I have to tell my php to use proxt settings to allow a connection with website. So how can I force php script to use proxy?
I scraped some HTTP proxy and I want to use them.
I tried adding this to config.php
stream_context_set_default(['http'=>['proxy'=>'101.66.253.22:8080
']]);
I also tried to change function from this:
$ch = curl_init(Site::LINK_LOGIN);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_ENCODING, "UTF-8");
curl_setopt($ch, CURLOPT_POST, 1);
to this:
$ch = curl_init(Site::LINK_LOGIN);
curl_setopt($ch, CURLOPT_PROXY, '101.66.253.22:8080');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_ENCODING, "UTF-8");
curl_setopt($ch, CURLOPT_POST, 1);
But none of wchich works properly. Can you help me?
Try to make a new curl_setopt with proxy port.
curl_setopt($ch, CURLOPT_PROXY, "http://proxy.example.com"); //proxy url
curl_setopt($ch, CURLOPT_PROXYPORT, "8080"); // proxy port number
Maybe...
But first check the error message
if(curl_exec($ch) === false)
{
echo 'Curl error: ' . curl_error($ch);
}
else
{
echo 'Operation completed without any errors';
}

I am trying to connect a website with CURL using a proxy in PHP. But I get "Received HTTP code 400 from proxy after CONNECT" error.
This is the code that I use to connect:
<?PHP
$ch = curl_init("https://ipinfo.io/json");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_PROXYTYPE, "HTTP");
curl_setopt($ch, CURLOPT_PROXY, "207.154.231.213:8080");
$output = curl_exec($ch);
if(curl_errno($ch))
echo curl_error($ch);
echo $output;
?>
I don't know what the problem is. The proxy should work perfectly because I check it.
use nex code
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, "https://ipinfo.io/json");
$result=curl_exec($ch);
curl_close($ch);
echo json_decode($result, true);
I recommend http://docs.guzzlephp.org/ library for apis for better practices
Based on the documentation curl_setopt you should either remove your CURLOPT_PROXYTYPE setting (to use the default CURLPROXY_HTTP), or you need to change your invalid setting
curl_setopt($ch, CURLOPT_PROXYTYPE, "HTTP");
to
curl_setopt($ch, CURLOPT_PROXYTYPE, "CURLPROXY_HTTP");
Note that the type HTTP does not exist.
When I run the below code on server it only shows the blank page and suddenly stop further execution, I also checked the cUrl on server which is installed.
Here is my code.
$ftp_server = 'ftps://'.'server/Voorraadtonen link.csv';
$ch = curl_init(str_replace(" ","%20",$ftp_server));
curl_setopt($ch, CURLOPT_URL, $ftp_server);
curl_setopt($ch, CURLOPT_USERPWD,'username'.':'.'password');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_FTP_SSL, CURLFTPSSL_TRY);
curl_setopt($ch, CURLOPT_FTPSSLAUTH, CURLFTPAUTH_TLS);
//curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_PORT, 990);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0');
curl_setopt($ch, CURLOPT_VERBOSE,true);
$output = curl_exec($ch);
$error_no = curl_errno($ch);
echo $output; exit;
Latest update!
You have more than 1 errors in your codes,
you are using FTPS in url which requires SSL verification, and its false in
your codes.
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
//Dont use try! you shouldnt use
curl_setopt($ch, CURLOPT_FTP_SSL, CURLFTPSSL_TRY);
They should be true : SSL doesnt support true so they should be like following on #dharman warn in another answer.
But turning ssl true will require another setup like cacert file
etc. lik so
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
//and include cacert.pem
curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
Download cacert file here : https://curl.haxx.se/docs/caextract.html
2.Your url is not a true url $ftp_server = 'ftps://'.'server/Voorraadtonen link.csv';, this url will get nothing, but it should return an error atleast in error_log file, as you said all errors reporting are enabled
3.Your code should look like this
$curl = curl_init();
$file = fopen("link.csv", 'w');
curl_setopt($curl, CURLOPT_URL, "ftp://ftp.site.com/link.csv");
//Make sure for correct url
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($curl, CURLOPT_CAINFO, dirname(__FILE__) . '/cacert.pem');
//Make sure for correct url
curl_setopt($curl, CURLOPT_FILE, $file);
curl_setopt($curl, CURLOPT_USERPWD, "$_FTP[username]:$_FTP[password]");
//Make sure for your ftp credentials
curl_setopt($curl, CURLOPT_TIMEOUT, 20); //20 seconds will be enough
curl_exec($curl);
echo curl_errno($ch);
echo curl_error($ch);
curl_close($curl);
fclose($file);
1 more thing left headers should not be required but in case its required.
curl_setopt($curl, CURLOPT_HEADER, false); //Or
curl_setopt($curl, CURLOPT_HEADER, true);
Now it should work without any problem
NOTE : Example code is a working example you can edit it to your requirements
UPDATE : After modification you said you did in your codes (Still not showing us), finaly we get an error. once again I am asking you to add modified code into your question.
Error_no 28 cURL error 28: Connection timed out
the cURL 28 error occurs when the cURL request isn’t completed in a certain amount of time.
This happens when the cURL timeout value is set too low or when a firewall is blocking the cURL request.
Another possibility is a security module, for example the Apache mod_security module.
To fix the cURL error 28 you can contact your hosting provider.
So basicaly!
Your server is blocking. your credentials not match to required
credentails. SSL is required by server, but you are not setting it up.
Your function runing max of your Server Memory Limits settings.
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "ftp.site.com/link.csv");
//make sure your path to file is correct
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_USERPWD, "$_FTP[username]:$_FTP[password]");
//make sure your login credentials correct
curl_setopt($curl, CURLOPT_TIMEOUT, 500);
//Set timeout for connection
curl_exec($curl);
echo curl_errno($ch);
echo curl_error($ch);
//Get errors
curl_close($curl);
//Importand close curl connection.
I try to connect to socks5 proxy using libcurl, however I receive the answer SOCKS: authentication failed. I also tried to connect to the proxy server through a Powershell script with cURL – it works, so the proxy server is available and my login and password are correct. I tried a lot of solutions... But connection via PHP-script still does not work.
PHP version – 5.4, cURL version – 7.19. What can I do?
[UPDATE] Here is my current code. I want to send message with my Telegram bot :)
$proxy = '<hostname>:<port>';
$proxy_auth = '<username>:<password>';
$url = 'https://api.telegram.org/bot<botID>/sendMessage?'.'chat_id='.$chat_id.'&parse_mode='.$parse_mode.'&text='.'test';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxy_auth);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, true);
$curl_scraped_page = curl_exec($ch);
$error = curl_error($ch);
echo $error;
echo $curl_scraped_page;
curl_close($ch);
Here is the complete answer for anyone else having the same issue.
//Curl setup
$url = "https://google.com";
$proxy = "10.23.2.2:8080";
$password = "username:secret_passowrd";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_SOCKS5);
curl_setopt($ch, CURLOPT_HEADER, true);
//proxy's address
curl_setopt($ch, CURLOPT_PROXY, $proxy);
//proxy's password
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $password);
//in order to follow redirects.
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
//in order to use the result of the query
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//run query
$curl_scraped_page = curl_exec($ch);
$error = curl_error($ch);
echo $error;
echo $curl_scraped_page;
curl_close($ch);
Hope that helps.
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!
This randomly started happening again on my development computer. It works fine on the production server, so whatever. But I still need to test this here.
Could not resolve host: (hostname); Host not found.
I know about the security vulnerabilities with these settings. But right now, I care more about getting this to work. HTTP addresses of course work fine, but those with HTTPS return no content and give an error about not being able to find the hostname. I've searched and didn't find anything useful this time.
function useCurl($xml,$cert,$host){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$host);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
curl_setopt($ch, CURLOPT_SSLCERT, $cert);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
$result = curl_exec($ch);
if (curl_error($ch)) {
print "cURL error: ". curl_error($ch) ."\n<br/>";
}
curl_close($ch);
return $result;
}
Have you tried adding curl_setopt($ch, CURLOPT_PORT, 443); so that it connects to the server on the ssl enabled port?
