I want to pull some html pice of code with some data from an external website with cURL, but a recived a null response. If I type the url in browser i get the data that i want but i need to do that from my app via cURL or file_get_contents();
This is my code :
$_awb = '888000074599';
$url = 'http://89.45.196.45';
$post_fields = ':8080/?id=8IM*8J*9K&NT='.$_awb;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
$result = curl_exec($ch);
curl_close($ch);
You should not be using CURLOPT_POSTFIELDS. You are trying to do a GET request with a query string, but postfields is intended for making POST requests.
So setting CURLOPT_URL to the proper (absolute) URL should work.
$url = "http://89.45.196.45:8080/?id=8IM*8J*9K&NT="
$nt = "888000074599";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url . $nt);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close ($ch);
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!
I'm trying to grab cookies from a remote host with a little script which works well:
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_COOKIE, TRUE);
// grab URL and pass it to the browser
$opt = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
I would like to know how I can pass them back to the client?
$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 $curl_scraped_page;
How would I make this continuously connect to this server?
I'm working on a bot for this site to improve the technology. Also, how would I authenticate cookies on the server, for example: I send a request to the server with this script using the certain cookies I would like to use.
There is an option called CURLOPT_COOKIEJAR where you can set the file that contains the cookie:
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');
Once you get the cookie you have to use the same $ch variable to keep the connection.
You can found a complete example of cURL usage here: http://blog.binacube.com/2014/08/complete-curl-example-login-proxy-and.html
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;

Post declaring the proxy settings in the php script file issue has been fixed.

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
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
