I am trying to execute this simple script in php:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0); // no headers in the output
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // output to variable
curl_setopt($ch, CURLOPT_PROXYPORT, $proxy_port);
curl_setopt($ch, CURLOPT_PROXYTYPE, 'HTTP');
curl_setopt($ch, CURLOPT_PROXY, $proxy_ip);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $opts['credentials']);
$data = curl_exec($ch);
curl_close($ch);
echo $data;
I don't know if this is a problem with some tipe of TimeOut or it needs another paramter but sometimes brings the page and others not, why this happens?
Wath I did is checked errors with "curl_error", that led me to the problem.
Thanks.

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:' . $location);
}
Very simple code in PHP, that looks like this:
curl_setopt($ch, CURLOPT_URL, "http://[heres url]");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('keycode: [heres keycode]'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
var_dump(json_decode($output, true));
// echo $output; doesn't work as well
[heres url], [heres keycode] - url and keycode are correct
If I run the same script in a app (for example I am using a chrome app named Advanced REST Client) - everything works.
In my PHP script the result is either empty or NULL.
What could be the problem? Thanks.
$url='https://randomuser.me/api/';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION , 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER,array('keycode: [here value]'));
curl_setopt($ch, CURLOPT_URL,$url);
$html = curl_exec($ch);
var_dump(json_decode($html, true));
I am using below code to post a file to third party API -
$post = array('userName' => 'testabc','password'=>'testabc','FILE1'=>'abc.csv','cn'=>'10215');
$fp = fopen("orders/abc.csv", 'r');
$ch = curl_init("https://differentdomain.com/abc.cgi");
curl_setopt($ch, CURLOPT_USERPWD, "myuser:mypwd");
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400);
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_PROGRESSFUNCTION, 'CURL_callback');
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize("orders/abc.csv"));
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$suc = curl_exec ($ch);
echo "==>".curl_error($ch);
echo "-->".$suc; die;
It returns with 500 Internal Server Error. Not sure whether the way I am posting parameters are right or wrong.
Any help appreciated.
Thanks.
Upload image using curl
Try this
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;
