I am having big problems with accessing lots of https sites to download pages and especially files.
I have done multiple searches on the interweb over this problem and the bulk of them say the same thing:
use the following:
curl_setopt($ch, CURLOPT_SSLVERSION,3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);
But this never seems to work for me.
I have also tried downloading the SSL certificate but that does not help either.
I have also upgraded my curl lib to the very latest as I understand that could cause issues.
I am using PHP5, and it is not an option for me to upgrade above that.
Here is an example of my code and one of the urls I am trying to access:
<?php
$file_source="https://www.faa.gov/"
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $file_source);
curl_setopt($ch, CURLOPT_REFERER, $file_source);
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
curl_setopt($ch, CURLOPT_SSLVERSION,3);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,false);
$data = curl_exec ($ch);
$error = curl_error($ch);
curl_close ($ch);
?>
Can anyone please help as I am tearing my hair out over this.

This is working fine for me:
$fullurl="https://www.faa.gov/";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
curl_setopt($ch, CURLOPT_URL, $fullurl);
$returned = curl_exec($ch);
var_dump($returned);
curl_close ($ch);

I had working code that used my VPN (NordVPN) credentials through their SOCKS5 protocol.
Recently, they have dropped support for SOCKS5 so I have to use their other protocols, however I am unable to get any to work.
All of their available protocols can be seen here
https://nordvpn.com/servers/tools/
- IKEv2/IPSec
- OpenVPN
- Wireguard
- HTTP Proxy (SSL)
Here is my code, attempting to use their "HTTP Proxy (SSL)" protocol
$cookie_file = tempnam("/tmp", "CURLCOOKIE");;
$ch = curl_init();
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_ENCODING, "");
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120); // in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $agent);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP');
curl_setopt($ch, CURLOPT_PROXYPORT, "443");
curl_setopt($ch, CURLOPT_PROXY, "au643.nordvpn.com");
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyUser . ":" . $proxyPass);
curl_setopt($ch, CURLOPT_PROXYAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);
curl_setopt($ch, CURLOPT_URL, $Url);
$result = curl_exec($ch);
curl_close($ch);
The error I get is
curl_exec(): supplied resource is not a valid cURL handle resource in ...
I don't really care what protocol it is, just need it to work.
Thanks.
After facing the same issue, I have worked out a solution
$PROXY_HOST = "xxx.xxxxxx.com";
$PROXY_PORT = "89";
$PROXY_USER = "yourproxyusername";
$PROXY_PASS = "yourproxypassword";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_PROXY_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, "$PROXY_USER:$PROXY_PASS");
curl_setopt($ch, CURLOPT_PROXY, "https://$PROXY_HOST:$PROXY_PORT");
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response= curl_exec($ch);
$error = curl_error($ch);
echo $error;
echo $response;
curl_close($ch);
One thing to note is that for NordVPN you have to use the port 89 for HTTP Proxy (SSL) and the username and password is not your account username and password, but your proxy specific credentials that you can find on your account page.
Also dont quote me on this, but I think you need to use PHP 7.3+ for this to work.
we can use it with protonvpn or vpnbook ?
I'm having trouble understanding how CURL handles headers.
I have a site.com/page1 that I want to access with CURL it does a 308 redirect to site.com/page2/file.zip
What I need is to go through site.com/page1 with CURL but download site.com/page2/file.zip directly from site.com
I'm using this code but it does not work as expected. It accesses site.com/page1 redirects to site.com/page2/file.zip but opens the file in the browser
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $_cookie_file);
curl_setopt($ch, CURLOPT_COOKIEFILE, $_cookie_file);
curl_setopt($ch, CURLOPT_REFERER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_exec($ch);
$error = curl_getinfo($ch);
curl_close($ch);
I guess if I can keep the response headers I'll fix the problem. But how do I do it ?? How do I use the same headers for the CURL visitor that the site I am accessing is sending me.
You want the cURL option RETURNTRANSFER set to true so what is returned comes back to you. Since you are trying to save a ZIP file you'll also need to open a file and use the CURLOPT_FILE option to tell cURL where to save your ZIP file.
curl_setopt ($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt ($ch, CURLOPT_TIMEOUT,'180'); # 3 minute timeout
$FileOut = fopen('MyZIP_File.zip','w') or die('Could not open the output data file');
curl_setopt ($ch, CURLOPT_FILE,$FileOut);
curl_exec ($ch);
fclose($FileOut) or die('We ran into a problem saving data file');
This solved the problem.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEJAR, $_cookie_file);
curl_setopt($ch, CURLOPT_COOKIEFILE, $_cookie_file);
curl_setopt($ch, CURLOPT_REFERER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, true);
$result = curl_exec($ch);
if (preg_match('~Location: (.*)~i', $result, $match)) {
$location = trim($match[1]);
header('Location:' . $location);
}
I have the following small cURL PHP Script which has to follow an ASP link:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://partners.webmasterplan.com/click.asp?ref=<ID>&site=14910&type=text&tnb=2');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie_jar.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie_jar.txt');
$page= curl_exec($ch);
curl_close($ch);
?>
But I only get:
The requested URL /click4.aspx was not found on this server.
Has anybody got an idea as to what am I doing wrong?
My CURL redirect is not working i am redirected to same page but the same page is empty when it is rendered after i submit it. Here is my code.
$ch = curl_init("http://localhost/soft/entercode.php");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'variable1=abc&variable2=123');
$result = curl_exec($ch);
curl_close($ch);
look into the configurations cause this error is sometime caused by installed CURL check that if the installation files have all the required files for win 32 version of CURL.
Try adding and changing:
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
Hope it works for you
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://localhost/soft/entercode.php");
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,2);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'variable1=abc&variable2=123');
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_MAXREDIRS,1);
$buffer = curl_exec($ch);
curl_close($ch);
Check this it will work ..
I am looking to set curl to use a proxy server. The url is provided by an html form, which has not been a problem. Without the proxy it works fine. I have found code on this and other sites, but they do not work. Any help in finding the correct solution would be much appreciated. I feel that the bellow are close, but that I am missing something. Thank You.
The bellow code I adapted from here http://www.webmasterworld.com/forum88/10572.htm but it returns an error message about a missing T_VARIABLE on line 12.
<?
$url = '$_POST[1]';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1)
curl_exec ($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
echo '<br />';
print_r($curl_info);
?>
The bellow is from curl through proxy returns no 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);
$exec = curl_exec($ch);
echo curl_error($ch);
print_r(curl_getinfo($ch));
echo $exec;
?>
is currently live on pelican-cement.com but also does not work.
UPDATE:
Thank you for all your help, I made the above changes. Now it only returns a blank screen.
<?
$url = $_POST['1'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 0);
curl_setopt($ch, CURLOPT_PROXY, '66.96.200.39:80');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST,'GET');
curl_setopt ($ch, CURLOPT_HEADER, 1);
curl_exec ($ch);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
?>
Here is a working version with your bugs removed.
$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
//$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
I have added CURLOPT_PROXYUSERPWD in case any of your proxies require a user name and password.
I set CURLOPT_RETURNTRANSFER to 1, so that the data will be returned to $curl_scraped_page variable.
I removed a second extra curl_exec($ch); which would stop the variable being returned.
I consolidated your proxy IP and port into one setting.
I also removed CURLOPT_HTTPPROXYTUNNEL and CURLOPT_CUSTOMREQUEST as it was the default.
If you don't want the headers returned, comment out CURLOPT_HEADER.
To disable the proxy simply set it to null.
curl_setopt($ch, CURLOPT_PROXY, null);
Any questions feel free to ask, I work with cURL every day.
I have explained use of various CURL options required for CURL PROXY.
$url = 'http://dynupdate.no-ip.com/ip.php';
$proxy = '127.0.0.1:8888';
$proxyauth = 'user:password';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url); // URL for CURL call
curl_setopt($ch, CURLOPT_PROXY, $proxy); // PROXY details with port
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxyauth); // Use if proxy have username and password
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5); // If expected to call with specific PROXY type
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); // If url has redirects then go to the final redirected URL.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0); // Do not outputting it out directly on screen.
curl_setopt($ch, CURLOPT_HEADER, 1); // If you want Header information of response else make 0
$curl_scraped_page = curl_exec($ch);
curl_close($ch);
echo $curl_scraped_page;
