURN RESPONSE
	return($x);
}
?>

And then you'd call it like:

/[b][/b]/ OPTIONS FOR REQUEST
$aOpt  = array(CURLOPT_PROXY=>'127.0.0.1:8888', CURLOPT_HEADER=>0);
/[b][/b]/ TARGET URL
$sURL  = "ht[b][/b]tp[:/[b][/b]/dynupdate[b][/b].[b][/b]no-ip[b][/b].[b][/b]co[b][/b]m[b][/b]/[b][/b]ip.php";
/[b][/b]/ THE RESULT
$sData = fetchURL($sURL, $aOpt);
/[b][/b]/ DISPLAY IT
print($sData);

The last example being the best, because of the optional CURLOPT_X overrides that can be passed in $aOpt. In addition, it could be further improved by using a static handle ($ch) so that it re-uses the same handle each time instead of creating new ones. It should be noted that most of this response is intended for the OP, not an attempt to correct or insult you. My original goal was to point out the issues I noticed with that code, but instead it turned into simplifying the process as much as possible (which will hopefully benefit the OP).

Awesome, thanks for the corrections!
