I am trying to use curl through a proxy, when I dont use a proxy it works fine but if I use a proxy it returns null, no error messages or anything.
I have already tried other opened questions but their answers are inconclusive.
Here is my code:
<?php
$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '122.117.225.161:8080';
//$proxyauth = 'user:pass';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
var_dump($curl_scraped_page);
?>
The proxy there is a free working proxy (I manually checked), I have also tried it with a private proxy (I used the user:pass authentication method) but still returns null.
Any information will be helpful.
Thanks!
Modern browsers support HTTPS proxies that can be connected to via a PAC file (see https://www.igvita.com/2012/06/25/spdy-and-secure-proxy-support-in-google-chrome/ if you're not familiar).
I'm trying to replicate the same thing and connect to such a proxy via php CURL, but I'm simply getting a blank response, no headers or content.
My code is as follows:
$url = "http://checkip.dyndns.com";
$proxy = "proxy.domain.com:443";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL , 1);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, 'test:test');
curl_setopt($ch, CURLOPT_PROXYTYPE, "CURLPROXY_HTTP");
$response = curl_exec($ch);
curl_close($ch);
echo $response;
Any ideas?
If anyone is interested, the solution to this is to use spdycat instead of curl: https://github.com/tatsuhiro-t/spdylay
There's no support for connecting to a proxy with HTTPS with curl yet. There is a work-in-progress branch in git though: https://github.com/bagder/curl/tree/HTTPS-proxy
We will appreciate help to get that in shape to merge.
I am using curl to extract some data of a website.First time it works perfectly , but now it not parse any data from the website.I think they are blocked my server ip.So I can use public proxy ip.But still it not working.My code is ,
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $urls);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, '3127');
curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP');
curl_setopt($ch, CURLOPT_PROXY, '204.93.54.15');
$original_file = curl_exec($ch);
curl_close($ch);
I can't get user name and password of public proxies.Is it important to set public proxy's username and password?It don't show any errors.Any one please help me.
Here is a good answer to use proxy in curl
How to use CURL via a proxy?
Please check this. If you have any queries feel free to ask.

Close your connection when you are done with it. That should do the trick.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $urls);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_PROXYPORT, '3127');
curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP');
curl_setopt($ch, CURLOPT_PROXY, '204.93.54.15');
$original_file = curl_exec($ch);
print_r($original_file);
curl_close($ch);
I'm working on a PHP script right now which sends requests to our school's servers to get real-time information about class sizes for different courses. The script runs perfectly fine when I don't use a proxy, returning a string full of course numbers and available seats. However, I want to make this a service for the students, and I'm afraid that if I make too many requests my ip will get blocked. So I'm attempting to do this through a proxy, with no success. As soon as I add the CURLOPT_HTTPPROXYTUNNEL and CURLOPT_PROXY fields to my requests nothing gets returned. I'm not even sure how to troubleshoot it at this point since I'm not getting an error message of any kind. Does anyone know what's going on or how to at least troubleshoot it?
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$proxy = explode(':', $proxy);
curl_setopt($ch, CURLOPT_PROXY, $proxy[0]);
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy[1]);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'tempcookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'tempcookie.txt');
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_REFERER, $ref);
$exec = curl_exec($ch);
echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
Proxy used for tests: 75.147.173.215:8080
I use the following code if I have to use a proxy with curl:
$proxy = "127.0.0.1:8080"; // or something like that
if($proxy !== null){
// no need to specify PROXYPORT again
curl_setopt($ch, CURLOPT_PROXY, $proxy);
// to make the request go through as though proxy didn't exist
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
}
You can set CURLOPT_STDERR and CURLOPT_VERBOSE curl options to save your errors in a file. Also, you may use curl_error() function. BTW, by default, curl should show all errors in STDERR.
Besides, for general check, you can simply specify selected proxy in you browser configuration properties, try to open specific service in browser and see, whether correct response is returned.
UPDATE:
CURLOPT_HTTPPROXYTUNNEL is used to make curl call CONNECT HTTP method when requesting proxy server (see here for details). I tested code without this option - it worked successfully.
Code I used:
$proxy = "75.147.173.215:8080";
$proxy = explode(':', $proxy);
$url = "http://google.com";
$ch = curl_init();
curl_setopt($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);
echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
Here is a well tested function which i used for my projects with detailed self explanatory comments
There are many times when the ports other than 80 are blocked by server firewall so the code appears to be working fine on localhost but not on the server , try using port 80 proxies
function get_page($url){
global $proxy;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
//curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_HEADER, 0); // return headers 0 no 1 yes
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return page 1:yes
curl_setopt($ch, CURLOPT_TIMEOUT, 200); // http request timeout 20 seconds
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // Follow redirects, need this if the url changes
curl_setopt($ch, CURLOPT_MAXREDIRS, 2); //if http server gives redirection responce
curl_setopt($ch, CURLOPT_USERAGENT,
"Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7");
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookies.txt"); // cookies storage / here the changes have been made
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookies.txt");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // false for https
curl_setopt($ch, CURLOPT_ENCODING, "gzip"); // the page encoding
$data = curl_exec($ch); // execute the http request
curl_close($ch); // close the connection
return $data;
}
I am processing credit cards using a payment gateway. To POST the data to their servers, I am using cURL in PHP. I have an SSL certificate issued to my domain, to ensure all POST'ed data is encrypted. Because the SSL certificate is already installed, do I still need to use the SSL options for cURL? If so, which of the options do I need to set given my setup?
I have tried the following code unsuccessfully:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://secure.paymentgateway.com/blah.php");
curl_setopt ($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_CAINFO, getcwd().'/cert/ca.crt');
curl_setopt($ch, CURLOPT_SSLCERT, getcwd().'/cert/mycert.pem');
curl_setopt($ch, CURLOPT_SSLCERTPASSWD, 'password');
curl_setopt($ch, CURLOPT_POST, $count);
curl_setopt($ch,CURLOPT_POSTFIELDS,"variables...");
$output = curl_exec($ch);
echo $output;
curl_close($ch);
Well you already disabled the verification (which I don't recommend: curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);). This opens you for Man-in-the-middle attacks.
